Floating bridges were historically constructed using wood. Pontoons were formed by simply lashing several barrels together, by rafts of timbers, or by using boats. Each bridge section consisted of one or more pontoons, which were maneuvered into position and then anchored underwater or on land. The pontoons were linked together using wooden stringers called balks.
|
|
The water depth below the pontoons ranges from . In its marine environment, the bridge is exposed to tidal swings of . The pontoons for the bridge were fabricated in the Duwamish Waterway in Seattle; during fabrication, two of the pontoons sank. When they were attached for the first time, and then towed into place and anchored, sea conditions in the Hood Canal were too severe and the pontoons were returned to a nearby bay until a better method of attaching could be devised.

Wooden pontoons and India rubber bag pontoons shaped like a torpedo proved impractical until the development of cotton-canvas covered pontoons, which required more maintenance but were lightweight and easier to work with and transport. From 1864 a lightweight design known as Cumberland Pontoons, a folding boat system, were widely used during the Atlanta Campaign to transport soldiers and artillery across rivers in the South. In 1872 at a military review before Queen Victoria, a pontoon bridge was thrown across the River Thames at Windsor, Berkshire, where the river was wide. The bridge, comprising 15 pontoons held by 14 anchors, was completed in 22 minutes and then used to move five battalions of troops across the river.

Semi-submersible marine structures are typically only movable by towing. Semi-submersible platforms have the principal characteristic of remaining in a substantially stable position, presenting small movements when they experience environmental forces such as the wind, waves and currents. Semi-Submersible platforms have pontoons and columns, typically two parallel spaced apart pontoons with buoyant columns upstanding from those pontoons to support a deck. Some of the semi-submersible vessels only have a single caisson, or column, usually denoted as a buoy while others utilize three or more columns extended upwardly from buoyant pontoons.

The floating bridge is laid atop 77 concrete pontoons that float above the water and are secured by 58 anchors to the lake bottom. Of the pontoons, 21 are longitudinal pontoons that support the deck and structure and are and weigh ; 54 smaller supplemental pontoons, weighing , are used to stabilize the weight of the bridge; and two "cross" pontoons, weighing , are sited at each end of the floating span at transitional spans, which connect the deck to fixed bridges and approaches using hinges to move up to for fluctuations in lake water levels moving the pontoons. All the pontoons are designed with watertight compartments that are monitored remotely with sensors to detect leaks that could lead to catastrophic failure. The bridge's 58 anchors all feature , steel cables and are divided into three types: 45 fluke anchors used in softer soils deep in the lakebed; eight gravity anchors used in solid soils nearer to the shore; and five , drilled shaft anchors used in conjunction with the gravity anchors to prevent navigation hazards.

In 2012, WSDOT identified cracks and other problems with the first batch of completed pontoons, estimating that it would cost $400 million to repair cracks and other flaws that would bring down the bridge's predicted lifespan below the desired 75 years. The problems stemmed from shortcuts allegedly taken by contractors to complete pontoons to meet set deadlines; the proposed solutions to fix the pontoons included adding high-tension steel cables and post-tensioning of the concrete. A floating, cofferdam was launched in November 2013 to assist in repairs of the pontoons, functioning as a portable drydock that wrapped around parts of the pontoons. The repairs were made by contractors from December 2013 to June 2014 and cost a total of approximately $208 million, using up the majority of the program's reserve funds.

The toll rate increase and nighttime toll was approved by the commission and implemented on July 1, 2017. The old bridge was planned to be decommissioned by floating away pontoons to an industrial site in Kenmore for disposal and recycling; in March 2016, the city rejected the plan, citing the possible release of toxins in the pontoon's concrete. The pontoons were sold to a recycling company based in Gig Harbor which plans to reuse the individual pontoons for floating decks and other projects. An unaffiliated contest was held in 2012 seeking ideas for the 33 pontoons of the old bridge, with solutions ranging from a "floating High Line" to partial submersion for walking paths.

There are a number of floating versions of the Mabey LSB in use across Iraq: Floating Piers which consist of steel Flexifloat pontoon units, Landing Piers consisting of 16 pontoon units, and Intermediate Piers which consist of 8 pontoons each. Hand winches are mounted on steel trays which are bolted to the pontoons. The anchors are connected to the hand winches and pontoons via steel chain and polypropylene ropes. Special span junction decks allow for the rotation of the floating spans as the spans deflect under live load.
|
|
If the maximum load of a bridge section is exceeded, one or more pontoons become submerged. Flexible connections have to allow for one section of the bridge to be weighted down more heavily than the other parts. The roadway across the pontoons should be relatively light, so as not to limit the carrying capacity of the pontoons. The connection of the bridge to shore requires the design of approaches that are not too steep, protect the bank from erosion and provide for movements of the bridge during (tidal) changes of the water level.
|
|
The pontoons are manufactured from high tension steel and they are atmospheric corrosion- and saltwater-resistant. Each pontoon has 5 independent water tight compartment with maintenance hole. The bottoms of the pontoons are reinforced for rough terrain operation. The power for the pontoon tracks is provided by an excavator engine and main hydraulic pumps with traveling motors.

The tuna that are located are purse seined, and then transferred through underwater panels between nets to specialised tow pontoons. They are then towed back to farm areas adjacent to Port Lincoln at a rate of about 1 knot; this process can take several weeks. Once back at the farm sites, the tuna are transferred from the tow pontoons into diameter farm pontoons. They are then fed bait fish (usually a range of locally caught or imported small pelagic species such as sardines) six days per week, twice per day and "grown out" for three to eight months, reaching an average of .

The pontoons were anchored in place by guy ropes to deadmen on shore, and by iron rods driven into the coral. Connecting tie pieces ran across the tops of the pontoons to hold them together into a pier. Despite extremely heavy weather on several occasions these pontoon piers stood up remarkably well. They gave extensive service, with little requirement for repairs.

The Taiping rebels made extensive use of pontoons on the Yangtze in their campaign against the Qing Dynasty in the Yangtze Basin. In December 30, 1852, they built two pontoons nearly 3,000 meters long in a fortnight's time at Baishazhou and Yingwuzhou in Wuhan to move troops from Hanyang on the north bank to the Wuchang on the south bank. The Taipings tied together small boats into twos and threes and steered these preassembled pieces simultaneously into the river, and used iron anchors to set the pontoons instead of chains. They added leather-covered walls to the bridges and added towers and firing positions.

In the 1970s Harris Flotebote pontoons were early adopters of sterndrives, and had motor-pods capable of holding engines as powerful as 140 horsepower—which enabled Harris Pontoons to pull water-skiers, an early innovation for pontoon boats. The splash guard added to the front of the pontoons, referred to as a “dolphin-nose cone” were implemented in 1959, this design feature has become standard within the industry. In 2005 Harris-Kayot was purchased by Brunswick Corporation. To meet market demand, Brunswick Fort Wayne Operations, the producer of Harris FloteBote expanded their production facility in June 2013 to a 360,000-square foot manufacturing campus in Fort Wayne, Indiana.

The pontoon effect refers to the tendency of a vessel whose flotation depends on lateral pontoons to capsize without warning when a lateral force is applied. The effect can be sudden and dramatic because pontoon boats usually cannot rely on the righting effect of a keel (which contains ballast). The vessel is stable and self-righting up to the point that the centre of gravity shifts past the centre of buoyancy of the ship and the vessel rapidly capsizes. (The same term can also arise when describing a design in which the attributes of a pontoon are created without using explicit pontoons—when a design effectively incorporates pontoons.

The pontoons have hydro-pneumatic fenders on both sides to facilitate high energy absorption and low reaction loads. Two vertical roller fenders are located at the forward and aft corners, on the side, for corner protection. They are intended for berthing vessels having displacement up to 40,000 tons on a jetty by serving as spacers between the jetty and the ship.Tender Pontoons Gangways They were built as part of an order to also construct one Service Barge Pontoon and four gangways.

M4T6 pontoon bridge 1983 Pontoon bridges were extensively used by both armies and civilians throughout the latter half of the 20th century. From the Post-War period into the early 1980s the U.S. Army and its NATO and other allies employed three main types of pontoon bridge/raft. The M4 bridge featured a lightweight aluminum balk deck supported by rigid aluminum hull pontoons. The M4T6 bridge used the same aluminum balk deck of the M4, but supported instead by inflatable rubber pontoons.
|
|
The decision to construct the bridge was taken by parliament on 9 December 1987, but they demanded that a larger ship channel be constructed. Detailed planning started in March 1990, and at first two technical methods for constructing the pontoon bridge were considered: a continuous concrete floating caisson between the abutments, and a steel version incorporating a truss bridge carrying concrete pontoons. However, they were both rejected in favor of a concrete or steel box section borne on concrete pontoons.

To replace the P61's subframe the side pontoons of the P261 chassis were extended behind the driver's seat, and the engine was mounted between them. Within the pontoons, rubber cells were used to retain fuel. This caused complications early in the P261's life, as BRM's new, high-exhaust version of the P56 V8 engine was not ready for the start of the 1964 season, and holes had to be cut in the pontoons to allow the exhaust pipes of the older, low-exhaust version to pass through them. The centre exhaust engine appeared at the 1964 Italian Grand Prix in Graham Hill's new chassis "2616" and this and "2617", which was Jackie Stewart's regular car in 1965, were the only two P261s which did not have the exhaust slots.

The new bridge was designed to be more stable in stronger winds and raised the bridge deck much higher above the surface of the lake than the old bridge. Unlike the original floating bridge, where the road surface is directly on pontoons connected end-to-end, the new bridge featured pontoons laid north–south, perpendicular to the direction of vehicular traffic, and a road surface on a platform raised above the water. This design now includes shoulders and a protected pedestrian and bicycle path across the viaduct.
|
|
A particular feature of the design by the Naval Architects was that there was no cross-bracing between the pontoons. Instead, the platform was given extra strength by a box-girder construction and diagonal bracing was arranged from the centre of the platform to the pontoons. This arrangement remained virtually unchanged to the build completion and offered exceptional speed when the vessel was de-ballasted on the surface. The intention was to achieve a rapid response to emergencies, wherever they might be experienced in the North Sea.

The floating section is a steel box girder bridge with ten pontoons, which because of the fjord's depth are not laterally anchored. The roadway sits on an orthotropic deck. The pontoons and the cable- stayed bridge are built in concrete, with the main span being supported with 48 cables. The fjord end of the main span is supported by a deep foundation, where the two bridges meet. From there and for , the roadwall has a 5.7 percent gradient on a viaduct anchored to the pontoon bridge.

Skis and pontoons were also available options, although the Sportster's vertical tail had to be enlarged to maintain its spin certification in case pontoons were fitted. A Deluxe model included wheel pants, navigation lights, radio, and optional skylights; later modifications to the design included a one-piece windshield. Initial versions of the Sportster were powered by a 5-cylinder LeBlond radial engine of 70-85 hp. The third model of the Sportster offered either the Warner Scarab or LeBlond radial engine (renamed as a Ken-Royce engine when Rearwin bought that company).

The Germans targeted the pontoon bridges as soon as the U.S. troops began building them. Directed by forward artillery observers positioned on the steep hills overlooking the river, the Germans continually pounded the engineers, soldiers, and vehicles on the bridges and the roads leading to them. Trucks carrying pneumatic pontoons piggy-backed upon large aluminum heavy pontoons are assembled for transport to Remagen. The 291st Engineer Combat Battalion commanded by David E. Pergrin began constructing at 10:30 am on 9 March a Class 40 M2 steel treadway bridge about down river of the bridge.
|
|
However, Army of the Potomac commander Maj. Gen. Ambrose Burnside prevented the movement, wanting to wait for his army to concentrate and to receive pontoon bridges to make the river crossing. Zook wrote on December 10, "If we had had the pontoons promised when we arrived here we could have the hills on the other side of the river without cost over 50 men—now it will cost at least 10,000 if not more." While waiting for the pontoons to arrive, Zook served as military governor of Falmouth, Virginia.

A pleasure boat with two lengthwise pontoons A pontoon boat is a flattish boat that relies on floats to remain buoyant. These pontoons (also called tubes) contain much reserve buoyancy and allow designers to create massive deck plans fitted with all sorts of accommodations such as expansive lounge areas, stand- up bars, and sun pads. Better tube design has also allowed builders to put ever-increasing amounts of horsepower on the stern. Pontoon boat drafts may be as shallow as eight inches, which reduces risk of running aground and underwater damage.

2 x extra Bridging Vehicles (BV) are required to transport the long span components. Most bridges built in Iraq and Afghanistan have included the LSE General Support Bridge 2 Span Pontoon A General Support Bridge (GSB) 2 span pontoon equipment provides the ability to span larger gaps by using the pontoon as a pier. Two DROPS (support) vehicles equipped with a derrick and hydraulic winch are used to transport the pontoons. The 4 close coupled pontoons are powered by 2 inboard engines, which enables construction and positioning with the minimum of support.

Because of the vulnerability of pontoon bridges, as they rest on water, they have to be designed to withstand not only stresses from traffic but from nature as well. A similar bridge in Washington, the Hood Canal bridge, sank in 1979 after flooding of the pontoons due to winds. Experience from the replacement for that bridge helped engineers better design the pontoons for wave load resistance for the Admiral Clarey bridge. The Admiral Clarey bridge was designed to withstand winds as high as and waves as high as .

In reality only rudders and pontoons were made in Sweden, the rest of the components were secretly manufactured by Caspar in several locations in Germany, to avoid detection by the allies. During 1922 to 1923, the company moved into a former shipyard in Skärsätra on Lidingö since the company had received additional orders from the navy's airforce. The parts for those aircraft was made in Sweden by Svenska Aero, but assembled by TDS. In 1928, the navy ordered four J 4 (Heinkel HD 19) as a fighter with pontoons.

Lord Clive was modified in March 1917 to handle one of the enormous pontoons, in company with Sir John Moore, planned to be used during the Great Landing. Each of the three pontoons was lashed in position between two monitors and could carry a brigade of infantry, an artillery battery and three tanks.Buxton, p. 62 The plan was to land each pontoon between Westende and Middelkerke to exploit the Allied gains made during the Battle of Passchendaele and pocket German troops between the landing and the advancing troops.

The old Faidherbe Bridge Seeing this, the frigate captain Robin, friend of Louis Faidherbe, asked Prince Jérôme Napoléon, Minister of Algeria and the African Colonies, for approval for construction of a floating bridge. Opened on July 2, 1865, the bridge had a total length of (the floating part of the bridge had a length of ) and a width of . The floating part was formed from 40 metal pontoons which supported a wooden deck. Three of these pontoons were specially designed so that it could be created a gap so that large vessels could pass.

A Whale floating roadway leading to a Spud pier at Mulberry A off Omaha Beach Donald Bailey invented the Bailey bridge, which was made up of modular, pre- fabricated steel trusses capable of carrying up to over spans up to . While typically constructed point-to-point over piers, they could be supported by pontoons as well. The Bailey bridge was used for the first time in 1942. The first version put into service was a Bailey Pontoon and Raft with a single- single Bailey bay supported on two pontoons.

The Hobart Bridge was of unique design and construction, and the first of its type anywhere in the world. It was a floating bridge with a lift span, constructed of hollow concrete pontoons, 24 in all, connected together forming a crescent shape curved upstream, and anchored in the middle. The bridge was constructed in 12-pontoon sections which were then towed out into the river and connected to the banks and to each other in the middle. The total volume of concrete used in making these pontoons was .

Offshore drilling in water depth greater than around 520 meters requires that operations be carried out from a floating vessel, since fixed structures are not practical. Initially in the early 1950s monohull ships such as CUSS I were used, but these were found to have significant heave, pitch and yaw motions in large waves, and the industry needed more stable drilling platforms. A semi-submersible obtains most of its buoyancy from ballasted, watertight pontoons located below the ocean surface and wave action. Structural columns connect the pontoons and operating deck.
|
|
External brackets built into the bulkheads transfer the support forces to the pontoons. The girder was built in sections of 21, 36, and 42 meters (69, 118, and 138 ft), which were subsequently welded together into 11 modules with a skew angle of 1.2 to 1.3 degrees. The girder has a constant cross-section throughout the length, except at the anchoring points to the pontoons. The section from the land anchoring to the first pontoon is subject to the most stress, and is made with steel with a higher yield point.

A custom designed twin boom arm was attached to rear of the truck bed and helped unroll and place the heavy inflatable rubber pontoons upon which the bridge was laid. The wheelbase chassis included a front winch and extra-large air- brake tanks that also served to inflate the rubber pontoons before they were placed in the water. A pneumatic float was made of rubberized fabric separated by bulkheads into 12 airtight compartments and inflated with air.U.S. Army Explosives and Demolitions Handbook Department of the Army The pneumatic float consisted of an outer perimeter tube, a floor, and a removable center tube.

The first semisubmersible arrived by accident in 1961. Blue Water Drilling Company owned and operated the four column submersible drilling rig Blue Water Rig No.1 in the Gulf of Mexico for Shell Oil Company. As the pontoons were not sufficiently buoyant to support the weight of the rig and its consumables, it was towed between locations at a draught midway between the top of the pontoons and the underside of the deck. It was observed that the motions at this draught were very small, and Blue Water Drilling and Shell jointly decided that the rig could be operated in the floating mode.

According toHMS > Dotterell there were three great chains resting on 10 pontoons (Schneider, > 115). According to Masterman (chief pharmacist to the Paraguayan forces, > whose medical duties took him to Humaitá) they rested on "lighters" – which > also served as floating prisons – and on rows of piles.

The bridge deck is made of 776 precast concrete sections that are elevated above the concrete pontoons that forms the lower deck which essentially creates "a bridge on top of a bridge". Unlike the older bridge, maintenance vehicles can now access the pontoons from beneath the upper roadway deck without interrupting traffic. According to a project engineer on the site, the deck had to be structurally isolated from the main support structure using a damping system to ensure seismic resistance up to a magnitude 9 earthquake to comply with local building codes. The original deck design called for three support columns but was later revised to two due to aesthetic issues.

The Belgian architect who designed the wall was a refugee in France and supplied his drawings. A replica was built at Merlimont and a detachment of tanks under Major Bingham rehearsed on it, using "shoes" on the tank tracks and special detachable steel ramps carried by the tanks, until they could climb the wall. In experiments on the Thames estuary, the pontoons performed exceptionally well, riding out very bad weather and being easier to manoeuvre than expected, suggesting that they could be used again after the initial assault, to land reinforcements. Night landings were also practised, with wire stretched between buoys to guide the pontoons to within of their landing place.

Engineers realized that jackhammers could not be employed to remove the sidewalks without risking compromising the structural integrity of the entire bridge. As such, a unique process called hydrodemolition was employed, in which powerful jets of water are used to blast away concrete, bit by bit. The water used in this process was temporarily stored in the hollow chambers in the pontoons of the bridge in order to prevent it from contaminating the lake. During a week of rain and strong winds, the watertight doors were not closed and the pontoons filled with water from the storm, in addition to the water from the hydrodemolition.

In May 1945, the new battle damage repair ship conducted shakedown exercises in Chesapeake Bay; then, on 22 May, she departed Norfolk, in company with . She steamed via the Panama Canal and San Pedro, and arrived at San Francisco, on the morning of 1 June. There, she loaded stores and pontoons before getting underway from San Francisco Bay on 28 June. After Ulysses had been at sea for only six hours, the bolts, plates, and turnbuckles holding the pontoons in place began to show signs of bending under the stress of the ocean voyage, and the ship was ordered back to San Francisco, for additional work on the pontoon mounts.

Cutting the cofferdam at Montlake in 1913, draining Lake Washington over the next three months until it was level with Lake Union The Montlake Cut, part of the Lake Washington Ship Canal, connects the lake to Lake Union and ultimately Puget Sound. Concrete floating bridges are employed to span the lake because Lake Washington's depth and muddy bottom prevented the emplacement of the pilings or towers necessary for the construction of a causeway or suspension bridge. The bridges consist of hollow concrete pontoons that float atop the lake, anchored with cables to each other and to weights on the lake bottom. The roadway is constructed atop these concrete pontoons.

As the pontoons were not sufficiently buoyant to support the weight of the rig and its consumables, it was towed between locations at a draught midway between the top of the pontoons and the underside of the deck. It was noticed that the motions at this draught were very small, and Blue Water Drilling and Shell jointly decided to try operating the rig in the floating mode. The concept of an anchored, stable floating deep-sea platform had been designed and tested back in the 1920s by Edward Robert Armstrong for the purpose of operating aircraft with an invention known as the 'seadrome'. The first purpose-built drilling semi-submersible Ocean Driller was launched in 1963.

To land troops swiftly, retaining the benefit from surprise, Bacon designed flat-bottomed craft which could land on beaches. The pontoons were long and wide, specially built and lashed between pairs of monitors. Men, guns, wagons, ambulances, boxcars, motorcars, handcarts, bicycles, Stokes mortar carts and sidecars, plus two male tanks and one female tank, were to be embarked on each monitor. HMS General Wolfe and the other monitors would push the pontoons up the beach, the tanks would drive off pulling sledges full of equipment, climb the sea-walls (an incline of about 30°), surmount a large projecting coping-stone at the top and then haul the rest of their load over the wall.

The amphibious excavator can walk or work in water, because the chassis crawler floats on sealed pontoons. It may swing or even roll over when excavating with no support underneath. It moves using a dual-body boat form buoyancy tank. A reducer drives the crawler chain, allowing free and smooth movement.
|
|
200 pontoons were envisioned, but a unique system of connectors allowed this number to be reduced to 15, which interlock like a jigsaw puzzle. These took one month to assemble. The connectors were designed to be light but robust. Six pylons fixed into the seabed act as the structure's foundation.

|
Catarafts are constructed from the same materials as rafts. They can either be paddled or rowed with oars. Typical catarafts are constructed from two inflatable pontoons on either side of the craft that are bridged by a frame. Oar-propelled catarafts have the occupants sitting on seats mounted on the frame.

The Seirans were to be launched from a compressed-air catapult mounted on the forward deck. A well-trained crew of four men could roll a Seiran out of its hangar on a collapsible catapult carriage, attach the plane's pontoons and have it readied for flight in approximately 7 minutes.Sakaida, p.
|
|
Each pontoon is 360 feet (110 meters) long and 75 feet (23 meters) wide. The pontoons were constructed in Aberdeen by Kiewit Construction. Pontoon construction was plagued by errors and shoddy construction. Reports included workers installing incorrectly sized rebar, installing it in the wrong location, and even having it missing altogether.

The segmented appearance is based on the skeleton of a crab. The shallowness of the water at the bridge site made it impossible to use floating cranes to lift the pre-assembled arches of the bridge into position during construction. The problem was solved by using pontoons and crawler cranes.
|
|
The aircraft was a conventional biplane with equal-span unstaggered wings with small pontoons at their tips. The engine was mounted on a pedestal aft of the cockpit and drove a two-blade pusher propeller. Accommodation for the pilot and single passenger was side by side in an open cockpit.
|
|
Once ashore the pontoons were detachable. The modified tanks were issued to the 18th Panzer Regiment, which was formed in 1940. However, with cancellation of Operation Sealion, the plan to invade England, the tanks were used in the conventional manner by the regiment on the Eastern Front. ;Panzer II Ausf.

The bridge, although damaged, was captured. Howard decided not to force a crossing against increased Confederate opposition. When federal pontoons arrived on July 8, Howard crossed the river and outflanked the Pace's Ferry defenders. This forced them to withdraw; and this permitted Sherman to cross the river, advancing closer to Atlanta.

For activities which require a stable offshore platform, the vessel is then ballasted down so that the pontoons are submerged, and only the buoyant columns pierce the water surface - thus giving the vessel a substantial buoyancy with a small water-plane area. The only concrete semi-submersible in existence is Troll B.

The parallel structures were designed to accommodate three lanes and one pedestrian footwalk each. Between the two floating pontoons made of concrete, each 115 metres long and 22 metres wide, a hydraulically driven rotating middle section made of steel is positioned to allow for undisturbed navigation. To compensate for differences in level as well as for transverse inclinations (heeling) and longitudinal displacements resulting from traffic loads and wave action acting on the ramp, another two rows of 28 transitory elements are installed between the floating pontoons and the transitory ramp on either bank. The structure was formed dynamically distributed energy from waves and pressure from vehicles across the length and breadth of the platform in such a way that they canceled each other out.

Bartini, in collaboration with the Beriev Design Bureau intended to develop the prototype VVA-14 in three phases. The VVA-14M1 was to be an aerodynamics and technology testbed, initially with rigid pontoons on the ends of the central wing section, and later with these replaced by inflatable pontoons. The VVA-14M2 was to be more advanced, with two starting engines to blast into the cavity under the wing to give lift and later with a battery of lift engines to give VTOL capability, and with fly-by-wire flight controls. The VVA-14M3 would see the VTOL vehicle fully equipped with armament and with the Burevestnik computerised anti-submarine warfare (ASW) system, Bor-1 magnetic anomaly detector (MAD) and other operational equipment.

The high-exhaust version of the BRM P56 V8 engine, installed in the rear of BRM P261 In comparison to the older engine, the position of the inlet trumpets and exhaust manifolds had been switched, so that the exhausts exited on the upper surface of the engine, within the cylinder vee, and the inlets protruded above the chassis pontoons on either side of the car. Between the chassis pontoons the engine was covered with a removable, curved panel. Completing the engine cowling was a near-circular gearbox and differential cover at the rear, through which the tail pipes of the exhausts protruded. Shifting the inlets to the outer edges of the car allowed the engine to ingest cooler, denser air, boosting the motor's power output.

The melody is based on a former song of the Spanish military units in the Rif Wars in Northern Morocco in the 1920s. The lyrics may change according to the location of the combat and the units involved. The Gandesa front and the blowing up of pontoons and bridges are related to the passage of the river in the Battle of the Ebro, also mentioned in ¡Ay Carmela!. The Spanish Republican combat engineers were capable of repeatedly repairing the bridges and pontoons in order to allow the loyalist troops to cross the river —at least a few hours every day— despite the steady bombings of the Nazi Condor Legion and the Italian Aviazione Legionaria, as well as the intentional flooding by releasing water from dams upstream.

2d Lt. Herbert A. Dargue, a Coast Artillery officer trained as a pilot at the Philippine Aviation School, was detailed October 18 to fly the plane, based on the beach at San Jose on the south side of Corregidor in Manila Bay. After it was placed back into service in November 1913, it was found that center-of-gravity problems with its front-and-back seating arrangement and heavy pontoons made it incapable of taking off with two persons aboard. Dargue continued one-man operations and with a Coast Artillery officer devised a primitive method of signaling with small parachutes and a Very pistol to indicate misses. S.C. 17 was reconditioned by January 1914 with lighter pontoons that permitted two-man operation.

The bridge can be induced to sway or oscillate in a hazardous manner from the swell, from a storm, a flood or a fast moving load. Ice or floating objects (flotsam) can accumulate on the pontoons, increasing the drag from river current and potentially damaging the bridge. See below for floating pontoon failures and disasters.

Mondragon was part of the brave men who, on the night of April 24, 1547, led the fording of the river "with the sword in the mouth and chest above water", making the enemy take several pontoons in the middle of musket fire. Thanks to the pontoons stolen could build a bridge over the river that allowed the passage of large imperial army who came led by Charles V himself and the Duke of Alba taking by surprise the enemy troops. In April 1559, with the Peace of Cateau-Cambresis he was appointed governor of Damvillers, in the Duchy of Luxembourg and Walloon colonel of the Tercios. As a colonel he served under Sancho d'Avila when they saw the first revolts in Flanders Protestants led by Prince William of Orange.

Others believe that the bypassing of an unreliable magnetic reducer closed a Kingston valve in the forward ballast tank resulting in a delay. Based on other reported issues, there may also have been problems with the air lines supplying the ballast tank. F-4 was stricken from the Naval Vessel Register on 31 August 1915 and was taken from the dry dock in Honolulu Harbor in early September 1915 so the other three F-Class submarines could be dry docked as they had been rammed by the navy supply ship . The F-4 was moved, still hanging from the pontoons to Pearl Harbor and anchored in Magazine Loch until on or about November 25th 1915 when she was disconnected from the pontoons and settled into the mud at the bottom of the Loch.

Beetles were pontoons that supported the Whale piers. They were moored in position using wires attached to "Kite" anchors which were also designed by Allan Beckett. These anchors had such high holding power that very few could be recovered at the end of the War. The Navy was dismissive of Beckett's claims for his anchor's holding ability so Kite anchors were not used for mooring the bombardons.

Boats are moored on buoys, on fixed or floating walkways tied to an anchoring piling by a roller or ring mechanism (floating docks, pontoons). Buoys are cheaper to rent but less convenient than being able to walk from land to boat. Harbor shuttles (water taxis), may transfer people between the shore and boats moored on buoys. The alternative is a tender such as an inflatable boat.

While the desert was crossed with little loss of life, the British were aware of their approach and their attack on the Suez came as no surprise to the defenders. The Ottoman forces were repulsed easily and after two days of fighting, they retreated. Kress von Kressenstein's special pontoons were never used. More than a year passed when the Ottomans tried a second attack on the Suez.

The two officers were appointed on 24 February 1915. The Train grew to 115 men by 12 March and was encamped on Kings Domain, Melbourne. Bracegirdle and Bond had also discovered that no one left in Australian in either the Army or the Navy had any useful knowledge on the subject of bridging trains, they would have to wait for their pontoons and vehicles to be built – meaning a wait of at least six weeks before they would be able to begin training, and that almost all of their unit would need to be taught to ride, on very few horses. The Train embarked upon HMAT A39 Port MacQuarie on 3 June with, according to the Train's Medical Officer, Dr E.W. Morris, 5 officers, 3 warrant officers, 267 Petty Officers and other ranks, 26 reinforcements, 412 horses, 5 6-horse pontoons and tressle waggons, and 8 other vehicles.

Swedish success would depend on how many troops could cross the river without the aid of pontoons before the enemy forces could arrive. Charles as so often led the charge personally, by wading across the water in front of his men. After forming with difficulty on the boggy far bank, the Swedes began to advance through the marsh. Meanwhile, fascines were laid on the river banks to assist the cavalry's crossing.

At 3:00 am Hazen's men boarded the pontoons and quietly rode around Moccasin Point past the Lookout Mountain pickets. Using the river's current for swift movement, an early morning fog helped cover their movements. The landing was to be made at ferry landing and at another gorge downriver. On the morning October 27, there was one company guarding the ferry itself, with five companies nearby in reserve.

The prime mover had limited cargo room, the Engineers wanted a model with a larger body to carry bridge pontoons. The spare tire was moved behind the cab and a ` long bed was placed further back on the chassis. The wheelbase was increased as the rear tandem was moved back for weight distribution. It could tow off-road and on-road like the prime mover, but had a wider turning radius.

Adjusting and supporting the deck with timber blocks was a laborious process requiring much manual work. At each end, a short, ramped length of steel span was provided, carrying the track onto the adjoining trestles. Train speed across the pontoons was limited to 7 miles per hour. Prairie du Chien businessman Lawler took most of the credit for this invention, and made a small fortune through its operation.

Span between Russellville and Dardanelle, Arkansas, at the time the longest pontoon bridge in the world. (Photo c. 1913–1926) The Bergsøysund Bridge uses concrete pontoons When designing a pontoon bridge, the civil engineer must take into consideration the Archimedes' principle: Each pontoon can support a load equal to the mass of the water that it displaces. This load includes the mass of the bridge and the pontoon itself.

Aerial panorama of Wet 'n' Wild and its surrounds Waterfront canal living is a feature of the Gold Coast. Most canal frontage homes have pontoons. The Gold Coast Seaway, between The Spit and South Stradbroke Island, allows vessels direct access to the Pacific Ocean from The Broadwater and many of the city's canal estates. Breakwaters on either side of the Seaway prevent longshore drift and the bar from silting up.

For the final stretch of their journey to the riverbank, the heavy pontoons on sledges were towed by AVREs. Once launched, the ferries were hauled to and fro across the river by RAF Barrage balloon winches.Doherty, pp. 163–164.Pakenham-Walsh, Vol IX, p. 476. For the crossing on the night of 23/24 March, 42nd Assault Rgt was assigned to 15th (Scottish) Division leading XII Corps' attack at Xanten. Having hauled their pontoons through the mud, 42nd Assault Rgt began assembling its rafts at 02.45 on 24 March, and had three operational by 21.00 that night. Two ferry points were used, each with two rafts; 222 Assault Sqn and half of 81 Assault Sqn operated the ferry point codenamed 'Abdullah'. The regiment ran its ferries until the afternoon of 26 March when a Bailey bridge was completed (by 503 Fd Co, see below), during which period it carried 311 tanks and self-propelled guns and a few wheeled vehicles.

As part of the agreement new pontoons and lock gates were to be installed. In 2014 the lock gates at the dock were replaced by contractor Ravestein (Netherlands). The conversion away from gates partially supported by buoyancy lifted the opening restrictions to times of high water, allowing 24hr operations. The floating pontoon berth was sited in the north-east corner of the dock, at the site of the (1966) roll-on/roll-of ramp.

Hockaday had previously assisted engineer Douglas Webber at American Eagle Aircraft Corporation, both of whom later moved to Rearwin Aircraft. Their influence at Rearwin resulted in design elements that were used in the Sportster, thus resembling the Hockaday-designed Flyabout. In 1936, the Sportster was certified to take pontoons at the request of George B. Cluett. This required enlarging the vertical tail after the test aircraft nearly failed to recover from a flat spin.

The next day, 34 coasting vessels sailed into the channel and a bridge was constructed using the vessels as pontoons. Five cables were secured to the opposite bank by attaching each of them to a heavy 18-pounder cannon barrel. When the vessels and cables were in place, a roadway was built of planks. British troops poured across the span and by 27 February the city of Bayonne was completely invested by Hope's corps.

They tried to loosen it by aiming high-pressure streams of water against the mud, but to no avail. The Ministry of Defence soon ran out of money for the operation and gave the job to a private company. They too pumped air into the hull to lift it and pulled wires under the ship to lift it. After ten days, on August 5, 1926, the ship surfaced and floated with the aid of pontoons.

The big drydock also known as Prins Hendrik-dok II would have a lift capacity of 8,000 tons and be suitable for ships of up to 500 feet length. The big drydocks was 438 feet long, 96 feet 6 inches wide and could lift 7,500 tons. It was of the self- docking type made of 6 six connected, but different pontoons. Each of these could be decoupled so it could be repaired and painted.

Material can be transferred to a bench conveyor directly or via a discharge boom or mobile conveyor bridge. Like the BWEs, bucket chain excavators also feature a fixed or rotating superstructure with a counterweight boom that allows the cutting boom a certain degree of verticality. Likewise have a substructure equipped with either a rail or crawler-mounted undercarriage for mobility and transportation. Some BCEs have 'hopping' pontoons similar to those found on walking dragline excavators.

Some Whitstable people had bought the hull for £260. Attempts to raise the Belle on 21 November 1857 were unsuccessful despite successfully raising the stern out of the water with the help of four pontoons. One of the chains around the hull broke during the process, aborting the attempt. The masts disappeared from view in early December, and a green buoy marked wreck was put in place 10 fathoms eastward from the stern.

In August 1983, the wreck of Ocean Ranger was refloated and sunk in deeper waters by the Dutch firm Wijsmuller Salvage. Since its sinking the previous year, concerns over the wreck's position had been made by the federal government. As the Ocean Ranger was situated at an approximate 30 metres below the water, the wreck posed a danger to shipping. The operation saw Ocean Ranger towed upside down with her two pontoons breaking the surface.

Half an hour later, the company reported it had reached the crossing site without encountering any resistance. The Egyptian battalion fighting the paratroopers had focused all their attention on the Israelis at Tirtur, ignoring activity on Akavish. Adan took a risky decision, sending the irreplaceable pontoons down Akavish to the canal. IDF bulldozers cleared the road of wreckage and debris, and the Israelis reached Fort Lakekan before turning northwards, finally reaching the crossing site.

An alternative to the DD was the "T-6 Device", developed by the US Army. Limited numbers of the "T-6 Device" were used by the US Army and Marines during the landings on Okinawa. The "T-6 Device" kit consisted of a structure of box-like, pressed-steel floats (pontoons) mounted on the front, rear and sides of a Sherman. No propellers were fitted – propulsion was provided by the rotation of the tracks.

During Maj. Gen. William Tecumseh Sherman's advance through Georgia in the spring of 1864, the Army of the Cumberland numbered over 60,000 men, and Thomas's staff did the logistics and engineering for Sherman's entire army group, including developing a novel series of Cumberland pontoons. At the Battle of Peachtree Creek (July 20, 1864), Thomas's defense severely damaged Lt. Gen. John B. Hood's army in its first attempt to break the siege of Atlanta.

On February 1, 1911, it received a license to build Wright aircraft from the Wright Brothers, who held several key aeronautical patents. Burgess was charged licensing fees of $1000 per aircraft and $100 per exhibition flight. In 1912 Burgess fitted some of its Wright Model F airplanes with pontoons, contrary to the Wright Company's licensing provisions, which permitted only exact copies of their designs. The license agreement was terminated by mutual consent in January 1914.

Hydrocopters use either skis or wheels on their pontoons to be able to travel on ice, snow or land in addition to traveling on water. This allows them to travel over terrain similar to a hovercraft. Hydrocopters use one system for lift and forward momentum while a hovercraft uses two systems, one for lift and another for forward momentum. Hovercrafts have a constant down thrust which can be undesirable in certain conditions.

Smerch struck an uncharted rock off the Finnish coast on 4 August in shallow water and sank. Using pontoons, she was refloated on 1 September and repaired. Little is known of her service other than she was extensively refitted in 1882 and 1889 which included replacement of much of the plating of her hull bottom. The ship was reclassified as a coast-defense ironclad on 13 February 1892 and subsequently became a training ship.

The cable-stayed section The floating section consists of a steel box girder placed on top of ten floating pontoons. The pontoon section is anchored only at both ends, on the underwater foundation at Kauvaskallen and on Flatøy. It is fastened using flexible plate connections fastened by bolts and cables under tension. These are flexible around the horizontal axis at right angles towards the axis of the bridge, allowing for deformation caused by the tide.

It was different for Claudius' naumachia. The two fleets each consisted of 50 vessels, which corresponds to the number of vessels in each of the two military fleets based at Misenum and at Ravenna. Lake Fucino was large enough that only part of it was needed, surrounded by pontoons, and there was room enough for the vessels to manoeuvre and ram each other. The naumachia of Claudius therefore truly reproduced naval combat.

Underneath the catapult track were four high-pressure air flasks connected in parallel to a piston. The aircraft, mounted atop collapsible carriages via catapult attachment points along their fuselages, would be slung 70–75 feet along the track, though the piston itself only moved between eight and ten feet during operation.Sakaida, p.134 Two sets of pontoons for the Seirans were stored in special watertight compartments located just below the main deck on either side of the catapult track.

The Gannet is an evolution of the Mascato S100 which was designed to comply with the Fédération Aéronautique Internationale microlight rules. It features a cantilever high-wing, a two-seats-in-side-by-side configuration enclosed cockpit, under a forward-hinged bubble canopy, wing-tip pontoons and a single engine in pusher configuration. As a true flying boat, it has no wheeled landing gear. The Gannet is made entirely from carbon fibre, Kevlar and fibreglass composites.

Wharves 1 and 2 comprise two separate piers joined at one end in a 'U' shape with the open arms ending in pontoons, each with one docking station. Pontoon 1 lies upstream of pontoon 2 and CityCats coming downstream berth up at pontoon 1 while those coming upstream berth at pontoon 2. There is no separate passenger waiting area for these wharves. However, tree shaded benches are present along the promenade that runs by the head of the piers.

From the very beginning of the Royal Swedish Navy's submarine era, the issue of Submarine Escape and Rescue has been an integrated part of the submarine system. The first submarine of the Royal Swedish Navy (Hajen, which was delivered in 1904), could be equipped with prefabricated pontoons that were constructed for fulfilling two goals. First, they reduce draft when needed e.g. for passing through the Göta Canal, a channel through Sweden between the east and west coast.

This massive vessel served as an elaborate floating palace for the Emperor. In 39, Caligula performed a spectacular stunt by ordering a temporary floating bridge to be built using ships as pontoons, stretching for over two miles from the resort of Baiae to the neighbouring port of Puteoli.Suetonius, The Lives of Twelve Caesars, Life of Caligula 19. It was said that the bridge was to rival the Persian king Xerxes' pontoon bridge crossing of the Hellespont.

Cozzens, pp. 299-300; Kennedy, pp. 230–231. After Chickamauga, the Army of Tennessee besieged the Union army in Chattanooga, taking up defensive positions on the surrounding hills, especially on Missionary Ridge, which formed the Confederate center, and Lookout Mountain on the Confederate left. Bragg considered a direct attack on the city too costly, and a lack of supplies and pontoons caused him to reject a plan to cross the river and break the Union supply line to Nashville.

The Japanese government kept a close eye on activities in the Philippines for violations of the 1922 treaty. During the typhoon season of 1928, VT Squadron Five which operated Martin torpedo aircraft out of Manila, arrived in Subic Bay on a routine training flight. A typhoon suddenly veered toward Subic Bay and the plane crews had to lay down ramps to haul the seaplanes up on the beach. The pontoons were filled with water and the planes lashed down.

She sailed to the sea off Normandy, detaching the Rhino barges to the beach at 16:15 on 6 June 1944. At 20:10 she received the first group of casualties via DUKWs and returned to Solent, on 7 June. She left Solent, for her second trip to France, on 9 June, anchoring off the Normandy beach at 03:35 on 10 June, moving pontoons ashore and returned to Solent, 11 June, proceeding to Southampton, the next day.

The lido was designed in 1935 by John Wibberley. It was officially opened on 2 October 1935 A victim of declining popularity and neglect, the lido closed in 1992 but a vociferous local campaign led to a renovation, at a cost of £3.4 million, and Grade II Listed Building status in 1998. The facility re-opened to the public in 2005. During refurbishment the three tidal pools, pontoons and diving boards were all removed or filled in.

On 4 September, two additional versions of the Siebel ferry, one powered by Opel Blitz truck engines and one powered by Ford V-8s were tested on the Ems estuary. Using only water screw propulsion, they achieved a cruising speed of , although it was believed this could be raised through efficient propellers. The Siebel ferry pontoons were flat-bottom and square in front. In combination with the vessel's wide cargo deck, this made for an exceptionally stable gun platform.

By far, the most popular tourist activities on the Great Barrier Reef are snorkelling and diving, for which pontoons are often used, and the area is often enclosed by nets. The outer part of the Great Barrier Reef is favoured for such activities, due to water quality. Management of tourism in the Great Barrier Reef is geared towards making tourism ecologically sustainable. A daily fee is levied that goes towards research of the Great Barrier Reef.

Technically, the ferry is a reaction ferry, which is propelled by the current of the water. An overhead cable is suspended from towers anchored on either bank of the river, and a "traveller" is installed on the cable. The ferry is attached to the traveller by a bridle cable. To operate the ferry, rudders are used to ensure that the pontoons are angled into the current, causing the force of the current to move the ferry across the river.

On July 1, 1942, after two months of work, the War Department opened a pontoon bridge located between the Railroad and Highway bridges. It connected Ohio Drive, then Riverside Drive, to US Highway 1. The bridge was constructed of 30 plank covered pontoons with an asphalt coating for the 12 foot-wide floor. A fixed steel span on the Virginia side provided an opening 30 feet wide and 21 feet high for boats to pass under.
|
|
Also in 1943, a barrack for Marines was built, work began on another approach pier, a drydock crane was erected, and several shop buildings were started. In 1944, work started on the pontoons destined to be used in a "temporary" bridge to Terminal Island. The pontoon bridge would not be removed until the opening of the Gerald Desmond Bridge in 1968. The name of this facility was changed to Terminal Island Naval Shipyard on 30 November 1945.

This led to some conflict with Brunel over disruptions to his work, although equally it was encouraged by other contractors as an alternative to the evils of drink. In 1858 Brunel appointed Richardson as the resident engineer of the Bristol and South Wales Union Railway. This work involved railway lines and tunnels, but also two large piers at New Passage and Portskewett. These piers included floating pontoons to cope with the enormous tidal range of the Severn estuary.

Then the only U.S. battleship in commission, Missouri was proceeding seaward on a training mission from Hampton Roads early on 17 January 1950 when she ran aground from Thimble Shoal Light, near Old Point Comfort. She hit shoal water a distance of three ship-lengths from the main channel. Lifted some above waterline, she stuck hard and fast. With the aid of tugboats, pontoons, and a rising tide, she was refloated on 1 February 1950 and repaired.

For sailors, there is a marina and pontoons. The harbour is well protected from the elements by sturdy quays, one of which is topped with a small disused lighthouse. The people of Findochty speak in the Scots dialect of Doric and the accent can be thick and hard to understand for outsiders. In 1901, old animal bones taken to be made into implements, were discovered in a cave found in the cliff near the present bowling green.

Planning of the replacement bridge started in 1997 with a cross-lake study conducted by the state Department of Transportation. The study followed several others in the late 20th century to find solutions to traffic on the SR 520 floating bridge, with most proposals rejected after heavy opposition from communities on both ends of the bridge. The final environmental impact statement for the project was issued in 2011, allowing for construction of the pontoons to begin the following year.

Replacement bridge, to the north of the Rosellini Bridge, under construction in May 2015 Photo of the south side of the bridge in 2015, with construction visible in the background. New Evergreen Point Floating Bridge has been in use since April 2, 2016. The cost of all improvements to SR-520 between I-5 and I-405, including the new bridge, is forecast to be $4.65 billion. The first of 21 longitudinal pontoons were positioned on August 11, 2012.

However, problems arose to delay the operation until the French effected repairs. First, the 4th Division was immobilized by a lack of shoes and had to wait for a new shipment from Lisbon. Next, ample bridging material was supposed to be available at the Portuguese fortress of Elvas, but the number of pontoons proved inadequate to span the Guadiana River. The military engineers improvised a bridge, but it was immediately washed out by a flood on 4 April.

Rather than demolishing the hangar, the University chose to repurpose the building as the ASUW Shell House. The Shell House's convenient waterfront location was perfect for storing and transporting the crew team's rowing shells to both competition and practice on Lake Washington. The Shell House was also partially transformed into a workshop for George Yeoman Pocock, the renowned boatbuilder who previously built pontoons for the Boeing company. Pocock constructed racing shells at this location until 1949.

It was intended to be used to build floating bridge pontoons for the Hood Canal Bridge replacement. The graving yard project, which was being constructed by the Washington state government, encountered the large village site of Tse- whit-zen, including its cemetery. More than three hundred bodies were exhumed and removed from the site before Washington Governor Gary Locke intervened and permanently halted the construction in December 2004. The three hundred remains were reburied by the Lower Elwha.

They ultimately settled on a plan to make the ship's hull airtight and raise it using compressed air and pontoons. This required that the ship's coal, ammunition, and gun turrets be removed or cut loose, respectively, by divers to reduce her weight. A further complication was that the largest drydock in Taranto had a maximum depth of only and the upside-down Leonardo da Vinci drew . This meant that her funnels had to be cut off as well.

|
The front hull mounted a Type 1 47 mm tank gun and a Type 97 7.7 mm machine gun. The chassis was based on the Type 5 Chi-Ri medium tank and the suspension, pontoons and propulsion system were substantially the same as the Type 3 Ka-Chi. According to one source, a prototype was completed by the end of the war. According to another source, a prototype was not completed by the end of the war.

Situated about 1 mile to the north of where the River Shannon enters Lough Derg, Portumna Bridge must be opened to allow craft with more than 4 ft of air draft to pass by. The bridge is opened only at fixed times. There are quays both north and south of the bridge where craft may tie up while they wait for the bridge to open and there are mid-stream pontoons both upstream and downstream of the bridge.

In the early 19th century, Mahmud II (1808–1839) had a bridge built a bit further up the waterway, between Azapkapı and Unkapanı. This bridge, known as the Hayratiye (Benefaction in English), was opened on September 3, 1836. The project was carried out by Deputy Lord High Admiral Fevzi Ahmet Paşa using the workers and facilities of the naval arsenal. According to the History of Lutfi, this bridge was built on linked pontoons and was around long.

Kiel Week is held annually in the last week in June, and opens officially on the preceding Saturday with the official Glaser, followed by the Holstenbummel. The "Soundcheck" is on the Friday before the official opening; it is a music festival across all the stages within the city. Kiel Week, ends with a large fireworks display at 11 p.m. on Sunday, fired from pontoons or the quays at the Howaldtswerke, visible all across the Bay of Kiel.

One landed approximately off the starboard side near an ammunition pontoon; the other landed some off the port quarter. A large rocket missed the ship, landing harmlessly away. Vernon County manned her battle stations and returned the fire with 46 rounds of 3-inch (76.2-millimeter) gunfire. On 23 February 1969, PAVN/VC automatic weapons fire came in the direction of Vernon County, most rounds concentrated on one of the pontoons alongside or at the bridge.

The ferry is attached to the traveller by a bridle cable. To operate the ferry, rudders are used to ensure that the pontoons are angled into the current, causing the force of the current to move the ferry across the river. The ferry operates under contract to the British Columbia Ministry of Transportation, is free of tolls, and runs on demand between 0700 and 1820. It carries a maximum of 2 cars and 12 passengers at a time.

Landungsbrücken building The first pier here was built in 1839 at what was then the edge of the harbour. It served as a terminal for steamships, which could be relatively easily filled with coal here. The pier ensured a sufficient security distance from the city, since these ships were fueled by coal which presented a fire risk. The current piers built in 1907 consist of floating pontoons, which are accessible from land by ten movable bridges.

At 2:00 pm, Letort's Guard cavalry left Méry with the newly-captured pontoon train. During the afternoon, they became embroiled with the Crownprince's cavalry under Peter Petrovich Pahlen, Prince Adam of Württemberg and Johann Nepomuk von Nostitz-Rieneck. Letort's horsemen inflicted 100 casualties on their foes while sustaining the loss of 120 men and three pontoons. Though assisted by Jean Nicolas Curely's brigade from Sigismond Frédéric de Berckheim's cavalry division, the French were driven back to Méry.

In recent years the beach has been the focal point for the new year celebrations in the town. A temporary concert stage is erected on the Largo 25 de Abril and concerts are held to celebrate the new year. In the past the celebration has seen international bands appearing such as British reggae/pop band UB40 in 2009. The celebrations cumulate with a firework display held just of the beach on boats and pontoons just of the shoreline.

When these proved to difficult to move and to have too deep of a draft, barges formed of Navy P-1 pontoons were the workable solution.Forbes & Williams 1987 p.101 M101A1, and later M102 howitzers were mounted onto a baseplate welded to the barge deck, allowing the howitzer to be traversed 360 degrees. A complete battery of riverine 105mm artillery consisted of three howitzer barges, and five LCM-8s for support staff such as the Fire Direction Center.

A new design was needed, or as it turned out an older design made new. In the past wood ships hulls with no interior were used to drydock smaller ship that could fit into the drydock ship. This design, but with a steel ship hull was needed. The repair dock would have new modern steel ballast pontoons tanks that could be flooded with water to submerge the dock or pumped dry to raise a ship in need of repair.

Motoryacht ARTEFACT Nobiskrug was founded in 1905 by Otto Storck. The company changed to a limited liability company (GmbH), November 12, 1908, and a canal expansion work brought a steady stream of waterway construction vessels to the shipyard for repairs and refits. By the start of World War I, the shipyard had built a total of 70 vessels, mainly pontoons, barges and lighters. During the war, the company built a number of auxiliary ships for the Kaiserliche Marine and started building minesweepers.
|
|
Prior to construction, extensive testing of the pontoons' strength and stability occurred over a nine-month period in 1938. An experimental barge approximating the proposed bridge's configuration was anchored in the lake, and the most powerful tug on the West Coast was hired to put it to the test. Captain Guchee took Arthur Foss at full speed around and around the test barge, generating four-foot waves and simulating lake conditions in an wind. Engineers and technicians were on hand to take readings.

Low crops in the unfenced countryside offered no natural concealment to the Allies. Deep, narrow paths cut into the escarpment at right angles, exposing any infiltrators to extreme hazard. The forces on the northern plateau commanded a wide field of fire. In dense fog on the night of 13 September, most of the British Expeditionary Force (BEF) crossed the Aisne on pontoons or partially demolished bridges, landing at Bourg-et-Comin on the right and at Venizel on the left.

Partridge, p. 630. Early in 1864, the commander of the Army of the Cumberland, Major General George H. Thomas, was seeking a light-weight, easy-to-haul and erect pontoon bridge to move his troops across unfordable rivers and streams. Knowing the limitations of the two systems used by the armies in the Western Theater, he had folding pontoons developed. A similar idea had been instigated by his predecessor William S. Rosecrans earlier in the war, but had not been adopted.

There is also the long pontoon bridge called the Bergsøysund Bridge which goes between the islands of Bergsøya and Aspøya, which is the only bridge of its kind where nothing but the ends are anchored to solid rock. The bridge is supported by 7 pontoons, floating on a deep fjord. The long underwater Freifjord Tunnel goes under the Freifjorden. It is reaches a depth of below sea level at its deepest point, though the bottom of the tunnel is in solid rock.

Mokes retain their cult status, and there are many enthusiastic restorers. The Moke's construction is simple. The body mainly consists of two box-section "pontoons" or "sideboxes" running between the front and rear wheels, and include (non-hollow) extensions of that from the back of the car all the way up to the front. These are connected by the floor pan, the firewall and a sturdy lateral torque box that runs under the front seats and stiffens the body in torsion.

2698 and the name was in use by the late 1890s. Power is collected from the rider via a crank with pedals, as on a bicycle, and delivered to the water or the air via a propeller. Seating may be upright or recumbent, and multiple riders may be accommodated in tandem or side-by-side. Buoyancy is provided by two or more pontoons or a single surfboard, and some have hydrofoils that can lift the flotation devices out of the water.

Wong Tsu, a MIT graduate who was hired by Boeing in May, 1916, also contributed to the design, specifically lending his expertise in analysis of wind tunnel data. Westervelt, who had been reassigned to the East Coast in December 1915, consulted heavily on the design. A total of 56 C-type trainers were built; 55 used twin pontoons. The Model C-1F had a single main pontoon and small auxiliary floats under each wing and was powered by a Curtiss OX-5 engine.

388, Brig. Gen. Thomas J. Wood, U. S. Army, commanding Third Division. Not seeing a suitable opportunity to attack the strong Confederate positions across the Chattahoochee, Howard ordered his corps into camp on high ground facing the river and awaited the arrival of Federal pontoons. July 10, Stanley's and Wood's divisions moved to near the mouth of Sope Creek, in support of General John Schofield, who had crossed the river at that point (north of Pace's Ferry) and outflanked the Confederates.

Dredging operations in the Potomac River in 1930. Note the floating pontoons which outline the soon-to-be-completed land which will define the Pentagon Lagoon, and the unfinished central bascule span in Arlington Memorial Bridge. In 1922, Congress authorized the Arlington Memorial Bridge Commission (AMBC) to hold a design competition for the proposed Arlington Memorial Bridge. It awarded the design commission to the firm if McKim, Mead and White, which appointed architect William Mitchell Kendall to be the lead designer.

Two swing bridges, Hayhurst Bridge built in 1898, and Town Bridge built in 1899, cross the Weaver at Northwich. The bridges were the first two electrically powered swing bridges in Great Britain and were built on floating pontoons to counteract the mine subsidence. They were designed by Colonel John Saner. The Floatel Northwich was moored on the Weaver near the confluence of the two rivers, but was closed when the owners, The Real Hotel Company plc, went into administration in January 2009.

The majority of the pre-cast girders and deck panels were constructed in Tacoma, Washington and shipped by barge. The three concrete pontoons for the floating moveable span were also constructed in Tacoma by Concrete Technology Corporation in a graving dock and floated to Ford Island by barge in three shipments. They are long, wide, and tall, and contain 21 water-tight air-filled cells with leak detectors to provide buoyancy. The three sections were assembled at the site using large steel bolts.

Kyle of Lochalsh The village is the transport and shopping centre for the area as well as having a harbour and marina with pontoons for maritime visitors. The Plock offers a local woodland hike and viewpoint over the peninsula. The surrounding scenery and wildlife are regarded as attractions of the village, as is the slow pace of life. Crofting as well as more recent crofting pursuits like salmon farming are some of the activities taking place in Kyle of Lochalsh.

|
The structural engineers and the contractor decided the design was faulty. A new contractor was hired and the design modified. It was decided to use a large rubber dam between each of the two pontoons as they were attached, clean the concrete surfaces of all marine growth, epoxy, and tension them with a number of cables welded to a variety of attachment points. This system seemed to work from when the bridge opened in 1961 until the disaster of 1979.

Access on foot along the Limehouse Cut was difficult in the area below the Blackwall Tunnel approach road, but was made easier as a result of an innovative scheme to create a floating towpath. This was opened in July 2003 and consisted of 60 floating pontoons, creating a walkway complete with green glowing edges. The Cut is part of the Lee Navigation and is administered by the Canal & River Trust. It was built for sailing barges, and can accommodate vessels which are .

At this point, the righting force will disappear, replaced by a turning moment in the opposite direction. This can capsize the vessel at the point at which one pontoon is completely submerged. When using twin lateral pontoons, each pontoon should have enough buoyancy to bear the load of the entire vessel on its own. If the vessel is so heavy that either pontoon is mostly submerged when no lateral force is applied, it will be vulnerable to the pontoon effect.
|
|
The replacement operation was expected to be finished in 12 hours. It was an arrangement suited to the tropical circumstances, which required each pontoon to be maintained once a year. The reserve pontoon made it possible to delay actual maintenance till it could be lifted together with a ship which did not require the whole length of the dock. The main pipe which was used for emptying the pontoons was placed in one of the sides, so it always stayed intact.

Rowing is one of the sports available to F5 competitors. Currently, people with a complete spinal cord injury at T12 level or incomplete at T10 compete in AS. This class is for people who use their arms and shoulders to row. They have decreased balance while rowing. They row largely using their arms and shoulders to gain propulsion in the water They are required to use a chest strap, a knee strap, pontoons on their boat and short oars to prevent overlap.

It appeared in waters off the Netherlands and France at much the same date and here it was growing on Sargassum muticum, species of Fucus and Laminaria, sponges, solitary tunicates, shellfish and directly on the underside of pontoons. On the western coast of North America it has been found in Humboldt Bay and San Diego Bay, California. It is probable that it was dispersed as a fouling organism on the hull of ships or accidentally as a result of aquacultural operations.

However, weather conditions delayed the movement, so Grant decided to move ahead with the Brown's Ferry operation even before Hooker could arrive. Smith's plan for the assault on Brown's Ferry was to send most of one brigade (Brig. Gen. William B. Hazen's) traveling stealthily downriver on pontoons and a raft at night to capture the gap and hills on the west bank of the Tennessee while a second brigade (Brig. Gen. John B. Turchin's) marched across Moccasin Point in support.

Sikorsky fitted utility floats (also called pontoons) to the VS-300 and performed a water landing and takeoff on 17 April 1941, making it the first practical amphibious helicopter."Timeline". Sikorsky.com. Retrieved: 22 September 2009. On 6 May 1941, the VS-300 beat the world endurance record held by the Focke-Wulf Fw 61, by staying aloft for 1 hour 32 minutes and 26.1 seconds. The final variant of the VS-300 was powered by a 150 hp Franklin engine.

Reflecting this, Barassi has lent his name to the Barassi International Australian Football Youth Tournament. He is a supporter of Australia becoming a republic. More recently, he was one of the last runners in the Queen's Baton Relay for the 2006 Commonwealth Games, being held in Melbourne, Australia between 15 and 26 March. His section of the relay, run on 15 March, involved taking the Baton from a series of pontoons in the middle of the Yarra River onto shore.

These piers were the floating roadways that connected the "Spud" pier heads to the land. These pier heads or landing wharves, at which ships were unloaded each consisted of a pontoon with four legs that rested on the sea bed to anchor the pontoon, yet allowed it to float up and down freely with the tide. "Beetles" were pontoons that supported the "Whale" piers. They were moored in position using wires attached to "Kite" anchors which were also designed by Allan Beckett.

From there, he proceeded to Posen, where he captured another magazine on 17 September. Meanwhile, the Russians had besieged Kolberg for the third time, and had thwarted all Prussian relief efforts. In an action at Landsberg, with the principal bridge over the Warta river destroyed, Platen's troops crossed the river with the help of pontoons and rafts. At Körlin, on 30 September, he was able to recapture from the Russians an intact bridge over the Parsęta river, taking 200 prisoners in the action.

However, as the guns were unlimbered in park, not for action, the Royals were unable to use them against the French. The Duc de Laval and his battalion of the Crillon brigade then came up behind the pontoons and wagons engaging the Royal Scots soon to be followed by two more battalions led by Le Marquis de Crillon . The nature of the terrain was unfavorable to cavalry and the allied cavalry was unable to aid the Royals.Letter Lieutenant General Moltke to HRH Cumberland 9, July 1745.

"Builders of Concrete Ships: WWII Construction Record" The U.S. government also contracted with two companies in California for the construction of concrete barge ships. Barge ships were large vessels that lacked engines to propel them. Instead, they were towed by tugs. In Europe, ferro cement barges (FCBs) played a crucial role in World War II operations, particularly in the D-Day Normandy landings, where they were used as part of the Mulberry harbour defenses, for fuel and munitions transportation, as blockships, and as floating pontoons.

A Mouthful of Earth () is the only play written by the West German author and Nobel prizewinner Heinrich Böll. Set several hundred years in the future, it concerns a dystopian society living on pontoons above a flooded earth and surviving by scavenging the oceans and processing vestiges of soil. A tyrannical caste system holds sway over society, prohibiting all pleasures and cultural activities. Divers explore the waters and discover relics of the 20th century, leading to surmise and commentary about how life was lived at that time.

Open water swimming events require different tactics and showcase several different racing strategies that are more common to competitive cycling, marathon running and water polo than traditional pool swimming. It is one of the few Olympic sports where the athlete's coaches play a critical role during the actual event. The coaches have four opportunities to provide drinks to their athletes as the athletes swim by floating pontoons in the course. If the coach falls in the water, his or her athlete is immediately disqualified.

The vessel is essentially a large platform supported by eight columns (four on each side), with one pontoon per side. Typical SSCVs use larger columns under the cranes to provide support, which can lead to severe pitching in rough seas; SSCV Sleipnir uses columns that are symmetrical fore and aft for calmer motions under higher sea states. The columns are rounded to reduce wave interactions, and the pontoons are streamlined to reduce drag. The ship's ballast tanks and LNG storage are contained within the eight columns.

The bridge in 1910-1915 The bridge in 1914 The bridge was first proposed in 1910 by the Sanitation Commission of Santos, led by Francisco Saturnino de Brito, to support a sewage pipeline from Santos and São Vicente to the Atlantic Ocean at the Itaipu point in Praia Grande. Detailed plans were subsequently commissioned, led by Miguel Presgrave, with the Trajano and Medeiros & Cia companies. The project for the bridge was developed by August Kloenne. The pontoons for the bridge were installed in 1911.

While the CityCat and ferry fleet escaped damage by mooring downstream at the Rivergate Marina or Manly harbour, much of the infrastructure was damaged or destroyed by the floods, causing services to be cancelled indefinitely. Partial CityCat and CityFerry services recommenced on 14 February 2011, using fifteen repaired wharves. Six of the remaining wharves opened using rescued and repaired pontoons on 18 April 2011. In 2010, Transfield sold its 50% share in TransdevTSL, and all TransdevTSL operations including Brisbane Ferries became 100% Transdev owned.

On 8 May, a floating crane was brought in from Danzig; the main guns, some of the turret armor, and the bow and citadel armor were all removed. The ship was lightened by —more than a third of her normal displacement—and with the aid of pontoons, eventually refloated by 9 July. The ship was towed to Mariehamn where some limited repairs were effected. On 24 July the ship departed for Kiel with the assistance of two tug boats; she arrived there three days later.

Shortly thereafter, several people expanded on experimentation of rubber coated fabrics. In 1839 the Duke of Wellington tested the first inflatable pontoons. In 1840, the English scientist Thomas Hancock designed inflatable craft using his new methods of rubber vulcanization and described his achievements in The Origin and Progress of India Rubber Manufacture in England published a few years later. alt=Two small dinghies In 1844 - 1845, British naval officer Lieutenant Peter Halkett developed two types of inflatable boats intended for use by Arctic explorers.

The Hood Canal Bridge suffered catastrophic failure in 1979 during the February 13 windstorm. During the night, the bridge had withstood sustained winds of up to and gusts estimated at , and finally succumbed at about 7:30 a.m. on Tuesday, The western drawspan and the pontoons of the western half had broken loose and sunk, despite the drawspan being opened to relieve lateral pressure. At the time of the failure, the bridge had been closed to highway traffic and the tower crew had evacuated; no casualties resulted.

The fact that the contractor Skanska's climate compensation for the freight also receives criticism, because it does not reduce emissions here and now.Stockholm Direkt: Här byggs Slussens kritiserade guldbro i Kina, publicerad 2 oktober 2019. On site in Stockholm, the ship will be lowered and the bridge, which is located on pontoons, will be towed in place between Stadsgårdsleden and Skeppsbron. Once in place, it will be mounted on prepared bridge pillars and is expected to open for traffic at the end of August 2020.

The prototype flew in this form in July 1965, and it was exhibited and flown at the 1966 Hannover Air Show. The Skytrac 1 was followed by a second machine with pontoons and a V-tail at the end of a boom for improved directional control. The third prototype had three seats in a more conventional cabin structure, and was fitted with spray bars and chemical tanks for demonstration of the type's potential as an agricultural machine. Certification of the design was achieved in 1969.

On 13 October 193 Bty helped drive off a 'small but well organised' German attack with their A/T guns and Bren guns, while 241 Bty contributed fire from 2-inch mortars. The regiment also practised assault river crossings, using stormboats to ferry Jeep-towed 6-pdrs and improvised pontoons with outboard motors to carry 17-pdrs and Quad tractors.61 A/T Rgt war diary at RA Netherlands. On 23 October the regiment took part in Operation Colin, a divisional attack on Schijndel.

During the lull, Wellington ordered John Hope's corps to begin the isolation of Bayonne. Since Adour is wide with a tidal rise of below Bayonne, Soult never suspected the Allies would cross there and did not guard the north bank. Facing an Allied offensive that required crossing rivers, the French marshal believed that his foes would not have enough boats or pontoons to bridge the river. Hope sent eight companies from the 1st Division across the Adour on 23 February to form a bridgehead.

Approved by voters in 2008, the line will connect Overlake Transit Center at Northeast 40th Street and Overlake Village station at 152nd Avenue Northeast to Seattle and Downtown Bellevue, crossing Lake Washington on the I-90 floating bridge. In 2024, the line will be extended along SR 520 to Downtown Redmond, using funding from the Sound Transit 3 program approved by voters in 2016. The rebuilt floating bridge was also designed to accommodate a future light rail extension, requiring supplemental pontoons and new approaches.

A contract for the remainder of the building was awarded to Messrs Hudson and Male. The first span and centre pier under construction in 1854, seen from Saltash Mare's first task had been to establish an erecting yard on the Devon shore with a jetty and workshops. He then proceeded to construct a iron cylinder tall which was to form the work base for the construction of the central pier. This was launched in May 1854 and moored in the centre of the river between four pontoons.

The second siege would be more successful for the Williamites, than the first a year earlier. The besiegers began to dig trenches on 27 August, and on 3 September the siege batteries opened fire. The artillery fire made a great deal of damage to the city defences, but the high water made an assault difficult. A large force under the Duke of Würtemberg therefore crossed the Shannon on pontoons on 22 September, drove away the Jacobite cavalry outside the city and advanced towards it from the west.

In June–July 1703, Halil Pasha led a three-pronged attack against western Georgia. The troops under his direct command crossed the Çoruh River on pontoons and invaded Guria, while the contingent under his second-in-command joined by the troops of Ishak Pasha of Çildir fought their way through the Zekari Pass into Imereti. The third force was landed by the Ottoman navy in Mingrelia. Facing the invasion, Imereti's ruler Abashidze had secured the loyalty of Gurieli and Dadiani as well as most Imeretian nobles.

In some cases, however, only the reactor compartment is removed, and pontoons attached to keep it afloat. A third method involves filling the reactor compartment with polystyrene for buoyancy. "Reactor compartments from Polyarny and other shipyards at the Kola Peninsula and in Severodvinsk, Arkhangelsk county, are towed to Sayda Bay". On 10 August 1985, control rods were incorrectly removed from a Victor class submarine during defueling at Chazma Bay naval yard outside Vladivostok, resulting in an explosion, the "release of large amounts of radioactivity", and ten deaths.

Uganda Army officers concentrated on looting and ignored intelligence reports of Tanzanian plans, and thus were caught unprepared when the TPDF initiated Operation Chakaza. Most Ugandan soldiers fled in the face of artillery bombardment, and Amin soon thereafter declared that he was unconditionally withdrawing the Uganda Army from Kagera, a claim which was bitterly contested by Tanzania. Tanzanian troops used pontoons and a Bailey bridge to move heavy equipment across the river and probed the area. By January 1979 the TPDF had re-secured the Kagera Salient.

Due to the demanding expedition ahead, spare parts, including 15 extra Liberty L-12 engines, 14 extra sets of pontoons, and enough replacement airframe parts for two more aircraft were chosen. These were sent to airports along the route. The last of these aircraft was delivered to the U.S. Army on 11 March 1924. The four aircraft left Seattle, Washington, on 6 April 1924, flying west, and returned there on 28 September to great acclaim, although one plane was forced down over the Atlantic and sank.

It featured three tonnes of pyrotechnics and lasted for 35 minutes. Skyfire Mark V, on 7 March 1993, featured 436 separate shots, coordinated to music by artists including Madonna, Midnight Oil and Prince. The show used more than five tonnes of fireworks, launched from 10 pontoons floating in the middle of the lake. In 1994, Skyfire was held on 13 March and featured six tonnes of aerial and water fireworks worth almost $250,000. Skyfire X, on 8 March 1998, attracted an estimated 120,000 visitors.

Already, fifteen pontoons were on the river, nearly spanning it, and five more were amply sufficient. Burnside began at once to bring up his artillery, which had the effect of making a perfect mortar bed. For a considerable area around the ford all day the men worked in the rain but to little purpose. Quite a number of cannon were advanced near the ford, but the 22nd only added to the storm, and the artillery, caissons and even wagons were swamped in the mud.

An overhead cable is suspended from towers anchored on either bank of the river, and a "traveller" is installed on the cable. The ferry is attached to the traveller by a bridle cable. To operate the ferry, rudders are used to ensure that the pontoons are angled into the current, causing the force of the current to move the ferry across the river. The ferry operates under contract to the British Columbia Ministry of Transportation, is free of tolls, and runs on demand between 0700 and 1820.

The ferry is attached to the traveller by a bridle cable. To operate the ferry, either the right or left bridle cable is tightened to angle the pontoons into the current, causing the force of the current to move the ferry across the river. The ferry operates under contract to the British Columbia Ministry of Transportation, is free of tolls, and runs on demand between 0645 and 2315with some gaps in service. It carries a maximum of 2 cars and 12 passengers at a time.

Standing the boat upright against a wall allows the water to fall down and out of the boat taking with it these unwanted particles. The boat is then returned to the trailer and the four pontoons are allowed to semi-deflate, to prevent over-stretching of the seams and rubber. The driver will fill in a checklist and report any faults, problems or issues to the club mechanic before storing the craft and motor. He will also report weather conditions and rescues performed for the day.

Hydropower turbines could be integrated into the flood protection barrier. The proposed hydropower array in the Estuary would be 5 kilometres long and 500 metres wide and would harness tidal flows to produce energy with zero carbon emissions. The tidal generation units can sit either on the estuary bed or on floating pontoons. Their proposed location is north of the Estuary Airport and to the south of the Yantlet shipping channel, the main container freight route to Tilbury Docks and the new London Gateway port.

When the NPWS assumed management of Nielsen Park in 1968 they set about making the Park more open and focused on both public recreation and protection of the natural environment. Fencing on the beach was removed, free access was given to the swimming enclosure and the Dressing Pavilion, car parking was banned and two picnic shelters were removed. The wharf was demolished in 1979 along with swimming platforms, pontoons and a diving tower. Women's change sheds near the wharf were removed as were fireplaces at Vaucluse Point.

The halves were then floated out from the dry dock and mated. During the mating operation the halves were supported by temporary pontoons. The hull mating was complete in early 1987 and the two cranes built by Officine Meccaniche Reggiane under subcontract to American Hoist & Derrick Company (Amhoist) were installed in sections by the Saipem crane vessel Castoro Otto in April of that year. The sea trials, which took two months, started in September, and on 15 December the vessel was handed over to Micoperi.

In a different passage he says that there was > no donkey-engine to tighten it when it sagged following destruction of the > intermediate floating supports: Burton, 332. This was so provided an enemy destroyed the chain's intermediate floating supports; for as explained by Thompson, the chains were > supported on a number of canoes, and on three pontoons.According to Burton > they were supported by three chatas (barges): Burton, 332. According toHMS > Dotterell there were three great chains resting on 10 pontoons (Schneider, > 1902, II, 115).

Artist impression of a floating residence Very Large Floating Structures (VLFS) or Seasteads are artificially man-made pontoons, designed to float on the surface of the ocean or sea to house permanent residents. They have a large surface area and are designed to not be bound to a certain government but instead form their own community through clusters of floating structures . This type of technology has only be theorised and is yet to be developed, however a variety of companies have investment project plans underway.

It was realized that extraction of water from the aquifer was the cause. The sinking has slowed markedly since artesian wells were banned in the 1960s. However, the city is still threatened by more frequent low-level floods—the Acqua alta, that rise to a height of several centimetres over its quays—regularly following certain tides. In many old houses, staircases once used to unload goods are now flooded, rendering the former ground floor uninhabitable. Studies indicate that the city continues sinking at a relatively slow rate of 1–2mm per annum; therefore, the state of alert has not been revoked. In May 2003, Italian Prime Minister Silvio Berlusconi inaugurated the MOSE Project (Modulo Sperimentale Elettromeccanico), an experimental model for evaluating the performance of hollow floatable gates; the idea is to fix a series of 78 hollow pontoons to the sea bed across the three entrances to the lagoon. When tides are predicted to rise above 110 cm, the pontoons will be filled with air, causing them to float and block the incoming water from the Adriatic Sea. This engineering work was due to be completed by 2018.

Upon reaching the torpedo room, they heard answering hammer blows from inside the boat. In 1923 the only way the salvage crew could get the men out of the submarine was to lift it physically from the mud using cranes or pontoons. One of the largest crane barges in the world, Ajax, built specifically for handling the gates of the canal locks, was in the Canal Zone. However, there had been a landslide at the famous Gaillard Cut and Ajax was on the other side of the slide, assisting in clearing the Canal.

There were about twenty small battalion guns and twenty pontoons in a camp being established on and around the road that ran between the town of Aalst and Ghent. Parts of the Normandie brigade, some two battalions, were dispersed in various posts along the Scheldt and the road to Ghent as was the some of Crillon. Du Chayla sent his light troops, the Grassins, towards Aalst to reconnoitre. Moltke had orders from Cumberland to throw as many troops as possible from Aalst into Ghent to reinforce the garrison.

A lesser-known part of the aircraft ferrying mission for ATC pilots was search and rescue for Ferrying Command pilots and crews who were forced down in the remote wilderness. The ATC Alaska Wing was equipped with a number of single-engine C-64 "Norseman" light transports, which were equipped alternatively with pontoons, skis and wheels, depending the season. The C-64s were used to resupply stations along the Canadian pipeline as well as for search and rescue work. ATC also developed two transport routes to Alaska during the war to support Eleventh Air Force.

The latter bridge, built by the city of Plasencia under the reign of Emperor Charles V in the 16th Century and known by the local people as the Albalat Bridge, was partially destroyed by the Spanish on 14 March 1809, to prevent its use by the French. The Portuguese under Colonel Mayne destroyed the bridge at Alcantara on 14 May 1809, for the same reason. The French built a pontoon bridge in the autumn of 1809, just west of the Albalat bridge. It was about 200 metres long and built with heavy pontoons.

In anticipation of receiving those funds, Admiral Gennady Suchkov, Commander of the Northern Fleet, decided to tow all the 16 laid up submarines from Gremikha to shipyards where they would be dismantled. K-159 was the 13th hull to be towed. Because K-159s hull was rusted through in so many places, it was kept afloat by spot-welding large empty tanks to her sides as pontoons. Those tanks, however, were manufactured in the 1940s, were not air-tight, and were no better maintained than the submarine's hull.

Coventry Climax were developing a flat-16 engine, the FWMW, as a way of increasing the power from a 1.5 litre engine. To accommodate this engine, Lotus 33 chassis R12 was modified by cutting off the engine pontoons behind the cockpit, as the FWMW was intended to be mounted in a tubular space frame. This project was allocated type number 39. Unfortunately, the FWMW was plagued with development problems and, with a new 3-litre limit for F1 announced for 1966, development was halted, as were plans for a 3-litre version.

The three gunboats then continued towards Manzanillo, where they were spotted by a squadron of Spanish vessels which consisted of the gunboats Guantánamo, Estrella and Delgado Parejo, each one crewed by 19 sailors and officers, plus three armed pontoons.Rodríguez González, p. 119 The pontoons were Guardián, crewed by four gunners manning an old Parrott gun, Cuba Española, an old wooden gunboat armed with a Parrott gun and crewed by seven men, and an old sailboat used as a barracks ship. There were also many commercial vessels in port.

Salvage and towing tests were conducted from 10 – 25 August. Moored on 29 September to allow pontoons to be fixed to her sides, U-1105 underwent another series of salvage and towing tests until 18 November, when she was sunk off Point No Point Light and buoys were left to mark the spot. In the summer of 1949 U-1105 was raised again and towed into the Potomac River and anchored off Piney Point, Maryland for preparations for her final demolition. On 19 September 1949, a MK.6 depth charge was detonated from U-1105.

Situated between the pontoons with no deck underneath, Alvin hit the water and rapidly began to sink. The three crew members managed to escape, but Alvin flooded and sank in of water in the Atlantic Ocean at approximately , about 88 nautical miles (101 miles; 163 km) south of Nantucket Island.Anonymous, SALVOPS 69, Washington, D.C.:Department of the Navy Naval Ship Systes Command, 1969, pp. 1–18. Severe weather prevented the recovery of Alvin throughout late 1968, but it was photographed on the bottom in June 1969 by a sled towed by USS Mizar.

The race begins at the downstream end of Temple Island, where the crews attach to a pair of pontoons. The race umpire will then call out the names of the two crews and start them when they are both straight and ready. Each crew is assigned to row on either the 'Bucks' (Buckinghamshire) or 'Berks' (Berkshire) side of the race course. The coxswains or steersmen are expected to keep their crew on the allocated side of the course at all times during the race, else they risk disqualification.

Using only the ship's aircraft engines, it attained a maximum speed of . In contrast to the truck engines in the pontoons, the aero engines were directly controlled by the helmsman via throttles in the wheelhouse, allowing him to vary each engine's RPM. This greatly improved manoeuvrability, but the aircraft engines were noisy, prevented voice communication on deck, and consumed large amounts of fuel. For Sea Lion, it was decided to use them only for the run-up onto the invasion beaches or as a back-up in the event the water screws were damaged.

The Type 2 Ka-Mi was based on the army's Type 95 Ha-Go light tank, but with an all-welded hull with rubber seals in place of the riveted armor. It was intended to be water-tight. Large, hollow pontoons made from steel plates were attached to the front glacis plate and rear decking to give the necessary buoyancy. The front pontoon was internally divided into two "symmetrical sections" and each one was divided into three separate watertight compartments to minimize the effects of damage from flooding and shellfire.
|

The pontoons were attached by a system of "small clips" with a release inside the tank, to be engaged once it landed for ground combat operations. Its gun turret had a high-velocity Type 1 37 mm gun and a coaxial Type 97 light machine gun. A second Type 97 light machine gun was located in the tank's bow. The tank was capable of attaining speeds of 10 km/h in the water with a range of 140 km through two propellers situated at the rear of the hull, powered by the tank's engine.

There were plans to build a second, identical, Fietsflat on the IJ side of Amsterdam Central Station due to open September 2006. In April of the same year, the City Council did not approve of the 4 million euro budget. They opted for more flexible, faster and cheaper solutions with temporary parking spots on several locations, including pontoons and ferries.In Dutch: Blik op Nieuws Noord Holland: Géén tweede fietsflat bij CS In 2014 the City approved a large new underground bicycle parking facility underneath the Open Havenfront at Prins Hendrikkade, right opposite the Fietsflat.

Brothers Pete and Ernie Harris established their manufacturing business, Harris Manufacturing, in the 1940s and 50's. While looking for a way to expand their business, inspired by an increasing number of individuals building early pontoon boats on 55-gallon barrels and drop tanks from airplanes, the brothers founded Harris FloteBote Marine in 1957. The original Harris FloteBote pontoons were 20-feet in length with steel tubes. Dealers were not receptive to the large boats occupying the extra showroom space, as they were accustomed to typical 16-foot runabouts.

She added the Fiji Islands, the Russell Islands, New Guinea, the Admiralty Islands and Norfolk Island to her list of Pacific Island delivery ports. Carina continued her cargo missions until 12 July 1943, when she departed from Espiritu Santo and steamed home for an overhaul and crewmen's leave at San Francisco, California. This shipyard overhaul prepared Carina for service with distant voyages in support of the Liberation of the Philippines. Among other tasks, she carried pontoons from Pearl Harbor to Ulithi Atoll between 2 October 1944 and 31 December 1944.

Oberstleutnant Branger and the Unteroffizier were the first to be taken prisoner, while the two Germans remaining with the seaplane refused to budge and stayed on board until Plyhn approached them alone and after firing a warning shot took them prisoner. The captured Germans were handed over to the police.Sivertsen 2000: 36 The He 59 proved impossible to remove due to low tide. After attempts to pull it free had damaged the pontoons and wings beyond repair, it was towed out on the Leirfjord and sunk on 18 May.

The dock basin is home to a variety of bird wildlife with ducks, coots and cormorants in residence. Swans and various gulls spend time on the dock and herons may be seen feeding nearby in the river. In 2010 members of the Fylde Bird Club installed a number of gravel-filled tyres and slate shelters on the pontoons at the Preston Marina to attract common terns and entice them to breed. The project proved to a success and was followed by the club and local schools building over 170 breeding boxes to attract more birds.

The decision was made to commence the assault at night and as the river was not very wide at this point, planks would be used for the soldiers to cross in single file. Later, pontoons would be required for the artillery to cross the river. Field Marshal Douglas Haig, aware that the Germans were near exhaustion, initiated a series of operations designed to get British troops in strength across the river and clear a way for a move against the Sambre–Oise Canal, a further to the east.

During the last two decades accelerating developments have taken place around most of Sutton Pool area. This has mostly involved the building of distinctive modern style waterside blocks of flats which have prevented the realisation of David Mackay's plan for a seafront 'gateway' from Sutton Pool into the city centre which would have required the clearing of many of the few remaining historical streets and the redevelopment of Bretonside Bus Station. There has also been adverse comment about the recent extension of the many marina pontoons severely limiting the area of open water.

The USS Wompatuck underway, 20 April 1899. By 10:35am, the battle had been concluded. The Spanish squadron had been entirely destroyed, suffering casualties of three men killed, fourteen men wounded, four gunboats sunk or destroyed and three transports and pontoons burned to the waterline, while the Americans, on the other hand, had suffered no casualties. The only significant damage incurred by the American force was a three-pounder gun that broke loose from its rivets on the Wompatuck, though one of USS Wilmingtons guns was disabled due to Spanish gunfire for a few minutes.

At some point after the demise of the earlier enterprise utililising the pontoons built for the Steam vessel George Spraggs the licensee of the tavern on the Hayling side began operated the ferry using motor boats with his sons until his drowning in 1922. Following their father's death the sons Cecil, George and Jack continued the operation until 1961,. They seem also to have been joined by an Alan Spraggs, and Cecil was the engineer. They typically used 3 boats, two in service and one in the boatshed.

11th EA Division with its AA support then moved north up the Chindwin to Kalewa, an important ferry centre which was to be the crossing site for XXXIII Corps. A bridgehead was secured and the engineers began building a 1100-foot Bailey bridge on pontoons. Japanese air attacks had been slight up to this point, but now their aircraft made a determined attempt to knock out the bridge. Intense concentrations of fire by 52nd and the other AA units broke up the attacks, destroyed six aircraft, and ensured that the bridge remained intact.

Marina Rubicon Castillo de las Coloradas Marina Rubicon, one of the biggest ports on the Canary Islands, is situated about a 15-minute promenade walk from the town itself. It has 550 berths with finger system for monohull and multihull boats of up to 50 meters, in addition to an area for large length on the dock (up to 90 m) and a courtesy dinghy-dock located in anteport. All berths have turrets with water and electricity. The floating boarding pontoons have an aluminium structure, covered in tropical wood and anchored using berthing dolphins.

The was established in 1866. It provided river transport between Charenton and Suresnes with a fleet of paddle steamers, similar to those used since 1864 on the river Saône in Lyon and built in the Lyon district of La Mouche, from which the name Bateau Mouche comes. The service had a strong reputation with the public, and the Préfecture set the fares, timetables and frequencies. A steamboat of the , some time before 1917 Several companies swiftly followed: in 1876 the operated eighteen pontoons, twelve of them in Paris.

The pontoons were towed into position, moored by chains originally made for the SS Great Eastern, and linked to the mainland by two double bridges. The Cheshire, the first passenger ferry steamer to have a saloon, operated from Woodside in 1864. The iron pier at Eastham was built in 1874. On 26 November 1878, the ferry Gem, a paddle steamer operated from Seacombe by the Wallasey Local Board, collided with the Bowfell, a wooden sailing ship at anchor on the River Mersey; five people died as a result.

At dawn, six Battles from 103 Squadron attacked the pontoon bridges over the Meuse at Gaulier north of Sedan; all of the Battles returned and some of the pontoons may have been damaged. At four Battles attacked and returned safely. French apprehensions about the situation grew so intense that the decided to use obsolete Amiot 143 bombers and Barratt agreed to make a maximum effort. Hurricane squadrons from the north were to reinforce the AASF but still only to fly in the general area of the Battles along with French fighters.

Behind the water falls were huge pontoons that rose up and down as they rotated, creating a one-foot wave in the pool. As the park added more and more attractions, it became so famous by the 1920s that the Borough of Palisades Park, located just west of the amusement park, considered changing its name to avoid confusion among amusement park visitors. In 1928 the park introduced the Cyclone roller coaster, the third of Harry Traver's "Terrifying Triplets". Due to the high maintenance costs, the ride was removed six years later.

A top speed of was achieved, with the hydrofoil exhibiting rapid acceleration, good stability, and steering, along with the ability to take waves without difficulty. In 1913, Dr. Bell hired Walter Pinaud, a Sydney yacht designer and builder as well as the proprietor of Pinaud's Yacht Yard in Westmount, Nova Scotia, to work on the pontoons of the HD-4. Pinaud soon took over the boatyard at Bell Laboratories on Beinn Bhreagh, Bell's estate near Baddeck, Nova Scotia. Pinaud's experience in boat- building enabled him to make useful design changes to the HD-4.

The Stingray features a strut-braced parasol wing, a single-seat enclosed cockpit under a bubble canopy, retractable conventional landing gear and a single engine in pusher configuration. The aircraft is made from a combination of metal tubing, with its flying surfaces covered in Dacron sailcloth doped aircraft fabric and a reinforced fiberglass hull. Its span wing has a wing area of and is supported by a central pylon behind the cockpit, "V" struts and jury struts. The wing also mounts outrigger pontoons that provide stability on the water.

The incessant rain severely hampered operations and the Union army's mobile force's ability to keep supplies moving to their new positions. A large number of Warren's V Corps soldiers had to help the teamsters move wagons and horses through the mud and even to corduroy roads.Bearss, 2014, p. 358. Gravelly Run was swollen to three times its usual size and bridges and pontoons on Hatcher's Run were swept away. Skirmishers from the V Corps kept the Confederates mostly in their White Oak Road Line between the Boydton Plank Road and Claiborne Road on March 30.

Forces led by Dutch commander Isaac de Saint Martin drove Trunajaya's forces from Manukan, on the west bank further south from Singkal. They tried to cross the river there, but were unsuccessful due to heavy opposing fire and the depth of the water. They made another attempt on the night of 6–7 November, but their boats were sunk and it too failed. Hurdt was frustrated by the lack of progress, and gave Amangkurat an ultimatum that the VOC would withdraw unless the King supplied pontoons for the crossing, and matches for its soldiers' matchlocks.

In 1870, a contract was signed with a French company, Forges et Chantiers de la Mediteranée for construction of a third bridge, but the outbreak of war between France and Germany delayed the project, which was given instead to the British firm G. Wells in 1872. This bridge, completed in 1875, was long and wide and rested on 24 pontoons. It was built at a cost of 105,000 gold liras. It was used until 1912, when it was pulled upstream to replace the old Cisr-i Atik Bridge.

During peak hours, the ferries did not operate on a fixed schedule. The ferry landings are pontoons connected to a shell road by a small ramp, and are held in place by pilings in the river bottom. The ferries made a "figure-8" transit, always running upriver when departing, letting the current carry the boat downriver, then turning upriver to land on the opposite bank. The East Bank ferry landing was situated upriver of two busy grain elevators, limiting the boats' ability to maneuver and, when ships were present, obscuring the boats' radar.

In the 1930s, Bautista Buriasco bought shares in La Margariteña, a combine harvester manufacturer of Colonia Margarita, Santa Fe Province. In 1938 he moved the factory to the city of María Juana, where it continued producing agricultural machinery. After the World War II the company used military trucks to adapt them to transport cattle and grains. In 1944 Buriasco established a new company, "La Soberana", that started to produce cannons, pontoons for the Argentine Army, fuel tanks for YPF and water tank for Obras Sanitarias, the main water supply company of Argentina by then.

Kit manages to escape and, as the Phantom, evades the police outside the museum. Meanwhile, after Sala reveals that Diana is the Phantom’s girlfriend, she flies Drax, Quill, and Diana to the Devil’s Vortex, not knowing that the Phantom has managed to hitch a ride on one of the plane’s landing pontoons. On the island, Drax meets with the pirate Kabai Sengh, direct descendant of the Brotherhood’s original leader, who possesses the third Skull. Sengh warns Drax of the Fourth Skull’s existence, which controls the power of the other three.

The prisoners were moved to live on the adjacent pontoons. Prisoners relied on charity or their families for food, bedding and clothing. They were required to work 12 hours a day in the docks, earning 10-15 centimes, which they could spend on food and wine. Other prisoners were housed in prisons onshore, where conditions were apparently so bad that many prisoners would beg to be transferred to the hulks. By the early 19th century, the French urban population had increased from under six million to over 16 million, with a commensurate increase in crime.

These platforms have hulls (columns and pontoons) of sufficient buoyancy to cause the structure to float, but of weight sufficient to keep the structure upright. Semi-submersible platforms can be moved from place to place and can be ballasted up or down by altering the amount of flooding in buoyancy tanks. They are generally anchored by combinations of chain, wire rope or polyester rope, or both, during drilling and/or production operations, though they can also be kept in place by the use of dynamic positioning. Semi-submersibles can be used in water depths from .

An inflatable rubber hose around the turret ring created a waterproof seal between the hull and turret. The tank's 2 cm gun and coaxial machinegun were kept operational and could be fired while the tank was still making its way ashore. Because of the great width of the pontoons, Schwimmpanzer IIs were to be deployed from specially- modified Type C landing barges, from which they could be launched directly into open water from a large hatch cut into the stern. The Germans converted 52 of these tanks to amphibious use prior to Sea Lion's cancellation.

Twenty-two trestle, suspension, pontoon, and raft bridges were employed in the campaign. Engineers used all available materials in their bridges, including boards pulled from buildings, cotton bales, telegraph wire, vines, cane, and flatboats, in addition to the supplies forwarded from engineer depots upriver. The pontoon company of Sherman's corps ultimately brought along its inflatable rubber pontoons, which were employed in the crossing of the Big Black River. Once Grant decided to initiate a formal siege to reduce Vicksburg, he was faced with a critical shortage of trained engineer officers.

26 The Régiment de Piedmont, reinforced by a company of the Régiment des Gardes, tried to expel them from the pontoons and the road of faggots with great fierceness, but thanks to the presence of the Prince, who took the command of the attack, the Spaniards managed to cross the river and drove off the Régiment de Piemont from the riverside. The Maestro de Campo Alonso Pérez de Vivero y Menchaca, Count of Fuensaldaña, put then his soldiers to work in the digging of trenches to cover them from a possible counterattack.

The Shipyard Workers' Tenement Flat is another attraction which portrays a typical 'room and kitchen' worker's tenement flat, restored to its 1920s appearance. Most of the museum's floating vessels are moored at pontoons alongside Irvine Harbour. The moored ships located here vary from time to time, including the puffer Spartan, built in 1942 and typical of the puffers that were found throughout much of Western Scotland until the 1960s. For many years, the hull of the Clipper 'Carrick' or 'City of Adelaide' was a well-known landmark, located on a slipway at the museum.

A pontoon bridge is a collection of specialized, shallow draft boats or floats, connected together to cross a river or canal, with a track or deck attached on top. The water buoyancy supports the boats, limiting the maximum load to the total and point buoyancy of the pontoons or boats. The supporting boats or floats can be open or closed, temporary or permanent in installation, and made of rubber, metal, wood, or concrete. The decking may be temporary or permanent, and constructed out of wood, modular metal, or asphalt or concrete over a metal frame.

Floats (also called pontoons) are airtight hollow structures, similar to pressure vessels, designed to provide buoyancy in water. Their principal applications are in watercraft hulls, aircraft floats, floating pier, pontoon rhinos, pontoon causeways, and marine engineering applications such as salvage. During WWII the United States Navy Civil Engineer Corps developed a modular steel box (pontoon) for the Seabees to use. It was an industrial sized Lego system of pre-drilled pre-cut angle iron and steel plate that could be assembled anywhere for which they became famous for.

For propulsion, the Condor has two main engines built into the massive, pontoon-like structures that make up the main portion of the ship. A pair of secondary engines built onto the living area of the ship provide for maneuvering, and a rudder is attached to the stern to assist. During periods of inactivity, the ship can hover or land. Six anchors built into both the forward pontoons and living section allow the ship to anchor itself to cliffs, though the engines still need to be running to avoid over-stressing the anchors.

Bonaparte's view was confirmed when Gen. Claude Victor-Perrin, supported by Divisional General Joachim Murat’s cavalry, swiftly evicted FML Andreas O'Reilly von Ballinlough’s Austrian brigade from Marengo village that afternoon. Victor then deployed divisional generals Gaspard Amédée Gardanne and Jacques-Antoine de Chambarlhac de Laubespin's divisions along the Fontanone stream. Austrian headquarters debated building a bridge to the north to outflank the French, but the lack of pontoons and time forced the Austrians to cross the River Bormida and then launch a single, direct assault across the Fontanone bridge.

From Paris the aircraft flew to London and on to the north of England in order to prepare for the Atlantic Ocean crossing by re-installing pontoons and changing engines."Douglas World Cruiser Transport." Boeing. Retrieved: 7 July 2012. U.S. President Calvin Coolidge inspected the planes when they landed in Washington DC toward the end of the tour in September 1924 On 3 August 1924, en route from the Orkney Islands to Iceland, an oil pump failure forced the Boston down onto an uninviting sea less than halfway to the Faroes.

Originally developed by the German firm Eisenwerke Kaiserslautern (EWK, since 2002 acquired by General Dynamics European Land Systems), it succeeded the conceptually similar M2 made by the same company. Like its predecessor, the M3 traverses roads on its four wheels, deploying two large aluminium pontoons for buoyancy on water. Development of the M3 began in 1982, with the final prototype being delivered 10 years later in 1992.The Amphiclophy A first order of 64 serial vehicles was made in 1994, and it entered service with the German and British armies in 1996.
|
|
The M3 is self-deployable by road, operating as a 4x4 wheeled vehicle with a maximum road speed of 80 km/h. It is driven into the water for amphibious operation, for which it deploys two large aluminium pontoons, unfolding them along the length of its hull. In water, the M3 is propelled and steered by 2 fully traversable pump jets at speeds of up to 14 km/h. Multiple rigs may be joined by long connectors called "ramps", 4 of which are carried on each vehicle, to form a bridge across a water obstacle.

The extension was a single line; there was an opening bridge with a lifting span over the River Cleddau at Haverfordwest. Although there were a few dwellings there, Neyland had no pre-existing commerce whatever, and was created entirely by the SWM. A twice-weekly ferry to Waterford was started soon after the railway opening. As the berthing facilities were expanded, four pontoons were incorporated into the works from the Cornwall Railway, where they had been used for floating the main spans of the Royal Albert Bridge at Saltash.

SS-192 in drydock after salvage. The salvage of Squalus was commanded by Rear Admiral Cyrus W. Cole, Commander of the Portsmouth Naval Shipyard, who supervised salvage officer Lieutenant Floyd A. Tusler from the Construction Corps. Tusler's plan was to lift the submarine in three stages to prevent it from rising too quickly, out of control, with one end up, in which case there would be a high likelihood of it sinking again. For 50 days, divers worked to pass cables underneath the submarine and attach pontoons for buoyancy.

Upon reaching the torpedo room, they heard answering hammer blows from inside the boat. In 1923 the only way the salvage crew could get the men out of the submarine was to lift it physically from the mud using cranes or pontoons. One of the largest crane barges in the world, Ajax, built specifically for handling the gates of the canal locks, was in the Canal Zone. However, there had been a landslide at the famous Gaillard Cut and Ajax was on the other side of the slide, assisting in clearing the Canal.

This view was taken from off the port bow, showing F-4s port-side diving plane in the center. She is upside down, rolled to starboard approximately 120° from the vertical. A diving and engineering precedent was established with the Navy's raising of the submarine on 29 August 1915. Divers descended to attach cables to tow the boat into shallow water, Naval Constructor Julius A. Furer, Rear Admiral C.B.T. Moore, and Lieutenant C. Smith were able to do this with the use of specially devised and constructed pontoons.

The only pair whose boat is still seaworthy retrieve Mike and leave the others to take him ashore and get help; Sean and the others remain adrift upon the wreckage of tangled boats. A Coast Guard marine helicopter that Brody contacted arrives to tow them to shore, but the shark latches onto the chopper's pontoons, capsizing it and drowning the pilot. The shark knocks Sean into the water, and Marge is eaten while saving him. Brody finds Mike, who informs him of the situation before Brody sends him to safety.

The Navy tested an "underwater locator" in August 1949 by searching an area south of the Cape Hatteras Lighthouse for the wreck of Monitor. It found a long object bulky enough to be a shipwreck, in of water that was thought to be Monitor, but powerful currents negated attempts by divers to investigate.Clancy, 2013, p. 32 Retired Rear Admiral Edward Ellsberg proposed using external pontoons to raise the wreck in 1951, the same method of marine salvage he had used on the sunken submarine , for the cost of $250,000.

Near the end of the war on April 22, 1945 at 2pm a Mitsubishi A6M Zero two seater plane piloted by Shimbo and Ensign Chuhei Okubo in the second seat, overflew Seeadler Harbor at 14,000 feet. They saw what they thought were two "aircraft carriers", but were actually empty floating dry docks ABSD-2 and ABSD-4. On April 27, 1945 at 11:15pm a Nakajima B5N piloted by Takahashi dropped an aerial torpedo it hit one of the pontoons tanks in section G, damaging the dry dock. She was repaired and returned to service.

With a passenger load of only three lightly dressed persons, the HO3S-1s were primarily operated in the utility role by the marines; for the transport role, an additional nine tandem-rotor Piasecki-built HRP-1 helicopters were later added to the squadron.Rawlins 1976, p. 20. Eventually, the U.S. Navy would acquire a total of 88 HO3S-1 (S-51) helicopters. Thirty-nine additional specialized rescue helicopters were built, as the H-5G, in 1948, while 16 were fitted with pontoons as the H-5H amphibian in 1949.

The bigger sheerlegs usually have their own propulsion system and have a large accommodation facility on board, while smaller units are floating pontoons that need to be towed to their workplace by tugboats. Sheerlegs are commonly used for salvaging ships, assistance in shipbuilding, loading and unloading large cargo into ships, and bridge building. They have grown considerably larger over the last decades due to a marked increase in vessel, cargo, and component size (of ships, offshore oil rigs, and other large fabrications), resulting in heavier lifts both during construction and in salvage operations.

He was the Navy's first engineering test pilot and helped develop the first Navy-built seaplane, pontoons and hulls that overcame water suction, and a catapult to launch aircraft. As a member of the Navy Construction Corps, Richardson helped to design the hull of the Curtiss NC flying boats. On October 4, 1918, he performed the crucial test flight of NC-1, the first of these seaplanes, from Jamaica Bay. He then took the plane, with a full crew, for a shakedown flight to the Washington Navy Yard for inspection by Navy leadership.

As the second compartment rapidly flooded, the officers within shut the watertight doors to prevent flooding the adjacent compartments. When the seawater flooded the battery well, many of the officers and civilians in the second compartment were killed by chlorine gas. The 22 sailors in the first compartment were able to fight the flooding and retain a pocket of air until K-56s captain ran his boat aground on a sandbar. The next day, salvage ships lifted K-56 from the sand bar onto pontoons, and towed her to dock.

In those early years of the brand's identification, the logo also included a banner proclaiming the tires' "armored-cord" construction. The company's red, white, and blue logo would become one of the most easily recognized emblems in the tire industry. During World War II the company, known as Master Tire and Rubber, manufactured pontoons, landing boats, waterproof bags and camouflage items, inflatable barges, life jackets and tank decoys, as well as tires, to supply the Allied forces. The U.S. government recognized the company's contribution to the war effort in a 1945 ceremony bestowing the Army-Navy ‘E’ Award (for excellence).

The BHP facilities at Troughton Island were affected by very destructive winds and heavy rainfall from the cyclone's core, damaging the runway and buildings. Average wind speeds of 139 km/h (86 mph) and a maximum gust of 174 km/h (108 mph) were recorded before communications were lost. Only minor damage was received at the pearling facilities at Vansittart Bay and Kuri Bay, mainly to floating pontoons. A number of places reported daily rainfall totals in excess of 100 mm (3.9 inches) including 223 mm (8.78 in) in Kalumburu on 11 December, and 174 mm (6.85 in) in Ellendake on 13 December.

Pontoons were secured to her sides and she was towed up the Mississippi, Illinois, and Chicago Rivers to Lake Michigan where her screws and mast were replaced. On 5 May 1950 she was placed in commission, in reserve to serve as the flagship for six patrol vessels of the 9th Naval District engaged in the training of naval reservists on the Great Lakes.U.S. Navy All Hands magazine January 1962, pp. 16-18. Daniel A. Joy was decommissioned on 1 May 1965 and sold for scrap to the North American Smelting Corporation in Wilmington, Delaware on 1 March 1966.

On 2 February 1814, he distinguished himself again at the Battle of Montmirail, and the following day was made général de division. On 19 March that same year, he impetuously attacked the enemy rearguard, captured a group of pontoons and closely pursued the Allies. During the Hundred Days, general Letort offered his services to Napoleon, who accepted and put him in command of the dragoons of the Imperial Guard. On 15 June, at the moment Napoleon gave the order to attack elements of Ziethen's Prussian I Corps (hidden in the woods of Fleurus), the Prussians began to retire.

She transited the Panama Canal on 4 August and, while en route to San Diego received word of the Japanese surrender. After reaching San Diego on the 17th, she unloaded the pontoons at Port Hueneme, California on the 27th, and got under way for Hawaii. Upon her arrival at Pearl Harbor on 6 September, Adonis set to work converting LSMs and LCIs into troop carriers which could be used to help return military personnel to the United States. She remained in Hawaiian waters through 25 October, when the ship shaped a course for Guam where she operated until early December.

On February 13, 1979, a powerful, winter windstorm caused a catastrophic failure of the floating Hood Canal Bridge. With the sustained winds at 85 mph (137 km/h) and gusts estimated at 120 mph (193 km/h), the bridge finally succumbed at about 7:00 a.m. The western drawspan and the pontoons of the western half of the bridge had broken loose and sank, forcing those living on the Kitsap Peninsula to take an inconvenient detour. A Hood Canal ferry run was re-established by utilizing the Kulshan between Lofall and South Point across the canal just south of the unusable bridge.

The same day, Navy carrier-based planes attacked the bridge, scoring eight direct hits, and brought it down. Attacks against the Han River pontoon bridges at Seoul do not seem to have been successful until FEAF ordered the Bomber Command to lay delayed action bombs alongside the bridges on August 27, set to detonate at night. This method of attack seems to have caused such heavy casualties among the North Korean labor force trying to keep the pontoons in repair that they finally abandoned the effort. These bridges remained unfinished when the UN forces recaptured Seoul later in the year.

Shallow-draft German Siebel ferries like this example plied the waters of Lake Ladoga from 1942–43 The Siebel ferries were originated by aircraft designer Fritz Siebel and intended for use in Germany's planned 1940 invasion of England, Operation Sea Lion. They consisted of two heavy Army bridging pontoons braced together with iron cross-beams and covered by a sturdy wooden deck. The ferries initially had a pair of Ford V-8 truck engines in each aft pontoon end, connected to standard water screws. Further power came from three 600 hp surplus aircraft engines mounted on an elevated scaffolding spanning the rear deck.

The 27,000-capacity grandstand and floating platform of The Float@Marina Bay, with the Singapore Flyer in the background. Many considerations were taken into account during the design phase for the construction of the floating platform. The Defence Science and Technology Agency, the platform's chief planner and developer, had to keep in mind not just its size and the load it could bear, but also make sure the structure can be relocated and reconfigured to meet the requirements of different events. As a result, the platform is made of smaller platforms of pontoons, each comprising hundreds of parts.

Although this method has largely been replaced by modern methods, some dredging is done by small-scale miners using suction dredges. These are small machines that float on the water and are usually operated by one or two people. A suction dredge consists of a sluice box supported by pontoons, attached to a suction hose which is controlled by a miner working beneath the water. State dredging permits in many of the United States gold dredging areas specify a seasonal time period and area closures to avoid conflicts between dredgers and the spawning time of fish populations.

Land-based German bombers used for search duties proved inadequate in range, so bomber air bases were constructed along the coast to facilitate an air net over the Baltic and North seas. Following this, the Luftwaffe determined to procure a purpose-built air-sea rescue seaplane, choosing the Heinkel He 59, a twin-engine biplane with pontoons. A total of 14 He 59s were sent to be fitted with first aid equipment, electrically heated sleeping bags, artificial respiration equipment, a floor hatch with a telescoping ladder to reach the water, a hoist, signaling devices, and lockers to hold all the gear.

On 20 July 1942, when Rommel was driving towards Egypt, General Headquarters (GHQ) ordered the construction of two bridges across the Nile to allow Eighth Army's armour to manoeuvre to the south if the Cairo defences were attacked. The task was assigned to X CTRE under Lt-Col E.N. Bickford. The sites chosen were at Helwan and Wasta, where the widths to be bridged were 2688 feet (820 m) and 2760 feet (840 m) respectively, and the difference between high and low water was about 22 feet (7 m). Pontoons were unavailable, so local feluccas were used to make a bridge of boats.

However, ships of Algomas size were too long to pass through the Welland Canal, so Algoma was cut in half, with the bow and stern moved through the canal separately on pontoons. The ship was rejoined in Buffalo, New York, and cabins were added, increasing the tonnage to 1,773 tons. Additional work was done on the cabins during the winter of 1883–1884, including the installation of electric lighting; Algoma and its sister ships were probably the first Great Lakes ships to be electrified. The newly outfitted Algoma, costing a total of $450,000 to build, was relaunched on May 11, 1884.

In consultation with engineers from Pionier-Battalion 47, Siebel settled on a combination of four 75 hp Ford V-8 engines (two each mounted side-by-side in the aft end of the pontoons) linked to standard marine propellers. For auxiliary power, three BMW 6U 750 hp aircraft engines could mount on elevated platforms along the aft edge of the cargo deck, turning airscrew propellers. Early problems with this arrangement included engine failure due to insufficient cooling, solved by linking the water-cooled aircraft engines to the diesel truck engines via piping to the pontoon compartments.

Erica Goodemay, New Solar Plants Generate Floating Green Power, New York Times, 20 May 2016. In May 2008, the Far Niente Winery in Oakville, California, pioneered the world's first floatovoltaic system by installing 994 solar PV modules with a total capacity of 477 kW onto 130 pontoons and floating them on the winery's irrigation pond. The primary benefit of such a system is that it avoids the need to sacrifice valuable land area that could be used for another purpose. In the case of the Far Niente Winery, it saved that would have been required for a land-based system.

A large-diameter pipe closed at the aft end is attached to the keel of each float and fills with water. While it remains submerged buoyancy forces cancel the weight of the trapped water and the weight of the tube is effectively zero. But if the boat heels enough to bring the weather float out of the water, this effect no longer operates and the water provides a heavy ballast weight on the float, creating a righting moment. In the abstract sense, the principles at work govern the stability of all boats and ships including those without lateral pontoons.

The 109th Engineer Battalion, a South Dakota National Guard unit called up during the Korean War, arrived in Germany in June 1951 and was quartered in Taylor Barracks assigned to the 11th Engineer Group. The 109th was in charge of nine bridges over the Rhine river. Standard M2 Bailey Bridges were mounted on M4 floating metal pontoons, with half of the bridge on each side of the river. The bridge halves would swing from each side of the river and when they met in the middle of the river they were fastened together with huge steel pins.

During World War II White returned to military service with the rank of brigadier. He held the posts of Director of Ports and IWT at the War Office and Deputy Director, Department of Transportation Tn(5). He was part of the team involved in planning and designing of the "artificial" Mulberry harbours, having been responsible for the development of the four-legged floating pontoons and the floating roadways that became the Spud pier heads and the Whale piers of these two harbours. These were used to supply Allied forces in France after the D-day landings in Normandy.

Like its predecessors, the Nieuport VI was a wire-braced, mid-wing monoplane of conventional design, powered by a single engine in the nose driving a tractor propeller. It differed, however, in being a three-seater rather than a single seater (a bench for two passengers fitted in tandem with the pilot's seat) and in using steel for part of its internal structure where earlier designs had used wood only.Sanger 2002, p.25 Produced initially as a seaplane and designated VI.G, it had twin pontoons as undercarriage, with a teardrop-shaped auxiliary float under the tail.

Log of HMS Tamar, 10 April 1914 "1·30 Welland Ship Company hulked on board" Hulks have a variety of uses such as housing, prisons, salvage pontoons, gambling sites, naval training, or cargo storage. Although the term hulk can be used to refer to an abandoned wreck or shell, it is much more commonly applied to hulls that are still performing a useful function. In the days of sail, many hulls served longer as hulks than they did as functional ships. Wooden ships were often hulked when the hull structure became too old and weak to withstand the stresses of sailing.

Inshore diving commonly includes underwater work in support of construction projects Civil engineering works are one of the major applications of inshore and inland coastal diving projects. Much of the work is either underwater inspection or engineering construction or repair work. The types of dive sites involved is varied, and divers can be found working in harbours and lakes, on hydroelectric dams, in rivers and around bridges and pontoons, with a large amount of this work being done in freshwater. Divers may be required to inspect and repair outfalls with penetrations exceeding , which require special safety precautions.

Due to the weight of various reinforcements over the years, the bridge deck ultimately sat about lower over the water than it did originally. Since the bridge was built in the early 1960s, prior to the implementation of modern earthquake standards, its hollow support structures would have likely failed during a major earthquake. Additionally, vibrations induced by storm surges and strong winds could have compromised the drawspan, anchor cables, and pontoons, subjecting them to structural failure. Even for storms below the maximum threshold for failure to occur, Washington State Department of Transportation (WSDOT) still closed the floating bridge to traffic.

The Energen device consists of a series of semi-submerged cylindrical pivoting torque tubes connected to two large cylindrical pontoons. The wave-induced movement of these torque tubes is resisted by a hydraulic system which pumps high pressure oil through hydraulic motors. The hydraulic motors drive electrical generators to produce electricity. A 50th scale model has been tested at the Council for Scientific and Industrial Research in Stellenbosch and using actual wave data off the South African coast it is estimated that a single device will produce 1.4 MW of power, or 979 GW hours of electricity per annum.

After a second attack from the French-based bombers, 2 Group were to attack from England. At eight Breguets 693s with fifteen Hurricane and fifteen Bloch 152 fighter escorts, attacked German tanks at Bazeilles and the pontoons between Douzy and Vrigne-sur-Meuse against scattered anti-aircraft and fighter opposition; all the Breguets returned. Just after noon, eight LeO 451s and 13 Amiot 143s also with fifteen Hurricane and fifteen Bloch 152 fighter escorts, attacked the same targets; three Amiots and a LeO were shot down. From to 45 Battles attacked the bridges and 18 Battles with eight Blenheims went for German columns.

In the meantime, Gellibrand placed the 45th Battalion at Imlay's disposal, although they did not immediately move forward from their position behind the 106th Brigade. German engineers attempted to place pontoon bridges across the Ancre north of Dernancourt to allow assembling troops to cross, but the pontoons were soon riddled and many engineers killed and wounded by guns of the 12th Machine Gun Company. When Imlay became aware of this concentration of German troops, he ordered a company of the 45th Battalion to move to his support lines. During the day, the 47th Battalion suffered 75 casualties.

Tuchman, 553–554 At Orşova, where the Danube narrows at the Iron Gates gorge, the column crossed to the right bank using pontoons and boats over eight days. Their first target was Vidin, previously the capital of Western Bulgaria and then under Turkish control. The ruler of Vidin, Ivan Sratsimir of Bulgaria, having no desire to fight for his Turkish conquerors against an overwhelming force of crusaders, promptly surrendered. The only bloodshed was the execution of Turkish officers in the defending garrison, though the incident served to further convince the French that Turks were incapable of challenging the crusaders in the field.

Taisun, the world's largest gantry crane, with a lifting capacity of 20,000 metric tonnes, has taken over seven years to plan and an additional 12 months for the preparation of its design framework. The crane, capable of muscling up to 10,000 cars in one lift, allows the mating of an entire outfitted deck box of a semi-submersible rig onto its hull/pontoons in one single operation. The shipyard states that this will reduce work hazards at high altitudes and in the open sea. The lifting of the complete deck box reduces man-hours by as much as half.

Her last winter in 1940 was so difficult that Suur Tõll had to escort ships all the way from Stockholm and Danzig to Tallinn. In the 1920s, Estonia did not possess a dry dock large enough to accommodate the 3,619-ton Suur Tõll and as a result the icebreaker was drydocked in Copenhagen, Denmark, in 1923. As a response, the Tallinn-based Riigi Laevatehased combined their 2,000-ton and 3,000-ton floating docks with pontoons. In 1927, the shipyard replaced Suur Tõlls old boilers with new ones purchased from Vulcan and heightened the bridge by one deck to improve visibility over the bow.

The LC2 featured a large intake for the radiators in the center of the nose of the car just as the LC1 had, unlike the contemporary Porsche 956s which drew all their air from behind and to the sides of the cockpit. This air was also directed through the side bodywork to feed the intercoolers for the turbochargers. Inlets for the rear brake cooling ducts were also integrated onto the side bodywork of the car, immediately behind the doors. At the rear, a pontoon-style design was adapted to the fenders with the large wing bridging across the pontoons.

Three Canadair CL-215 amphibious flying boats The following is a list of seaplanes and amphibious aircraft, which includes floatplanes and flying boats, by country of origin. Seaplanes are any aircraft that has the capability of landing on water while amphibious aircraft are equipped with wheels to alight on land, as well as being able to land on the water. Flying boats rely on the fuselage or hull for buoyancy, while floatplanes rely on external pontoons or floats. Some experimental aircraft used specially designed skis to skim across the water but did not always have a corresponding ability to float.

1 p. 23 Two Ottoman divisions plus one more in reserve, with camel and horse units, were ready to depart in mid-January. The advance across the Sinai took ten days, tracked by British aircraft, even though German aircraft stationed in Palestine in turn aided the Ottomans and later flew some bombing missions in support of the main attack.First World War - Willmott, H.P. Dorling Kindersley, 2003, Page 87 Kress von Kressenstein's force moved south by rail, continuing on foot via el Auja carrying iron pontoons for crossing and attacking the Suez Canal at Serapeum and Tussum.

Harbour Board Office The railway ceased being used on 4 May 1970, although the lines remained in place for a further nine years. Most of the warehouses on the quay were subsequently demolished, being replaced by offices and the Red Funnel ferry terminals. Also, a marina was constructed on the east side of the pier, inshore of the high-speed ferry pontoons. One of the last survivors of the original buildings, the Grade II listed Harbour Board offices, was, until 2015, a gentleman's club; another survivor, the former Geddes Warehouse, also listed Grade II, has been converted into a boutique hotel and restaurant.

Each pontoon was hinged at one end to allow it to float open, and was pulled closed by a steam-powered cable. As well as allowing for river traffic, this allowed end-of-winter ice floes to pass down the river without risk of damaging the structure. The pontoons were built with a timber-framed deck which could be raised or lowered by as much as 18 feet to allow for changes in the river level, which can vary by as much as 22-1/2 feet (at extreme high water, the bridge could not be used).

She and General Craufurd would have been tasked with towing one of three pontoons, each of which would have been capable of landing hundreds of men as well as tanks, guns and transport. The landing had been designed to coincide with Allied success at the 3rd Battle of Ypres which opened on 31 July 1917. This offensive faltered, however, so it was deemed too dangerous to attempt an assault on the coast. The monitors, which had been training at South West Reach in the River Thames without leave since July, were ordered to Portsmouth on 2 October.

However, since the works didn't go as planned, in November 2019 the deadline was moved to March 2020 and the next nautical season. When construction of the supporting piles began, the slabs from the previous embankment were discovered so as several submerged vessels. The pier's bridge will be also long, with 20 piles, while the pontoon will rest on two dolphins. The piles are being founded to the depth of in order to endure the pressure of river ice, while some pontoons will be attached to the piles so that it may rise and fall, following the change of the Danube's water level.

The Austrians improved their earthworks between 9 and 14 January, and later augmented their batteries with nine pieces of large caliber, brought to the siege after the successful completion of the assault on Kehl, with another several thousand men. Fürstenberg ordered the reinforcement of the ring of soldiers surrounding Hüningen, and day by day, the situation for the garrison within the fortress became more dire. The batteries called Charles and Elizabeth that girded the fortress downstream (see map in box) poured balls and shells into the fort, destroying the pontoons connecting the island fortifications to the mainland on both sides.

Major-General Herbert Taylor Siborne (18 October 1826 – 16 May 1902) was a British Army officer in the Royal Engineers and a military historian. Siborne was born in 1826, the second son of the officer and historian Captain William Siborne. He joined the Royal Engineers in 1846, and served in the Kaffir War 1851–53, and also in the expedition against the Basutos in December 1852, when he had charge of the pontoons by which the troops crossed the Orange and Caledon rivers. He was present at the action of the Berea, and was mentioned in General Orders.

The Crusader was trialled with two pontoons that could be attached or removed, the tracks driving the tank in the water. The "Medium Tank A/T 1" was a tank with inbuilt buoyancy some long and tall. The Valentine, then the M4 Sherman medium tank were made amphibious with the addition of a rubberized canvas screen to provide additional buoyancy and propellers driven by the main engine to give propulsion. These were DD tanks (from "Duplex Drive") and the Sherman DD was used on D-Day to provide close fire support on the beaches during the initial landings.

The WD.2 was a development of the Avro 503 that had been built under licence by Gotha as the WD.1, and like it, was a conventional three-bay biplane with tandem, open cockpits. The landing gear comprised twin pontoons and dispensed with the small pontoon carried under the tail of the WD.1. Machines built for the Imperial German Navy were unarmed, but those supplied to the Ottoman aviation squadrons carried a 7.92 mm (.312 in) machine gun in a ring mount on the upper wing, accessible to the observer, whose seat was located directly below it.

The sides of the ships were bullet proof, and was designed with a ramp on the bow for disembarkation. A plan was devised to land British heavy tanks from pontoons in support of the Third Battle of Ypres, but this was abandoned.Fletcher, D British Mark IV tank New Vanguard, Osprey Publishing US Landing Craft Mechanized in Kiska during the Aleutian Islands Campaign. During the inter-war period, the combination of the negative experience at Gallipoli and economic stringency contributed to the delay in procuring equipment and adopting a universal doctrine for amphibious operations in the Royal Navy.

IRBs are of great value when patrolling a beach especially ocean surf beaches where either the surf is too powerful or the beach too large to perform rescues effectively on a board. Prior to the start of a patrol, it is the driver's responsibility to ensure the craft is correctly set up and ready for patrolling duties. Typically this will involve inflating the crafts four pontoons to the correct pressure with a hand/foot or electric pump. The motor is test run in a tank of fresh water to check full function and reliability before installation to the transom.

That same evening, Luxembourg personally led a detachment from Gerpinnes (together with bridging pontoons), to establish a crossing of the Sambre at Ham. A fortified position at Froidmont (garrisoned by about 100 men) was soon compelled to surrender after artillery was brought across the river; a simultaneous attack by French dragoons seized an enemy redoubt that had been abandoned at the approach of Luxembourg's army. With the bridgehead secure, the rest of the French army (apart from the heavy baggage that had remained on the south bank at Ham) crossed the Sambre on 30 June. (See map).

On 20 September 2001, Stena Explorer suffered a generator fire in one of her pontoons. Whilst going astern (reversing) into dock at her berth in Holyhead, a fire was detected in her auxiliary (generator) engine room in the port pontoon. Shortly after, the CCTV system, normally used for visual docking, became disabled due to lack of power. Knowing that just-completed checks showed that fire doors (lasting at least one hour) were closed, permission to shut off the engine in question was (correctly) denied by the Master of the Ship until final approach line-up with the Linkspan was confirmed.

When the United States Coast Guard destroyer rammed and sank the submarine on the afternoon of 17 December 1927 off Provincetown, Massachusetts, Wright immediately loaded six salvage pontoons at the Norfolk Navy Yard and set out for the scene of the disaster. Although delayed by strong Atlantic gales, Wright reached Provincetown, via Boston, on the afternoon of 21 December. Meanwhile, on the day that Wright departed Norfolk, her commanding officer, specially detached, Captain Ernest J. King, took the train from Norfolk to New York and proceeded thence by plane to Provincetown. Arriving on board at 1315 on 18 December, Capt.

He sent infantry across in rubber boats, appropriated the bridging tackle of the 5th Panzer Division, personally grabbed a light machine gun to fight off a French counterattack supported by tanks, and went into the water himself, encouraging the sappers and helping lash together the pontoons. By 16 May Rommel reached Avesnes, and contravening all orders and doctrine, he pressed on to Cateau. That night, the French II Army Corps was shattered and on 17 May, Rommel's forces took 10,000 prisoners, losing 36 men in the process. He was surprised to find out only his vanguard had followed his tempestuous surge.

Iolair on Elbe river, 1990 The Brazilian Petrobras P-51 semi-submersible oil platform The advantages of the semi- submersible vessel stability were soon recognized for offshore construction when in 1978 Heerema Marine Contractors constructed the two sister crane vessels called Balder and Hermod. These semi-submersible crane vessels (SSCV) consist of two lower hulls (pontoons), three columns on each pontoon and an upper hull. Shortly after J. Ray McDermott and Saipem also introduced SSCVs, resulting in two new enormous vessels DB-102 (now Thialf) and Saipem 7000, capable of lifting respectively 14,200 and 14,000 tons.

Western Marine Shipyard Limited is a public listed shipbuilding company based in Chattogram, Bangladesh. The shipyard has constructed various types of vessels till date, including ocean going multi purpose cargo vessels, passenger vessels & boats, oil tankers, ro-ro ferry, pontoons, barges, fishing trawlers, dredgers, tug boats, container vessels, etc. Western Marine Shipyard is the country's largest shipbuilder, standing with over 42 acres of land, modernized into a shipyard consisting of all sorts of tech & heavy machinery. Sitting in the Eastern Bank of the Karnaphuli river in Chittagong, it is an employment source for 3500 people; including skilled and semi skilled labors.

A pier, raised over the water rather than within it, is commonly used for cases where the weight or volume of cargos will be low. Smaller and more modern wharves are sometimes built on flotation devices (pontoons) to keep them at the same level as the ship, even during changing tides. In everyday parlance the term quay is common in the United Kingdom, Canada, Australia, and many other Commonwealth countries, and the Republic of Ireland, whereas the term wharf is more common in the United States. In some contexts wharf and quay may be used to mean pier, berth, or jetty.

This was quickly replaced by a larger enclosure in 1931 with a central diving tower and fixed piled platforms and pontoons. When the small sea wall and fence along the beachfront was provided in the upper level promenade was built named "Notting Parade". Along this, the W. A. Notting Memorial is sited immediately west of the Kiosk. The large curved masonry stuccoed Roman Seat was erected in 1927 by the Nielsen Park Trust, with a plaque honouring William Albert Notting, who was instrumental in having the reserve established through his involvement with the Harbour Foreshore Vigilance Committee.

The Army also had crossing means (boats, ferries and pontoons) enough to carry 300-400 men, with their weapons, in one trip, with more in reserve. 52nd Army faced the German 57th, 332nd, 72nd and 167th Infantry Divisions and the 5th SS Panzer Division Wiking, which had very few tanks and was operating as infantry. These divisions had between 4,000-5,000 men each under command. Overall, the terrain, with a large river to cross, much broken and wooded ground, and many inhabited localities, including substantial buildings and factories in the vicinity of Cherkassy, would make this a difficult operation.

Renwick was elected to Parliament in 1900 as Conservative member for Newcastle-upon-Tyne, serving from 1900 until his defeat in 1906. Renwick was born in Newcastle upon Tyne. He joined shipowners Pyman, Bell & Co as a clerk and then co-founded his own business, Fisher, Renwick & Co. He had particularly large interests in drydocks, including the world's first ever floating repair docks, the Tyne Pontoons at Wallsend, which he sold to Swan Hunter & Wigham Richardson Ltd in 1903.Who's Who Una Duval, suffragette, campaigning at the by-election The Newcastle Independent Labour Party selected J.

The 42nd Division moved up through Le Quesnoy and the Forest of Mormal and relieved the New Zealanders on 6 November. The advance was continued through Hautmont on 8 November, but 125 Bde was unable to cross the Sambre because the pontoons had not arrived, so it retraced its steps to its overnight billets near Pont sur Sambre and crossed there. The Fusiliers then forced back the enemy rearguards, and after dark its patrols went forward and the 1/7th Bn cleared them off the high ground near Fort d'Hautmont, one of the outer forts of the Fortress of Maubeuge.Gibbon, pp. 191–5.

It also absorbs the shock of earthquakes, allowing buildings and their related communities to remain stable. Arx Pax is working with Republic of Kiribati and Pacific Rising to solve for sustainable development challenges associated with rising sea levels. Arx Pax, the company involved in this technology has proposed building a “floating village” project in north San Jose's Alviso hamlet, deploying a group of pontoons beneath the buildings to protect the development from floods and earthquakes. Originally developed for earthquakes as an alternative to Base Isolation the floating foundation decouples the structure from the earth with a simple patented method consisting of three parts.

Raising the Mary Rose meant overcoming a number of delicate problems that had never been encountered before. The raising of the Swedish warship Vasa 1959–61 was the only comparable precedent, but it had been a relatively straightforward operation since the hull was completely intact and rested upright on the seabed. It had been raised with basically the same methods as were in use in Tudor England: cables were slung under the hull and attached to two pontoons on either side of the ship which was then gradually raised and towed into shallower waters. Only one third of the Mary Rose was intact and she lay deeply embedded in mud.

The bridge over 1,264 feet (385 meters) is constructed with an area of 24 feet (7 meters) of the vehicle lanes, 8-foot (2-meter) for bike paths / bike, and 5 feet of sidewalks. It can accommodate a load of 500 tons for each 100 feet (30 meters). To complete this bridge, 4 pontoons used to carry concrete mixers, cement, sand and cranes weighing up to 120 with 50 ton lift in which a total of 2 piers built specifically to fit the mould of concrete beams. The bridge was built on 48 piles of special steel imported from Germany and reinforced concrete piles 82.

Besides the need to protect the flanks of its motorized spearheads, the German Army high command, Oberkommando des Heeres (OKH), also saw the importance of Kharkiv as an industrial center and railroad hub. Capturing the city meant that the Southwestern and Southern Front had to fall back on Voronezh and Stalingrad as their major transport hubs. When, in the second week of October, the rainy season of the Rasputitsa (the 'mud' season) and the poor logistics in the area between the Dnepr and the front, (all the bridges had collapsed during combat and ice threatened the pontoons), caused the offensive to stall.Margry 2001, p.

Help arrived that winter when University of Washington rowing coach Hiram Boardman Conibear convinced the brothers to come to Seattle and build boats for the university after hearing about their fine work in Canada. In 1916 the shell building business was still struggling, and they began building pontoons for William E. Boeing’s new airplane company, Boeing. George eventually became foreman of the assembly department, Dick became boat-builder for Yale University, and their father returned to England. In 1922 George returned to the University of Washington to build boats again, and in 1923, the unknown Washington rowing team went east and won the national sport rowing championship in a Pocock boat.

Windlass and Salvager assisted in a four-point moor over on 10 August 1948 and conducted salvage tests off Piney Point, Maryland on the former German U-boat until 25 August. Hurricane Carol interrupted operations as she swept through the area on 30 and 31 August, but both salvage vessels rode out the storm without damage, despite the force 5 winds. Windlass took the almost-submerged U-1105 undertow, supporting her partially with pontoons, and moored the ship on 28 September. Windlass and Salvager then performed various moors and salvage operations on the submarine's hulk off Piney Point until 18 November before returning to Bayonne. There, Windlass remained into 1949.

Unable to do so, the campaign ended in mid-October and the 15th Pennsylvania returned to Camp Lingle (named for 1st Lt. Harvey S. Lingle of Company G, killed at Mossy Creek) at Wauhatchie Station, where it camped until December 20. Between December 28, 1864, and March 2, 1865, the 15th Pennsylvania was encamped at Huntsville, Alabama. In the immediate aftermath of the Battle of Nashville, it pursued the supply trains of Hood's army, catching and destroying all his pontoons near Russellville, Alabama, on December 31, and more than 300 wagons that day and the first day of 1865, penetrating into Mississippi as far as Fulton.

The ship was launched on 1 July 1908, underwent an initial fitting-out, and then in mid-September 1909 was transferred to Kiel by a crew composed of dockyard workers for a final fitting-out. However, the water level in the Weser River was low at this time of year, so six pontoons had to be attached to the ship to reduce her draft. Even so, it took two attempts before the ship cleared the river. On 16 October 1909, before Westfalen was commissioned into the fleet, the ship took part in a ceremony for the opening of the third set of locks in the Kaiser Wilhelm Canal in Kiel.

Following shakedown exercises along the Florida gulf coast, LST-1038 returned to New Orleans for availability then steamed to Gulfport, Mississippi and Mobile, Alabama, taking on side-carry pontoons at the former and cargo ammunition at the latter. Loaded by 15 March, she departed for the Panama Canal en route to the western Pacific. Steaming independently, she arrived at Ulithi on 4 May, departing again on the 8th with convoy UOL 11, then headed west to the embattled Ryukyus. On 16 May she sighted Kerama Retto and, after reporting to CTG 31.15, commenced supplying ammunition to fleet units as necessary, primarily DDs and DMSs.

Note also the 2cm Flakvierling 38 mounted atop the wheelhouse (center of picture) for AA protection. With its simplicity of design, sturdy construction, good sea-keeping, and the ease with which it could be disassembled and shipped via rail to virtually any point on the Continent, the Siebel ferry proved a useful and adaptable amphibious vessel for transporting troops, vehicles, and supplies across open water wherever needed by Germans. It was also easily-configured to serve a variety of purposes, from minelaying to convoy escort.

He was thanked in general orders, mentioned in despatches (London Gazette, 8 May 1814), and on 23 June received promotion for his services to the brevet rank of major. He was also appointed military secretary to Bentinck, commander-in-chief in the Mediterranean, and occupied the post until his return to England in August. In November 1814 Tylden joined the army in the Netherlands, and took charge of the defences of Antwerp. In 1815 he organised and commanded a train of eighty pontoons, with which he took part in the operations of the allies, the march to and capture of Paris, and the occupation of France.

Aircraft landing gear includes wheels equipped with solid shock absorbers on light planes, and air/oil oleo struts on larger aircraft. Skis are used for operating from snow and floats from water. (Helicopters use skids, pontoons or wheels depending on their size and role.) The landing gear represents 2.5 to 5% of the MTOW and 1.5 to 1.75% of the aircraft cost but 20% of the airframe direct maintenance cost. A suitably-designed wheel can support , tolerate a ground speed of 300 km/h and roll a distance of ; it has a 20,000 hours time between overhaul and a 60,000 hours or 20 years life time.

Wittekind and sister-ship Willehad were both quickly found to be deficient in cargo space, and plans were made to lengthen both vessels (though Willehad was never lengthened). Wittekind 's bridge was moved forward and a cargo hatch was installed behind it. After this, the ship was cut into two parts forward of the bridge's new position, and a new section was inserted, which greatly increased the cargo capacity. Sources disagree as to where the procedure was performed with one reporting it was performed at the Seebeck Yard in Germany, while another claims it was done by Tyne Pontoons & Drydock Co., at Newcastle.Drechsel, V. I, pp. 158–59.

The units were constructed over away in a casting basin at Port Kembla and then towed to Sydney Harbour. A trench was dredged before the arrival of the IMTs and then the IMTs were lowered into the trench by a system of pontoons and control towers. After the IMTs were in place the trenches were backfilled and then a rock armour was placed over the top to protect the units against marine hazards, such as anchors or sinking vessels. The land tunnels were constructed by a combination of driving and cut-and-cover techniques, designed to be strong enough to withstand the impact of earthquakes.

Fifteen to eighteen divers were kept busy for nearly 2,000 underwater hours during the salvage, patching her hull, rigging chains, cutting away unwanted structure and executing many other tasks. After her tophamper had been removed, the salvage pontoons were used to pull the ship upright while air was pumped into her to lighten the load. The parbuckling, or righting attempt, was begun on 11 April 1942, and on 22 April, the crane barge Gaylord, of the Hawaiian Dredging Company, was rigged to Oglala to pull her over, if needed, as she was righted the following day. The operation was a success and Oglala came upright to rest on her bottom.

Seen from the north (Termination Point) Hood Canal Bridge from Buena Vista Cemetery, Port Gamble, Washington. Aerial view of the bridge's southeast half, with drawspan section at far left The design and planning process for the Hood Canal Bridge took nearly a decade amid criticism from some engineers throughout that time. Critics questioned the use of floating pontoons over salt water, especially at a location with high tide fluctuations and the concern that the funneling effect of the Hood Canal might magnify the intensity of winds and tides. The depth of the water, however, made construction of support columns for other bridge types prohibitively expensive.

He resolutely goes on alone and finds the French encampment. He patiently hides in the rocks watching the business of the camp for several days. Finally, he goes in by night, kills two sentries, and spreads highly flammable grease and oil (kept in cauldrons by the French for tarring rope, greasing cordage, and waterproofing their boats) over the pontoons and timber and rope, and sets it all on fire. From his hideout in the rocks, he sees the whole encampment burn, and is pleased with his success; he never learns that orders had arrived only that day for the French to burn the encampment themselves since Masséna had ordered a retreat.

Maurice Dean Derby 37699146, Browning Automatic Rifleman, Co. A, 17th Infantry Regiment, 7th Infantry Division, he related that "On the night of the landing (Okinawa, 1 April 1945) we were kept awake all night because the Tank Crews were beating on the pontoons with sledgehammers to remove them from the Tanks." The tanks were Co. B, 711 Tank Battalion. Compared with the DD, the floats were bulky and harder to stow, limiting the number of tanks that could be carried in a landing craft. However, the system was more seaworthy and had the advantage of allowing the Sherman to fire its main gun as it approached the beach.

During planning for an invasion of England in 1940 (Operation Sea Lion), the Germans also worked on developing amphibious tanks capable of directly supporting infantry during a beach assault. German Tauchpanzer III under test (1940) The Schwimmpanzer II was a modified version of the Panzer II which, at 8.9 tons, was light enough to float with the attachment of long rectangular boxes to either side of the tank's hull. The boxes were made of aluminum and filled with Kapok sacks to preserve buoyancy if water leaked into the pontoons. Motive power came from the tank's own tracks which were connected by rods to a propeller shaft running through each float.

The park encompasses the entire headland from the northern waterfront with its netted public swimming pool and children's playground, to the picnic area at Flatrock lookout, around to Parsley Bay which has a large new boat ramp, multiple pontoons for water access, a large parking area for cars with room for boat trailers and a park with barbecue facilities. Yachts are anchored here with permanent moorings and kayaks can be hired in Parsley Bay to explore the waterways. The waterfront trail around McKell park is a beautiful short walk. There is also a multi-use sporting field and children's playground near Baden Powell Hall on Brooklyn Road.

The challenges of flying in Arctic conditions meant that the Fokker Universals flew on pontoons during the short spring and summer, and then converted to skis for the fall and winter months. Constant attention to snowdrifts that might trap the men and equipment and keeping runways and waterways clear meant that in the 14-month operation proceeded slowly. One of the main advantages was the use of Inuit supplies of parkas and clothing that were much better suited to the Arctic than regulation clothing provided by the RCAF. Inuit hunters also acted as guides and accompanied the pilot and mechanic (who also acted as a photographer) aboard each aircraft.

This can continue until the vessel inverts completely with the pontoons again floating on the surface but the rest of the vessel underwater. At this point, the upside-down vessel will be highly stable. If, on the other hand, the vessel is designed and loaded so that each pontoon can support the vessel's entire weight (plus any lateral forces that arise like wind), the center of gravity cannot move transversely beyond the center of buoyancy at the most extreme tipping angle, and the pontoon effect cannot occur. Note, however, that this is not the sole effect to be taken into consideration when assessing the likelihood of capsize.

Tanjung Priok Dock of 8,000 tons was 156.40 m long overall. The pontoon deck was 146.40 m long. Beam was 29 m, internal width on the pontoon deck was 21.4 m. The pontoons had a hold of 3.2 m. The sides were 10 m high. The 8,000 tons regarded the displacement of the ships which the dock could lift. The weight of the dock itself would be 4,000 ton. The maximum displacement would be 12,500 ton with a freeboard on the pontoon deck of 30 cm. Which is what will happen if one puts a ship of 8,000t displacement on top of one of 4,000t.

A landing operation would begin at dawn under the command of Rear-Admiral Bacon and an army division in three parties of about each, would disembark on the beaches near Middelkirke, covered by a naval bombardment and a smoke screen generated by eighty small vessels. Trawlers would carry telephone cable ashore and tanks would disembark from the landing pontoons and climb the sea-wall to cover the infantry landing. The infantry would have four 13-pounder guns and two light howitzers and each wing of the landing had a motor machine-gun battery. For mobility, each landing party had more than and three motorbikes.

At 03:00 on 19 November, Tanzanian Lieutenant Colonel Ben Msuya dispatched a contingent to the northern bank to cover a team which was assembling the pontoons. Within three hours the bridge was completed, and the Tanzanians began clearing mines they had left behind along the northern bank before the Ugandan invasion. One soldier was killed and three wounded when they accidentally detonated a mine, but by 12:00 all of the other mines had been removed. On 20 November Tanzanian patrols began exploring the area along the northern bank of the Kagera River, discovering dead civilians and destroyed property left by the Uganda Army.

G and T Smith built ketches and smacks between 1890 and the start of the First World War. They built two steam drifters during the war, the only ships to be built at Rye during this period, and the same yard built pontoons which were used to detonate magnetic mines during the Second World War. They also built eight minesweepers, each long, of which two were despatched to Singapore. H J Phillips set up his yard in 1913, and the company survived two world wars and the depression of the 1930s, to continue building and repairing boats both for the fishing industry and the growing leisure industry.

A single company of pontonniers could construct a bridge of up to 80 pontoons (a span of some 120 to 150 metres long) in just under seven hours, an impressive feat even by today's standards. In addition to the pontonniers, there were companies of sappers, to deal with enemy fortifications. They were used far less often in their intended role than the pontonniers. However, since the emperor had learned in his early campaigns (such as the Siege of Acre) that it was better to bypass and isolate fixed fortifications, if possible, than to directly assault them, the sapper companies were usually put to other tasks.

WKYW began broadcasting on March 24, 1947, with a 25-minute preview of programs before initiating full service the next day. The station's original power was 1,000 watts, broadcast from the transmitter site off River Road; because of its location near the Ohio River, the transmitter building was raised on aluminum pontoons. The daytime-only outlet claimed several firsts: its off-air hours were silenced by a mattress company, and one Christmas it recorded its entire programming on tape so all of its employees—save for an engineer—could take the holiday off. In its programming, WKYW emphasized music, with a minimum of talk.

The aircraft was redesigned and these modifications were introduced in the sequential new models of the Metalplane called the H-45 and H-47. The aircraft now could accommodate passengers and mail. To do this, they had to specifically change the aircraft such as: moving the wing above the fuselage so six seats could be added; enclosing the cockpit and adding windows and leather padding the interior of the aircraft for the passengers' comfort. Offering different types of radial engines that could be incorporated per the customers' request (both Wright and Pratt & Whitney) and different types of landing gear that could be fitted too (such as skis, wheels, and pontoons).

Gravelly Run was swollen to three times its usual size and bridges and pontoons on Hatcher's Run were swept away. Skirmishers from the Union V Corps kept the Confederates in their White Oak Road Line between the Boydton Plank Road and Claiborne Road on March 30. Despite incomplete information and somewhat vague and conflicting orders from Meade and Grant, on Grant's order, Warren pushed the Union V Corps forward to strengthen his hold on a part of the Boydton Plank Road and the V Corps entrenched a line to cover that road from its intersection with Dabney Mill Road south to Gravelly Run.Bearss, 2014, p. 363.

On 13 July 1939, the stern was raised successfully, but when the men attempted to free the bow from the hard blue clay, the vessel began to rise far too quickly, slipping its cables. Ascending vertically, the submarine broke the surface, and of the bow reached into the air for not more than ten seconds before she sank once again all the way to the bottom. Momsen said of the mishap, "pontoons were smashed, hoses cut and I might add, hearts were broken." After 20 more days of preparation, with a radically redesigned pontoon and cable arrangement, the next lift was successful, as were two further operations.

As security improved in the area civilians began to return to Năm Căn. The initial building operation at Nam Can was to install a floating base on concrete pontoons to provide security while the Seabees worked on the shore to build an Advanced Tactical Support Base, called Solid Anchor, however the swampy sands weren't up to carrying the loads of a modern naval base, neither the heavy equipment nor the naval base structures. The contractor took over the dredging and fill needed for the base and a runway. Eventually, by 1970, Nam Can was going to need 640,000 cubic yards of fill to support a base and airfield.

After completion, Rich sailed from the builder's yard at Bay City to Chicago, Illinois, where they arrived on 24 September. From there, they went through the Chicago Sanitary and Ship Canal and down the Chicago River to Joliet, Illinois, where pontoons were attached to the ship so it could be pushed down the Des Plaines River, Illinois River, and Mississippi River as part of a barge train. After arriving at the Todd Johnson Shipyard in Algiers, Louisiana, on the west bank of the Mississippi at New Orleans, the rest of the crew reported aboard, and Rich was commissioned on 1 October 1943, Lieutenant Commander E. A. Michel, Jr., USNR, in command.

Ground troops prefer to deal with physical obstacles by circumventing them as rapidly as possible, thus avoiding becoming stationary targets to the enemy direct and indirect fire weapons, and aircraft.p.296, Liddell Hart Where this is not possible, in modern warfare the most expedient measures taken against constructed or urban obstacles are to either use armoured vehicles, preferably tanks, to remove the obstacle, or to demolish them by firing High Explosive munitions at them. Where combat engineers are present, they can perform this using their specialist skills and tools or vehicles. In the case of natural obstacles, specialist engineering equipment is usually required to negotiate the obstacle, commonly bridging or pontoons.

Soviet forces withdraw across the Amu Darya, 1989 In 1979 Soviet troops of the 40th Army crossed the border at Termez via a series of pontoons as part of the Soviet Invasion of Afghanistan, en route to Mazar-i-Sharif and Kabul. They later constructed the Friendship Bridge, which officially opened in 1982, however its strategic importance led to it being a target of the Mujahideen insurgency. The Soviet army left Afghanistan via the bridge in 1989. The bridge was closed from 1997 to 2001 due to Uzbek fears over Taliban insurgency, before re-opening to allow aid in following their fall in 2001.

Colonel Sazonov was ordered to cross the 1239th and the 2nd Battalion of the 1235th into this bridgehead the next night. By the end of November 15 this bridgehead was 7 km wide and 5 km deep. However, German reinforcements continued to arrive and tilt the balance of forces in their favor. The battle for the bridgehead went on for several days, as antitank units and the few tanks and self-propelled guns of 52nd Army crossed the river on pontoons, and by the end of November 18 the 373rd had taken Vasilitsa and Sosnovka, and the bridgehead had been expanded to 16 km in width and nine km in depth.

The Kokandis responded by breaking the dykes and flooding the surrounding area. Having brought no scaling ladders or heavy artillery, Blaramberg saw that he could not take the citadel with its 25-foot-high walls. He therefore captured the outworks, burnt everything in the area and retired to Fort Aralsk. The later-famous Yakub Beg had commanded the fort at one time, but it is not clear if he was in command during this first battle. Next summer the Russians assembled a force of over 2000 men, over 2000 each of horses, camels and oxen, 777 wagons, bridging timber, pontoons and the steamer “Perovsky”.

The nearby Royal Harwich Yacht Club is a Victorian yacht club formed in 1843 and has had many Royal connections; Prince Philip is the current Patron. The yacht club moved to its present site soon after World War II after its previous premises had been demolished for the expansion of the Navy Yard at Harwich. In 1973, floating pontoons were stationed at the bottom of the club lawn, which then provided the club with its own marina. The Royal Harwich Yacht Club supports The Woolverstone Project, which has Paul Heiney as Patron and provides sailing for people with disabilities at Woolverstone and the nearby Alton Water reservoir.

On their way. they engaged a Spanish gunboat, which they sank, and were fired on by shore troops at Niguero. Reaching Manzanillo, the three American vessels engaged an enemy torpedo boat, four gunboats, four pontoons, a battery of field artillery, enemy troops firing from the shore, and a Spanish-held fort. When the smoke and fire lifted after an hour and 40 minutes of sharp fighting, Hornet had been disabled but towed to safety by Wompatuck, Hist had been hit 11 times; the Spanish had received the worst of the battle, losing a gunboat, a pontoon, and a sloop loaded with troops as well as suffering serious damage to the gun and torpedo boats.

Arriving at the Greek isle of Imbros, yet more new orders were received, transferring control of the Train from the British Admiralty, which had been given operational control of the Royal Australian Navy by the Federal Government on 10 August 1914, to the British Army and attaching it to IX Army Corps under Lt. General Stopford which was to land at Suvla Bay on 7 August. While at Imbros, the Train received a grand total of five days of instruction on the use of their pontoons, a task which needed six days worth of unloading and reloading the equipment. After this minimal training, they were considered ready to land under enemy fire.

An angler in a float tube catching a black bass A float tube, also known as a belly boat or kick boat, is a small, lightweight inflatable fishing craft which anglers use to fish from. They were originally doughnut-shaped boats with an underwater seat in the "hole." Still, modern designs include a V-shape with pontoons on either side and the seat raised above the water allowing the legs of the angler to be the only part of the body to be submerged. Float tubes are used for many aspects of fishing, such as flyfishing for trout or lure fishing for largemouth bass, and enable the angler to fish areas otherwise not fishable from the bank.

36 The Seiran was specifically designed for use aboard the submarines and could carry an bomb at . To fit inside the narrow confines of the hangar, the floats were removed and stowed, the wings rotated 90 degrees and folded backward hydraulically against the fuselage, the horizontal stabilizers folded down and the top of the vertical stabilizer folded over so the overall forward profile of the aircraft was within the diameter of its propeller. When deployed for flight, the aircraft had a wingspan of and a length of . A crew of four could prepare and launch all three in 30 minutes (or 15 minutes if the planes' pontoons were not first attached, which would make recovery impossible).

Cumberland pontoons were folding pontoon bridges developed during the American Civil War to facilitate the movement of Union forces across the rivers of the Mid-South as the Federal forces advanced southward through Tennessee and Georgia. Early pontoon bridges during the Civil War were heavy and awkward, and required special long-geared pontoon carriers to transport them to the site of the planned river crossing. There were two main types--the French- designed wooden bateau (known in the army as a "Cincinnati pontoon") and the Russian pontoon, a canvas boat. Both types were twenty-two feet in length and took considerable time to set up, requiring several men to lift into position and pin the individual sections together.

Póvoa de Varzim Marina near the South Breakwater. Póvoa Marina is a public marina using floating pontoons built by the City Hall of Póvoa de Varzim in June 1999 according to a project by Clube Naval Povoense, the local yacht club, and the management of the area was delivered by the city hall to the club. The marina is financially self-sustainable and is a nautical activities support marina, that should not be confused with real estate equipments called "marina" found in Southern Portugal, and the access to the docks are restricted. It has a growing popularity, especially noticeable in Northern Portugal and has a planned expansion to the area near Casino da Póvoa.

Trains would be halted from the bridge in the event of a major windstorm, with gusts of from the north or from the south. The design of the system, which would make East Link the first railway over a floating bridge ever constructed, was recognized by Popular Science magazine in their 2017 "Best of What's New" awards. The design of the seismic system and steel frames to be installed inside the floating pontoons added $225 million in construction costs, increasing the construction budget by 46 percent, and was paid for using contingency funds. The use of the floating bridge for light rail service remained controversial after the passage of Sound Transit 2 in 2008.

Sir George Renwick, 1st Baronet (8 March 1850 – 19 June 1931) was an English politician and shipowner. Renwick was born in Newcastle upon Tyne. He joined shipowners Pyman, Bell & Co as a clerk and then co-founded his own business, Fisher, Renwick & Co. He had particularly large interests in drydocks, including the world's first-ever floating repair docks, the Tyne Pontoons at Wallsend, which he sold to Swan Hunter & Wigham Richardson Ltd in 1903. He was the co-founder and chairman of Manchester Dry Docks Ltd on the Manchester Ship Canal and joint managing director of Fisher, Renwick, Manchester-London Steamers Ltd, also based on the Manchester Ship Canal and running scheduled steamer services between Manchester and London.

This page describes the specific phenomenon described above.) The pontoon effect is theoretically possible whenever the vessel's entire weight exceeds the buoyancy of the pontoon(s) on either side. However, the pontoon effect is more likely in vessels with a high center of gravity and low or non-existent displacement other than the pontoons. A pontoon vessel such as a catamaran floats in a level position when the center of gravity of the entire vessel (including its load) is above the center of buoyancy. This is the opposite of the case in a traditional or displacement hull vessel, which derives positive stability from having its center of buoyancy above the center of gravity.

In proper practice, the "bat" prefix (as in batmobile or batarang) is rarely used by Batman himself when referring to his equipment, particularly after some portrayals (primarily the 1960s Batman live-action television show and the Super Friends animated series) stretched the practice to campy proportions. The 1960s television series Batman has an arsenal that includes such "bat-" names as the bat-computer, bat-scanner, bat-radar, bat- cuffs, bat-pontoons, bat-drinking water dispenser, bat-camera with polarized bat-filter, bat-shark repellent bat-spray, and bat-rope. The storyline "A Death in the Family" suggests that given Batman's grim nature, he is unlikely to have adopted the "bat" prefix on his own.

The Eastside is also served by the Interstate 90 floating bridges completed in 1940 and 1989, carrying traffic across Mercer Island to and from Bellevue. The original Evergreen Point Floating Bridge was designed before the implementation of modern earthquake engineering standards, with vulnerabilities in its hollow support structures that could have failed in a major earthquake. Additionally, near the end of its lifetime, vibrations induced by storm surges and strong winds were able to compromise the aging drawspan, anchor cables, and pontoons, leading to structural failure in a major storm. Even if the storms were below the maximum threshold for failure to occur, Washington State Department of Transportation (WSDOT) would still close the floating bridge to traffic.

Builders trials before her pre-commissioning cruise were done in Lake Huron. After completion, Weiss sailed from the builder's yard at Bay City to Chicago, Illinois. From there, they went through the Chicago Sanitary and Ship Canal and down the Chicago River to Joliet, Illinois, where pontoons were attached to the ship so it could be pushed down the Des Plaines River, Illinois River, and Mississippi River as part of a barge train. After arriving at the Todd Johnson Shipyard in Algiers, Louisiana, on the west bank of the Mississippi at New Orleans, the rest of the crew reported aboard, and Weiss was commissioned at New Orleans, on 7 July 1945, with Lieutenant Commander Thomas D. Morris in command.

The pontoons were fitted with small planes at either side of their nose ends to protect the propeller and to reduce the tendency for the nose ends of the floats to submerge while taxiing,"The Paris Aero Salon" 1912, 1026–27 and "stepped" keels."Reflections on the Monaco Meeting" 1913, 485 Since being a seaplane precluded the possibility of the pilot swinging the propeller by hand in order to start the engine, a crank was provided inside the cockpit that wound a spring that could be used to turn the engine over. The Type VI also featured a joystick for lateral control in place of the Blériot-style "cloche" controls used on earlier Nieuport designs.Hartmann 2006, p.

The outcome was a scaled-up version of Curtiss' work for the United States Navy and his Curtiss Model F. With Porte also as Chief Test Pilot, development and testing of two prototypes proceeded rapidly, despite the inevitable surprises and teething troubles inherent in new engines, hull and fuselage. The Wanamaker Flier was a conventional biplane design with two-bay, unstaggered wings of unequal span with two tractor engines mounted side by side above the fuselage in the interplane gap. Wingtip pontoons were attached directly below the lower wings near their tips. The aircraft resembled Curtiss' earlier flying boat designs, but was considerably larger in order to carry enough fuel to cover 1,100 mi (1,770 km).

The large ailerons were mounted in the interplane gap, their span continuing past the wings themselves, and as before were controlled by a shoulder yoke accommodating sideways "leaning" movements by the pilot to operate them. The Model E was designed and built as a two-seater, although in practice some of the lower- powered versions were converted to single-seaters. Black pontoons on the wingtips of A-1 slanted diagonally backward toward the water to reduce friction on water and serve to balance aircraft on water. On the bottom of each pontoon is a little hydroplane of wood measuring 3 inches wide by ¼ inch thick to further aid in balance and reduce friction.

The Army designated it the R-8 and intended to race the aircraft against the Navy in the 1924 Pulitzer Trophy Race in Fairfield, Ohio, but it was destroyed in a crash during training shortly before the competition killing the pilot, First Lieutenant Alexander Pearson, Jr.. The remaining R2C had its wheeled undercarriage replaced by pontoons during 1924 in preparation for that year's Schneider Trophy race, but the event was cancelled due to a lack of competitors. As it was, the aircraft won that year's Pulitzer Trophy in the seaplane class with an average speed of 227.5 mph (364.9 km/h). The aircraft ended its days training pilots for the 1925 and 1926 Schneider Trophy races.

Nonetheless, the Navy created a floating Mobile Riverine Base (MRB) by assigning barracks ships, and barrage barges (non-self propelled) to house both Army and Navy personnel, provide communications and staff support, mooring and support facilities on Ammi pontoons alongside, and refit, rearm, and resupply stores. The MRB also included repair ships (ARLs) and supply ships (LSTs-Landing Ship Tanks). The ships of the MRB also had helicopter landing capabilities, and provided air resupply and medical air evacuation ("dust off") capability, and had significant medical care facilities aboard. Thus, the entire force could move throughout the major rivers of the Delta, and launch troops, on boats, into assault operations deep into the narrowest rivulets and canals.

Following her fitting out at Pensacola and shakedown training out of Panama City, Florida LST-57 returned to New Orleans where she took on board and a cargo of diesel fuel. Clearing the "Crescent City" on 25 February 1944 LST-57 proceeded independently to New York City. Spending five days there (during which time she embarked two Navy doctors and 40 corpsmen) the tank landing ship proceeded to Davisville, Rhode Island where the tank deck was loaded with 358 tons of pontoons: "no better a cargo for the sub-infested Atlantic," observed the ship's historian wryly. After an overnight stay at Boston, LST-57 joined a convoy bound for Halifax, Nova Scotia.

The aircraft's structure was made completely of fiberglass, making the Marvel the first example of an all-composite aircraft. The boundary layer control system used a blower driven by the engine to draw suction through more than one million tiny holes in the wings and fuselage, while instead of conventional flaps the Marvel used a form of wing warping to deflect the wing trailing edges to vary the wing's camber. The aircraft's tail surfaces were attached to the duct around the propeller, extending behind the duct. The undercarriage, of the so-called "Pantobase" configuration, with tandem wheels fitted within two sprung wooden pontoons, was meant to allow operation from rough surfaces, or even from water.

The rear diffusers exited between the pontoons and underneath the wing. The LC2s were modified over their lifetime, with a multitude of modifications being made each season to the cars' aerodynamics, including adapting brake duct inlets beneath the headlights. The Ferrari V8 was modified in 1984, bringing the displacement back up to 3.0-litres in an attempt to increase reliability and horsepower while improved engine electronics from Magneti Marelli allowed the larger engine to use the same amount of fuel as the previous version. In total, seven LC2s were built under the direction of Lancia, while a further two were built for Gianni Mussato without official backing after the program had ended.

Phase 1, including the weir, fish pass and landscaping was completed in March 2020, enabling small boats to use the York Stream half of the ring. Shanly Homes had completed the Picturehouse and Chapel Wharf phases of the development at Chapel Arches, set around a large water basin on the waterway. The third phase of their development, Waterside Quarter, was expected to be completed in 2021 together with the final linking section of the York Stream arm of the waterway ’Ring’. An access ramp and pontoons at Chapel Arches will provide a boat loading facility and storage for canoes and small boats in the two western (closed) arches, to assist with maintenance of the waterway.

Division traveling through the Black Forest via Oberkirch, and the Reserve, with most of the artillery and horse, by the valley at Freiburg im Breisgau, where they would find more forage, and then over the mountains past the Titisee to Löffingen and Hüfingen.Jourdan, p. 97. The major part of the imperial army, under command of the Archduke Charles', had wintered immediately east of the Lech, which Jourdan knew, because he had sent agents into Germany with instructions to identify the location and strength of his enemy. This was less than distant; any passage over the Lech was facilitated by available bridges, both of permanent construction and temporary pontoons and a traverse through friendly territory.

Prior to the opening of the bridge in 1959, the quickest way from Auckland to the North Shore was by passenger or vehicular ferry. By road, the shortest route was via the Northwestern Motorway (then complete only between Great North Road and Lincoln Road), Massey, Riverhead, and Albany, a distance of approximately .Auckland to North Shore: pre-Harbour Bridge As early as 1860, engineer Fred Bell, commissioned by North Shore farmers who wanted to herd animals to market in Auckland, had proposed a harbour crossing in the general vicinity of the bridge. It would have used floating pontoons, but the plan failed due to the £16,000 cost estimate ($1.9 million, adjusted for inflation as of March 2017).

While he did this, he would send a sizeable detachment in the opposite direction towards Lee's fortifications at Richmond to keep Lee guessing as to what Burnside was attempting to do. Burnside would then cross the Rappahannock at Fredericksburg, wheel his army left, and then advance towards Richmond behind Lee's fortifications, forcing him into an open battle where the North's superior numbers would inevitably win. Due to bureaucratic delays, delays in the vital pontoons needed to cross the Rappahannock at Fredericksburg, and luck on General Lee's part, Burnside was unable to attack until December 11, long after Lee had moved the majority of his forces from Richmond to the outskirts of Fredericksburg.

In the late 1860s, the Milwaukee Road's agent John Lawler conceived a ferry crossing, using barges with rail tracks on their decks. Because there are two channels separated by an island, each channel required a barge which was pulled across by cables, and a small rail yard crossing the island connecting the two ferries. This allowed transshipment of railroad cars without unloading, but was still less than efficient. A better solution was found by Michael Spettel and Lawler, who patented a permanent pontoon bridge system to span the river in 1874. This comprised piled trestles built out into the river, and two pontoons: A 210-foot unit on the east channel, and a 227-foot unit on the west.

Preparations begin early in the morning when people begin to decorate their boats, or the small wooden terraces on rooftops from where they can admire the fireworks. At sunset, Saint Mark's basin begins to fill with up with boats of all kinds, festooned with balloons and garlands, and thousands of Venetians await the fireworks while dining on the boats. Around 10 o'clock at night, from pontoons placed nearby the island of San Giorgio Maggiore, the fireworks begin and Saint Mark's basin becomes one of the most atmospheric stages in the world. The fireworks last for around 45 to 60 minutes, illuminating the night and arousing intense emotions in both Venetians and visitors.

The company designed and built launches, sailboats, hydroplanes and cruisers up to 60'. In 1911 The Detroit News reported that the company had designed and built the fastest step bottom hydroplane in the United States, named Kitty Hawk II. That same year the company gained attention after designing and building the first successful pontoons for Russell Alger's Wright Brothers Model B plane.Mayea Boats Heritage Frank Trenholm Coffyn used the hydroplane in 1912 to take off and land on the Hudson River, enabling him to capture aerial video of the New York skyline for the first time in history. By September 1911 Louis T. Mayea had taken control of the company and renamed the firm to Mayea Boat Works.

The bridges had been left behind in his retreat from Columbia because they lacked wagons to transport them, and pontoons requested from Thomas in Nashville had not arrived. Schofield needed time to repair the permanent bridges spanning the river—a burned wagon bridge and an intact railroad bridge. He ordered his engineers to rebuild the wagon bridge and to lay planking over the undamaged railroad bridge to enable it to carry wagons and troops. His supply train parked in the side streets to keep the main pike open, while wagons continued to cross the river, first via a ford next to the burned-out pike bridge, and later in the afternoon by the two makeshift bridges.

During the winter, simple footbridges supported by pontoons were laid out – making the crossing free of charge. The first bascule bridge was used 1924-1971 There are currently tree places where it’s possible to cross the canal on foot or by car, plus two railway bridges. The northernmost link is the Mälarbron bridge, which has three predecessors: the swing bridge from the 19th century, and another swing bridge that was used between 1910 and 1924. Both stood about 150 meters south of the current Mälarbron bridge. In 1924, the first bascule bridge opened. It was often referred to as simply "Klaffbron" or ”Landsvägsbron” (English: “the Bascule bridge” or "the Country Road Bridge").

Unlike her half-sisters, the ship spent five years on the stocks before she was ready to be launched, partially due to frequent changes in design, although Northumberland was much closer to completion. The additional weight caused her stick for an hour on the slipway before she slid halfway down with her stern only supported by air, threatening to buckle the ship. Efforts by hydraulic jacks and tugboats failed to get her into the water on the next spring tide failed, but the use of pontoons on 17 April 1866 proved successful. Her builders went into bankruptcy while the ship was being launched and the liquidators seized Northumberland as a company asset once she was in the water.

For example, the 1960s television show depicted a Batboat, Bat-Sub, and Batcycle, among other bat-themed vehicles. The 1960s television series Batman has an arsenal that includes such "bat-" names as the Bat-computer, Bat- scanner, bat-radar, bat-cuffs, bat-pontoons, bat-drinking water dispenser, bat-camera with polarized bat-filter, bat-shark repellent bat-spray, and Bat- rope. The storyline "A Death in the Family" suggests that given Batman's grim nature, he is unlikely to have adopted the "bat" prefix on his own. In The Dark Knight Returns, Batman tells Carrie Kelley that the original Robin came up with the name "Batmobile" when he was young, since that is what a kid would call Batman's vehicle.

The clubhouse in Osprey Quay Portland Harbour and Weymouth Bay are the main areas used for sailing. The harbour covers an area of , and is ideal for sailing as it is exposed to reliable winds from most directions, but is sheltered from large waves and currents by Chesil Beach and the breakwaters. The clubhouse houses facilities on two floors, including a gymnasium, seven lecture and meeting rooms for 260 people, an event hall with kitchens and a bar, VIP meeting rooms and offices, a lounge bar and cafeteria seating 350 people, and two balconies. The outside of the academy complex has a slipway and two deep water slipways, 30 pontoons with disabled access, cranage and boat hoists, boat storage and parking areas.

The cold deep sea water (<10°C) is pumped to the sea surface area to suppress the sea surface temperature (>26°C) by artificial means using electricity produced by mega scale floating wind turbine plants on the deep sea. The lower sea water surface temperature would enhance the local ambient pressure so that atmospheric landward winds are created. For upwelling the cold sea water, a stationary hydraulically driven propeller (≈50 m diameter similar to a nuclear powered submarine propeller) is located on the deep sea floor at 500 to 1000 m depth with a flexible draft tube extending up to the sea surface. The draft tube is anchored to the sea bed at its bottom side and top side to floating pontoons at the sea surface.

In the U.S. Wanamaker's commission built on Glen Curtiss' previous development and experience with the Model F for the U.S. Navy which rapidly resulted in the America, designed under Porte's supervision following his study and rearrangement of the flight plan; the aircraft was a conventional biplane design with two-bay, unstaggered wings of unequal span with two pusher inline engines mounted side-by-side above the fuselage in the interplane gap. Wingtip pontoons were attached directly below the lower wings near their tips. The design (later developed into the Model H), resembled Curtiss' earlier flying boats, but was built considerably larger so it could carry enough fuel to cover . The three crew members were accommodated in a fully enclosed cabin.

Major P.F. Kaymakova led his battalion of the 1168th Rifle Regiment over first, with the rest of the 346th crossing soon after, followed by the 216th and 257th Rifle Divisions. A few heavy weapons, including some 45mm antitank guns, were brought over on shallow-draft pontoons, but mostly the men were limited to what they could carry. There were no Axis troops within 5 km of the crossing site, and although it was mostly carried out in broad daylight, it was hours before the enemy was aware of the crossing. Before they could react the bridgehead was expanded to a size they could only hope to contain, but without tanks or heavy weapons 10th Corps could not break through the screening forces rushed in by 17th Army.

The modern commercial town centre has migrated north-west of the harbour area and above it and contains the transport hubs, main services, shopping and nightlife. The harbour has undergone major regeneration including the new Albert Strange Pontoons, a more pedestrian-friendly promenade, street lighting and seating. The North BayThe North Bay has traditionally been the more peaceful end of the resort and is home to Peasholm Park which, in June 2007, was restored to its Japanese-themed glory, complete with reconstructed pagoda, a new boat house was added in 2018. For many years a mock maritime battle (based on the Battle of the River Plate) has been regularly re-enacted on the boating lake with large model boats and fireworks throughout the summer holiday season.

75px Colonel Clayton's force consisted of seven officers and 230 enlisted men from the 18th Illinois Infantry, a detachment of five officers and 260 men from the 28th Wisconsin Infantry, and 600 men, four mountain howitzers and two steel rifled guns from the 1st Indiana, 5th Kansas and 7th Missouri Cavalry (US) units. The infantry portion of the expedition was commanded by Lieutenant-Colonel Samuel Marks of the 18th Illinois and the cavalry portion was under the command of Lieutenant-Colonel Wilton Jenkins of the 5th Kansas cavalry. In addition to the men and guns, Clayton's force also carried eight pontoons, mounted on wagon wheels, along with them to bridge streams as they came to them as well as a small wagon train of supplies.

The balance of 9 January, and that night were spent at anchor with occasional air raids. Next day she departed for Leyte, the focal point for future movements replacing Hollandia, and remained there until 22 January 1945. On 27 January, she began a resupply run to Lingayen Gulf, discharging cargo and personnel and departing 8 February for Mindoro Island to take on a load for Leyte Gulf. From 15 February to 6 March 1945, was spent in the Leyte Gulf area, LST-22 departing for Manila, on 14 March, and returning to Leyte, on 26 March 1945.

From 1941 it equipped and repaired motor torpedo and motor gun boats and motor launches for the Navy's Coastal Forces; and between 1942 and 1944 the Creek and Point Clear were a large landing craft training base. The shipyards also built many small craft for the Navy and RAF and thousands of pontoons for Army. Local war heroes included the Merchant Navy officer Leslie Frost and the fighter pilot Roy Whitehead, who both lost their lives. (National Archive Admiralty, RAF and Ministry of Defence files in ADM 1 and 199, AIR 27, 28 and DEFE 1 series; research—including veterans' interviews by J P Foynes, used in "Battle of the East Coast 1939-1945"—published 1994; and "Under the White Ensign"-1993).

The bombardment became more intense on the evening of June 25, and at 1 o'clock on the morning of June 26 the battle began with a diversionary attack on the Malmö Castle (Swedish: Malmöhus slott), followed by two frontal assaults on the city, one at the southern gate (Söderport) and one at the eastern gate (Österport). The Danes used fascines, ladders and pontoons to cross the moat. After fierce fighting Danish forces under the command of Siegfried von Bibow were able to break through the defense close to the eastern gate. However, as soon as Danish troops reached the crest of the town wall the Danish artillery ceased firing, which gave the Swedish defenders the opportunity to man their guns.

On July 19, 1913, he passed a Signal Corps-required flying test administered by the Aero Club of America (even though he had received an ACA aviator license in 1911) and received ACA Expert Aviator's Certificate No. 15, which also qualified him to be rated as a Military Aviator. After S.C. No 7 became a total loss in August, Lahm's small detachment received a new aircraft, S.C. No. 13, a Wright C Speed Scout equipped with pontoons for water landings. On September 11, 1913, Lahm attempted a water takeoff for a flight test but the center of gravity on the aircraft made it tail-heavy and it flipped over. Although the aircraft was totally destroyed, Lahm was saved from drowning by a life jacket.

This is the first documented fatality of a member of the 37th since it was formed. Unfortunately at the time detailed records were not kept of sappers killed in action and whilst his name almost certainly can be found on the South African Memorial Arch (Boer War) in Chatham which name is his is still not known. For the rest of the campaign, the 37th Field Company continued to be deployed on tasks with the Fifth Infantry Division, mainly building ramps for pontoons, dismantling bridges to be reused, or building roads for naval guns to be moved along. By 4 July 1891 they were halted at Volksrust having crossed the Drakensbergand were employed in constructing defences, and in repairing the railway line to Standerton.

If the pontoon vessel tips, it will remain stable as long as the center of gravity does not move further to the side than the center of buoyancy is moved by the change in the depth (and displacement) of each pontoon. Under these conditions a "righting force" (a turning moment) acts on the vessel to push it back toward the level position. However, if the center of gravity is high relative to the width of the vessel, and the pontoons on one side are unable to bear the vessel's complete weight, the lateral movement of the center of buoyancy will be restricted. Even a relatively small lateral force can move the center of gravity further to the side than the center of buoyancy can go.

Builders trials before her pre- commissioning cruise were done in Lake Huron. After completion, Carpellotti sailed from the builder's yard at Bay City to Chicago, Illinois. From there, she went through the Chicago Sanitary and Ship Canal and down the Chicago River to Joliet, Illinois, where pontoons were attached to the ship so it could be pushed down the Des Plaines River, Illinois River, and Mississippi River as part of a barge train. After arriving at the Todd Johnson Shipyard in Algiers, Louisiana, on the west bank of the Mississippi at New Orleans, the rest of the crew reported aboard, and Carpellotti was commissioned at New Orleans on 30 July 1945, with Lieutenant Commander J. V. Brown, USNR, in command.

They were replaced with a Maule M-4, but also this was retired after two years.Hagby: 194 Instead Mørefly shifted focus to the helicopter market. The first helicopter, a Bell 47G4, was bought in 1966. It was supplemented with a -J2 variant on pontoons the following year. A Bell 206 A1 Jet Ranger was procured in 1968 and was intended for search and rescue and cargo flights. From 1969 the airline's only fixed-wing aircraft was a Cessna 206.Hagby: 219 Mørefly continued to purchase helicopters, including a Bell 204B in 1972. A Piper PA-31 Navajo was bought in 1976 and kept for ten years.Hagby: 231 During the mid-1970s Mørefly established two joint ventures at Bergen Airport, Flesland.

The beetle pontoons were used to hold up the 'Whale' roadway sections, with four of the whales being built at Cairnryan. With easy access to the North Atlantic, Loch Ryan was used as the surrender destination for the U-boats which were out in the Atlantic in 1945 when hostilities ceased. The U-boats and their crews were held at Cairnryan, before the boats were finally towed out into the Atlantic and sunk. Other wartime activity on the loch included construction of target rafts made out of wood and cork, which were built in Stranraer then floated out the Loch and round the Rhins of Galloway to their positions in Luce Bay for bombing practice (operating out of West Freugh).

In 1925, Falcon joined the Control Force for operations in the Panama Canal Zone, along the U.S. West Coast, and in the Hawaiian Islands. She returned to home waters in September, and began her part in the salvage operations on in which she joined that fall and the next spring. After the submarine was raised through determined and ingenious efforts, it was Falcon who towed her to New York in July 1926, providing air pressure for the pontoons supporting the submarine, as well as her compartments. Acting as tender as well as salvage ship for submarines, Falcon accompanied them to fleet exercises in waters from Maine to the Panama Canal Zone, and conducted many operations to develop rescue techniques, as well as training divers.

She, in turn, was replenished by another LST that came up river from the port of Vũng Tàu. A good deal of activity took place during that period of both base and ship defense; 15 to 20 rounds of 3-inch (76.2-millimeter gunfire were fired nightly for harassment and interdiction; all gun mounts were manned continuously throughout the nocturnal hours, to be fired while the crew was proceeding to their general quarters stations. In addition, six sentries patrolled the pontoons moored alongside, and on the main deck; boats patrolled 150 to 200 yards (137 to 183 meters) away, remaining alert for possible swimmers, naval mines, or traffic of a suspicious nature. Periodically, percussion grenades were tossed into the water as anti-swimmer measures.

In 1924, Julian, along with Chamberlin, began toying with the idea of performing a transatlantic flight, with stops in Florida, the West Indies, Central America, Brazil, and Saint Paul's Rock (in the mid-Atlantic), from New York City to Liberia. An old seaplane was purchased and refitted for the proposed flight; Julian dubbed it the Ethiopia. On 4 July, with a crowd of thousands gathered at the banks of the Harlem River to witness his takeoff, Julian boarded his plane, after having UNIA members help raise some last-minute funds to pay off his investors, and soared into the sky. A few minutes would pass before Julian realized that one of his plane's pontoons had filled up with water, throwing the aircraft's weight off balance.

During the Peninsular War the British army transported "tin pontoons" that were lightweight and could be quickly turned into a floating bridge. Lt Col Charles Pasley of the Royal School of Military Engineering at Chatham England developed a new form of pontoon which was adopted in 1817 by the British Army. Each pontoon was split into two halves, and the two pointed ends could be connected together in locations with tidal flow. Each half was enclosed, reducing the risk of swamping, and the sections bore multiple lashing points. The "Palsey Pontoon" lasted until 1836 when it was replaced by the "Blanshard Pontoon" which comprised tin cylinders 3 feet wide and 22 feet long, placed 11 feet apart, making the pontoon very buoyant.

The EFA system was first deployed by the French Army in 1965, and subsequently by the West German Bundeswehr, British Army, and on a very limited basis by the U.S. Army, where it was referred to as Amphibious River Crossing Equipment (ARCE). Production ended in 1973. The EFA was used in combat by the Israel Defense Forces (IDF), which employed former U.S. Army equipment to cross the Suez Canal in their counterattack into Egypt during the Yom Kippur War of 1973. Mobile Floating Assault Bridge 1982 EWK further developed the EFA system into the M2 "Alligator" Amphibious Bridging Vehicle equipped with fold-out aluminum flotation pontoons, which was produced from 1967 to 1970 and sold to the West German, British and Singapore militaries.

In preparation for World War II, the Brooklyn Navy Yard was extensively reconstructed. The Navy Yard was expanded slightly to the west by , bringing its total area to , and parts of the mid-19th-century street grid were eliminated in favor of new developments. These structures included the construction of an , single-story turret-and-erection shop; the expansion of the Connecticut building ways; and lengthening of Dry Dock 4. By 1939, the yard contained more than of paved streets, four drydocks ranging in length from , two steel shipways, and six pontoons and cylindrical floats for salvage work, barracks for marines, a power plant, a large radio station, and a railroad spur, as well as foundries, machine shops, and warehouses.

Condé advanced to meet them. In the battle that ensued, Condé provoked the Spanish into giving up a strong hilltop position for an open plain, where he used the discipline and superior close-combat capabilities of his cavalry to charge and rout the Walloon-Lorrainer cavalry on the Spanish wings. The French infantry and cavalry in the center were attacked by the strong Spanish center, suffering heavy losses but holding their ground. The French cavalry on the wings, freed from any opposition, encircled and charged the Spanish center, who promptly capitulated. The Spanish lost half their army, some 8,000–9,000 men of which 3,000 were killed or wounded and 5,000–6,000 captured, 38 guns, 100 flags along with their pontoons and baggage.

Pontoons were the second product to be manufactured by the company. Again, wood was also used in the construction and even preservatives to protect them, prolonged exposure to water caused the wood to deteriorate quickly. Despite the clear advantages, there was initially a strong resistance to using materials that rusted easily but this changed with the widespread introduction of a new aluminum alloy developed at Zeppelin. Duralumin may have been the greatest metallurgical advance of its time and allowed aluminum to be used for structural members for the first time, normally being too soft in its pure form, while still being lighter than steel and very resistant to the types of corrosion that would compromise the strength of iron and steel alloys.

After shakedown, LST-1079 loaded pontoons and cargo at Davisville, Rhode Island, embarked Marines and took aboard ammunition at New York, and sailed 7 July 1945, for the Canal Zone. She arrived at Coco Solo 16 July, and then proceeded to Pearl Harbor where she was lying at anchor in West Loch when the war ended. On 21 August, she sailed for Guam via Eniwetok and off loaded cargo and passengers on arrival, sailing again 22 September, for Leyte. From Leyte she went to Subic Bay and then returned to Guam 6 November, to embark troops for "Magic Carpet" passage to San Francisco. She arrived San Francisco 28 December, was assigned to the 19th Fleet and subsequently made preparations for inactivation.

Seeing plasm as the key to humanity's liberation, he enlists the help of Rohder, one of Aiah's old colleagues from the Plasm Authority in Jaspeer (and a minor character in Metropolitan). A centuries-old researcher-mage, Rohder had discovered new geometric properties that could boost the production of plasm in cities, with the unfortunate need to completely reorder their infrastructure at prohibitive cost. Fortunately, Caraqui is a metropolis built on pontoons in the shallows of one of the world's seas, so Constantine enables him to experiment by physically moving parts of the city in concordance with his theory, which proves valid. Aiah also stumbles onto the knowledge that at periodic intervals, a small hole opens up in the Shield through which plasm- based constructs can be sent.

Subsequently the term pontoon fender took on another more prominent definition, derived from the wartime practice in Germany of adding full-length tread armor along each side of a tank, attached primarily on the top edge—and resembling pontoons. As this roughly coincided with automobile styling trend where distinct running boards and articulated fenders became less common — with cars carrying integrated front fenders and full-width, full-length bodywork — the fenders took on the "pontoon fender" nickname. The postwar trend of the markedly round, slab-sided designs became itself known as ponton styling—with many postwar Mercedes-Benz models informally nicknamed the "Ponton". The British assumed the latter definition, using it in such works as the Beaulieu National Motor Museum Encyclopedia of the Automobile.

From the beginning, the construction program was plagued by difficulties which caused it to fall far behind schedule. Unfamiliar with the capabilities of the Great Lakes yards, Kaiser Cargo used prefabrication techniques unsuited to the Great Lakes yards smaller cranes and had to rework them. Ice prevented patrol frigates built on the Great Lakes from transiting the Soo Locks on the St. Marys River between Lake Superior and Lake Michigan, in the winter and spring, requiring them to be floated down the Mississippi River on pontoons to New Orleans or Houston, for fitting out, often doubling their construction time. Delays became so lengthy that shipyards began to deliver the ships in such an incomplete state that shakedown and post-shakedown periods of repair and alteration took months for some of them.

Ambrose Burnside succeeded McClellan and appointed Comstock the chief engineer of the Army of the Potomac. During the Fredericksburg Campaign, Comstock was faced with the difficult task of constructing pontoon bridges over the Rappahannock River, a debacle which proved to be one of the most challenging of his career. Due to confusion in Washington, D.C. at the War Department, the materials necessary for the construction of the bridges did not arrive at Falmouth, Virginia at the same time as the Army of the Potomac. Despite Comstock's urgent telegraphs and messages, which went unanswered, it took nearly a month for the pontoons to arrive during which time the Union army had completely lost the element of surprise, the Confederate army had dug in at Fredericksburg, Virginia and morale within the Army of the Potomac had sunk.

Negotiations with the Belgian colonial authorities in the Belgian Congo produced an agreement for Northern Rhodesia to build and maintain a 70-km graded laterite road from Mokambo (16 km from the Copperbelt town of Mufulira) to Chembe. Although only used by Northern Rhodesia and with no Congolese settlements except Mokambo on its route, it had border control posts at both ends and traffic drove on the right. By the 1950s the Chembe Ferry had two motorised pontoons able to take the largest trucks, the border posts worked smoothly and the 174-km drive from Mufulira to Mansa could be completed in four or five hours. By comparison the same journey keeping to roads within the country was 1166 km and took at least two days, going via Kapiri Mposhi, Mpika, Kasama and Luwingu.

On Saturday, November 24, workers noticed that the bridge was about to sink, and started pumping out some of the pontoons; on Sunday, November 25, a section of the bridge sank, dumping the contaminated water into the lake along with tons of bridge material. It sank when one pontoon filled and dragged the rest down, because they were cabled together and there was no way to separate the sections under load. No one was hurt or killed, since the bridge was closed for renovation and the sinking took All of the sinking was captured on film and shown on live TV. The cost of the disaster was $69 million in damages. A dozen anchoring cables for the new Hadley bridge were and it was closed for a short time afterward.

Divers would descend to each wreck and perform work such as closing and dogging bulkhead hatches and fastening timber backed plate-steel patches over holes.. Then air would be pumped in from air compressors at the surface. In some cases where the hulls themselves could not be made close enough to air- tight, pontoons were used, similarly being filled with air, and ballast was sunk alongside the sunken ships and then secured to them to counterbalance them for lifting. It was during this stage of the project that his venture suffered a severe blow; the price of scrap metal collapsed, finally stabilising at a quarter of its previous value. Whilst sufficient profit remained to ensure a chance of breaking even, the sunken fleet no longer represented the cash rich harvest that it once had.

When in the area in 1933, he had found that the sea-walls were partially covered in a fine green seaweed, which the tanks might not have been able to scale. In 1996, Prior and Wilson wrote that the amphibious part of the plan was extremely risky, given the slow speed of the monitors and un-armoured pontoons. A German mobile force was on hand as a precaution and the area could be flooded. In 1997, A. Wiest called the plan an imaginative way to return to a war of movement, foreshadowing the amphibious warfare of World War II and a credit to Haig but his refusal to agree to a landing independent of events at Ypres, showed that he had overestimated the possibility of a German collapse.

Later, as a nation and empire that came to control all of the Fertile Crescent, Egypt and much of Anatolia, the term "Assyria proper" referred to roughly the northern half of Mesopotamia (the southern half being Babylonia), with Nineveh as its capital. The Assyrian kings controlled a large kingdom at three different times in history. These are called the Old (20th to 15th centuries BC), Middle (15th to 10th centuries BC), and Neo-Assyrian (911–612 BC) kingdoms, or periods, of which the last is the most well known and best documented. Assyrians invented excavation to undermine city walls, battering rams to knock down gates, as well as the concept of a corps of engineers, who bridged rivers with pontoons or provided soldiers with inflatable skins for swimming.

The noted engineer Isambard Kingdom Brunel, a professional rival and personal friend of Stephenson's, was claimed to have remarked to him: "If your bridge succeeds, then mine have all been magnificent failures". On 20 June 1849, Brunel and Stephenson had both looked on as the first of the bridge's tubes was floated out on its pontoons. The construction techniques employed on the Britannia Bridge had obviously influenced Brunel as he later made use of the same method of floating bridge sections during the construction of the Royal Albert Bridge across the River Tamar at Saltash. There was originally a railway station located on the east side of the bridge at the entrance to the tunnel, run by the Chester and Holyhead Railway company, which served local rail traffic in both directions.

The Wilhelmina dock would be constructed at a special terrain that the NSM had leased. This terrain was connected to the former shipyard Gebroeders van Lindern, which also exploited the Koningsdok that lay just west of it. The temporary terrain of the NSM was designated as 'next to the Koningsdok'. This terrain would later become the location of the ADM, and currently houses the EYE Film Institute Netherlands. On 25 September 1898 the first pontoon was launched. It measured 29.25 m by 21.36 m, had a hold of 3.32 m, weighed 440,000 kg and could lift 1,250,000 kg. Therefore the six pontoons could lift 7,500,000 kg in total. The dock had four 18 inch centrifugal pumps each with their own compound steam engine and each with a capacity of 2,000 tons an hour.

Moore is the founder of the Algalita Marine Research and Education in Long Beach, California, and currently works there. In 2008 the Foundation organized the JUNK Raft project, to "creatively raise awareness about plastic debris and pollution in the ocean", and specifically the Great Pacific Garbage Patch trapped in the North Pacific Gyre, by sailing 2,600 miles across the Pacific Ocean on a raft made from an old Cessna 310 aircraft fuselage and six pontoons filled with 15,000 old plastic bottles. Crewed by Dr. Marcus Eriksen of the Foundation, and film-maker Joel Paschal, the raft set off from Long Beach, California on 1 June 2008, arriving in Honolulu, Hawaii on 28 August 2008. On the way, they gave valuable water supplies to Ocean rower Roz Savage, also on an environmental awareness voyage.

Near the end of the war on April 22, 1945 at 2pm a Mitsubishi A6M Zero two seater plane piloted by Shimbo and Ensign Chuhei Okubo in the second seat, overflew Seeadler Harbor at 14,000 feet. They saw what they thought were two "aircraft carriers", but here actually empty floating dry docks ABSD-4 and ABSD-2. On April 27, 1945 at about 11:15pm a three Nakajima B5N a Japanese Zero fighter aircraft of the Imperial Japanese Navy flying from Truk flew over ABSD-4, one plane dropped an aerial torpedo and it hit one of the pontoons tanks of ABSD-4 damaging the dry dock. At the time of the attacked ABSD-4 was repairing a cargo ship, Landing Ship, Tank (LST) ship and a seaplane tender ship.

There, what became known as the 'Repository Grounds' were laid out with trees, ditches, ravines, earthworks, and other structures in order to train troops in the movement of guns, ammunition and heavy equipment across difficult terrain. There were two large ponds, on which men were taught 'to lay pontoons, to transport artillery upon rafts, and all the different methods that can be adopted for the passage of troops across rivers, &c.;'. In the 1820s an earthwork training fortification was added along the length of the eastern boundary, on which were mounted 'all the different sorts of cannon used in the defence of fortified towns'. On the southern part of the site, four long gun-carriage sheds were built in 1802-5 (the northernmost, with offices at either end, designed to accommodate items from the Repository's historic collection).

First the relatively small destroyers were winched to the surface using pontoons and floating docks to be sold for scrap to help finance the operation, then the bigger battleships and battlecruisers were lifted, by sealing the multiple holes in the wrecks, and welding to the hulls long steel tubes which protruded above the water, for use as airlocks. In this fashion the submerged hulls were made into air-tight chambers and raised with compressed air, still inverted, back to the surface. Cox endured bad luck and frequent fierce storms which often ruined his work, swamping and re-sinking ships which had just been raised. At one stage, during the General Strike of 1926, the salvage operation was about to grind to a halt due to a lack of coal to feed the many boilers for the water pumps and generators.

The launch took place from a pontoon submerged more than 30 metres deep in the sea off the Visakhapatnam coast. After a powerful gas generator ejected it from the pontoon submerged in the Bay of Bengal, the K-4 missile rose into the air, took a turn towards the designated target, sped across 3,000 km in the sky and dropped into the Indian Ocean. , the missile was planned for further testing both from pontoons and submarines before being declared operational.India’s Nuclear Triad Finally Coming of Age It is reported that on 7 March 2016 the K-4 was successfully tested from a submerged platform in the Bay of Bengal. In April 2016, it was reported that the missile was successfully tested on 31 March 2016 from INS Arihant, 45 nautical miles away from Vishakhapatnam coast in Andhra Pradesh.

A plan was devised to land British heavy tanks from pontoons in support of the Third Battle of Ypres, but this was abandoned.Fletcher, D British Mark IV tank New Vanguard, Osprey Publishing Landing at Cape Helles, at Gallipoli The lessons of the Gallipoli campaign had a significant impact upon the development of amphibious operational planning, and have since been studied by military planners prior to operations such as the Normandy Landings in 1944 and during the Falklands War in 1982. The campaign also influenced US Marine Corps amphibious operations during the Pacific War, and continues to influence US amphibious doctrine. During the interwar period the campaign "became a focal point for the study of amphibious warfare" in the United Kingdom and United States, because it involved the four types of amphibious operations: the raid, demonstration, assault and withdrawal.

The United States Court of Appeals for the Eleventh Circuit affirmed the lower court and Lozman filed a petition for a writ of certiorari with the United States Supreme Court. Lozman gained his first Supreme Court victory, when the Court reversed the Eleventh Circuit in a landmark admiralty opinion, ruling that floating structures are not subject to federal jurisdiction. Writing for the 7-2 majority, Justice Stephen G. Breyer stated: "Not every floating structure is a 'vessel.’ To state the obvious, a wooden washtub, a plastic dishpan, a swimming platform on pontoons, a large fishing net, a door taken off its hinges, or Pinocchio (when inside the whale) are not 'vessels,' even if they are 'artificial contrivances' capable of floating, moving under tow, and incidentally carrying even a fair-sized item or two when they do so".

The Ottawa Rowing Club was founded on 6 June 1867,Ottawa Times, 6 June 1867.. One of its founders and first patron was Sir John A. Macdonald; other members of the first executive committee included Robert Lyon (politician), mayor of Ottawa, and; Allan Gilmour, businessman in the shipping and timber industries. The original club house was a wooden building, initially built on pontoons, and moored to the shore of the Ottawa river at the foot of parliament hill, between the Rideau canal and the Chaudière falls. Whilst the view from the club house over the Chaudière falls was picturesque, the rowing conditions were difficult: vast field of sawdust and other refuse from an immense lumber mill situated about the falls, and logs escaping from the booms. Each spring, along with the melting ice, the club house floated downstream and came aground.

In 1912 Stone entered a partnership with Ernest J. Siddeley, in which Stone was the driving design force while Siddeley was the project manager who executed the works. Edward Giles Stone adopted the Considère system for reinforcing concrete and the partnership produced some remarkable buildings and structures using this system, notably the Dennys Lascelles Austin wool store at Geelong, the Barwon Sewerage Aqueduct, Floating Pontoons at Circular Quay and the Breakwater at Glenelg.See also the article in the Commonwealth Engineer Stone and his partner Siddeley designed and constructed the concrete structures on the Mortlake Gas Works in Sydney including the coal and coke bunkers, the tunnel to take the Telpher system under the retorts, as well as the Power House. Stone is seen as an important early user of reinforced concrete of interest due to his use of the Considère system.

Late on the evening of 21 January, Durnford was ordered to Isandlwana, as was a small detachment of No. 5 Field Company, Royal Engineers, commanded by Lieutenant John Chard, which had arrived on the 19th to repair the pontoons which bridged the Buffalo. Chard rode ahead of his detachment to Isandlwana on the morning of 22 January to clarify his orders, but was sent back to Rorke's Drift with only his wagon and its driver to construct defensive positions for the expected reinforcement company, passing Durnford's column en route in the opposite direction. Around 10:30am on the morning of 22 January, Durnford arrived from Rorke's Drift with five troops of the Natal Native horse and a rocket battery. A Royal Engineer, Durnford was superior in rank to Brevet Lt-Col Henry Pulleine, who had been left in control of the camp.

On 30 June 1898, Wompatuck joined the gunboats and in reconnoitering the port of Manzanillo, Cuba. They encountered the Spanish 30-displacement ton gunboat Centinela near Niguero Bay; Wompatuck′s draft was too great for her to pursue Centinela as she retreated into shallow water near the coast, but Hist and Hornet followed her and, after they exchanged fire with Centinela and with Spanish troops on shore, Centinela′s crew beached her. The three American ships then proceeded to Manzanillo itself, where they found numerous merchant ships and six Spanish warships, the gunboats Cuba Española, Delgado Parejo, Estrella, Guantánamo, and Guardián and the sailing vessel Maria; Cuba Española, Guardián, and Maria were functioning as immobile armed pontoons. Second in column, Wompatuck followed Hist′s lead and opened fire on the Spanish ships as soon as she reached firing range.

119 The capsizing of the battleship Novorossiysk in Sevastopol harbor on 29 October 1955 delayed salvage operations on Stalingrad until the end of the year. The hull had to be patched, the water pumped out and all the projections removed to raise the stern slightly with pontoons, pivot into deeper water, then trim it down to elevate the bow off the bottom and pull it free. These preparations were very time-consuming and it wasn't until mid-July 1956 that it could be pulled off the rocks into Sevastopol harbor where she was given more permanent repairs. She was then moved to the Naval Firing Range between Yevpatoria and Sevastopol where it was used as a target for seven P-1 or KSS anti-ship missiles fired from the converted Sverdlov-class cruiser Admiral Nakhimov in December 1956.

Tourism became increasingly important as the growing national affluence, and especially the 1961 opening of the Hood Canal Bridge that cut driving time from the populated central Puget Sound region, brought more visitors drawn by the mountains, rivers, and rainforest of Olympic National Park and by fishing and boating along the Strait of Juan de Fuca. The mills began to close in the 70s and 80s until only one pulp mill remained in operation. In August, 2003, a $275 million construction project known as the Graving Dock Project was started in Port Angeles near the water as part of the Hood Canal Bridge east- half replacement project. It was intended to construct an area for anchoring pontoons for the bridge.Review of Port Angeles Graving Dock Project , Report 06-8, June 30, 2006 During construction, human remains and artifacts were discovered.

Trewavas was 19 years old, and a seaman in the Royal Navy during the Crimean War when the following deed took place for which he was awarded the VC. On 3 July 1855 in the Strait of Genitchi, Sea of Azov in the Crimea, Seaman Trewavas of HMS Beagle was sent in a 4-oared gig to destroy a bridge, and so cut the Russians' main supply route. This was the third attempt, the first two having failed. As the gig ground against the bridge, Seaman Trewavas leapt out with an axe and began to hew away at the hawsers holding the pontoons together, and although the enemy kept up a heavy fire, particularly on Trewavas himself, he continued until his task was completed, and the two severed ends of the pontoon began to drift apart. He was wounded as he got back into the gig.

In the center, mounted on a pyramid-shaped truss-work, were two end-to-end surplus aircraft engines. This vessel was dubbed the kleine fähre (small ferry) and initial testing was conducted on Rangsdorfer See, a lake near Berlin.Ansel, p.209 Chief of the Army General Staff General Franz Halder and a party of other Army officers were invited to witness one of these tests, but they were unimpressed by the ferry's performance. It could only make 4 knots and seemed overly flimsy. Halder noted “Nothing new, may not stand up in surf.” Others in the party questioned whether transported soldiers would arrive in fighting condition. Despite the Army's misgivings, Siebel continued working on modifying the ferry's design, reducing the initial spacing between the pontoons to , and requesting from Krupp-Rheinhausen (with assistance from WasserPrüfung 5) construction of a large steel platform covered with wood planking.

The Aerodrome was removed from exhibit at the Smithsonian and prepared for flight at Keuka Lake, New York. Curtiss called the preparations "restoration" claiming that the only addition to the design was pontoons to support testing on the lake but critics including patent attorney Griffith Brewer called them alterations of the original design. Curtiss flew the modified Aerodrome, hopping a few feet off the surface of the lake for no more than 5 seconds at a time. Between 1916 and 1928 the Wright Flyer was prepared and assembled for exhibition under the supervision of Orville by Wright Company mechanic Jim Jacobs several times. It was briefly exhibited at the Massachusetts Institute of Technology in 1916, the New York Aero Shows in 1917 and 1919, a Society of Automotive Engineers meeting in Dayton, Ohio in 1918, and the National Air Races in Dayton in 1924.

After an attempt by the rescue tug Merkury to pump out the flooded compartments, Sovershenny was towed into the shallows of Kazachya bay for the night due to fears of her sinking from loss of reserve buoyancy. On the next morning, pontoons were placed under the hull and she was towed back to Sevastopol, being placed in a floating dock to patch the hole in her hull on 2 October. The destroyer was subsequently transferred to the drydock of Shipyard No. 201.Platonov, p. 219, Yakubov & Worth, p. 113 A 130 mm gun from Sovershenny used by a battery on Malakhov Kurgan During an attack by German aircraft on 12 November, the destroyer was struck by two bombs during a raid by Heinkel He 111s of the First Group of Kampfgeschwader 27 (I./KG 27) and Junkers Ju 88s of KG 51.Forczyk, pp.

However, purely as a precautionary measure, Lee does agree to send a pontoon train that was captured from the Union army during the Gettysburg Campaign westward to the vicinity of Frederick, Maryland, where it would be in better position to assist in any rapid Confederate movements in that direction. General George Armstrong Custer in command of a Union cavalry brigade screening Couch's force learns of Lee's movement of the pontoon train from a loyal Union railroad man, and decides it is an important enough prize that he must abandon his current mission, leaving Couch without proper screening forces. As a result, Lee quickly learns that, as suspected, Couch's force is a feint and of no military concern, and, also, that Custer is moving on Frederick. While the pontoons are not of critical importance, Lee realizes that the town of Frederick itself is extremely critical.

The original Evergreen Point Floating Bridge, also named for state governor Albert D. Rosellini, opened on August 28, 1963, carrying the four-lane State Route 520 (at the time designated temporarily as the Evergreen Point branch of Primary State Highway 1 until the 1964 state highway renumbering). The floating span consisted of 33 pontoons and cost $24.7 million to construct (equivalent to $ in ); the bridge carried four lanes of traffic, separated by a curb that was later replaced with a simple Jersey barrier; at the center was a drawspan that opened for large vessels traversing the lake. The original bridge would also close to traffic during sustained wind gusts of or higher for more than 15 minutes. Due to increased traffic generated by rapid growth of the Eastside area, bridge replacement was explored as early as 1969, when building a parallel span was explored and rejected.

For instance, there is a long- lived story that, back in the 1970s, if all seven draglines at Peak Downs Mine (a very large BHP coal mine in central Queensland, Australia) turned simultaneously, they would black out all of North Queensland. However even now, if they have been shut down, they are always restarted one at a time due to the immense power requirements of startup. "Walking" dragline animation based on Martinson's patent of 1926 In all but the smallest of draglines, movement is accomplished by "walking" using feet or pontoons, as caterpillar tracks place too much pressure on the ground, and have great difficulty under the immense weight of the dragline. Maximum speed is only at most a few metres per minute,"Maid Marian's journey becomes a 'drag'" The Daily Gleaner (10 October 2008) accessed 1 November 2008] since the feet must be repositioned for each step.

The heavy steel bridges could be transported from a Base Park at Le Havre with notice. A bridge over the canal near Péronne was built by surveying the ground on the night of 15 March, towing pontoons up river the next night, building beginning at dawn on 17 March and the pontoon being ready by noon. Infantry of the 1/8th Royal Warwicks crossed that evening and were then ferried over the river beyond on rafts, to become the first Allied troops into Péronne. On the right flank, IV Corps had to advance about over cratered and blocked roads to reach the Somme but Corps Mounted Troops and cyclists arrived on 18 March to find German rearguards also mounted on bicycles. Infantry crossed the river on 20 March by when the mounted troops had reached Germaine and the Fourth Army infantry outposts were established on high ground east of the Somme.

In 1258, the Naviglio Grande reached Milan. New taxes were levied to continue the digging, and although the work stopped again following opposition from the citizens and clergy, the whole canal was navigable from 1272, when the deepening and widening of the canal bed was completed by Giacomo Arribotti and the canal reached the bridge of Sant'Eustorgio (now Porta Ticinese). Although intended mostly for irrigation, pontoons called cobbie quickly began using the canal to take salt, grain, wine, manufactured goods, fabric, tableware, manure and ash upriver to Lake Maggiore and Switzerland, bringing back livestock, cheese, hay, coal, lumber, sand, marble and granite. The small lake of Sant'Eustorgio was linked to the Fossa Interna (also known as the Cerchia Interna or Inner Ring) of Milan using a new system of two locks to control the water level, thereby allowing boats to reach Piazza Santo Stefano.

The landing ship again served as primary control ship (PCS) in Da Nang harbor during Operation Gallant Leader, a follow-up to Operation Daring Rebel. Relieved by Duluth on 23 May, Tortuga set sail soon thereafter for Buckner Bay and simulated combat landings during exercises with Assault Craft Unit 1 in late June. In July, Tortuga transported the first increment of Marines and their equipment for Operation Keystone Eagle, from Cửa Việt Base, South Vietnam, to White Beach, Okinawa, before returning up the Saigon River to Nha Be with a load of palletized cargo. Subsequently supporting Operation Sea Float, delivering two pontoons and 32 pallets of ammunition from Nhà Bè to Tân Mỹ Base, Tortuga onloaded men and equipment from "Charlie" Battery, 1st Light Antiaircraft Missile Battalion (LAAM), 1st Marine Aircraft Wing, at Da Nang harbor for transport to the west coast of the United States.

German General Staff, (1998), p. 78 Substantial British reinforcements (an army corps under General Redvers Buller) arrived in South Africa and were dispersed to three main fronts. While Buller himself advanced from the port of Durban in Natal to relieve the besieged town of Ladysmith and a smaller detachment under Lieutenant General Gatacre secured the Cape Midlands, the reinforced 1st Division under Lord Methuen advanced from the Orange River to relieve Kimberley.German General Staff, (1998), p. 79 alt=A low bridge over twelve pontoons, with troops on the nearby bank Methuen advanced along the Cape–Transvaal railway line because a lack of water and pack animals made the reliable railway an obvious choice. Also, Buller had given him orders to evacuate the civilians in Kimberley and the railway was the only means of mass transport available.Miller, (1996) But his strategy had the disadvantage of making the direction of his approach obvious.

The Sherman DD could not fire when afloat as the buoyancy screen was higher than the gun. A number swamped and sank in the operation, due to rough weather in the English Channel (with some tanks having been launched too far out), and to turning in the current to converge on a specific point on the battlefield, which allowed waves to breach over the screens. Those making it ashore, however, provided essential fire support in the first critical hours. Before World War II, The Soviets produced light amphibious tanks called T-37 and T-38. A third serial model, T-40, started production after the beginning of the war. A 14-ton tank, PT-1 was created but was not mass-produced. In addition, an attempt was made to attach pontoons to T-26. While successful, the project was closed due to the high vulnerability and unwieldiness of the construction.

Following Winston Churchill's famous memo 'Piers For Use On Beaches' dated 30 May 1942 the Mulberry project gained momentum under the direction of Major General D J McMullen and civil engineer Brigadier Bruce White. An early priority was the construction of trial installations in the Clyde estuary at Gare Loch. Hughes designed and supervised construction of a prototype jetty consisting of 'Hippo' concrete caissons sunk on the sea bed supporting 'Crocodile' steel roadway bridge units which spanned between the Hippos. The prototype was built at Conwy Morfa near Hughes' home town of Conwy and towed to Garlieston Wigtownshire in Scotland, where it was installed and tested against two other designs, both of which were floating roadways; the 'Swiss Roll' designed by R M Hamilton was made of canvas and steel cables, while the 'Whale' roadway designed by Allan Beckett consisted of flexible bridge spans mounted on pontoons.

Ordered to proceed to Bailey's Beach south of Scoglitti she discharged DUKWs before beaching. Both ramp chains parted while discharging DUKWs and a jury rig of wire pennants was installed. The Beachmaster advised that no pontoons were available. The vessel was beached on 11 July and the commanding officer went ashore to arrange for a causeway. While awaiting the causeway, then in use by another LST, several enemy aircraft attempted to attack the beach and the LST-16 opened fire. At 17:00, the causeway was received and all vehicles and Army were off by 19:00. The ship's company unloaded 470 tons of supplies by hand, completing the task by 14:00 on 12 July. At 17:00 she proceeded to a newly marked beach north of Scoglitti and on 13 July loaded 300 tons of ammunition and supplies from and proceeded to anchorage.

Norwegian nuclear safety expert Nils Bøhmer stated that such isotope composition proves a nuclear reactor was involved in the accident. On 2 September, Belomorkanal news agency published a video showcasing two abandoned pontoons near the mouth of where the Nyonoksa River empties into the Dvina Bay only 4 km from the center of Nyonoksa, with one of them carrying an array of heavily damaged testing equipment. According to Nyonoksa residents, the first pontoon "PP PP Plant No. 2" () with two blue containers washed ashore on 9 August and the heavily damaged second pontoon with a damaged crane, a blue container and a yellow container similar to a Siempelkamp container for highly radioactive materials was towed by tugboats to a site near the first pontoon about five days after the explosion. The video by Severodvinsk journalist Nikolai Karneyevich () demonstrates gamma radiation levels at from the abandoned vessels on the White Sea shore close to Nyonoksa with the reading reaching 186 μR/hour - 15 times higher than natural.

In 1912, the Short S.36 tractor biplane, built for Francis McClean, was loaned to the Royal Navy for use at its Naval Flying School. Impressed by the S.36, the Admiralty ordered two similar tractor biplanes, capable of operating on either wheels or floats, the smaller Short S.45, like the S.36, powered by a 70 hp (52 kW) Gnome Lambda, and the larger Short S.41 powered by a 14-cylinder, twin-row 100 hp (75 kW) Gnome double Omega rotary engine.Barnes 1967, pp. 79–80. The S.41 was an unequal-span two bay tractor biplane with a slim rectangular section fuselage mounted between the wings. It was first flown by Charles Rumney Samson on 2 April 1912 with a wheeled undercarriage, and shortly afterwards was fitted with floats, consisting of two main pontoons under the fuselage and smaller floats at the wingtips and tail, and was delivered to the Navy.Barnes 1967, p.80.

11 When the offensive began on April 16 the 15th Guards was to break through the German defense on a sector from Kobeln to the farm, help to eliminate a German bridgehead on the eastern bank in the Muskau area, then cross the Neisse under the cover of massed artillery fire and capture the northern part of Berg before advancing into the German rear. For this mission the 50th Guards Regiment was supported with a company of tanks, a platoon of self-propelled guns, a sapper company and two batteries from a separate antitank battalion. The 47th Guards Regiment had the same supporting forces less one antitank battery while the 44th Guards Regiment was in the second echelon with orders to assault across the Neisse behind either the 50th Regiment or in the sector of the 58th Guards Division, depending on circumstances. For the crossing the division had gathered 33 boats, two 16-tonne ferries and two 3.5-tonne captured pontoons.

Groundbreaking ceremony for East Link in Bellevue on April 22, 2016 Sound Transit broke ground on the project's downtown Bellevue tunnel on April 22, 2016, beginning its construction with the demolition of homes in the Surrey Downs area. The tunnel is being excavated using sequential mining, as opposed to tunnel boring machines used for Sound Transit's other light rail projects. To prepare for East Link construction on the express lanes of the Interstate 90 floating bridge, which began in June 2017, WSDOT added HOV lanes to the outer lanes of the freeway between Rainier Avenue in Seattle and Bellevue Way. The $283 million project was completed in stages from 2008 to 2012, reducing lane and shoulder widths on the floating bridge to accommodate the new lanes. The bridge's express lanes were closed to traffic on June 5, 2017, and will be rebuilt for light rail trains. Construction is scheduled to move from the pontoons to the bridge deck in 2019.

The river Weser In 1759, the fortified city of Minden, now the Innenstadt (inner city) of modern Minden, was situated at the confluence of the Weser, which flows from south to north, and the Bastau, a marshy tributary rivulette. The Bastau drains into the Weser from west to east, roughly parallel with, and south of, the western arm of modern Germany's Midland Canal, where it crosses the Weser at Minden, north of the Innenstadt via the second largest water bridge in Europe). The Battle of Minden took place on the plain immediately in front of the city and its fortifications, to its northwest, with the Weser and Bastau lying behind the city to its east and south respectively. On the 31st, the French troops under Contades' direct command had their positions west of the Weser and south of the Bastau, crossing to the north over five pontoons during the night and early morning of the 1st.

The JUNK Raft Project was organized by Dr. Marcus Eriksen, Joel Paschal and Anna Cummins in Long Beach, California in 2008, to bring attention to the issue of plastic pollution in the Great Pacific garbage patch. The project was launched with the Algalita Marine Research Foundation, after founder Charles J. Moore encountered the patch in 1997. Donovan Hohn (June 22, 2008), "Sea of Trash", New York Times Organizers hoped to "creatively raise awareness about plastic debris and pollution in the ocean," specifically the Great Pacific Garbage Patch trapped in the North Pacific Gyre, by sailing 2,600 miles across the Pacific Ocean on a raft made from an old Cessna 310 aircraft fuselage and six pontoons filled with 15,000 old plastic bottles. Crewed by Dr. Marcus Eriksen of the Foundation and film-maker Joel Paschal, the raft set off from Long Beach, California on 1 June 2008, arriving in Honolulu, Hawaii on 28 August 2008.

At on 23 August, in a thick fog, artillery batteries began to bombard Dinant. Most of the 40th Division was sent south to Givet and Fumay, thence to cross the Meuse and attack the right flank of the Fifth Army, which reduced the attack on Dinant to XII Corps. The 32nd Division (Major-General Horst von der Planitz) and the 23rd Reserve Division (Major-General Alexander von Larisch) crossed the Meuse on barges and pontoons at Leffe, north of the town and the 23rd Division (Major-General Karl von Lindemann) crossed to the south at Les Rivages. The French I Corps had been moved north-west to reinforce X Corps (General Gilbert Desforges) at Arsimont, having been relieved by the 51st Reserve Division ( René Boutegourd) and two brigades of the 2nd Division. Four columns of the German 46th Infantry Brigade of the 23rd Division advanced into Dinant, against a regiment of the 51st Reserve Division and Belgian irregulars (alleged).

When World War II broke out, Leonardi was the deputy commander of the La Spezia Arsenal. Later on, he became chief of staff of the Northern Adriatic Naval Department, and was promoted to Rear Admiral in 1942. In January 1943, following the Axis occupation of Vichy France, he became commander of the newly established Italian Naval Command in Toulon, as well as chief of staff of the Provence Naval Department. On 8 June 1943, Leonardi was appointed commander of the Augusta-Syracuse Naval Fortress Area. This was the most heavily armed fortress in Sicily, with six coastal batteries of large and medium caliber (381 mm, 254 mm, 152 mm), 17 anti-aircraft batteries (102 and 76 mm guns), two armed pontoons (armed with 149 and 190 mm guns) on the seaward side; like many fortresses and bases of the Regia Marina, however, whereas the seaward side was strongly fortified, the defences on the landward side were far weaker.

A large variety of different armoured combat vehicles were developed on the T-26 chassis in the 1930s. Among them were KhT-26, KhT-130 and KhT-133 flame-throwing (chemical) tanks (552, 401 and 269 vehicles were produced, respectively); T-26T artillery tractors (197 were produced); TT-26 and TU-26 remotely controlled tanks (162 teletanks of all models were produced); ST-26 bridge-laying tanks (71 were produced); SU-5 self-propelled guns (33 were produced); experimental armoured cargo/personnel carriers, reconnaissance vehicles, and many others. The majority of these vehicles were developed at the Leningrad Factory of Experimental Mechanical Engineering (from 1935 known as the Factory No. 185 named after S.M. Kirov) by talented Soviet engineers P.N. Syachentov, S.A. Ginzburg, L.S. Troyanov, N.V. Tseits, B.A. Andryhevich, M.P. Zigel and others. Various vehicle-mounted equipment was developed for the T-26, including mine- clearing attachments, inflatable pontoons and a snorkel system for fording water obstacles, devices for overcoming obstacles and many others.

The second stage consisted of commencing a long siege of Antwerp and constructing a bridge across the Scheldt, effectively closing off the city's waterways. The bridge, a unique feat of siege engineering at the time, consisted of a strong fort (reinforced with cannons) on each side of the Scheldt with a bridge of connected pontoons (paintings show sizable rowing boats) running between them. (This bridge is believed to have been 730m long.) In response to the closure of the Scheldt by this bridge, the Dutch flooded the lowlands adjacent to the Scheldt, effectively submerging most roads in scattered areas and leaving Spanish forts either flooded or isolated on small islands. Despite the Dutch using these floodplains to try to regain control over the Scheldt (using low draft oar and sail boats with small cannon emplacements on them), the Spanish position largely held firm, as many of the Spanish forts had been equipped with cannon and high quality troops.

The interior of the church The grave of Captain Protet who was buried standing up The plaque on Captain Protet's grave (died in 1836) Remnants of the former colonial presence (photo taken in 2008) Carabane has many historic sites, such as the Catholic mission house built in 1880 which has since been turned into a hotel, a Brittany-style church building which is no longer in use, and a former slave-trade building. There is also a French cemetery where a Troupes de marine-Captain with the name Aristide Protet was shot with a poisoned arrow and buried standing up in front of the sea, according to his last wishes. Some tour guides falsely claim that this was Auguste Léopold Protet, the founder of the city of Dakar, but the name Aristide Protet is clearly shown on the tomb's plaque. Near the beach are ruins of buildings, pontoons, and wells, with a large tree in the center.

Several Tiger II heavy tanks were also captured by the Soviet Union and were brought to Kubinka for further evaluations in 1944. In 1945 the Soviet Union also tested captured Japanese tanks that were seized after the rapid Soviet invasion of Manchuria, South Sakhalin, the Kuril Islands, northern China and northern Korea. (These include the Type 95 Ha-Go light tank, the Type 4 Ke-Nu light tank, the Type 2 Ka-Mi amphibious light tank (which has all of its pontoons and flotation devices fitted), and the Type 95 Ri-Ki crane vehicle (a combat engineering vehicle), amongst other types.) Besides captured Axis tanks and AFVs, the USSR also tested several Western Allied armour and military vehicles supplied to it under the auspices of the Lend-Lease military assistance program started by the United States. Such vehicles include the US M3 Stuart, M3 Lee/Grant, M4 Sherman, and also British ones, such as the Matilda II, Churchill and Valentine tanks.

NASA had partnered with Chrysler to build the NASA-designed Saturn IB, at the Michoud Assembly Facility outside New Orleans. Chrysler proposed building SERVs at Michoud as well, delivering them to KSC on the Bay- class ships used to deliver Boeing's S-IC from the same factory. Since the SERV was wider than the ships, it had to be carried slightly tilted in order to reduce its overall width. Pontoons were then added to the side of the ships to protect the spacecraft from spray.CR-150241, slide 9-11 SERVs would be fitted out in the Vehicle Assembly Building (VAB) High Bay, mated with the PM or MURP which were prepared in the Low Bay, and then transported to the LC39 pads on the existing crawler-transporters.CR-150241, slide 9-15 The LC39 pads required only minor modifications for SERV use, similar to those needed to launch the Saturn IB.CR-150241, slide 9-21 Chrysler proposed building several SERV landing pads between LC39 and the VAB, and a landing strip for the MURP near the existing Space Shuttle landing strip.

Joffre urged that it was "essential" that the BEF advance further. By 8 September, despite outnumbering the enemy by 10:1, the BEF had advanced just 40 km in three days.Herwig 2009, p252-4 On 9 September Sir John, arriving on the spot in person, ordered I Corps to halt as soon as they had reached the main road, a mere 5 miles from the river (at midday Haig, who had halted for four hours after crossing the river after seeing aerial reconnaissance of German forces opposite him, probably Ilsemann's 5th German Cavalry Division, not IX Corps baggage train as he believed, had just given orders to resume the advance). This prevented I Corps from taking Kraewel's detachment from the east flank, which would have helped II Corps, which had halted after encountering a mixed brigade at Montreuil-sur-Lions, and was now fighting uphill through woods. On the left Pulteney's engineers did not have enough pontoons to cross the Marne (70–90 metres wide), and by nightfall half of 4th Division's battalions crossed on a makeshift floating bridge.

The shield is blue for Infantry divided by a wavy fess of red, bordered by two gold bands, representing the Escaut River in Belgium, which the Regiment, under heavy fire, was the first of the Allied Troops to cross during World War I, costing the lives of many men, but held in the face of concentrated artillery fire and in the face of counterattacks. Two gold fleurs-de-lis, taken from the ancient French Arms denote service in France, the holding of two sectors in that country, the gold lion rampant is taken from the arms of Belgium and denotes service in that country in the Ypres-Lys offensive. At the time of the crossing of the Escaut River, the units attempting the act were just a little doubtful as to how a swift river could be crossed without pontoons. Lieutenant Colonel Marlin, then Major Marlin, reminded them of a certain ceremony that was to be performed on reaching the Rhine, and with the catch phrase "We'll Do It," the soldiers fell to work, cut down a tree across the Escaut and crossed, single file, over the tree.

US Coast Guard, part 1, part 2, Retrieved on September 7, 2009. equipped with pontoons for water landings and at once saw the advantages of helicopter- equipped search and rescue squadrons. Two early Sikorsky R-4s were acquired in 1941, and training was initiated at Coast Guard Station Brooklyn in New York. In 1942, Royal Air Force and Royal Navy fliers trained in Brooklyn after which the British bought a large number of "hoverflies" from Sikorsky to re-organize 705 Naval Air Squadron. The first hoist lift rescue occurred on November 29, 1945, when a barge ran aground at Penfield Reef, off Fairfield, Connecticut, during heavy weather, very near to the Sikorsky facility in Bridgeport. Sikorsky chief pilot Jimmy Viner, along with USAAF Captain Jack Beighle flew a Sikorsky R-5 (S-48) to lift the two crew members using the hoist and deposit them safely ashore. The first military helicopter air-sea rescue was carried out in 1946 when a Sikorsky S-51 being demonstrated to the U.S. Navy was used in an emergency to pull a downed Navy pilot from the ocean.McGowan, 2005, p. 65.

Stanlow Oil Refinery from the air The refinery occupies nearly near the River Mersey and dates back to 1924, when a small bitumen plant was established. Stanlow and Thornton railway station was opened in 1940 to give workers access to the site and the facility an extra mode of transport. However, this station is now only served by three trains daily towards each of Ellesmere Port (westbound) and Helsby (eastbound), with these services scheduled to depart at times which would be inconvenient for the workers. In the 1974 an oil pipeline was commissioned from Amlwch, Anglesey to Stanlow. Crude oil was pumped ashore from tankers moored at deep-water pontoons to a holding station at Rhosgoch, from there it was pumped through two 36-inch diameter pipelines, 127 km to Stanlow. The pipeline had closed by 1990. Crude oil is now received lower down river on the Mersey at the Tranmere Oil Terminal, operated by the Mersey Docks and Harbour Company from its Liverpool headquarters, and is transferred via a fifteen-mile (24 km) pipeline to storage at Stanlow. Output is delivered via various means, including by pipeline via the UK oil pipeline network, road and the Manchester Ship Canal.

Garland & Smyth, pp.154&155 As the Hermann Göring Division withdrew, the reserve force of the 2nd Armored Division and 18th Infantry Regiment began landing at 17:00 over the beaches being vacated by the 26th Infantry Regiment. LST-313 was attempting to offload anti-tank artillery when three or four fighters dropped bombs on the pontoon causeway being used to offload the LSTs. One bomb struck LST-313, killing 21 men, damaging embarked vehicles, and igniting a gasoline fire causing a series of ammunition explosions. The burning LST, with the 26th Infantry's anti-tank artillery,Atkinson (2007) p.100 was abandoned at 18:24; and continuing explosions scattered the pontoons, causing nearby LST-312 to broach, and prevented the offloading of more LSTs. The 1st Infantry Division requested extended air cover after being bombed from 17:30 to 19:30, and Axis bombing continued at a rate of 275-300 sorties per day with half arriving during hours of darkness. Gunfire support ships provided covering fire as the 1st Infantry Division began retreating back toward the beach at 21:50 under cover of darkness. Only three LSTs (carrying half-tracks but no tanks) had been unloaded when the 1st Infantry Division requested immediate tank support at 22:15.
