Detailed description
Florescence marine salvage inflatable rubber airbag
Marine Salvage airbag is the best choice for 100-2000 tons buoyancy need. Its good characters of easy transportation
and store, little demand of maintenance make the salvage works more flexible and cost-effective.
Salvage marine airbags can be inserted between vessel bottom and seabed to lift sunk vessel which can partly restore buoyancy of vessel itself. Each salvage marine airbag can lift more than 200 tons heavy under the water. For stranded vessel
salvage this heavy lift function is extremely useful.To send a stranded ships back to water marine airbag is the most
convenient tool. People can insert airbags to the bottom of vessel and then inflate them. With the pull of a tugboat or push of a bulldozer, ship can easily move into water with the roll of airbags.

In some big vessel salvage works, salvage marine airbags are often used to offer buoyancy to make up the shortage of
lifting capacity from barge crane. Salvage airbags can be attached to shipboard or stuff into cabins to offer buoyancy
assistance. People should control the lifting speed to allow airbags have enough time to vent expanding air by over-pressure valves. Generally the lifting speed is controlled at 1 meter per minute.
In some caisson launch projects salvage airbags have been proved to be very helpful. In the past when the water level at
launch way end is not deep enough people will have to build caisson for the second time after the caisson bases are launched. With marine salvage airbags people can add extra buoyancy to the launched caisson to ensure its safe floatation.
2.Standard specifications:
Diameter (D): | From 0.8m to 2.4m |
Effective Length (EL): | From 6.0m to 20.0m |
Total Length (TL): | From 7.0m to 21.5m |
Standard Number of Layers: | Usually 4-10 layers |
Loading Capacity: | About 10-40 T/M |
3.Application:
Ship launching marine airbags are used for ship launching, ship landing, ship lifting, loading, and floating. They are widely used in cargo boat launching and landing, lifting and moving sunken ships, and salvaging stranded boats. Marine airbags have the benefit of not only saving labor and time, but investment costs. Additionally they are flexible and dependable.
