What Can Marine Salvage Airbags Do for You?

Marine salvage airbags have similar structures to ship launching airbags but feature some optimal designs for salvage and flotation applications taking advantage of stiff and lightweight structure, lifting belts and buckles. Rubber belts are usually used to fasten airbags together and buckles make the binding much easier. Safe valves, mounted to the ends of airbags, are ideal for releasing inner pressure automatically when marine salvage airbags are applied in deep water.

With the toughest pneumatic body, marine salvage airbags are generally used as temporary transportation device, or other applications such as shipwreck salvaging, floating bridges, dock construction, etc.

Ideal for supporting floating structures.

Serve as temporary transportation device.

Alternatives to rigid pontoon

Marine salvage airbags with high buoyancy form 10 tons to 50 tons per piece, are perfect for supporting docks, floating bridges and other floating structures with insufficient buoyancy or shortage of lifting capacity from barge crane. Meanwhile, they are the best choice for where traditional rigid pontoons are not applicable such as rescuing some capsizing vessels.

Drain function

Vessel cabins can be filled with marine salvage airbags to drive water out and restore buoyancy of vessels when airbags are inflated with air. Normally, maximum pressure of cabins and decks should be calculated before inserting airbags into cabins to check. . Sometimes, reinforcements should to be done to make sure that the deck and cabin can withstand the pressure from marine salvage airbags.

Jack stranded & sunken vessels up

For stranded vessels even more than 200 tons in weight, marine salvage airbags can be applied to jack them up and send them back to water without needs of dredging watercourse or using crane airbag. For sunken vessels, insert marine salvage airbags between the bottom or seabed of vessels, then fill them with air to increase buoyancy of sunken vessels and jack vessels up.

Caisson launching

In low water season, insufficient water level makes ship launching and caisson launching impossible. So buoyancy tanks and bags are needed. Our marine salvage airbags, not only can jack stranded or sunken vessels up, but also capable to provide a safe and smooth launch of vessels up to 5, 000 tons or caissons up to 8, 000 tons.


Not easy to be affected to wind and wave.

Less demand of binding.

Easy to meet the needs of buoyancy ranging from 100 tons to 2000 tons.

Easy to transport and store while the airbags are deflated.

Super- high tensile strength owing to its framework material - heavy- duty synthetic- tire- cord layers with breaking strength about more than 15, 000 N/ 5cm.

Excellent resistance against abrasion and scratch.

Low maintenance.

High flexibility and cost effectiveness.


With numerous combinations of diameters and lengths, marine salvage airbags have different buoyancy capacities as well as performances. Here is the buoyancy list of standard marine salvage airbags.

Lifting speed should be controlled about 1 meter per minute generally to make sure that airbags have enough time to vent expanding air by over- pressure valves.
