In order to meet the requirements for the vessel salvage and rescue industry, we have redesigned the launching airbags. These can now be used as pontoons for supporting docks and other floating structures, and they are also excellent for pipe-laying and other underwater construction projects to supply buoyancy. But the main application of the “Marine Salvage Airbags” is in shipwreck salvage, floating bridge and dock construction, rescue, and removal of wrecked ships and beached vessels.
Marine Salvage Airbags are very small in size when deflated, and are lightweight. Thus, they can be easily transported and deployed. They can be used vertically to right sunken vessels out of deep water. When the boat is suspended near the surface they can be slung under the boat with one end on each side to raise the boat high enough out of the water to pump it out. In shallow water two bags can be slung together like pontoons, one on each side of the boat. They can also be used as rollers for moving beached boats back into the water, just like our Ship Launching Airbags.
Our “Salvage Tubes” are made with special synthetic tire-cord layers, which have much better performance than those made with PVC coated fabrics.
Salvage Tubes have a maximum working pressure of 0.25Mpa. That means that they can be used under 25m water-depth.
Our “Vessel Salvage Airbags” are a totally enclosed tube with cone ends. It is manufactured using Holistic Screw technology. This design ensures that there aren’t any welded seams. This makes them stronger than RF welded salvage airbags.
Our Salvage-Bags are equipped with nylon straps and shackles with 6:1 safety factor

Air Bags for Ship Salvage
ISO 9001: 2000
Marine airbags are also known as launching bags, roller bags, air lift bags, and salvage bags. Standard air bag size range is 1.0m to 2.0m diameter, with lengths up to 18.0m ‘effective length’.
Airbags are used for ship salvage, launching, and floating. They are widely used in cargo boat launching and landing, lifting and moving sunken ships, and salvaging stranded boats. Air bags have the benefit of not only saving labor and time, but investment costs. Additionally they are flexible, portable, and dependable.
Pneumatic roller-bags relieve the restrictions of traditional slide-board technology which is commonly used in building small or medium size ships, and it provides an economical alternative to expensive dry docks.
Air bags also allow for the landing of vessels in locations previously restricted only to dry docks. Years of trial and error with pneumatic roller bag technology has increased the ability of launching from 100-ton ships up to 13,500-ton ships when using 8-layer bags.
4-layer bags that are 1.5m dia x 15m long contain a rubber content that is not less than 51%. The air-bags can safely hold 156-tons with a safe working pressure of 0.08MPa while rolling. When standing still the highest lifting pressure is 0.10MPa while holding 194-tons.
6-layer bags that are 1.5m dia x 15m long contain a rubber content that is not less than 51%. The air-bags can safely hold 234-tons with a safe working pressure of 0.12MPa while rolling. When standing still the highest lifting pressure is 0.14MPa while holding 272-tons.
