Product Introduction:
Marine airbags can also be used for marine salvage airbags. Marine salvage and refloatation is another application of marine airbags after update.It's designed with lifting belts and shackles equipped on the update marine salvage airbags.
In order to meet the requirements of the ship salvage and rescue industry, we have redesigned the launching airbag. These can now be used as pontoons to support docks and other floating structures, and are also very useful for laying pipelines and other underwater construction projects to provide buoyancy. However, the main application of "Marine Salvage Airbag" is in shipwreck rescue, floating bridge and dock construction, rescue and removal of sunken ships and tidal flat ships.
After being deflated, the sea salvage airbag is very small in size and light in weight. Therefore, they can be easily transported and deployed. They can be used vertically to get sunken ships out of deep water. When the boat is suspended near the water surface, it can be suspended below the boat, and one end on each side raises the boat to a high enough water level to pump it out. In shallow water, two bags can be thrown together like a floating boat, one on each side of the boat. They can also be used as road rollers to push stranded ships back into the water, just like our "ship launches airbag".
Features of Marine Salvage Airbags
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.

Advantages comparing with PVC Air Lift Bags
PVC air lift bags are widely used for the diving or marine salvage industry. Marine salvage airbags are made by multilayer heavy-duty synthetic-tire-cord layers. It’s more sturdy and reliability than PVC air lifting bags, which is made only by one layer PVC coating fabric.
Super-high tensile strength — Heavy-duty synthetic-tire-cord layers is framework material of our marine salvage airbags. The breaking strength of each synthetic-tire-cord layer is more than 15,000 N / 5cm, which is two times of PVC coating fabric material.
Resistant to abrasion — The thickness of Evergreen Maritime marine salvage airbags is up to 12mm or more. The PVC air lift bag only is about 1.5mm. In bad environment, the PVC air lift bag is easily scratched or damaged by sharp objects. But our marine salvage airbags can resistant the scratch. Even the out rubber was damaged, the inner synthetic-tire-cord layer also can work well.
Multiple application — Normally, the parachute type PVC lifting bags used for the lifting work from underwater. The enclosed type lifting bags used for the buoyancy support of surface. But our marine salvage airbags are qualified for these two work, because of its high working pressure.
