Marine salvage and floatation is another application of ship launching marine airbags after update. Doowin Marine marine salvage airbags are designed with lifting belts and shackles equipped on the updated ship launching airbags.

Marine Salvage Airbags are the toughest air lifting bags. They can be used as salvage pontoons for supporting docks and other floating structures. Also suitable for shipwreck salvage, floating bridge rescue, and dock construction. With the strongest pneumatic rubber body, these salvage rubber airbags excel in heavy-duty salvage work under severe environments.

Marine salvage airbags offer different buoyancy capacities with numerous combinations of diameters and lengths. Below is the buoyancy list of standard marine salvage airbags:

All Doowin Marine marine salvage airbags are manufactured and inspected fully compliant with ISO 14409 "Ships and marine technology - ship launching air bags" and IMCA D016, certificated by CCS, LR, BV

Rubber marine salvage airbags are made by multilayer heavy-duty synthetic-tire-cord layers. They are more sturdy and reliable than PVC air lifting bags commonly used in the diving or marine salvage industry.

• High Buoyancy Capacity
  Salvage rubber airbags create high buoyancy capacity with safer air pressure, ranging from 4t to 300t.
• Deep Water Operation
  These marine salvage rubber airbags can be used for deepwater salvage lifting and can be equipped with safety valves.
• Abrasion Resistant
  Salvage rubber air bags feature 6-12 plies reinforcement layers to withstand most abrasion and puncture.

Marine salvage airbags are equipped with lifting belts and shackles. For larger sizes, we install safety valves that automatically release inner air-pressure when reaching the rated value.

You can select the required diameter and effective length for your projects. The specifications shown are standard arrangements, but we can supply other specifications upon request, with buoyancy capacity up to 300 tons.
