DOOWIN CE Certified Pneumatic Air Bags for Marine Salvage Operations
Marine salvage rubber airbags provide reliable buoyancy solutions for ship launching, salvage operations, and offshore facility recovery. These heavy-duty pneumatic airbags are engineered with lifting belts and shackles for secure handling in demanding marine environments.
Marine salvage airbags represent the toughest air lifting technology available. They serve as salvage pontoons for supporting docks, floating structures, and excel in shipwreck salvage, floating bridge rescue, and dock construction applications. The robust pneumatic rubber body ensures superior performance in severe environmental conditions.
Compared to traditional steel floats, pneumatic buoyancy airbags offer significant advantages: greater buoyancy assistance with lower economic investment, making them ideal for underwater installation of steel components and ship salvage operations.
Key Features
High-tensile outer rubber layer with multiple heavy-duty synthetic-tire-cord layers
Vulcanized inner rubber layer for maximum durability and longevity
Integrated lifting belts and shackles for secure handling and positioning
Safety valves for automatic pressure release in deep water applications
Cylindrical balloon design with conical heads and airtight swivel connections
Polyester webbing lifting straps with 6:1 safety factor buoyancy rating
Superior toughness compared to standard PVC underwater air lift bags
Primary Applications
Marine salvage airbags excel in demanding environments where reliable, controllable buoyancy is essential:
Pipeline float-out operations
Beach pulls and river crossings
Vessel and platform draught reduction in shallow waters
Temporary bridge and dock pontoons
Heavy-duty salvage operations in severe conditions
Buoyancy Capacity Specifications
Standard marine salvage airbags offer various buoyancy capacities with multiple diameter and length combinations:

All Doowin Marine salvage airbags are manufactured and inspected to fully comply with ISO 14409 "Ships and marine technology - ship launching air bags" and IMCA D016, certified by CCS, LR, BV.
Advantages of Rubber Marine Salvage Airbags
Rubber marine salvage airbags are constructed with multilayer heavy-duty synthetic-tire-cord layers, making them 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
Structural Design
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.
Quality Assurance
From raw materials to highly skilled production processes, our engineering team constantly improves product quality. Our rubber rollers are manufactured and tested to comply with ISO 14409, certified by CCS, LR, DNV.
