BASIC INFO
Ship salvage airbags are now very popular in ship salvage. They can be used for saving when ship stranding happens. Nanjing Deers salvage airbags show high advantages in their convenience and versatility. Also, our airbags are highly praised by our clients for its good abrasive resistance. They also can be used as a floating structure to pipes and other heavy goods for they can offer buoyance from 10 tones to 50 tones.

Ship salvage airbags Functions
- Alternatives to rigid pontoon
Marine salvage airbags with high buoyancy from 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. At the same time, 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 the buoyancy of vessels when airbags are inflated with air. Typically, the maximum pressure of the computer compartment and deck should be composed before the airbag is inserted into the cabin. Sometimes, reinforcement should be performed to ensure that the deck and the cab can withstand the pressure of marine salvage airbags. - Jack stranded & sunken vessels up
For stranded vessels with more than 200 tons, marine salvage airbags can be applied to jack them up and send them back to the water without the need to dredging the watercourse or using crane airbag. For sunken vessels, insert marine salvage airbags between the bottom and seabed of vessels, then fill them with air to increase buoyancy of sunken vessels and jack vessels up. - Caisson launching
In the freshwater season, insufficient water level makes ship launching and caisson launching impossible. Therefore, buoyancy tanks and bags are needed. 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.
