Advantages of salvaging airbags

The application of salvage airbags in maritime salvage and buoyancy assistance is very extensive, including rescuing stranded or sunken ships, and so on. Due to the suddenness and strong timeliness of maritime salvage and rescue projects, if salvage companies use conventional lifting methods, they are often constrained by large lifting equipment or require high costs; By using airbag assisted technology, salvage companies can quickly and flexibly complete salvage and rescue work.
The overall salvage methods for large sunken ships mainly include float salvage, floating crane salvage, etc. At present, almost all pontoons used in the float method are rigid pontoons made of hard materials. The rigid buoy has a large lifting capacity and is easily affected by the underwater environment when diving and being tied to sunken ships. In addition, the buoy occupies a large space and has high storage and transportation costs. Large floating cranes are the main tools for maritime salvage, but they are often limited by the lifting capacity of cranes, coupled with high transportation costs, which can lead to an increase in salvage costs.
The salvage airbag made of flexible materials is flexible and versatile, and can be folded or rolled into a cylindrical shape for storage and transportation or diving, greatly improving the salvage ability of salvage companies. When in use, sink the airbag into the seabed, fix it with the salvaged object, and then inflate it into the airbag to float it up, dragging the sunken ship out of the water. The salvage airbag can be inserted into the flooded cabin or fixed to the sunken deck of the ship, with a small force on the unit area of the hull, which is powerful for ship safety. The impact of hydrological conditions is relatively small when fishing for airbags and diving, resulting in high efficiency of underwater operations.
Salvage airbags not only provide buoyancy for ship salvage, but also have great potential in rescuing stranded ships. By means of excavation and other means, airbags can be inserted into the bottom of stranded ships. Inflation of airbags can lift the ship, and under the drag or thrust of tugboats, the ship can smoothly enter the water.
