Marine salvage airbags have a wide range of applications in marine salvage flotation assistance, including rescuing stranded ships or flotation assistance to sunken ships and so on. Because the maritime salvage and rescue project is sudden and time-sensitive, if the salvage company adopts conventional lifting methods, it is often restricted by large-scale lifting equipment or requires high costs; using airbag assist technology, the salvage company can be fast Flexible to complete salvage and rescue work.
The overall salvage methods of large sunken ships mainly include pontoon salvage and floating crane salvage. Almost all buoys used in the current buoy method are rigid buoys made of hard materials. Rigid pontoons have high buoyancy capacity, and are easily affected by the underwater environment when they are submerged and tied to a sunken ship. In addition, the pontoon takes up a lot of space and has high storage and transportation costs. Large floating cranes are the main tool for maritime salvage, but they are often limited by the lifting capacity of the cranes, coupled with high transportation costs, which will increase the cost of salvage.
The salvage airbag made of soft material is flexible and versatile, and can be folded or rolled into a cylindrical shape for storage and transportation or diving, which greatly improves the salvage capacity of the salvage company. When in use, the airbag is sunk into the bottom of the sea, fixed with the salvaged object, and then inflated into the airbag to float the airbag and drag the sunken ship out of the water. The salvage airbag can be stuffed into the water-ingressed cabin or fixed to the shipwreck deck. It has a small force per unit area of the hull and is powerful for hull safety. The salvage airbag is relatively less affected by hydrological conditions when it dives, and the underwater operation efficiency is high.
Salvage airbags can not only provide buoyancy for salvaging ships, but also have great potential in rescuing stranded ships. Through excavation and other means, the airbag can be stuffed to the bottom of a stranded ship, and the airbag can be inflated to lift the ship, and the ship can enter the water smoothly under the drag or thrust of the tugboat.
