The 35T salvage buoyancy bag is a device used for underwater salvage operations. It can provide 35 tons of buoyancy and is mainly used for salvaging sunken ships, large underwater objects, etc.
Some 35T salvage buoyancy bags feature an open-bottom design, which provides safer lifting and more stable operation. Additionally, some bags feature a unique "untangle" for rigging in zero visibility, and some have a top-mounted air release valve for convenient buoyancy control via the bottom rope.
