The PSM submarine lifting bag is the ideal unit to use for the flotation and stabilization of loads within an underwater environment, and the bags are available in a variety of capacities ranging from 100kg to 5tons. All PSM submarine lifting bags are manufactured from a PVC-coated polyester fabric that is assembled by high-frequency welding.
There are a number of specific systems designed and adapted by the maker's engineering service to suit specific operating requirements, and operators can additionally combine a number of PSM lifting bags to increase the total lifting capacity. This is the ideal line of submarine lifting bags to use for the lifting of heavy submarine loads to the surface, the lifting of loads in a nuclear environment, and lifting offshore loads or bringing a wreck to the surface.
