Product Details

Totally-enclosed cylindrical type Mono buoyancy bags are ideal for shallow water salvage, reducing the draft of a vessel or raising an object closer to the surface. This type buoyancy units are invaluable in cable and pipeline operations. These buoyancy bags are rigged with a single bottom and top pick point with internal strap to allow for the load to be lifted from the top of the bag. Vertical type pipelaying buoyancy bags are mainly used for the pipeline laying installation and pull to provide buoyancy support as buoyancy bags.
