Salvage Pontoon – Vertical Enclosed Cylinder

Totally enclosed, cylindrical bags are ideal for shallow water salvage, reducing the draft of a vessel or raising an object closer to the surface. They are invaluable in cable and pipeline operations. These 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.
