DOOWIN marine salvage bags are totally enclosed cylindrical shape design. It is known as enclosed air lift bags, inflatable buoyancy units, or salvage pontoon.
Marine salvage bags are mainly used for buoyancy support, marine salvage and re-floatation operation. Furthermore, we also can use marine salvage bags as buoyancy support pontoons for bridges, floating platforms, dock gates, sunken objects or military equipment. Marine salvage airbags offer an effectual floatation method of reducing the draught of the vessel and lift bag salvage underwater structures. Likewise, these marine airbags also are ideal buoyancy modules for cable or pipeline laying and boat lift air bags.
