pontoons for boats are packaged into one flexible bag made of PVC coating fabric.Then package in one plywood box.
Ship boat air lifting bags are mainly used for buoyancy support and marine salvage and refloatation operation in shallow water. We also can use enclosed lifting bags as support/salvage pontoons for bridges, floating platforms, dock gates, sunken objects or military equipment. Ship boat underwater air lifting bags offer an effectual method of reducing the draught of vessel and floating underwater structures. Then also provide an ideal system of buoyancy for cable or pipeline and static buoyancy support.
