Marine salvage exclusive airbags have similar structures to ship launching airbags but feature some optimal designs for salvage and flotation applications taking advantage of stiff and lightweight structure, lifting belts and buckles. Rubber belts are usually used to fasten airbags together and buckles make the binding much easier. Safe valves, mounted to the ends of airbags, are ideal for releasing inner pressure automatically when marine salvage airbags are applied in deep water. With the toughest pneumatic body, marine salvage exclusive airbags are generally used as temporary transportation device, or other applications such as shipwreck salvaging, floating bridges, dock construction, etc.
