Marine Airbags

Airbags is an innovative technology used in ship launching or upgrading in shipbuilding. It is simple and practical, it can save much money and time.
Ship launching airbags are made of heavy-duty synthetic-tire-cord layers with inner and out rubber layers in long cylindrical balloon shape.They are also known as inflatable marine airbags, roller bags, air lift bags, and salvage bags,widely use for used for tankers, tugboats, towboat, barges, cargo ship, ferries and other special vessels up to 100,000 DWT.
Deyuan marine can design ship launching airbags,salvage airbag,heavy lifting airbags
