Ship launching airbags are known as roller bags, launching air balloons, inflatable marine airbags, air lift bags, and salvage bags. Ship launching airbags are specialized marine rubber air bags that are used for launching marine vessels. ship landing or haul-outs. Marine rubber airbags are also widely used in loading, floating, lifting and moving sunken ships, and salvaging stranded boats. Rubber airbags are made of heavy-duty synthetic-tire-cord layers with inner and out rubber layers in a long cylindrical balloon shape.
Ship launching or upgrading using marine airbags is an innovative ship launching technology. It overcomes the disadvantage of "end-on launching", "side ship launching", "float-out". This ship launching technology overcomes the restrictions of the fixed launching track of side-launch.
This flexible ship launching technology is accepted by more shipyards worldwide because of its advantages of saving time, saving investment, flexibility, safety. We are constantly innovating in terms of design, material usage, & manufacturing technologies throughout the years to ensure flexibility, safety, and reliability.
Up to now, more cargo vessels, barges, chemical tankers, tugboats, AHTS vessels, floating docks, and even construction caissons have all been launched using our ship launching rubber airbags. The biggest vessel launched by ship launching airbags up to 100,000DWT.
All Doowin Marine ship launching airbags are manufactured and tested fully compliant with ISO 14409:2011 Ships and marine technology - Ship launching air bags.
