Ship launching airbags, also known as roller bags, launching air balloons, inflatable marine airbags, air lift bags, and salvage bags, are specialized marine rubber air bags used for launching marine vessels, ship landing or haul-outs. These airbags are widely used in loading, floating, lifting and moving sunken ships, and salvaging stranded boats.
Ship launching using marine airbags is an innovative technology that overcomes the disadvantages of traditional methods like "end-on launching", "side ship launching", and "float-out". This flexible technology eliminates the restrictions of fixed launching tracks and is increasingly adopted by shipyards worldwide due to its advantages in time savings, cost efficiency, flexibility, and safety.
Our engineering team continuously innovates in design, material usage, and manufacturing technologies to ensure flexibility, safety, and reliability. Our ship-launching rubber airbags have been used to launch cargo vessels, barges, chemical tankers, tugboats, AHTS vessels, floating docks, and construction caissons, with the largest vessel launched reaching 100,000DWT.
All Doowin Marine ship launching airbags are manufactured and tested to fully comply with ISO 14409:2011 (Ships and marine technology -- Ship launching airbags) and ISO 17682:2013 (Methodology for ship launching utilizing air bags).

Our rubber airbags are constructed with an outer rubber layer, multi-layer synthetic-tire-cord layers, and inner rubber layer vulcanized firmly, with additional layers applied at the end shoulders for enhanced durability.
The synthetic-tire-cord layer serves as the reinforcement layer, made of rubber-coated synthetic-tire-cord fabrics. Multiple layers are twined at ideal angles using our patented Holistic Wrapping Technology to evenly distribute stress and hold internal pressure. We use 1400 dtex/2 or 1400 dtex/3 type synthetic-tire-cord fabric with over 95 cords per 100mm width and breaking strength exceeding 310N per cord.
- ISO 14409 - 205 N/ per cord
- 1400 dtex/2 - 215 N/ per cord
- 1400 dtex/3 - 313 N/ per cord
Both outer and inner rubber layers undergo rigorous testing to meet international standards. The outer rubber layer protects cord layers from abrasion and external forces, featuring compounds with excellent tensile and tear strength to withstand harsh weather conditions and heavy usage.
