Marine Ship Launch Airbags
Custom marine rubber airbags for vessel launching, dry docking, lifting and shipyard moving operations.
Marine Ship Launch Airbags for Launching, Lifting and Dry Docking
Marine ship launch airbags are inflatable rubber products used for vessel launching, dry docking, lifting, and moving heavy marine structures. Compared with fixed slipways or conventional launching methods, ship launching airbags offer a more flexible and cost-effective solution for small and medium shipyards, temporary launching sites, and maintenance operations. They help reduce infrastructure requirements while allowing vessels to be launched or repositioned with controlled support.
YT Marine manufactures ship launch airbags in customized diameters, effective lengths, overall lengths, and reinforced layer structures according to vessel size, hull form, launching conditions, and project requirements. Each airbag is built with durable outer rubber and high-strength synthetic tire-cord reinforcement for reliable bearing capacity and repeated use. Matching valves, pressure gauges, and inflation accessories can also be provided to support safe and efficient operation.
Ship launching airbags are one of the main shipyard and repair yard rubber products used for vessel launching, docking, lifting support and repair yard operations.

Ship Launch Airbag Structure and Selection Notes
A ship launch airbag consists of a cylindrical airbag body, cone-shaped end sections, reinforced rubber layers, synthetic tire-cord fabric layers, and metal end fittings. The reinforced body is formed and vulcanized to provide flexibility, bearing capacity, and durability during vessel launching, lifting, and moving operations.
Airbag mouths are installed at both ends for inflation and air release. The end fittings can be manufactured from carbon steel or stainless steel according to project requirements. Airbag diameter, effective length, total length, layer quantity, and working pressure should be selected according to vessel data, launching conditions, and site requirements.
Typical Selection Factors
| Selection Factor | Description |
|---|---|
| Vessel Weight | Used to estimate the required airbag quantity, bearing capacity, and working pressure. |
| Hull Shape | Affects the contact area between the hull and the airbags during launching or lifting. |
| Launching Slope | Helps determine the airbag layout, rolling direction, and operation method. |
| Ground Condition | Flatness, hardness, and surface condition should be checked before airbag operation. |
| Airbag Diameter | Selected according to vessel clearance, lifting height, hull support area, and site arrangement. |
| Effective Length | Selected according to hull width, contact area, and launching arrangement. |
| Layer Quantity | Designed according to required bearing capacity and working pressure. |
| Working Pressure | Confirmed according to airbag size, layer structure, vessel weight, and operation requirements. |
Final airbag selection should be confirmed according to vessel weight, hull shape, launching site conditions, airbag layout, and safety requirements.
