2m x 15m Indonesian Shipyards Lifting and Launching Ship Rubber Airbags
Launching ship marine airbags are widely used for ship launching and docking in shipyards, specially medium and small shipyards alongside rivers and seasides in Asian and American countries. Marine airbags are often called ship launching airbags that indicates the most popular application of these heavy duty airbags is for ship launching. It is estimated that more than 80 percent new built ships who’s DWT below 60,000 are launched by marine airbags.
Launching with marine airbags is very flexible. Any flat ground with a slightly declining angle can be taken as a slip way. Airbags can sucessfully launch a ship even on a bank 1 or 2 meters over water level.
The Size and Specifications of Ship Launching Airbags
Ship launching airbags can be made into various sizes and layers accoding to the ship size and weight and the launching or docking conditions.
Size | Diameter | 1.0m, 1.2m, 1.5m, 1.8m, 2.0m, 2.5m, 2.8m, 3.0m |
Effective Length | 10m, 12m, 15m, 18m, 20m, 22m, 24m, etc | |
Layers | 4 layers, 5 layers, 6 layers, 8 layers, 10 layers, 12 layers |
Below is a chart for the bearing capacity of several sizes

How to Launch Vessels with Marine Airbags
Below is the general process of launching ship with marine rubber airbags.
1. Get enough suitable airbags ready
2. Level and Clean the launching slipway to make sure no nails or sharp stones
3. Tie the ship to the winch with steel wire
4. Lay airbags under ship bottom at suitable locations
5. Inflate the airbags to lift the ship away from the blocks and remove the blocks
6. Lower the lifting height properly by releaseing some air
7. Slowly release the wire and roll the ship slowly backward to the water
The layout of Marine Airbags for Ship Launching
According to the breadth of ships, there are usually 3 patterns of
airbag layout:
