High Pressure Launching Ships and Boats Marine Rubber Air Bags
Marine rubber air bag typically has a body of cylindrical shape and two conical heads, one at each end. At each head end, there is a metal bushing as a mouth for air inflation and the plug with a ring.
Please refer to the drawing of a typical marine airbag and its accessories below to know the structure and accessories.
Key Features of Launching Vessel Marine Air Bags:
1. Flexible in various launching projects: Launching ship air bags can be made to be specified sizes and layers as per the requirement of different launching projects.
2. Easy Operation: The operation of launching vessels with rubber air bags is releatively easy, just laying out and inflating the air bags to lift the vessels and roll them to the water.
It has not strict requirement on slipway conditions. Ship launching can be executed even in tough conditions.
3. Durable and recycled: Marine Airbags can be used many times repeated.
4. High economy: As marine airbags can be used repeatedly and its cost is not high, launching or docking ships with marine airbags can save much cost for shipyards or ship owners.

How to Launch Vessels with Marine Air Bags
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
