1.5m x 12m Rubber Marine Air Bag for Launching Ships and Boats in Shipyards
Marine air bags are widely used in medium and small shipyards alongside rivers and seasides in Asian and American countries. Marine air bags 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 air bags 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.
Key Features of Launching Vessel Marine Air Bags:
1. Flexible in various launching projects: Launching Airbags 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 airbags is releatively easy, just laying out and inflating the airbags 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
The layout of Marine Airbags for Vessel Launching
According to the breadth of ships, there are usually 3 patterns of airbag layout:
