Ship Launching Airbag

Ship Launching Airbag

Ship launching airbag can be used to launch and upgrade a ship up to 100,000DWT. The 'flexible launching techonology' makes this new ship launching method widely used all over the world. It is widely applied for ship launching, heavy lifting and moving, and buoyancy with superior advantages, such as significantly reducing cost (well over 30%) as well as being safe, easily adaptable to various harsh working environments, and environmentally friendly etc

Airbag specification and performance
The bearing capacity at work pressure is calculated as follows:
Q=p·S……………………（1）
Where: Q—Bearing capacity of airbag;
p--Work pressure of airbag;
S--Frontal projected area of contact surface.
The width, B, of the airbag’s contact with a heavy object or ground when the airbag is pressed to certain height, H, (See Fig. 7) can be calculated according to the following equation:
B=∏/2（D-H）………………（2）
