What are the advantages to using this launching system over traditional ship launching techniques?
An marine airbag ship launching system does not need the traditional fabricated slipway so it saves time, investment, land, etc. Marine airbags need no extra maintenance and after use they can be cleaned and folded in the corner to wait for another mission. It is easy to find that airbags’ elasticity can give more protection to the launched ship. A remarkable character of airbags is that the working height can be changed to redirect the ship or object being launched by adjusting the inner air pressure. For this character it is peerless compared to traditional ship launching techniques.
●Airbags of different sizes are in stock
●Provide repair kit and on site instruction
●Long time service life can be reused many times
●Wear resistance and anti aging
●Good raw material and cord fabric
●Do no harm to the environment. Time & money saving
●Need no more than air compressors, winches and ropes
●Marine airbags are much cheaper and portable than other methods
Advantages of ship launching air bags
1.Less land form limited
Only need enough bearing power ground and no sharp objects
2.Minimum fixture needed
Need no more than air compressors,winches and steel ropes
Do no harm to the environment. No chemical needed.
4.Time & money saving
Marine airbags are more cheap and portable than other methods.

Loading of airbags
The requirements of launching ship and relevant equipments.
The engineering work under water line shall wholly be finished, especially those equipments, valves and others that are to be installed at the openings under ship waterline,the installations should be approved by inspection. All the burrs, welding beading and the like on the ship bottom or appendages should be ground away. All the welds on the shell plate must pass inspection and tightness test. The main dimensions of the ship should be measured up and the mark of loadline must pass inspection. All the paint work of the shell plate has been finished.
2. Ramp way
The ramp way on which the airbags will rolling should be cleaned and be clear of sharp fends such as iron nail. The ramp way should be leveled and the level error from left to right should less than 80mm. The ground caved in should be filled up and the ground bearing capacity should be relatively equalized. The ramp made of mud land, sanded land, sands or concrete, however, its bearing capacity should be twice as big as the working pressure of airbags. The slope of ramp is to be determined according to the size of the launching ship and is generally no bigger that 1/7. In the range of the whole length of the ramp way, the shape may be of multiple combination with slope line, are line and others. However, the ship bottom should not contact the ground even when the airbags are at their lowest working height. The ramp way should extend into water for certain length.
In general, a slow winch is to be selected, its veering speed is about 9-13/m/min. The moving speed of a ship must not be more than 6m/min with the control of hauling force of winch wire. If the ship weight is less than 200t, the moving speed can be increased properly. The wire must be inspected and replaced regularity.
The type and capacity of the air compressor is to be selected according to the total volume of all the airbags provided for the launching and time required for air filling and the air pressure. The gas tank of air compressor should be installed with
adjustable pressure limiting valve.
1.For ship upgrading, conversion or new/repair launching
2.Marine airbag for salvaging sunken ship or heavy immersed steel structure
3.For hoisting and transporting heavy goods up to 10,000 tonnes structure on land
4.For floating use purpose as improve the draft.
5. Container for storing and transporting gas and corrosive chemical liquid and pure water for voyage
6.Rubber airbags used for culvert making
