Marine Rubber Airbag Application

1 Ship Launching & Upgrading

With more than 20 years development in China, marine rubber airbag is proved to be the most reliable and stable technique for ship launching & upgrading. It is applicable from tons of flat board to ten thousand tons of huge ship. Meanwhile, marine rubber airbag is also widely acknowledged by foreign dockyards, shipyards, port/harbour construction companies. Ship launching & upgrading technique with marine rubber airbag is also highly promoted in the markets, such as America, Europe, Southeast Asia.

2 Weight lifting & moving

Marine rubber airbags could be applied to caisson lifting, launching, moving and transporting in port constructing projects.

3 Buoyancy Aid & Salvage

Because marine rubber airbag has buoyancy force and load-bearing capacity, it is also widely used in sunken vessel salvage and Buoyancy Aid.

High pressure safety explosion-proof launching airbag

(1). Using high quality raw material

(2). The unique whole winding process

(3). The size and structure of air bag

Other models c an also be produced according to customer requirements.

How to ensure success, rather than a catastrophic and embarrassing failure

1) Identifying the type, size & weight of the vessel before you launch.

2) Type, length and number of airbags have to be chosen carefully.

3) Ground structure/ slipway has to be free of sharp objects and preferably, a small degree slope.

4) Slipway Winch to provide pulling force needed.

5) Determine the accessories needed for ship launching using airbags.

6) Determine whether a slow launch or quick launch.

7) Rubber inflatables are versatile

8) Cost advantage due to flexibility.

How It Works Using Marine Airbags for Ship Launching and Pulling

Place airbags under the vessel between the supporting blocks and inflate them to lift the vessel. And then remove the blocks under the vessel after lifted.

For the light weight vessel, only several pieces airbags can fully lift the vessel at one time and then remove the blocks and place more airbags for launching.

For the big weight vessel, it will be lifted step by step.

First put the airbags under the vessel. Second: Pump part airbags, if vessel is lifted from blocks then remove blocks.

The sequence of block removal is middle first then sides.

Third: Adjust inflated airbags’ position to be accurate since during lifting some airbags’ positions are hampered by blocks.

Fourth: Pump more airbags to continue release blocks and remove them.

Fifth: Repeat pumping and remove until all blocks are removed. During this process some blocks may be difficult to be released, people may pump airbags’ pressure to be high pressure. If high pressure still doesn’t work, people may deflate some groups of airbags and underlay them. Sixth: When all blocks are removed adjust airbags’ position. Seventh: Adjust pressures of airbags.

2. Adjust airbags’ pressures. Check all airbags’ working height, especially airbags at bow, if working heights are less than 0.3 m then people should adjust the airbag’s pressure to increase its working height.

3. Block launching area and prepare good communication for the launch command.

4. When water level reach desired level, cut off pulling ropes and release the vessel. If the launching water area is limited, people may use winch to release the vessel slowly into the water.

5. Reclaim airbags after launch.
