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.

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.
