5. Marine Rubber Airbag Application
4. 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.
4.2. Weight Lifting & Moving
Marine rubber fend could be applied to caisson lifting, launching,
moving and transporting in port constructing projects
4.3. 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.
