General introduction of Ship launching with marine airbags. The traditional ship launching methods include end on launching , side launching and dry dock floating. Most airbag ship launching are end on launching.
If the“Dawson”inflatable rubber ship airbag was damaged, it can be repaired as long as the rubber doesn’t age serious (with no crack and sickness on the surface), repair can be made by sickness coating cord fabric......
First, the airbag must be checked if the pressure gage is normal before being used.
Airbag launching technology is especially good for temporary launch project because of its low demand of launch conditions. Huge steel cofferdams are fabricated for bridge piers construction, some of them weigh a few thousands tonnes that is difficult for floating crane to lift and install.
Lots of big or small ship launching accidents are caused by less attention to ship holding system that include ground anchor , winch, pulley, wire ropes and shackles. In the below case people employed a bulldozer to hold the ship, without suspense the bulldozer was launched into water with the ship.
