Launches 230' barge from 300' barge deck with airbags
In September 2014, Eversafe Marine worked together with Indonesian PMG corporation, launched one 230 feet barge from the deck of one 300 feet barge with marine airbags.
That launched 230 feet barge measured 64 feet by width and 14 feet by depth; the mother barge, measured 300 feet by length, 90 feet by width and 20 feet by depth. Those two barges were built in Nantong Yahua Shipbuilding Corporation, completed at the same time. By airbag launching, the 300' barge entered into water first, the 230' barge was loaded into it with 1200 T floating crane. Then two barges were towed to Indonesia Tarakan.
To roll a vessel into water from another floating vessel is a big challenge, especially when they have close dimensions.
By calculation, Eversafe team optimized the ship launching plan again and again to reduce the vessels' impact energy to be minimum. With well arranged marine airbags, the impact energy will be absorbed safely.
At noon of 10th September, the final launch started. When the holding wire ropes were cut off, the 230' barge moved with rolling airbags slowly, passed over the mother barge' bow and entered into the sea gently, even no big splash.
The success of launching a vessel from another vessel's deck means a lot: It can be referred for other deck launching projects, such as the jackets launching. It comes to be possible to launch vessels at remoted areas without assistant facilities, only airbags.
Airbag launching technique was found to be versatile and flexible in marine engineering fields. Airbags can lift up mega heavy like jacks and move it forward，act as pneumatic rollers. Airbags can roll over pits and knuckles, so they have less demands of the ground or ramp. Different from rigid trolleys, airbags can be compressed at different ratio, thus they can absorb the impact energy emerges in some structure launching projects.
