WHAT IS marine salvage airbags
marine salvage airbags are specialized air bags that are used for launching marine vessels. These air bags are made of synthetic-tire-cord reinforcement layers and rubber layers,and are also known as marine airbags. They were invented in 1980.The first known use of marine airbags occurred on January 20, 1981 with the launch of a tank barge from the Xiao Qinghe shipyard. From then on, more and more shipyards, especially in China and Southeast Asia, began to use air bags to launch small and medium-sized vessels.
In recent years, higher strength materials have been used in air bag production, allowing them to have much more bearing capacity. Hence, they have begun to be used at the launching of larger vessels. In October 2011, the successful launch of one vessel with a deadweight tonnage (DWT) of 75,000 tonnes set a world record (NANHAI Project Case) for ship launches utilizing air bags.The following year, on June 6, 2012, the ship "He Ming", with a DWT of 73541 tonnes, total length of 224.8m, breadth of 34m, and depth of 18.5m, also launched successfully using air bags.
