70,000 dwt Ship 'New Dongguan 1' Used Changlin Air bags to Launch

On December 3rd of 2010, the 70,000-dwt bulk carrier “Xin Dong Guan 1” was built up by Zhejiang Zhenghe Shipbuilding Co., Ltd., and successfully realized the airbag launching. It was 222 m in overall length, 32.26 m in mold width, 18 m in mold depth and 11.3 m in full draft with the displacement of 70,541 t and a launching weight reaching 13,000 t. The ship launching not only created a new record of airbag launching tonnage but also adopted a series of new technology of airbag launching. For example, the airbag layout adopted different spacing type and the horizontal patchwork plan was a major technological innovation. During the ship launching process, Zhejiang Industry University was delegated to carry out structural stress measurement. Therefore it would be a major contribution to study airbag launching of large ships.
