The 81-meter engineering barge "Sanhang 601" was successfully launched using airbags
At 4:08 pm on March 7, 2012, on the slipway between the 1#---2# slipway of Yangzhou Kejin Ship Industry Co., Ltd., which is located in the shipbuilding industry belt along the river in Yangzhou City, after the upper row was refitted Shanghai's "Sanhang 601" engineering barge was successfully launched using the airbag water launching technology.
The total length of the project barge is 81 meters, the molded width is 36 meters, and the weight of the empty ship in the launched state is more than 3,100 tons. The top row and launch project of the ship refit project is contracted by Shandong Changlin Ship Airbag and Ball Rear Technology Research Center. In the process of formulating and implementing the plan, the difficulty of getting in and out of the water caused by the ultra-wide ship type, the small distance between the two slideways and the slideway being higher than the ground (higher than 700mm) was considered. The scheme adopts 27 engineering-specific airbags produced by Jinan Changlin Airbag Container Factory Co., Ltd., adopts a series of schemes such as local riprap reinforcement and bedding of underwater ramps, temporary winch ground cow foundation on the top of the slipway, and strict control of airbag layout accuracy. Measures to ensure the safety and smoothness of the upper and lower water projects. The personnel of the launching team of the center overcame the difficulties of poor site conditions and tight operating time, and completed the upper row project from January 16th to 18th, 2012. After a month of renovation and construction, the launch was successfully completed on March 7th.
The successful launch and launch of the ship using airbags laid the foundation for the research and project implementation of the launch of large engineering ships in the future.
