The ship up to slipway and launch by air-bags is a new technology of having good prospect in the future; it overcomes disadvantage of the capacity of repairing and shipbuilding by medium and small ship factories was enslaved to fixed type slipway, and developed to flexible and soft launch technology nowadays; it has many obvious advantages, such as operator saving, time saving, labor saving, investment saving, motive and flexible, safe and reliable, and has obvious integrated economic benefit.

　Because of adopting new style and high strength air-bags, it supplies technical safeguard for breaking through the launch of 10.000 tons ships.

　This kind of high pressure air-bags are developed responded to the request of large ship factories. In the process of vertical launch, for an instant floating of tails, the head bracket of large ships was damaged because of centralized under stress; it is a valuable grouping measure to use the buffer action of air-bags distortion for protecting the ships were not damaged.

　In Oct. 8, 2003, Nanshagang District, dock construction project (CHEC Guangzhou Port Construction Co., Ltd.) use superhigh pressure air-bags, to successful move the largest and heaviest dock caissons (17.84m long, 14m wide and 18.9m high, each looks like a 6 floors high building that contain 267.6 square meters and the weight is 2212 tons) in South China to the destination. Use this technology not only shorten the time limit of the project, but also save 4/5 budget fund of project. There are no examples of using air-bags conveying method to convey these busters before in the country. Many medias such as Guangzhou Daily, Nanfang Daily, Nanfang City Newspaper, Yangcheng Evening Newspaper, Yuegang Information Daily, Guangzhou TV station, and Guangdong TV report this event.

　At the beginning of May 2005, in dock construction of Guangxi Fangcheng port, the Fangcheng port project department of CHEC Guangzhou Port Construction Co., Ltd. adopted air-bags movement craftworks, successfully move 11 biggest cylinder caisson that more than 2900 tons, and set a record of adopting air-bags movement super sized cylinder project in world dock and harbor construction history.

　The biggest cable stayed bridge in the world--Sutong Bridge has already began to construction; The keypoint of this project is lifting and movement of large steel overhead bin (about 3200 tons); The construction scheme finally would adopt large diameter and superhigh pressure air-bags construction to smoothly finish project difficulties.
