Ship launching airbag is a complicated process in ship industry. On inland waterways and coastal ships, the launching of ships generally adopts track sliding and airbag rolling. Because of the high investment cost, a shipyard or a dock is needed. Factors such as the small scope of application are generally selected only by large shipyards. Marine airbags are widely used by small and medium-sized shipyards due to their small overall investment.

The Marine airbag launch process uses high-pressure inflatable rubber airbags to bear the weight of the ship itself. Through the rolling deformation of the airbag and the ship's own weight and the slope of the land, the new ship is launched smoothly. The offshore airbag process abandons reliance on berths or docks for traditional ships, and combined airbags have been used to translate the launching of ships with deadweight over 20,000 tonnes. The technology has been developed and developed rapidly in China. It is first welcomed by small and medium-sized shipyards with shortage of funds and imperfect hardware facilities. Later, large shipyards also assisted in launching ships using this method.

The application of airbag has led to the rapid development of China's shipbuilding industry. Especially in recent years, 90% of China's large private shipbuilding bases and new shipyards have used air bags to launch and unload ships, and have achieved considerable economic benefits. The total investment in airbags is less than 5% of the investment in raw water terminals. This is a promising industrial project.以上翻译结果来自有道神经网络翻译（YNMT）· 通用场景
