Marine Airbags for Ship Launching/Ship Pulling/Salvage

Ship launching using marine airbags is a very popular vessel launching method. It overcomes the shortcomings of the fixed launching track, which limits the productive capability of the small and medium sized shipyards. Now it has become a Flexible Launching Technology, having the merits of time and labor saving, flexibility, reliability and safety in operation and comprehensive economic benefits etc.

• Saving the investment of shipyard construction
• Simple operation, saving of labor and work hours
• Environment friendly

After years of practice and accumulation of experience, we have developed the technology from launching only 1,000 DWT ships to current 100,000 DWT ships and we will achieve more. And now this technology has become a flexible, promising, secure and mature technology. Besides that, these airbags are widely used in slipping of ships and boats of all sizes.
