In Southeast Asia, launching ships with airbags is a very common launching technique. The diameter of the ship launching airbag we usually use is between 0.6m~1.5m, which is enough for the launching of new boats in most shipyards. Recently, Sunhelm undertook the launching project of a ship weighing 5000t. This behemoth is expected to be launched in 6 months using our marine airbags. For the first time, Sunhelm successfully manufactured a super large ship launching airbag with a 3m diameter×12.5m length. The airbag has 15 layers. For Sunhelm, this is a huge challenge in production technology. Few airbag manufacturers can produce such multi-layer marine airbags.We are very happy to see a good result. Now, these airbags have completed the air leakage test and the water injection pressure test, and they are inflated and pressure-maintained at the factory for delivery.

For each ship launching airbag order of Sunhelm, the customer will be equipped with a set of instruction manual, which records in detail how to inflate the marine airbag, how to replace the accessories, how to maintain the marine airbag and so on. In addition, we will give VIP customers a set of inflatable accessories, which include inflation tubes, valves, tee, pressure gauges and other vulnerable accessories. If the pressure gauge is accidentally damaged during transportation or use, you can replace it by referring to the user manual. If you still have questions that you don’t understand, you can directly contact your salesperson and ask for video technical guidance. Sunhelm will do its best to solve your problem.
