1. INTRODUCTION
Marine Rubber Airbag is china independent intellectual property rights of innovative products, the products are mainly applied to ship launching and landing, weight lifting and moving, installation of underwater buoyancy aid to salvage sunken vessels etc. Airbags launching technology was developed based on traditional slipway launching mode, it overcomes the restrictions of traditional slipway launching mode. Our marine rubber airbags are less limited by space, no large mechanical equipment, can shorten the working period and save the unnecessary cost. Through years of development practice, our products are become more safety, effective and green environmental protection and they can launching a ship up to 100,000 DWT. Nowadays, Marine rubber airbags are widely used in the world.
