Ship launching with rubber airbags is an innovative technology that is widely used in the shipping industry. It is said to be introduced by the Chinese for use in emergency launching during the early 1980s. Over the years, ship launching airbags have been embraced by shipping industries in various parts of the world.  This technology helps to overcome fixed launching track challenges. This technology has offered flexibility and it saves both time and effort for small and medium-sized shipyards. The technology is reliable, safe and is a good investment for shipyards. This traditional technology was only effective in the launch and landing of small and medium-sized ships but today its application is more versatile in many ways.

Ship landing using marine rubber airbags relies on airbags that measure usually from 0.8m to 2.5m in diameter. These airbags usually have lengths from 5.0m to 25.0m. They are used to launch ships as well as other functions in floating, salvaging and loading. The airbags are popular for launching and landing chemical tankers and cargo boats. They are also effective for moving and lifting sunken ships or salvaging vessels that are stranded. Shipyards can save in investment expenses with these versatile and portable airbags.

Ship landing for repairs with rubber marine airbags makes it possible for vessels to land in locations that were previously restricted. Vessels no longer have to land on dry docks. The airbags have been tried and tested for several years and it is now possible to launch ships that weigh between 100 tons and more than 10,000 tonnes.

Ship launching or upgrading using marine rubber airbags is an innovative ship launching technology. It overcomes the disadvantage of "end-on launching", "side ship launching", "float-out". This ship launching technology overcomes the restrictions of the fixed launching track of side-launch.

This flexible ship launching technology is accepted by more shipyards worldwide because of its advantages of saving time, saving investment, flexibility, safety. We are constantly innovating in terms of design, material usage, & manufacturing technologies throughout the years to ensure flexibility, safety, and reliability.

Up to now, more cargo vessels, barges, chemical tankers, tugboats, AHTS vessels, floating docks, and even construction caissons have all been launched using our ship launching rubber airbags. The biggest vessel launched by ship launching airbags up to 100,000DWT.

Ship launching Marine Rubber Airbags Specification and Model

You can choose the required diameter and effective length to meet your projects. Refer to how to select marine rubber airbags to know more. The below specification only is our standard specification arrange. Other specifications Ship Launching Airbags also can be supplied upon clients' request. For other information, you also can refer to Airbag Launching.
 

Ship landing airbags are categorized by the following three types according to the bearing capacity, per meter in length. We define the number of layers, which means the number of Synthetic-tyre-cord layers, in order to confirm the Safety Working Pressure. Another type is available upon clients' request.

• QP - Ordinary airbag - with 3, 4 or 5 layers of cord fabric.
• QG - high-bearing capacity airbag -  with 6, 7, or 8 layers of cord fabric.
• QS - Superhigh-bearing capacity airbag - with 9, 10, or more layers of cord fabrics as a custom request.
