Ship Launching Airbags, also known as roller bags or ship launching balloon, is a innovative technology having utmost developmental prospect in shipbuilding. It can be used for the ship launching or ship landing of tanker, tugboat or barges, carrying vessel, carrier, ferry and other special vessels (AHTS, DSV) and so on. The biggest vessel launched by ship launching airbags up to 85,000 DWT.
This ship launching technology overcomes the restrictions of fixed launching track of side-launch and accepted by more more shipyard world wide because of its advantages of saving time, saving investment, flexible, safety.
Construction Features of ship launching airbags:
Ship Launching / Shipping Marine Airbags, basic body consists of which consist of our rubber layers, synthetic-cord-reinforced rubber layers, are kind of a cylindrical airbags with hemispherical heads at the both ends. All of these are vulcanized together, and then compress air inside to enable in to roll.
1. Outer Rubber
The outer rubber layer that covers the outside of ship launching airbag protects the cord layers from abrasion and other external forces. This compound has sufficient tensile and tear strength to withstand any weather condition and hard usage.
2. Synthetic-tyre-cord layer for reinforcement
The reinforcement cord layers of ship launching marine airbags, which are made of Synthetic-tire-cord commonly used in tires, are arranged at ideal angles to hold the internal pressure and to distribute the stress evenly providing strong efficient reinforcement.
3. End Fittings
End fittings of Ship Launching Marine Airbag include air tightness swivel and airbags safety air inlet.
Features and Advantages of ship launching airbags:
♦Unique whole enlacing technology

Acceptance Test for Commercial Ship Launching Airbags
DOLPHIN MARINE test the ship launching airbags purchased based on the test items indicated below:
1. The appearance of each Evergreen Maritime ship launching airbag is smooth, glossy and without blemish such as crack, blister, delamination, pits or impurities.
2. The length and diameter of each Evergreen Maritime ship launching airbags are measured with the rated working pressure and is within ±3%.
3. The gas-tightness is tested without carrying any load as per ISO 14409. The pressure loss is less than 5% of rated working pressure within 1 hour.
All DOLPHIN MARINE ship launching airbags are manufactured and tested comply with ISO 14409 “Ships and marine technology – ship launching air bags“, certificated by CCS, LR, DNV.
