Product Description

Product Description

 

Doowin Marine ship launching airbags are all manufactured and tested fully compliant with ISO 14409:2011 

Marine rubber airbags are widely used in loading, floating, lifting and moving sunken ships, and salvaging stranded boats.

Ship launching or upgrading using marine 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.

Installation Instructions

Rubber airbags are made of out rubber layers, multilayer heavy-duty synthetic -tire-cord layers,and inner rubber layer vulcanized firmly. 
Many synthetic-tire-cord layers are twined at ideal angles by unique and patented"Holistic Wrapping Technology". To hold the internal pressure and distribute the stress evenly.

Ship Launching 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.
