Marine airbag also known as rubber airbag, ship launching airbag, ship salvage airbag, inflatable airbag, ship lifting bag, air balloon, made by rubber & multiply layer of rubber-dipped tyre fabric. Airbags are widely used in launching and landing ship/ boat/vessel, lifting and moving heavy goods, salvaging stranded boats. Air bags have the benefit of not only saving labor and time, but investment costs. Additionally they are flexible, portable, and dependable. Marine airbags are very popular with shipyard, ship owner, and marine supplies company now.
Â
1. Construction Features of Airbags
Â
Marine Airbags have the best designed structure which consists of five different functional membranes in rubber layers.
Â
1) Outer Rubber Layer
The outer rubber layer that covers the outside of marine airbag to protect under layers from abrasion and other external forces. This compound has sufficient tensile and tearing strength to withstand any condition and hard usage.
2) Inner Rubber LayerÂ
The inner rubber layer seals pressurized air inside marine airbags.
3) Synthetic-Tire-Cord Layer as Reinforcement
The reinforcement cord layers, which are made of synthetic-tire-cord commonly used in tires, are arranged at ideal angles to hold the internal pressure and distribute stress evenly. So they can provide strong efficient reinforcement.Â
Â
2. General Dimensions of Airbags
Â
Diameter: 0.8m to 4m
Â
Length: 7m to *4m
Â
In order to confirm airbags safety working pressure, we define the number of layers, which means the number of synthetic-tire-cord layers. Normally we offer marine airbags with 3, 4, 5, 6, 7, 8, 9 layers. Other types are available upon request.
Â
3. Performance Calculation Principle of Airbags
Â
The bearing capacity of marine airbags was calculated based on the working pressure, contact area. Herein, working pressure was got upon the burst pressure and safety working factor.
Â
Because of the flexibility of marine airbag the contact area will be affected by some terms which include the carried ship condition, the different position from gravity center during the process of ship launching and pulling. So the bearing capacity of airbags will vary as well as the contact area.
Â
The approximate bearing capacity can be calculated as follows:
Â
F=PS
 S=π x (D*-D2)/2
