Marine airbag for ship launching
1. We are the pioneer and leader of marine airbag for ship launching, we make the marine airbag for ship launching totally according to the industry standard ISO14409: 2011.
2. Application of marine airbag for ship launching.
Now the marine airbag for ship launching are widely used for hoisting and transporting heavy structure, refloatation, salvaging sunken ship or heavy immersed steelstructure, erecting floating bridge or pipeline in the marine field and shipyards.
3. Size of marine airbag for ship launching
A. Diamter of marine airbag for ship launching:
The diameter of air bag varies such as 0.8m, 1.0m, 1.2m, 1.5m and 1.8m, etc
B. Length of marine airbag for ship launching:
The length of air bag is to be specified by the customers, importers, or distributors.
C. Layer of marine airbag for ship launching:
The layers of air bag contains 4, 5, 6, 7, 8, 9, 10 layers.
4. Materials of marine airbag for ship launching:
An marine airbag for ship launching is to be constructed of an outer rubber layer, one or more synthetic-tire-cord layers, and an inner rubber layer.

Classification & Size
It is easy to choose suitable airbags by yourself. Standard specifications of Evergreen shipping air bags. We can manufacture as clients' request.
1. Standard size of marine airbags:
Diameter (D): From 0.8m to 2.0m.
Effective Length (EL): From 6m to 18m.
Total Length (TL): From 7m to 19.5m
2. Standard number of layers:
Evergreen airbags are widely used for marine engineering projects: Ship launching and hauling out, heavy lifting and transportation, ship salvage, etc. Those application are found to be cost-effective and convenient.
Available diameters and lengths of Evergreen airbags range from 0.8 to 2.0 m and 4-22 m, respectively. Ragular airbag plies are 4, 5, 6, 7, 8.
The technology of ship launching with air bags developed from small flat bottom ship of several ten tons to good-sized, complicated, high value added ships and blazed a successful one for its own development road.
The practice proves that the ship whose DWT exceed 50, 000 tons launched by air bags is feasible as the advancing of manufacture technology of intensive air bags and the design of slipways. To launch ships DWT more than 50, 000 tons people must consider the following measures:
Take more care of the design of air bag ship launching slipway which has the higher demand of the degree and degree variety.
Basing on the ships' selfweight, center of gravity, the form of ship bottom, degree of slipways, water level, people should calculate every motion of the ship during the launch process to testify the rationality of air bags positions.
People should pay more attentions to calculate the ship stree and inner pressure when the stern drops.
