Instruction
EVERGREEN-Maritime is the Pioneer and leader of Marine Airbags and sets the standard in the industry.
After there decades development and practice, we have developed this technology from launching only 1000 DWT ships. And now this technology has become into a flexible, promising, secure and mature technology.
Besides ship launching, the versatile Marinetime Airbags are widely used for sunken ship salvage and refloatation, heavy lifting and shifting.
Advantage of Evergreen marine air bags
1, Advanced framework design.
2. Over 20 years' exprience in marine airbags, more improvements are reflected in production.
3. High strength synthetic-tyre-cord-layers, high construction performance.
4. Anti-aging, durable practical.
5. Hydrostatic presure test.
6. More flexible, easy installation.
7. Good airtightness safty and reliability.
8. Economical, Good after service.
9. All the products were manufactured with our responsibility.
10. Good technical supports
11. We can sign the contact for quality and after sale service.
Actually, our company is of strongpoints in ship launching airbags. Please refer to the link http://marinefender.en.made-in-china.com.
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.
