China Marine Ship Launching Airbags Comply with ISO 14409. Certificated by Lr ABS CCS.

Instruction:

Evergreen ship rubber marine airbags / boat launching balloon will provide you with a unique capability of land transport very large vessels, heavy loads or heavy construction over ground where terrain would otherwise prevent such an operation. The Evergreen have wide ship rubber marine airbags / boat launching balloon in capacities from 70 tons to 380 tons per bag. Evergreen also has a selection of bags with diameters up to 2m in diameter and up to 20m in length to cover virtually all applications.The current over ground transportation capacity is 10,000 tons.

The deflated Evergreen boat launching balloon are very flat and can be placed under a grounded or stranded vessel which is hard aground. In a shipyard transportation or launching application as little as 12 inches will provide very quick placement of the Evergreen boat launching ballon under a hull. The Evergreen boat launching ballon operate with very low pressure, 7 10 PSI, which is controlled by a custom EVEGREEN designed air manifold which can operate all Evergreen boat launching ballon simultaneously or individually

All our Ship Launching Airbags are manufactured and tested comply with ISO 14409. Certificated by LR, ABS, CCS. We also can provide you the professional technical support, with our professional engineering company, Eversafe, and experienced engineers launched more than 2,000 various vessels.

Classification & Size

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' self-weight, 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 and cock
