2m x 12m Heavy Duty Ship Launching Rubber Airbags Used in Shipyards
A more and more popular way of launchig ship with rubber airbags
Ship launching rubber airbags are very powerful and versatile tools for marine launching projects. They widely used for ship launching and docking in shipyards, specially medium and small shipyards alongside rivers and seasides in Asian and American countries. Ship launching airbags indicate the most popular application of these heavy duty airbags is for ship launching. It is estimated that more than 80 percent new built ships who’s DWT below 60,000 are launched by ship launching airbags.
How to select marine airbags for ship launching and docking
Ship launching airbags can be made into various sizes and layers accoding to the ship size and weight and the launching or docking conditions.
| Size | Diameter | 1.0m, 1.2m, 1.5m, 1.8m, 2.0m, 2.5m, 2.8m, 3.0m |
| Effective Length | 10m, 12m, 15m, 18m, 20m, 22m, 24m, etc | |
| Layers | 4 layers, 5 layers, 6 layers, 8 layers, 10 layers, 12 layers |
Effective length and diameter : The effective length should be same as the ship breadth, or 1 meter shorter than the breath.
We can make airbags in length from 5m to 24m.
Diameter : Select diameter based on the ship size and work requirement. Select bigger airbags for large ships, but smaller airbags for small boats. In case the ships need cleaning or repairing bottom, choose bigger airbags so that workers can work in a more comfortable posture under the ship. Diameter of 1.5m, 1.8m, 2m or 2.5m are all suitable and available for large ships.
The number of layers : The more layers the airbag has, the bigger bearing capacity it has. To lift a ship to a certain height, enough airbags with enough layers are needed. Generally speaking, airbags with 6 layers are enough for most engineering works. Only in some rigorous situation, airbags will need 7-8 layers to enhance its performance. For example, if people use airbags to lift heavy caisson but their contact area is limited, and then airbags will need higher pressure and more plies to ensure the safety.
Good selection of marine airbags is vital for the success of marine projects. Get basic knowledge of marine airbags selection then consult with manufacturers can help people complete projects in shortest time.
Below is a chart for the bearing capacity of several sizes
| Model | Dia | Effective Length | Overall Length | Cord Layer | Rubber Plate | Thick-ness | Working Pressure | Bursting Pressure | Lifting Height | Bearing Capacity | |
