Inflatable ship landing airbag also known as rubber airbag, ship air bags, ship launching airbag, ship salvage airbag, boat salvage airbags, inflatable airbag, ship lifting bag, air balloon, made by rubber & multi 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. Marine airbags are very popular with shipyard, ship owner, and marine supplies company now.

How to choose suitable ship landing rubber airbag
1.Length
Select the airbag's effective length not less than the maximum width of vessel or anything you want to move by airbags. But when you arrange two rows of airbags keep in mind to calculate the total length to avoid contact of airbags in two rows. The total length of airbags can be estimated to be effective length plus diamter. It says an airbag whose effective length is 16 meters and diameter is 1.5 m then its total length is 17.5 m.

2.Diameter
Diameter of airbag is decided by the height of your vessel's support blocks. If the support block is 1 m high, then you should choose airbag's diamter not less than 1.5 m. If you get 1.5 m high blocks, the airbag with 2m diameters will suits you well.
For air lift use, airbag's diameter or length is mainly decided by the buoyancy you need from airbag. And also consider the pressure of airbag stands if you apply airbags in deep water.
For caisson transport by marine airbags, the most suitable diameter is 0.8-1 m.

3.Layers
Launching airbag's performance is decided by its component layers. For air lift use or light vessel (launch weight).
If the ship weight below 500tons, airbag layers is 6layers or less than 6layers,based on ship type and usage frequency.
If the ship weight above 500tons, airbag layers is 8layers or more then 8layers, based on ship type and usage frequancy.
Florescence airbag layers from 3 to 10layers, customer regular layer is 4,5,6,7,8,10layers.
