Product Description

Ship Launching Airbag for USA, Paraguay Shipyard

 

1.Usage of  Marine Airbags
Ship Launching Marine Airbags, also known as roller bags or ship launching rubber balloon, are made of heavy-duty synthetic-tire-cord layers with inner and out rubber layers in long cylindrical balloon shape. Marine Airbags for Ship Launching and Dry Docking for barge can be used for  Shipyard especially for barges launching, pull to shore, vessels' haul out and ship landing work.


 

2.Construction Features

Marine rubber airbags' body include outer layer ,inner layer and synthetic-tire-cord layer.
All the accessories are free for our clients.

How to select airbags?

Diameter (D)          : From 0.8m to 2.5m.
Effective Length (EL) : From 6m to 25m.
Total Length (TL)     : From 7m to 27.5m

Standard number of plies (layers)

We define the number of layer, which means the number of Synthetic-tyre-cord layer, in order to confirm the Safety Working Pressure. Normally, Evergreen Ship Launching Airbags include 4, 5, 6, 7, 8 layers types. Other types is available upon clients' request.

Synthetic-tire-cord of Evergreen Ship Launching Airbags

There're two kinds of synthetic-tire-cord because of the different performance

Principle for marine airbag selection 
In fact it is easy to choose suitable airbags by yourself

Length
Select the airbag's effective length not less than the maximum width of vessel or anything you want to move by Ship Launching 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 anShip Launching Airbag whose effective length is 16 meters and diameter is 1.5 m then its total length is 17.5 m.
 
Diameter
Diameter of Ship Launching Airbags 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. 
Foe caisson transport by marine airbags, the most suitable diameter is 0.8-1 m.

Plies/layers
Ship Launching Airbag's performance is decided by its component plies. For air lift use or light vessel (launch weight below 2000 tons) launch,mid-pressure airbags are enough. For heavy duty work, the high pressure airbag should be selected. Generally speaking, airbags with 6 plies are enough for most engineering works. Only in some rigorous situation, airbags will need 7-8 plies to enhance its performance. For example, if peole use airbags to lift heavy caisson but their contact area is limited, then airbags will need higher pressure and more plies to ensure the safety. 

5.Testing and Quality:

We are very focused on the quality and invest advanced inspection equipment. 100% inflatable rubber airbags, hould be tested and inspected as per the requirement of CB/T 3795. Non conformed products are immediately rejected by Quality Control. The widely usage have been tested under rough condition. Our many satisfied customers are our best reference.

Evergreen welcomes inspection by its customer's quality assurance departments and to their appointed agencies as CCS, Lloyd's, DNV, or ABS.
