 Marine Airbags Ship Launching  Salvage Air bags

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 n Brazil, Indonesia Shipyard especially for barges launching, pull to shore, vessels' haul out and ship landing work.

2.Comparison with other Launch Way

Rollers Bag is a innovative ship launching technology, comparing with "end-on launching", "side ship launching", "float-out". This ship launching technology overcomes the restrictions of fixed launching track of side-launch. Ship launching airbags are accepted by more and more shipyards world wide due to its advantages of saving time, saving investment, flexible, safety. The biggest vessel launched by ship launching airbags up to 100,000 DWT.

4.Classification of Roller Marine Air Bags

Ship launching marine airbags are categorized by "ordinary airbags", "high-bearing capacity airbags", and "Super-high-bearing capacity airbags" according to the bearing capacity.

  • QP Ordinary airbags - the air bag with 3, 4 or 5 layers of cord fabric 
  • QG High-bearing capacity airbags - the air bag with 6, 7 or 8 layers of cord fabric
  • QS Super-high-bearing capacity airbags - the air bag with 9, 10 or more layers of cord
