Product Description
Ship Launching Airbags
Ship launching airbags, also known as roller bags, launching air balloons, inflatable marine airbags, air lift bags, and salvage bags, are specialized marine rubber airbags designed for launching marine vessels, ship landing, or haul-outs. These heavy-duty marine rubber airbags are constructed with synthetic-tire-cord layers and inner/outer rubber layers in a long cylindrical balloon shape.
Ship Launching Airbags Applications
- Launching marine vessels
- Ship landing and haul-outs
- Loading, floating, and moving sunken ships
- Salvaging stranded boats
Innovative Launching Technology
Marine airbags represent an innovative ship-launching technology that overcomes the limitations of traditional methods like "end-on launching", "side ship launching", and "float-out". This flexible solution eliminates the need for fixed launching tracks associated with side-launch methods.
This advanced ship launching technology is increasingly adopted by shipyards worldwide due to its significant advantages in time savings, cost efficiency, operational flexibility, and enhanced safety.
Ship Launching Airbags Structure
Our continuous innovation in design, material selection, and manufacturing processes ensures optimal flexibility, safety, and reliability in all marine airbag applications.
Proven Performance
Our ship launching airbags have successfully launched various marine vessels including:
- Cargo vessels and barges
- Chemical tankers
- Tugboats and AHTS vessels
- Floating docks
- Construction caissons
Our record includes successful launches of vessels up to 100,000 DWT using ship launching airbags.
Ship Launching Airbags Material
Our rubber airbags are constructed with an outer rubber layer, multiple synthetic-tire-cord layers, and an inner rubber layer vulcanized firmly together, with additional layers applied at the end shoulders for enhanced durability.
Inner and Outer Rubber
Both inner and outer rubber layers undergo rigorous testing to meet international standards. The outer rubber layer protects cord layers from abrasion and external forces, featuring compounds with exceptional tensile and tear strength to withstand harsh weather conditions and demanding usage.
