Ship launching airbag 

Ship launching airbags are also named roller bags, launching air balloons, inflatable marine airbags, and air lift bags. Ship-launching airbags are made up of heavy-duty synthetic -tire cord layers with inner and outer rubber layers. It is in a cylindrical balloon shape. It helps out in floating, lifting, loading, and moving salvaging boats, and sunken ships. Rubber airbags are used for launching marine vessels.

      Airbags are made up of an outer rubber layer, multi-layer synthetic -tire cord layers, and an inner rubber layer.

Working

Ship airbag maintains high-pressure gas to stabilize the floating. The pressure of

the gas inside the airbag helps ships to float smoothly in water or on land. They use flexible airbags that enable the hull to pitch freely during the launching process to maintain a large area under the hull.  So the structure of the hull will not be damaged.

Advantages of ship launching airbags.

• Airbags help in maintaining load-bearing capacity. It also provides support

and lift to the ship.

• Ship-launching airbags have sufficient capability to deal with the resistance. 
• Ship-launching airbags are made up of flexible material so that they can adapt to different shapes and sizes according to their operation.
• Ship airbags are used to provide safety to the ships. So that they can easily move.
• Ship-launching airbags play a vital role in manufacturing, maintenance, and modification.
• It helps to reduce the contact between the ship’s slipways and docks.
• It also lowers the risk of damage to the hull.

REPAIRING OF SHIP LAUNCHING AIRBAG

Ship-launching airbags are also scratched and damaged during use and need to be repaired in time to ensure their normal use. The following process is used for repairing ship launching of airbags.

Clean and dry: first you need to clean and dry the area to process the work and to avoid impurities that affect the repair.

Point the affected area: check the surface area to find the leakage.

Polishing: polish the surface area with sandpaper to make the repair area adhere better.

Repair: Choose appropriate repair materials, such as special airbag repair glue or patches, apply or paste them correctly on the damaged area according to the instructions, and ensure that the repair material completely covers the damaged area.

Fixation: use compaction tools and heavy objects to flatten the repaired area to ensure that the repair material is fully bonded, and then wait for the repair material to dry completely. Such as done in Jerryborg Marine Ship Launching Airbags.

Inflation test: A pump or compressor is used to inflate the airbag to the proper pressure. For marine airbags, the inflation pressure is usually around 120 kph.

• Check valve and connection to function properly 
• Make sure quick-release mechanisms are operable.
• Overinflation causes airbags to burst.
• Check it is capable of holding air and maintaining it’s shape 
• The capability of floating on land and in water must be accurate.
• If airbags show minor rupture and puncture, repair in time.
• After repair check the pressure holding test. 
• An aging resistance check is used to check the material’s life and quality.
• Before releasing ship airbags to use, it is necessary to ascertain how much air pressure it sustain.

Conclusion 

Repairing a ship-launching airbag is an essential process to ensure the safety and effectiveness of the equipment. Regular inspection and prompt repairs are needed to fix any damages, such as leaks or tears, which could affect the airbag’s ability to support the ship during launch. The repair process typically involves cleaning the damaged area, applying suitable patches, and testing the airbag to confirm it works properly. By maintaining and repairing the airbag on time, we can help prevent accidents and ensure smooth and safe ship launching operations. In addition to this air airbags provide security to the language in ships. It also provides support to the ship on water to improve its working. It also provides support and protects the hull from damage. It also protects the paint of ships.
