Mairne Airbag For Launching Ship

 

Marine Airbag for Ship Launching
Marine Airbags for Ship Launching are also known as inflatable marine airbags, roller bags, air lift bags, and salvage bags. Marine Airbags range in size from 0.8 to 2.5m diameter, with lengths of 5.0m to 24.0m 'effective length'. Marine Airbags are used for ship launching, haul-outs, loading, and floating. They are widely used in cargo boat launching and landing, lifting and moving sunken ships, and salvaging stranded boats. Air bags have the benefit of not only saving labor and time, but investment costs. Additionally they are flexible, portable, and dependable.

Ship Launching Airbags relieve the restrictions of traditional slide-board technology which is commonly used in building small or medium size ships, and it provides an economical alternative to expensive dry docks.

Air bags also allow for the landing of vessels in locations previously restricted only to dry docks. Years of trial and error with pneumatic roller bag technology has increased the ability of launching 100-ton ships to 13,500-ton ships!

 

4-layer bags that are 1.5m dia x 15m long for example contain a rubber content that is not less than 51%. The air-bags can safely hold 156-tons with a safe working pressure of 0.08MPa while rolling. When standing still the highest lifting pressure is 0.10MPa while holding 194-tons.

6-layer bags that are 1.5m dia x 15m long for example contain a rubber content that is not less than 51%. The air-bags can safely hold 234-tons with a safe working pressure of 0.12MPa while rolling. When standing still the highest lifting pressure is 0.14MPa while holding 272-tons.

When you have vessels to launch, but are not sure of the quantity and size the launching need. Please check and answer the following questions. Then we will figure out the suitable airbags:

 

1. Type of vessel?

2. LOA (length) of ship?

3. Width of vessel?

4. Vessel's actual launched weight?

5. What is the vessel's DWT?

6. Type of ground ship is built on? (Dirt, concrete, etc.)

7. Depth where the ship first enters the water?

8. What's the angle degree of slipway? (Land)

9. Please provide the low/high tide schedule at site.

10. The working height? (The block stand height)

11. Distance from bottom of propeller to the water level?

12. Distance from back of vessel to the water entry point?

*If possible, please provide photos of the launch area.
