Nanhai NO.1 8 Layers Rubber Marine Salvage Airbags with CCS Certificate


Reference for Marine Airbag selection

There are two industrial standards for Marine Airbags in China.: one is product standard named "Air bag for ship up to or down to launching way "; another is technology standard named "Technological Requirements for ship Upgrading or Launching Relying on Air-bags".The latter offer the basic calculation of marine airbags employed in a marine project.

According to Chinese industrial standards people will know the approximate quantity and specifications of marine airbags needed for their projects then consult the manufacturer to confirm the design. There maybe optional specifications to be selected for a specific marine project and a good manufacturer should know the best choice. The data of marine airbags' blasting pressure will reveal the product's quality level. For top quality marine airbags, such as one 1.5 m diameter and 7 m length Evergreen marine airbag, the blasting pressure is 0.67 Mpa which indicates the safe coefficient is more than 5 considering its 0.12Mpa working pressure.

Full technical service is the qualification of a good company. Although general calculation formula or performance data of marine airbags can be got from most factories but detailed calculations based on mathematic model and experience is more important to the success of marine projects.

In a word

Good selection of marine airbags is vital for the success of marine projects. Get basic knowledge of marine airbags selection then consult with manufacturers can help people complete projects in shortest time.


Airbags Used In Marine Launching Specifications:

1. Calculated prepare enough rolling the balloon and the balloon and the traction winch, air compressor, etc.Should be subject to no-load inflatable balloon before using detection (inflation pressure is 1.25 times the safe working pressure), found that after the leakage phenomenon should be repaired in use.

2. Arrange the ship after the road, including berth to ramp.Must level off, remove impurities, pay special attention to hard nails on the ground, with a mouth stones must dig clean, prevent punctured balloon, ramps should have enough length and depth in the water.

3. Will all the outstanding Angle on the bottom plate, beauty and stern castings such as burr should be smooth.

4. The traction winch wire rope hull.

5. Close all sea valves, fixed the rudder and propeller.

6. Dismantle all block, fill in the rolling airbags

7. Adjust the gasbag internal pressure, make the bottom down to the appropriate work height, don't touch the ground, keep moving ship process generally small boat desirable between 0.2-0.3m.

8. All the airbag should be aimed at hull center respectively, and the vertical direction of water

9. Start the traction winch slowly released cables from hull began to move, when the first a bag from the top bottom immediately after carried to the tail, and put in the book bag planned spacing feeding airbags.

10. Repeat the above process, and gradually move the boat to the water, when not feeding balloon blockade river barred to ship.

11. Relocated, inform the staff on board ready, when the condition such as water depth enough, ordered the wire rope or decoupled fast launching ship.If the river is very narrow water fast enough, can use slow winch cable, let the boat slowly into the water.

12. Is necessary for some of the larger ships, should install slide device.

13. Recycle bag
