Marine Airbags for Ship Launching/Ship Pulling/Salvage
Ship launching using marine airbags is a very popular vessel launching method. It overcomes the shortcomings of the fixed launching track, which limits the productive capability of the small and medium sized shipyards. Now it has become a Flexible Launching Technology, having the merits of time and labor saving, flexibility, reliability and safety in operation and comprehensive economic benefits etc.
After years of practice and accumulation of experience, we have developed the technology from launching only 1,000 DWT ships to current 100,000 DWT ships and we will achieve more. And now this technology has become a flexible, promising, secure and mature technology. Besides that, these airbags are widely used in slipping of ships and boats of all sizes.
How It Works Using Marine Airbags for Ship Launching and Pulling
1. Place airbags under the vessel between the supporting blocks and inflate them to lift the vessel. And then remove the blocks under the vessel after lifted.
2. Adjust airbags’ pressures. Check all airbags’ working height, especially airbags at bow, if working heights are less than 0.3 m then people should adjust the airbag’s pressure to increase its working height.
3. Block launching area and prepare good communication for the launch command.
4. When water level reach desired level, cut off pulling ropes and release the vessel. If the launching water area is limited, people may use winch to release the vessel slowly into the water.
5. Reclaim airbags after launch.
Do not be misled by suppliers who supply old re-used rubber, weak
cords with lower number of true layers and more. Top quality Marine Airbags can be used up to 9 years, and in the long run, actually helps you save more!
Why Choose LUHANG Marine Airbags
Ideally, airbags should be made of new rubber material that adheres to the following standards:
The keyword here is new.LUHANG NEVER uses recycled or reclaimed rubber material in airbag production. This is a huge red flag. Quality rubber makes the foundation of the whole “inflatable roller” idea, especially when it has to bear very high values of weight on top. Recycled and reclaimed rubber have substantially lower elasticity and has a very fast ageing rate which compromises the integrity of airbags. Use these recycled rubber airbags a couple of times and you will realise they burst very easily.
On the other hand, cords play a big role, too. These “two cords” are supposed to be two-strand cords with more than 205 N strength per cord. Some manufacturers, like LUHANG, procure and use a higher strength cord (above required standard) to ensure quality strength; but some other suppliers use two-strand cords with lower strength sometimes. There is also the difference with other cords like dacron cords etc. The difference in use of raw materials can have a cost difference of more than 65%!!
Marine Airbag Specification
You can choose the required diameter and effective length to meet your projects.
★Diameter (D): from 0.5m to 5.0m.
★Effective Length (EL): from 5m to 30m.
★Total Length (TL): from 6m to 32m
The above specifications only are our standard specifications arrange. Can be supplied customized size upon customers’ request.
The number of layers, which mean the number of Synthetic-tyre-cord layer, usually, our airbags contain 3,4, 5, 6, 7, 8, 9,10 layers types. Other type is still available upon your request to confirm the Safety Working Pressure.
Imagine the shock when we encountered some customers came to us asking for a 15-layer airbag!
Most ships/structures can be handled with our 7-layer type airbags, or in some cases (sharp hull or challenging work conditions) maybe up 10 layers. But anything more than 10 is definitely not necessary. These overstatements cause industry-wide confusion, and buyers thought they are getting more with these cheap prices. However, we are convinced our LUHANG 7-layer type airbags would perform better than many of those “15-layer” airbags. Truly reputable suppliers will understand that these high layer counts mean nothing. For those “15-layer” claims, how many layers do you think you are getting?
Also, quantity is not everything. It is vital for the buyers to educate themselves of the difference in quality. And the best part is to try our products to see the difference for themselves!

LUHANG Marine Rubber Airbags Advantages
Marine rubber airbags use matters needing attention
a. Working pressure control in our safe working pressure.
b. Avoid contact with sharp objects
c. when Long time not need , should wash to dry , placed in a cool dry ventilated place . Storage place away from heat , acid and alkali , oil and grease
Third party inspection is great. Our company happily offers third party inspection certificates from various inspection parties upon customer’s request.As we have mentioned earlier, it is a combination of the finest raw materials and skilful fabrication expertise that makes a product great. The fabrication skill can’t be “inspected” and compared on a newly made product. Besides, some manufacturers like LUHANG even go above and beyond the guidelines to use much higher grade materials in our products.
A more specific example would be product lifespan: product A and product B might work the same for the first two uses, but gradually, you will realise product A degrades, loses its flexibility and strength faster; while product B maintains its performance, and has a much longer useful life. In the long term, you would save more by using product B, even if sometimes it cost a little more upfront.
LUHANG Company has been Certificated by ISO 9001:2009, CCS, BV, SGS, GL, DNV.
Passed Environment Management System Certification, and OHSMS Certification.
LUHANG Products have been approved by CCS, BV, LR, DNV, GL, ABS, V-TRUST and other third party inspector.
Qingdao Luhang Marine Airbag and Fender Company is the leading & professional & largest company that initiated airbags for ship launching in China from year of 1998. During 30 years’ development and experience in airbag production and ship launching, our ship launching airbags have become the most reliable. Since then, more cargo vessels, barges, chemical tankers, tugboats, AHTS vessels, floating docks, and even contstruction caissons have all been launched using our airbags. Aside from ship hauling & launching.
