Qingdao henger pneumatic rubber fender structure
Qingdao henger pneumatic rubber fender consists of four parts.
1. Inflatable rubber fender outer layer glue
The rubber layer covering the outer side of the fender protects the cord layer and the inner lining rubber from abrasion and other external forces, greatly improving the use mission of the product, and also increasing the durability of the product!
2. Line layer
The cord fabric made of high-quality nylon cords, each nylon cord can bear a weight of 50kgs, and each layer of cord fabric is composed of thousands of nylon cords, which greatly improves the durability of the product and also maintains the fender. The internal pressure of the product does not need to be inflated within 60 days!
3. Inner rubber
As for the lining of the rubber membrane, the content of natural rubber in our products is as high as 60%, which is more flexible and puncture resistant. At the same time, it is used to seal the pressurized air in the fender to prevent the product's internal gas from leaking!
4. Flange opening
All of our products are equipped with safety valve devices for the steel flanges installed on the mudguards. After the product is under unbearable pressure, the safety valve opens automatically to prevent product damage.
1. Guaranteed energy absorption
2. Chain tyre net and sling type
3. Thick skin construction
4. Good angular performance
5. Less surface pressure onto the side wall of ships. (The capability of accepting surface pressure of the fender is up to 14 ton/m2).
6. No reduction on the performance of compression when inclined.
7. Suitable for areas with large or small tides.
8. Suitable in cold weather because the compressed air as buffering medium.
9. Especially in mooring of large scale ships in sea docks and lightering.
10. Maintains large clearances between hull and structure
1. Oil and gas tankers
2. Fast ferries and aluminum vessels
3. Temporary and permanent installations
4. Rapid response and emergencies
5. In ports with extreme tidal variations
6. For ship-to-ship lightering operations
7. For all navy vessels due to low hull pressure and the advantage of a proportional increase of reaction force and energy absorption
1. large crude oil carrier, VLCC
2. container vessel
3. offshore sea task platform
4. large shipyard and dock
5. large ship and cruise ship
6. army harbor dock
7. large bridge pier
Pneumatic Rubber Fender is constructed of synthetic-cord-reinforced rubber sheets with compressed air inside to keep floating over the water surface and work as a shock absorber between two ships or between ships and berthing structure when they come alongside each other on the water.
Pneumatic Rubber Fender is a leading anti-collision device for marine application in the world today. Pneumatic Fender has become an idea ship protection medium used extensively by large tankers, LPG vessels, ocean platforms, large docks, harbors and wharves.
Pneumatic Rubber Fenders are suitable for many applications including:
1. Tankers, Gas Carries and Bulk Cargo Ships;
2. Fast ferries and aluminum hulled vessels;
3. Temporary of permanent installations;
4. Rapid response and emergency fendering;
5. As stand-off fenders to realign ships with shore facilities.
4. Product Applications
The are two typical installation type: ship to ship operation and ship to dock operation.
a. ship to ship operation
Generally speaking, two contact points are enough for the light duty ship to ship operation. But 1 or 2 extra pneumatic rubber fender should be used as the primary fender to absorb the berthing energy for the heavy duty ship to ship operation, and keep proper stand-off distance between two ships. Meanwhile, two or more small-size fenders can be hung on the ship hull as the secondary fender.
b. ship to dock operation
Pneumatic fenders are often used for the ship to quay operation because of its excellent performance. The pneumatic fenders are anchored with quay by the guy chain and shackles. Meanwhile, the pneumatic fender can be floated on the water surface depend on the change of tide.
1. Safety and Reliability
Boat Rubber Fender are constructed of several layers of strong tire-cord, and are thus resistant to pressure and cutting. The safety factor adopted in the design of this fender is based on accepted theory and has been proven by extensive experimentation. large-size fenders are equipped with a safety valve to release the inside air in the event of accidental over-pressure.
2. No Deterioration or Variation in Performance
Boat Rubber Fender utilize the compressive elasticity of air, therefore performance deterioration due to fatigue is absent.
3. Advantages at Inclined Berthing
Boat Rubber Fender, energy absorption does not decrease at inclined compression up to 15 degrees.
4. Most Cost Competitive System
The utilization of the compressive elasticity of air provides completely uniform surface pressure on contact, making Boat Rubber Fender ideal. The surface pressure of the Boat Rubber Fender is equal to the internal air pressure. Due to low and uniform surface pressure properties, the Henger Pneumatic Rubber Fenders are popular at LNG-ship terminals.
5. Soft Reaction Force for Ship and Jetty Structure
The reaction force of Henger Pneumatic Rubber Fenders does not increase sharply, even under excess load conditions. Therefore, the Boat Rubber Fender perform well in such cases, and protect ships and mooring facilities.
6. Lower Mooring Forces under Rough Weather Conditions
The reaction force and deflection of Boat Rubber Fender do not easily reach the maximum because the reaction force increases slowly and allowable deflection is wide. Thus, the Henger Pneumatic Rubber Fenders safely protect ships and mooring facilities even under rough weather.
