Fendercare D2.5L5.5m Pneumatic Rubber Fenders For Oil Tanker Transfer

Fendercare pneumatic rubber fender is installed on the dock or ship, to absorb the collision energy between the ship and the dock or ship when berthing or mooring, and to protect the ship and the dock from damage.
Pneumatic rubber fender has the advantages of low reaction force, small surface pressure and reasonable energy absorption. In berthing, the ship rolling and pitching adaptability, it will not affected by the size of the ship and is widely used for installation and maintenance convenient, especially suitable for the dock.

Structure of pneumatic rubber fender

1. Outer Rubber
Cover outside on the fender of rubber layer, which is used to protect skeleton material and inner rubber layer from damage of external force.
2. Synthetic cord reinforced rubber layer
Reinforced cord rubber layer is composed of winding synthetic cord layer, it is mainly used for maintain the internal air pressure.
3. Inner Rubber
On the ball inside the rubber layer, which is used to prevent air leakage and control the fender pressure.
4. End Flange
The metal parts at both ends of fender, which can be fitted with charging valve and safety valve

Factors on design and selection of pneumatic rubber fender

1. Maximum energy absorption
2. Reaction force
3. The distance requirements when two ships berth or one ship goes alongside wharf, including the maximum distance and the minimum distance
4. The size of vessels
5. The factors on storm from real environments and temperature changes.

Features of pneumatic rubber fender

1.Low surface pressure: with low reaction and high energy absorption rate.

2.Low transportation costs: pneumatic fenders can be deflated and folded for transport.

3.Easy operation: Easy of handling and good buoyancy, with easy installation & maintenance free.

4.Excellent performance: It is with exceptional compressibility and elasticity.

5.Application: marine fender is apt with the Large and small tides, which is suitable for areas with tidal differences.

Test of ship pneumatic fender

1. Material test for rubber
The material test of the outer rubber and the inner rubber shall be conducted in accordance with the physical properties of inner and outer rubber required by ISO 17357:2002
2.Dimensional inspection
The dimension of all the fenders shall be inspected at the initial internal pressure and the results shall be within the following tolerances:
- length: +10%, -5%;
-diameter: +10%,-5%
3.Air-leakage test
The air-leakage test shall be conducted on all the fenders at initial pressure for more than 30 min, and the test results shall
confirm that there is no air leakage.
4.Hydrostatic-pressure test
The hydrostatic-pressure test shall be performed for 10 min at the hydrostatic-pressure shown in "test pressure at 0% deflection". Maximum temporary elongation: 10%

Application of pneumatic rubber fender

1. Offshore platform
2. Oil and gas tankers

3. Fast ferries and aluminium vessels

4. Temporary and permanent installations

5. Rapid response and emergencies

6. In ports with extreme tidal variations

7. Fishing vessel, transport ship and ocean trawler

Use attention of pneumatic rubber fender

*Frequently check whether the fender body is damaged and whether the pressure is normal,and the valve core must be replaced every six moths
*The steel wire should wrap the rubber pipe,when trying steel wire to pneumatic rubber fender in case the fender is stabbed
*The surface or subject next to the pneumatic rubber fender can’t be hard and sharp-pointed in case the pneumatic rubber fender is stabbed
*The accessories and jigs nuts can’t be loose when testing the internal pressure
*The rope net should be reliable,the steel wire used for hanging metal parts and the hook link can’t be tied in disorder.
