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. 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
Transportation We can take the deflation pallet transportation and the entire fender transportation without deflation according to the requirements of customers. We always put the customer's requirements first.
1. When the Pneumatic rubber fender is not used for a long time, it should be washed and dried, filled with appropriate compressed air, placed in a dry, cool, ventilated place.Inventory temperature is maintained at -15 ℃ -40 ℃ .
2 .The place where the fender is stored should be kept away from the heat source.
3 .Fenders shall not be in contact with acids, alkalis, greases and organic solvents.
4 .When the fenders are not in use, they must not be stacked and should not be stacked on the ba. In order to better extend the service life of pneumatic rubber fenders, it is recommended that you store them in strict accordance with the above recommendations.
