80kpa Net Type Docking Ship Protection Yokohama Rubber Fenders
Product Introduction
Yokohama rubber fenders are used world wide for ship-to-ship (STS) transfer operations, terminals, and for all kinds of ships. Since its creation until today, more than millions of fenders have been supplied worldwide both for ship-to-ship and ship-to-dock (STD) operations serving our valuable customers. These fenders play a critical role in the safe operation of ship berthing and mooring.
The advantages of the Yokohama Rubber Fends:
1. Guaranteed energy absorption
2. Thick skin construction
3. Good angular performance
4. Less surface pressure onto the side wall of ships. (The
capability of accepting surface pressure of the fender is up to 14
ton/m2).
5. No reduction on the performance of compression when inclined.
6. Especially in mooring of large scale ships in sea docks and
lightering.
