What is Marine Yokohama Fender
The "Yokohama Type Pneumatic Rubber Fender" was developed in 1958. Progress in the development of such floating pneumatic rubber fenders is closely related to the progress and development of ship technology, and has to continuously cope with progressively larger oil tankers such as VLCC's, ULCC's, large gas carriers, bulk carriers and floating structures.
Floating pneumatic 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.
Marine Yokohama Fender layout
Pneumatic Rubber Fenders 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.
No Deterioration or Variation in Performance
Pneumatic Rubber Fenders utilize the compressive elasticity of air, therefore
performance deterioration due to fatigue is absent.
Advantages at Inclined Berthing
Pneumatic Rubber Fenders, energy absorption does not decrease at inclined compression up to 15 degrees.
Applications Of Pneumatic Fender
● Containers, tankers, LNG carriers and bulk cargo ships;
● Fast ferries and aluminum-hulled vessels;
● Tugboats & Yachts;
● Offshore platforms & other ocean platforms;
● Kinds of terminals;
● Temporary or permanent installations;
● Rapid response and emergency fendering;
● As stand-off fenders to realign ships with shore facilities.

Marine Yokohama Fender in using
Qingdao Florescence manufactures marine rubber fender with 50kPa (pneumatic 50) and 80kPa (pneumatic 80) initial pressure. The internal pressure, endurable pressure, safety-valve setting pressure and hydraulic test pressure are also in compliance with the requirements of ISO17357:2002.
Fenders of diameter 2500mm and larger equipped with safety valve for releasing excess internal pressure when the fenders are over-compressed accidentally.
