Description

Yokohama Type Pneumatic Rubber Fender Floating Boat Bumpers

Pneumatic Rubber Fender

The pneumatic rubber fender was developed in 1958 in Japan. 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.

Pneumatic rubber fenders are used worldwide for ship-to-ship (STS) transfer operations, terminals, and for all kinds of ships, large tankers, vessels, docks, harbor wharves and ocean platforms.

Pneumatic Rubber Fender Advantages

1. Safety and Reliability

Jerryborg Pneumatic Rubber Fenders are constructed of natural rubber, 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.

2. Patented Active Protecting Safety Valve Design

All Jerryborg Pneumatic Rubber Fenders (D>2500mm) are equipped with a safety valve to release the inside air in the event of accidental over-pressure.

3. No Deterioration or Variation in Performance

Jerryborg Pneumatic Rubber Fenders utilize the compressive elasticity of air, therefore performance deterioration due to fatigue is absent.
