Product Overview

Pneumatic Rubber Fender

The pneumatic fender is also known as the Yokohama fender. Tankers’ Ship-to-ship (STS) operations mostly uses this type of self-floating, long useful life fender. Industry-wide known as pneumatic fenders, but why are they also called Yokohama fenders?
 
Yokohama was the first company to design such fenders. Hence the name. The traditional method is to find and use dead whales as large fenders for bigger ships. After the World-War II, many turned to find a better, more constant man-made equipment since the usage of dead whales has many downsides to it. Rubber was thought to be a excellent material. 
 
So being the most trusted rubber tire manufacture in Japan at the time, the ‘Yokohama’ company was approached to design up a suitable solution. The first big issue was that making a fender straight-up using rubber would be too costly. Projected costs make it impossible to achieve. The company managed to eventually come up with the idea of using the principles of pneumatic. Pressurised air absorbs energy well enough with a reasonable reaction force. Now, commonly the working pressures of pneumatic fenders use are 50 kPa and 80kPa.
 
The story of the origin of these fenders is indeed a very interesting development of the industry. Today, these awesome low-cost, low-maintenance fenders are governed by ISO Standard. ISO 17357 consists of the two parts, high pressure and low pressure. Under the general title Ships and marine technology — Floating pneumatic rubber fenders. ISO17357:2014 is the latest version of the standard. It specifies the material, performance, and dimensions of floating pneumatic rubber fenders. Our company's pneumatic fenders are also produced and tested strictly in accordance with ISO17357:2014 standards.
 
Now the property of pneumatic fenders are low reaction force at low deflection, which made them are the most suitable fender for liquid cargo vessels and defense vessels with sensitive equipment, it also has become an ideal ship protection medium used extensively by large tankers, LPG vessels, ocean platforms, etc.
