Collision Defense 2.5mx5.5m 3.3x6.5m Tugboat 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.

Structure pneumatic rubber ship bumper fender

1. Outer Rubber

Cover outside on the ball of rubber layer, which is used to protect skeleton material and inner rubber ball from damage of external force, the main features: high strength, wear resistance, ageing resistance and tear resistance.

2. Synthetic cord reinforced rubber layer

Reinforced cord rubber layer is composed of winding Synthetic cord layer, It is mainly used for maintain the internal air pressure, which has good elasticity, no deformation and high power etc.

3. Inner Rubber

On the ball inside the rubber layer, which is used to prevent air leakage and control the ball pressure.

4. Flange opening

The metal parts at both ends of fender, which can be fitted with charging valve and safety valve.

Features:

High energy absorption with a low reaction force
2. Light weight, portable and floatable, can be installed and replaced easily
3. Heavy duty and long service life-over 10 years
4. Supplied as sling type (body only) or with chain and tire net
for protection of the fender body
5. Suitable for locations with large and small tidal differences

Applications

1. Offshore platform

2. Oil and gas tankers

3. Fast ferries and aluminium vessels

4. Temporary and permanent installations

5. Rapid response and emergencies

6. In ports with extreme tidal variations

7. Fishing vessel, transport ship and ocean trawler

Advantages
1.Safety and Reliability

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.
Most Cost Competitive System
The utilization of the compressive elasticity of air provides completely uniform surface pressure on contact, making Pneumatic Rubber Fenders ideal. The surface pressure of the Pneumatic Rubber Fenders is equal to the internal air pressure.
Due to low and uniform surface pressure properties, the Pneumatic Rubber Fenders are popular at LNG-ship terminals.
Soft Reaction Force for Ship and Jetty Structure
The reaction force of Pneumatic Rubber Fenders does not increase sharply, even under excess load conditions. Therefore, the Pneumatic Rubber Fenders perform well in such cases, and protect ships and mooring facilities.
