Customer Reviews

I’m late in sending this, but wanted to thank Jerryborg Marine for the great job they did on the pneumatic fenders that they fabricated for me. They work perfectly and serve a long time. Very glad I found them.

—— Deepark-Dolphine Rubber

The guys over at Jerryborg Marine not only provided quick estimates, an honest timetable, and professional courtesy, but also quality work that exceeds their fair pricing. I recommend them for anyone's next project.

—— Thanh Dong-Vietnam Ecomarine

I choose Jerryborg Marine because I simply could not find any other provider that offered all the marine products I needed under one platform, such as pneumatic fenders, anchors, chains, steel wire ropes, shackles.

—— Alessandro Bitocchi-PSG AB

I have a problem with products from another vendor. The engineer of Jerryborg Marine is very enthusiastic and helps me a lot to solve the problem. I really appreciate their professional work and experts team.

What’s Yokohama Pneumatic Fender?

Marine rubber bumper is an upgraded product of boat fender widely used worldwide, which is filled with high pressure air to withstand berthing impacts. Compared with normal elastic rubber fenders (such as waste tires, solid rubber fenders, etc.), it has high guaranteed energy absorption, low surface impact, combining high abrasion resistance with low friction and quick installation. Since its application, pneumatic rubber fender has been used as a buffer due to its high performance, and it has been widely used in ship-to-ship operation and ship-to-jetty operation.

Safety and Reliability

Yokohama 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. Operational experience over a long period of time attests to its high safety and reliability, and hydraulic pressure tests have proven the strength to be suitable. Furthermore, large-size fenders are equipped with a safety valve to release the inside air in the event of accidental over-pressure. The figure below shows data obtained from many destructive pressure tests at various percentage compressions. Such data are used to establish a basic minimum endurable pressure (MEP) curve for pneumatic rubber fenders.

Advantages at Inclined Berthing

Ships usually make initial contact with the dock or another ship on STS operations at an oblique angle. In the case of solid rubber fenders or foam fenders, rated reaction force and energy absorption decreases considerably at inclined compressions compared with parallel compression. In order to compensate for the decrease of energy absorption at inclined compression, it is necessary to use larger sizes in the case of solid rubber fenders or foam fenders.

Adaptable to the Tide

Yokohama Pneumatic Rubber Fenders basically float on the water in an unrestricted vertical plane corresponding to the tidal range and ship's vertical movement. This means that energy absorption always takes place at the most suitable position, and that only one fender is required per dolphin.

Applications

►In ports with extreme tidal variations
►Ship-to-ship operations
►Oil & Gas (typically FSRU)
►Temporary berthing
