Floating pneumatic rubber fenders are known as Yokohama fenders or Yokohama-type pneumatic fenders. Floating pneumatic rubber fenders are made of the synthetic-cord-reinforced rubber sheet with compressed air inside. The insider air can enable it to float on the water and work as a shock absorbed between two ships (ship-to-ship), or between ships and berthing structures when they come alongside each other on the water. All Doowin Marine Yokohama type floating pneumatic rubber fenders are manufactured and tested fully compliant with ISO 17357
Floating pneumatic rubber fenders can be easily handled and installed with guy-rope or guy-chain because of their lightweight. It can resist the shearing force and maintain energy absorption level under inclined compression up to 15 degrees. Meanwhile, provide low and comparatively even hull pressure.
Consisted of several synthetic-cord layers and tough abrasion-resistant rubber, they have consistent performance even under rough conditions and cyclic load. The maintenance cost and damage risk are minimized too. The best material also ensures self-buoyancy and extremely long service life.
Pneumatic fenders are available from 500 mm to 4,500 mm in diameters, and from 500 mm to 9,000 mm in length. All sizes of pneumatic rubber fenders are available as sling-type or with a heavy-duty chain & tire net. We also supply vertical hydropneumatic fenders for submarines.
Note: The floating pneumatic rubber fenders have sometimes been colloquially referred to as “Yokohama Fenders” or “Yokohama type fenders” – ISO 17357:2002 Ships and marine technology — High-pressure floating pneumatic rubber fenders.
Floating pneumatic rubber fenders shall consist of an out rubber, reinforcement synthetic-tire-cord layer, and inner rubber, vulcanized firmly.
The properties requirements of outer and inner rubber material of floating pneumatic rubber fenders comply with ISO 17357:2014.
The wrapped pneumatic rubber fenders are made by integral winding technique. The fender’s surface isn’t not so smooth similar with molded pneumatic fender. But its performance meet the request of ISO 17357. The price is much lower too. The wrapped pneumatic rubber fenders have sling type, chain and tire net type. We can equip the truck tire or aircraft tire on the fender’s body.
The molded pneumatic rubber fenders are made by mold different from the wrapped fenders. This production technology is similar to Yokohama Rubber. The fender’s surface is very smooth. Its performance is better with longer lifespan. Its price is higher too. The molded pneumatic rubber fenders have sling type, chain and tire net type. We can equip the truck tire or aircraft tire on the fender’s body too.
We make floating pneumatic rubber fenders with 50kPa (pneumatic 50) and 80kPa (pneumatic 80) initial pressure.
Our pneumatic rubber fender’s internal pressure, endurable pressure, safety-valve setting pressure are fully compliant with the requirements of ISO 17357.

We have a branch plant in Malaysia. Can provide the repair services for your pneumatic rubber fenders of neighboring countries, Yokohama fenders, like change tires, repair fender body, and end fittings.
ISO 17357-1:2014 specifies the material, performance, and dimensions of low-pressure floating pneumatic rubber fenders, which are intended to be used for the berthing, and mooring of a ship to another ship or berthing structure. It also specifies the minimum test and inspection procedures for floating low-pressure pneumatic rubber fenders.
ISO 17357-1:2014 does not address the methods for selecting the correct fender type or any safety hazards associated with its use.
The pneumatic fenders have sometimes been colloquially referred to as “Yokohama fenders” or “Yokohama type fenders”. Because the Yokohama pneumatic fender was developed in 1958 by Yokohama Rubber Co.,Ltd based on their rubber technology for automotive tires and rubber aircraft fuel tanks. It is the initial maker of this type pneumatic fenders.
Pneumatic fenders can be produced using different methods and each has its own advantages. The most common methods are molded and wrapped. Our pneumatic fenders are made by whole-wrapping technology. We donot use model to produce. But its performance reaches ISO 17357. And its cost is lower.
Our warranty period is 24 months. During this period, if there is any quality problem under the correct use and storage, we promise to change and repair them for free.
Normally, we provide the manufacturer certificate free of charges. We also can provide the BV, LR, ABS, CCS third party certificate upon the client's request. The inspection fee is charged by day.
