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 a 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 an 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. Foam-filled fenders are floating fenders too.

Pneumatic Fenders Classification

Our pneumatic rubber fender’s internal pressure, endurable pressure, and safety-valve setting pressure are fully compliant with ISO 17357.

Fender Pressure Rating

There are two initial pressure ratings for our Pneumatic Rubber Fenders. 
    ■  Pneumatic 50 (P50, Initial internal pressure 50kPa)           
    ■  Pneumatic 80 (P80, Initial internal pressure 80kPa)    

Pneumatic Fender Type

There are two common types our Pneumatic Rubber Fenders.
■  Type I — Net Type Covered with a chain net, wire net, or fiber net for small size fenders
■  Type II — Sling Type This type of fender has a lifting device on each end, which shall be connected with a guy chain or guy-rope. Without a protection net, easy to handle with lightweight)

Pneumatic Rubber Fenders Advantages

Doowin-Marine pneumatic rubber fenders are manufactured and tested to comply with ISO 17357. Our real Yokohama-type pneumatic fenders are made by mold based on Korean production technology.

 

ISO 17357

All our pneumatic fenders are manufactured and tested comply with ISO 15375 latest edition.

Adaptable to The Tide

Float on the water in an unrestricted vertical plane corresponding to the tidal range and ship's vertical movement.

Against Shearing Force

Fenders are adequately reinforced using strong tire-cord to against combined shearing forces.

Low Cost Installation

Fender can be moored simply by means of a guy rope or chain. It can be removed easily to a suitable jetty or quay.

Soft Reaction Force

The reaction force does not increase sharply, even under excess load conditions.

15° Inclined Berthing

The pneumatic fender’s energy absorption does not decrease at inclined compression up to 15 degrees.

Lower Mooring Forces

This fender safely protect ships and mooring facilities even under rough weather conditions.

Ship Cost Minimization

The fenders are usually packed and shipped in containers or on pallets in vacuumed and folded down state.
