50kPa Pneumatic Rubber Fenders 3.3x6.5m 3015kN For Marine Berthing

Product Specification

50Kpa Rubber Fender For Boat Berthing 3.3 X 6.5m Pneumatic Marine Fender 

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.

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 Fender Construction

Floating pneumatic rubber fenders shall consist of an out rubber, reinforcement synthetic-tire-cord layer, and inner rubber, vulcanized firmly.

• Outer Rubber Layer for Better Protection
  The out rubber are used to protect the cord layers and inner rubber. This rubber compound have sufficient tensile and tear resistance strength to withstand anticipated weather conditions and severe usage.
• High Quality Synthetic-tyre-cord Layer
  The reinforcement synthetic-tyre-cord layer strong enough to maintain the internal air pressure of the fender. The inner rubber layer seals the pressurized air inside the fender.
• Safety Valve For Safer of Big Size Pneumatic Fenders
  Pneumatic Fenders of diameter 2500mm and larger are equipped with a safety valve for releasing excess internal pressure. Smaller fenders can be equipped upon required.
• Chain and Tire Net Pneumatic Rubber Fenders
  The outside chain and tire net provide the extra protction for the rubber fender body. We can use turck tire, fiber net, or aircraft tires. It can be changed easily.

The properties requirements of outer and inner rubber material of floating pneumatic rubber fenders comply with ISO 17357:2014.

Floating 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.

1. ISO 17357 : 2002
   All our pneumatic fenders are manufactured and tested comply with ISO 15375 latest edition.
2. Soft Reaction Force
   The reaction force does not increase sharply, even under excess load conditions. Can protect ships and mooring facilities.
3. 15° Inclined Berthing
   The pneumatic fender’s energy absorption does not decrease at inclined compression up to 15 degrees.
4. Against Shearing Force
   Fenders are adequately reinforced using strong tire-cord to cope against combined shearing forces as well as internal.
5. Lower Mooring Forces
   This fender safely protect ships and mooring facilities even under rough weather conditions.
6. Adaptable to The Tide
   Float on the water in an unrestricted vertical plane corresponding to the tidal range and ship's vertical movement.
7. 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.
8. Low Maintenance Cost
   Maintenance cost is very low. The air leakage is so minimal that it is sufficient to check the air pressure only once a year.
9. Ship Cost Minimization
   The fenders are usually packed and shipped in containers or on pallets in vacuumed and folded down state.
