Product Description

Product Description

Floating pneumatic rubber fenders are known as Yokohama fenders or Yokohama-type pneumatic fenders. Floating pneumatic rubber fenders is made of the synthetic-cord-reinforced rubber sheet with compressed air inside to 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 the 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.

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.

Fenders Constructions

Pneumatic Fender Constructions

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.

• ISO 17357-1:2014 Ships and marine technology - Floating pneumatic rubber fenders - Part 1: High pressure
• ISO 17357-2:2014 Ships and marine technology - Floating pneumatic rubber fenders - Part 2: Low pressure

1. Outer Rubber Layer for Better Protection

The out rubber is used to protect the cord layers and inner rubber from abrasion and other external forces. This rubber compound has sufficient tensile and tear resistance strength to withstand anticipated weather conditions and severe usage.

2. High-Quality Synthetic-tyre-cord Layer

The reinforcement synthetic-tire-cord layer strong enough to maintain the internal air pressure of the fender. The inner rubber layer seals the pressurized air inside the fender.

3. Safety Valve For Safer

Pneumatic Fenders of diameter 2500mm and larger shall be equipped with a safety valve for releasing excess internal pressure when the fenders are over-compressed accidentally. Fender which is smaller than 2500mm in diameter, can be equipped with a safety valve if required.

4. Chain and Tire Net Pneumatic Rubber Fenders

The outside chain and tire net provide extra protection for the rubber fender body. It can be changed easily.
