Marine Rubber Ship Fenders

Pneumatic rubber fenders are made of synthetic-cord-reinforced rubber sheets with compressed air inside to enable them to float on the water and work as a shock absorber between two ships (ship-to-ship), or between ships and berthing structures when they come alongside each other on the water.

Note: The floating pneumatic rubber fenders have sometimes been colloquially referred to as “Yokohama Fenders” or “Yokohama type fenders” – ISO 17357:2014 Ships and marine technology — Floating Pneumatic Rubber Fenders

Advantages of Pneumatic Rubber Fenders

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 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 Rubber Fenders Construction

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

Fenders of diameter 2500mm and larger equipped with safety valve for releasing excess internal pressure when the fenders are over-compressed accidentally. The properties requirements of outer and inner rubber material of floating pneumatic rubber fenders comply with ISO 17357:2002.

Outer Rubber

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.

Tir Cord Layers

The reinforcement synthetic-tire-cord layer strong enough to maintain the internal air pressure of the fender

Inner Rubber

The inner rubber layer seals the pressurized air inside the fender

Pneumatic Rubber Fenders Classification

Fender types:

1.Net-type Fenders: fenders that are covered by a tire chain net, each end shall be linked together with one to two ring(s).
2.Sling-type Fender: fenders that are designed to be used without a protection net.

Initial internal pressure:

1.Pneumatic fender 50 (initial internal pressure 50 KPa)
2.Pneumatic fender 80 (initial internal pressure 80 KPa)

Sling Type Fenders

Pneumatic Fenders with Aircraft Tire

Pneumatic Fenders with Truck Tire

Pneumatic Rubber Fenders Application

Floating pneumatic marine ship rubber fender could be used as a protective medium for ship-to-ship operation(STS), ship-to-quay(STQ) and ship-to-berthing(STB). And suit for various vessels, like:

Tankers, Gas Carriers and Bulk Cargo Ships;
Fast ferries and aluminum hulled vessels;
Temporary of permanent installations;
Rapid response and emergency rendering;
As stand-off fenders to realign ships with shore facilities.

Pneumatic Rubber Fender Performance

The performance of floating pneumatic rubber fenders shall be specified in terms of Guaranteed Energy Absorption (GEA), Reaction Force at GEA deflection, and Hull Pressure at GEA deflection.
