Inflatable rubber fender for SIS and STD, can be used as submarine fender

Pneumatic Rubber Fenders

The "Yokohama Type Inflatable Rubber Fender" was developed in 1958. Progress in the development of such floating inflatable rubber fenders is closely related to the progress and development of ship technology, and has to continuously cope with progressively larger oil tankers such as VLCC's, ULCC's, large gas carriers, bulk carriers and floating structures.

Floating Inflatable Fenders are used world wide for ship-to-ship (STS) transfer operations, terminals, and for all kinds of ships. Since its creation until today, more than millions of fenders have been supplied worldwide both for ship-to-ship and ship-to-dock (STD) operations serving our valuable customers. These fenders play a critical role in the safe operation of ship berthing and mooring.

Advantages of Floating Pneumatic Rubber Fenders

Floating pneumatic rubber fenders can be easily handled and installed with guy-rope or guy-chain because of its light weight. It can resist the shearing force and maintain energy absorption level under inclined compressionup to 15 degrees. Meanwhile, provide the low and comparatively even hull pressure.

Consisted of several synthetic-cord layers and tough abrasion resistant out rubber, they have consistent performance even under rough condition and cyclic load. The maintenance cost and damage risk are minimised too. The best material also ensure the self-buoyancy and extremely long service life.

Floating Pneumatic Rubber Fenders Requirements Construction features

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

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

Pressure requirements of floating pneumatic rubber fenders

Evergreen-Maritime make floating pneumatic rubber fenders with 50kPa (pneumatic 50) and 80kPa (pneumatic 80) initial pressure. The internal pressure, endurable pressure, safety-valve setting pressure and hydraulic test pressure are also in compliance with the requirements of ISO 17357:2002.

Test and Inspection for Commercial Floating Pneumatic Rubber Fenders

Acceptance testing and inspection for purchased floating pneumatic rubber fenders shall be based on the tests and inspections indicated below:

Parallel compression test of pneumatic rubber fendersMaterial test of rubber — Conducted in accordance with the Physical properties of inner and outer rubber required by ISO 17357:2002

Dimensional inspection — shall be inspected at the initial internal pressure. Tolerance: +10%, -5%.

Air-leakage test — shall be conducted at initial pressure for more than 30 min

Hydrostatic-pressure test — shall be performed for 10 min at the hydrostatic pressure shown in “test pressure at 0% deflection”. Maximum temporary elongation: 10%

Floating 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.
