Description

Floating 80 50kpa Pneumatic Fender for Ship Vessel with Chain Net

Pneumatic Fender

The pneumatic fender was developed in 1958 in Japan. Progress in the development of such floating pneumatic 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.

Since pneumatic fender's creation until today, these pneumatic fenders play a critical role in the safe operation of ship berthing and mooring.

Pneumatic Fender Structure

①. outer rubber layer

Pneumatic fenders are covered by the outer layer made of natural rubber. This rubber compound is strong enough to protect the inner layer and synthetic-cord layer from the damage of external forces and severe weather conditions due to its high elasticity and abrasion resistance.

②. synthetic-tire-cord layer

The synthetic-tire-cord layer is made of synthetic-tire-cord fabrics, compared with synthetic canvas fabric and synthetic belt fabric, this reinforcement layer performs better in fatigue-resistance and pressure-holding.

③. inner rubber layer

The inner layer is designed to seal the air inside the fender.

Pneumatic Fender Advantages

1. Advantage Under Severe Weather Conditions

Under normal circumstances, the ship movement caused by high and long-period waves or strong wind will bring repeated compression and shearing forces on the fender and make it easier to be fatigue and damage. However pneumatic fender is strong enough to resist severe weather conditions, the reaction force increases slowly compared with solid fender and won't easily reach the maximum.

2. Tide Adaptation

Pneumatic fender is filled with pressure air inside that makes it flexible and easy to float on the water and adapt to the tide variation.

3. Safety and Reliability

Pneumatic Fenders are constructed of natural rubber, several layers of strong tire-cord, and are thus resistant to pressure and cutting. The safety factor adopted in the design of this fender is based on accepted theory and has been proven by extensive experimentation.
