Net-type Pneumatic Fenders

Miscellaneous YOKOHAMA FENDERS

Pneumatic rubber fenders are commonly used for ship to ship and ship to dock berthing operation. The fender has an elliptical body which consist of inter rubber layer, a synthetic tyre-cord layer for reinforcement and outer rubber layer.

The fenders also have a tire-net outside the fender body to provide protection and better resistance to operational damage.

The best feature of pneumatic rubber fender is easy to install, easy to re-deploy. The fender is supported by the water on which it floats. It can be moored simply by means of a guy rope or chain and can be removed easily to a suitable jetty or quay when not in use, or transferred to another mooring point whenever required.

All Fender Service pneumatic fenders are produced in accordance to ISO17357-1:2014, which is the newest standard of high-pressure pneumatic fenders. ISO17357-1:2014 “Ships and marine technology - Floating pneumatic rubber fenders - Part 1: High pressure”.

This certification ensures the standard of the products, such as design, material and the performance test every fender has undergone, to ensure the overall quality of the product.

We also offer custom designed fenders, which fits every need. This includes decisions on tire-nets (aircraft/truck etc.), max inner pressure levels, and which material is preferred on chains.

All these factors affects the final performance and price of each fender.
