Description

Boat Rubber Pneumatic Yokohama Type Marine Fenders

Marine Fender

The marine fender was developed in 1958 in Japan. The marine fenders should be manufactured according to ISO 17357. The standard defines the corresponding international standards for the materials and testing of these fenders. In most cases, marine fenders should be surrounded by a tire and chain net for additional protection.

Marine fenders are extensively used for ship-to-ship (STS) transfer operations, terminals, and for all kinds of ships, large tankers, vessels, docks, harbor wharves and ocean platforms.

Marine Fender Advantages

1. Safety and Reliability

Marine fender is made of several strong cord layers to enable it to be pressure-resistant and puncture-resistant.

2. Advantages at Inclined Berthing

Compared with solid fender and foam fender, the marine fender is easier to distribute the load along the ship body or berthing structure.

3. Lower Reaction Force with Excess Load

When the marine fender receives excess load suddenly, it can still perform well. The reaction force will not increase sharply compared with solid fenders as follows.
