Yokohama pneumatic floating fenders

The durability and life expectancy of Yokohama's floating pneumatic fenders provides owners with an outstanding return on investment.

Supplied by Fendercare to protect ships and mooring facilities, Yokohama fenders, which have been used effectively for worldwide ship-to-quay and Ship-to-Ship applications since 1958, are proven to perform safely even when excess load is applied to them.

Yokohama fender durability

Constructed using several layers of strong tyre cord arranged at optimum angles, Yokohama's floating fenders are designed to distribute load and stress evenly. Extremely resistant to pressure and cutting, they are able to withstand abrasion during adverse weather conditions meaning they are ideally suited to harsh marine environments. Larger sized fenders also come fitted with a safety valve as an added precaution to prevent accidents in the event of over compression.

Yokohama fender performance

Reliant on the compressive elasticity of air, Yokohama pneumatic fenders show no deterioration or variation in performance due to fatigue or extremely low temperatures (-50°C and below) thereby negating the need for owners to make regular replacements.

Installation is simple and inexpensive, as the fender is supported by its own weight in the water. As such, it can be moored easily by means of a guy rope or chain, and can be removed with ease for transfer to another mooring point.

Whilst some manufacturers of pneumatic fenders claim compliance with the internationally recognised ISO 17357 manufacture, testing and performance standards, despite failing to meet certain key criteria, Yokohama affords customers complete confidence by demonstrating full compliance with PIANC 2002.
