World-leading supplIER and manufacturer
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.
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.
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.

Below are some of the most commonly-asked questions we receive regarding our fender range. Please get in touch with our expert team if you have a question that isn’t covered here.
The Yokohama pneumatic floating fender is fully compliant with ISO 17357 and PAINC 2014 standards. They’ve all been comprehensively tested for material and hydrostatic pressure irregularities and correctly evaluated for angular and durability performance. Each Yokohama fender is clearly marked with all relevant identification and fitted with radio frequency identification (RFID) as standard. Available in a whole variety of different sizes, each fender comes with up-to-date certifications.
All Yokohama pneumatic floating fenders are constructed with an inner rubber layer, this is reinforcing the cord layers and the outer rubber layer. They then have a thick outer skin which supersedes that of a normal surface fender. All fenders with a diameter of 2.5m and above are also fitted with a safety valve.
Yokohama fenders offer an outstanding return on investment due to durable and long-lasting material, this leads to low maintenance as the design withstands harsh marine environments. This gives you the confidence to guarantee the reliability, with consistent performance irrespective of age or extreme temperatures protecting ships and mooring facilities even when an excessive load is applied.
They’re also put through a rigorous testing process and each fender is fully certified by long-established and globally recognised manufacturers.
Yokohama fenders are suitable for a whole host of applications, you can use them for various ship-to-quay and Ship-to-Ship applications with different a whole host of different sizes available. They are easy and inexpensive to install with only a guy rope of a chain required. They can also easily be transferred to alternative mooring points.
Yes, all Yokohama fenders are fully compaitble with Fendercare Marine’s chain and tyre fender nets.
