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.

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.

Features of Yokohama pneumatic floating fenders:

  • Fully compliant with ISO 17357 and PIANC 2014 standards
  • Comprehensively tested for material and hydrostatic pressure irregularities
  • Correctly evaluated for angular and durability performance
  • Clearly marked with all relevant identification
  • Fitted with radio frequency identification (RFID) as standard
  • Complete with up-to-date certification
  • Available in a variety of sizes
  • Constructed with an inner rubber layer, reinforcing cord layers and outer rubber layer
  • Thick outer skin supercedes that of a normal surface fender
  • Fitted safety valve for fenders of 2.5m diameter upwards
  • Compatible with Fendercare Marine's chain and tyre fender nets

Benefits of Yokohama pneumatic floating fenders:

  • Outstanding return on investment due to durable and long-lasting material
  • Justified reassurance: rigorously tested, fully certified products from long-established and globally recognised manufacturer
  • Low maintenance required as design withstands harsh marine environments
  • Protects ships and mooring facilities even when excess load is applied
  • Guaranteed reliability - consistent performance irrespective of age or extreme temperatures 
  • Suitable for various ship-to-quay and Ship-to-Ship applications with different sizes available
  • Easy and inexpensive to install with only a guy rope or chain required
  • Easily transferrable to alternative mooring points
  • Quickly identifiable with complete markings and radio frequency identification (RFID) tagging
