    Pneumatic fenders are ideal for permanent and semi-permanent port applications and for offshore ship-to-ship transfers. They are supplied in a wide range of sizes and in standard or high-pressure versions. Smaller fenders can be supplied as Hook type. Larger fenders are commonly fi tted with a chain-tyre net (CTN) for added protection. For navy ships, a grey body is also available.

    FeaturesEasy and fast to deploy Very low reaction and hull pressure Suitable for small and large tidal rangesMaintains large clearances between hull and structure

    ApplicationsOil and gas tankers Fast ferries and aluminium vessels Temporary and permanent installationsRapid response and emergencies

    Installation dimensions

    Pneumatic fenders must be installed onto a solid structure or reaction panel to ensure

    that they are properly supported during impacts.

    HYDRO-PNEUMATIC FENDERSSubmarines and other vessels which contact fenders below waterline require a unique solution. Hydro-pneumatic fenders are specially adapted to this application. The fender body is partially water-fi lled, then pressurised with air and ballasted to make it stand vertically. Fender draft and performance can be tuned by altering the water:air ratio and infl ation pressure.

    FeaturesSub-surface contact face Very low hull pressures Variable draft Prevents acoustic tile damage

    Due to the very specialist nature of Hydro-pneumatic fenders, it is strongly advised that a detailed study be carried out for each case.

    Please ask for assistance with this.

    Wheel fenders are widely used on exposed corners to help ships manoeuvre into berths and narrow channels such as locks and dry-dock entrances. The main axle slides on bearings and the wheel reacts against back rollers to provide high energy and minimal rolling resistance, whilst the stainless steel and composite Trelleborg Orkot bearings are almost zero maintenance.

    FeaturesHighest energy absorption Very low rolling resistance Use singly or in multiple stacks Composite and stainless steel bearingsLow maintenance casing design

Roller Fenders use stainless steel and composite Trelleborg Orkot bearings which give a very low rolling resistance and req
