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.
Features
Easy and fast to deployVery low reaction and hull pressureSuitable for small and large tidal rangesMaintains large clearances between hull and structure
Applications
Oil and gas tankersFast ferries and aluminium vesselsTemporary and permanent installationsRapid response and emergencies

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.
Features
Sub-surface contact faceVery low hull pressuresVariable draftPrevents acoustic tile damage
Applications
SubmarinesSome fast ferriesSemi-submersible oil rigs

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.
Features
Highest energy absorptionVery low rolling resistanceUse singly or in multiple stacksComposite and stainless steel bearingsLow maintenance casing design
Applications
Dry-dock entrances and wallsLock approachesExposed corners

Roller Fenders are usually installed to guide ships in restricted spaces like walls of dry docks. They can also be used on corners and lock entrances where lower energies are needed. Roller Fenders use stainless steel and composite Trelleborg Orkot® bearings which give a very low rolling resistance and require virtually zero maintenance.
