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 fitted with

a chain-tyre net (CTN) for added

protection. For navy ships, a grey

body is also available.

Features

Easy and fast to deploy

Very low reaction and hull pressure

Suitable for small and large tidal

ranges

Maintains large clearances between

hull and structure

Applications

Oil and gas tankers

Fast ferries and aluminium vessels

Temporary and permanent

installations

Rapid response and emergencies

HYDRO-

PNEUMATIC

FENDERS

Submarines 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-filled,

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 ination pressure.

Features

Sub-surface contact face

Very low hull pressures

Variable draft

Prevents acoustic tile damage

Applications

Some 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 absorption

Very low rolling resistance

Use singly or in multiple stacks

Composite and stainless steel

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.

Cushion Rollers are used to guide

pontoons and oating structures

quietly and gently up and down

their guide piles. The resilient

wheel can be supplemented by a

rubber cushion pad to withstand

berthing impacts. Stainless steel
