what is FENDER
A fender is a bumper used to absorb the kinetic energy of a boat or vessel berthing against a jetty, quay wall or other vessel. Fenders are used to prevent damage to boats, vessels and berthing structures. Fenders are typically manufactured out of rubber, foam elastomer or plastic. Rubber fenders are either extruded or made in a mold.
The type of fender that is most suitable for an application depends on many variables, including dimensions and displacement of the vessel, maximum allowable stand-off, berthing structure, tidal variations and other berth-specific conditions. The size of the fender unit is based on the berthing energy of the vessel which is related to the square of the berthing velocity. Marine fenders are used at ports and docks on quay walls and other berthing structures. The absorb the
kinetic energy of a berthing vessel and thus prevent damage to the vessel or the berthing structure. For bunkering operations between two vessels, floating fenders such as pneumatic or foam elastomer fenders are typically used.
Boat fenders are used on recreational boats, tugboats, ferries, naval vessels, passenger vessels, luxury yachts etc. boat fenders are also available in different types, such as ‘D’ fender, square fenders, wing fenders, keyhole fenders, etc..
