Fendering
Floating Fenders
A PT1/8 air valve is fitted at the end of the fender to allow access for
inflation whilst ensuring maximum protection from damage during
normal use.
Application
Vessels carry the fenders onboard with them at all times, for use both
at home, at sea and in foreign ports as utility fenders. The fenders are
used primarily for two applications – ship-to-quay and ship-to-ship. For
ship-to-quay application the fenders are used to berth a vessel alongside a
quay or wharf. For ship-to-ship application the fenders are used to berth or
moor two vessels side by side (double-banking) in port or at sea.
There are three main configurations for fender grouping when in use:
Mooring positions of the fender groups on the ship should keep the ship
separated and stable at the same distance from the quay or another ship
all along the parallel mid-body.
Berthing against a quay or a stable ship moored in port is straightforward
but the following should be considered when confirming fender size: (1) the
approaching ship’s docking speed, (2) approaching angle, (3) hull shape,
(4)
protrusion from ship and (5) equipment fitted on the hull.
It should be carefully noted that required stand-off distance is an important
variable to consider when berthing. For example, if a vessel is light in weight
but requires a stand-off of 2 metres (due to large flare or parts/equipment
standing proud of the hull such as a stabiliser) then larger fenders would
be required.
