When, eventually after consultation with the
P
ilot
or
Moorin
g
Master
, final details of the mooring operation
are known, the
Master
shall
instruct the officers or other responsible persons who are to supervise the
mooring operation fore and aft, on details of the mooring arrangements.
The instructions
shall
include:
x
The use of any tugs, their position and means of making fast;
x
The mooring layout to be used;
x
Sequence of running lines;
x
Safety precautions to be observed during the operation;
x
Position and method of rigging gangway or other access.
The mooring layout
shall
make best use of the mooring lines available. When the ship is fitted with wire and
synthetic rope moorings then it is often best to use the wires for springs and polypropylene breast lines and
the synthetic lines for headlines and stern lines. Whenever possible lines leading in the same direction
shall
be the same length and be made of the same material and construction. Mixed moorings, wire with synthetic
or wire or synthetic rope alone but with differing construction
shall
NOT be used in the same service.
The lead of the line to the shore
shall
also be considered. Whenever a line is unable to act in exactly the
same direction as the force it is trying to withstand, its holding power is reduced. The effectiveness of any
line is proportional to the cosine of the angle the line makes with the keyside. A line at twenty degrees
shall
be 94% effective, while a line at an angle of fifty degrees
shall
only be 64% effective.
Use
shall
be made of any berth information available from previous calls at the same berth.

The
Master
is responsible for ensuring that sufficient personnel are assigned to each mooring station.
When mooring stations are called by the
Master
, the Officer or other person in charge of each station
shall
brief the mooring party as to the safety and mooring requirements. Each person
shall
be checked to ensure
correct wearing of personal safety equipment such as suitable clothing, safety shoes, gloves, safety hat etc.
The ford mooring party
shall
also be provided with goggles in the event the anchor has to be used during the
mooring operation - planned or unplanned.
The mooring stations
shall
be prepared and ready for use prior to arrival of the ship at the berth.
Communication links with the bridge
shall
be tested. Lines run out
shall
be clear of the main working areas
