If for any reason shore mooring gangs are not available to let the ship go then the mooring lines
shall
initially
be run as bights, with the line lead around the shore bollard and the eye then returned onboard, so they can
then be brought in without the need for ships personnel to remain on the shore during the unberthing
operation.

The correct operation of the mooring equipment onboard is essential to the overall safe operation of the ship
in port. All parts of the mooring system
shall
be incorporated into the ships planned maintenance system.
All rotating parts
shall
be moved and greased on a regular basis via grease nipples and the ways being kept
clean and in good condition. Particular attention
shall
be paid to roller fairleads and rotating deck stands as
these often suffer from neglect and little use. Rollers and fairleads
should
turn smoothly and a visual check
made that corrosion has not weakened them.
Surfaces of fairleads, bollards, bits and drum ends
shall
be kept clean and maintained in good condition.
Regular inspections
shall
be made of the winch brake linings. Oil, moisture or heavy rust on brake linings or
drums can seriously reduce the brake holding capacity, in extreme cases by as much as 75%.
Moisture can be removed by running the winch with the brake applied very lightly, although care
shall
be
taken not to cause excessive wear. When oil has impregnated into the brake lining, this cannot be removed
and any lining which has been affected
shall
be replaced at the earliest opportunity. The possible reduction
in any winch brake holding capacity
shall
be taken into account when deciding upon the mooring pattern to
be used.
Whenever brakes are opened up for any reason, the brake drum
shall
be examined for build-up of rust or
worn brake material and
shall
be de-scaled as necessary.
Brake linkages
shall
be free to move. If the linkages are not free then there
shall
be a loss in the brake
holding capacity. The operator may be under the impression that the brake has been fully applied when in
fact it has not or the brake mechanism is hardened up using lever bars which may in turn impose high
stresses on some of the mechanical parts of the brake.
Prior to a mooring operation which follows an extended sea passage or a passage undertaken in heavy
weather, the winches that have been exposed
shall
be checked to ensure that all control and operating
levers and linkages are oiled or greased and are free and easy to use and that the brake drums and linings
are clean and suitably dry.
The deck areas at mooring stations
shall
have anti-slip surfaces provided by fixed treads or by painting with
anti-slip paint.
Records
shall
be maintained of all inspections and maintenance carried out on the mooring system.
All mooring equipment
shall
be certified. This means that for mooring ropes at least a batch certificate
shall
be available on board the vessel.
All mooring equipment like bollards, fairlead rollers etc
shall
be marked with their SWL.
All mooring lines
shall
be marked in order to be identified using color collars (and associated to their relevant
certificates).
The mooring lines in use
shall
be visually controlled on monthly basis as per the PMS system requirements.
