INTERNATIONAL SAFETY GUIDE FOR OIL TANKERS AND TERMINALS

Severe loads can sometimes develop in mooring lines during the mooring
operation. It is essential that good quality moorings of adequate length

are used and that personnel are closely supervised so as to ensure their
safety.

At many conventional buoy mooring berths, the ship’s moorings are
supplemented by shore moorings run from the buoys or by ground
moorings. These wires are often heavy and the handling of them around
the warping drum of a winch should therefore only be undertaken by

experienced personnel.

Complicated and non-standard mooring arrangements at SPMs frequently
lead to dangerous and protracted operations. Therefore, the fitting, both
on ships and on SPMs, of well designed and, in the case of the ship,
accurately positioned, items of standard equipment will considerably
reduce the risk of injury to personnel. The proper fitting of such
equipment will also provide a more efficient method of securing ships to
SPMs at offshore terminals.

OCIMF has produced guidelines for SPM mooring equipment entitled
‘Recommendations for Equipment Employed in the Mooring of Ships at
Single Point Moorings’ and it is recommended that they are followed by all
ึ
SPM terminals and the ships using them.

A storage drum should be used to heave in the SPM pick-up rope prior to
connection of the chafing chain to the stopper. A warping end should
never be used for this purpose.

Ship and terminal operators should refer to the OCIMF publication ‘Single
Point Mooring Maintenance and Operations Guide’ for detailed
information regarding SPM operations.

23.5.3 Management of Moorings at Buoy Berths
While the tanker is at a conventional multi-buoy mooring, frequent and
regular inspection is essential to ensure that mooring lines are kept taut
and that movement of the tanker is kept to a minimum. Excessive
movement may cause rupture of the cargo connections.

At single point moorings, a watchman (equipped with appropriate means
to communicate with the Officer of the Watch) should be stationed on the
forecastle head to report any failure or imminent failure of moorings or
leakage of oil. The watchman should also report immediately if the tanker
‘rides-up’ to the buoy and should be equipped with appropriate means to
communicate with the Officer of the Watch.
