MOORING

This Chapter deals with the preparations and procedures necessary to provide
and maintain an efficient mooring arrangement whilst the ship is berthed at a jetty
or buoy mooring. Exchange of information between the tanker and the terminal
on matters relating to mooring arrangements is dealt with in Chapter 22.

The use of mooring equipment is described in detail in the OCIMF publication
‘Mooring Equipment Guidelines’. Descriptions of good operational practice for
mooring operations are given in the OCIMF publication ‘Effective Mooring’. Ship,
terminal and berth operators are strongly recommended to bring this information
to the attention of their respective workforces to ensure that the mooring operation
can be undertaken safely.

Mooring and unmooring operations, including tug line handling, are dangerous
operations. It is important that everybody concerned is fully aware of the
hazards and takes appropriate precautions to prevent accidents.

23.2 Security of Moorings

Any excessive movement or the breaking adrift of a tanker from the berth owing to
inadequate moorings could cause injury to personnel and damage to the jetty

Mooring restraint requirements for tankers above 16,000 tonnes deadweight intended
for general worldwide trade are given in the OCIMF publication ‘Mooring Equipment
Guidelines’. Those requirements are based on standard environmental criteria and
cannot possibly cater for the most extreme combination of environmental conditions
at every terminal. At exposed terminals, or those where for some reason the criteria
are likely to be exceeded, the ship’s moorings should be supplemented with
appropriate shore based equipment.

For ships below 16,000 tonnes deadweight and ships operating exclusively on a
dedicated route using terminals whose specific environmental data is available, the
recommended criteria may be revised to suit local conditions or trading patterns.

Although responsibility for the adequate mooring of a tanker rests with the Master,
the terminal has an interest in ensuring that ships are securely and safely moored.
Cargo hoses or arms should not be connected until both the Terminal Representative
and the Master are satisfied that the ship is safely moored.
