It is of the utmost importance for safe operations that ships are securely moored in the correct position at all times. The Master shall ensure that the vessel's moorings are closely monitored and tended regularly to prevent undue movements of the vessel. For vessels over 50,000 DWT a certain number of mooring lines permanently installed on mooring winches will be required.

Jetties 1, 7 and 14 have signal lights at the mooring points except for spring lines.


The Master shall ensure that all mooring on self-tensioning winches are secured with winch brakes in locked position. All use of self-tensioning winches in automatic position is strictly forbidden.


All mooring wires shall have rope tails connected with proper mooring links. Wire and rope must not be mixed in the same service. All vessels, while alongside the jetty, must provide and rig emergency towing wires of sufficient length and strength. These are to be placed on seaward bow and quarter. Wire eyes shall be suspended just above the water level, ready for emergency towing. Wires/ropes not permanently installed on mooring winches, shall be fastened directly to the ship's bollards.
