Two approach channels, one N of Holmengraa and the other S of Fedje, with very deep water, give good access to Mongstad Harbour.
The approach to berth no. 4 in Mongstad Cove is via Leirvaagsundet between Haavarden Island and the mainland.
All jetties are operated on a 24 hour basis, seven days a week, thus permitting vessels to berth, load or discharge cargoes and unberth at any time.
It is of 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 ships above 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. When the light is red the vessel must not tighten the mooring lines. When the light is green the vessel is permitted to tighten the mooring lines.
The Master shall ensure that all moorings 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 link. Wire and rope must not be mixed in the same service. All vessels, while alongside at the jetty, must provide and rig emergency towing wires with 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 permantly installed on mooring winches, shall be fastened directly to the ship's bollards. All vessels must in addition to the normal number of mooring lines, have two spare lines forward and aft.
