Vessels will berth starboard side alongside. From the turning circle the LNG ship will move, in reverse, with the bow into the predominantly SW-ly wind into a position parallel to the jetty, maximum 75 meters away and with the vessel stopped in the water. The tugs will pull the LNG ship backwards and the ships rudder and engines will be used to control the astern speed and to maintain the ideal heading of 225 degrees. The tugs will then push the vessel onto the breasting dolphins. To avoid damage to the jetty fenders the vessel should be landed squarely on the fenders with a contact speed not exceeding 16 cm/second. The LNG Jetty is equipped with a speed of approach device.
Only after the vessel has been positioned and is being held alongside the berth by the tugs, should mooring lines be passed to shore. The sequence of mooring (where applicable) is as follows:-
All heaving lines for the forward and aft moorings should be passed to breasting dolphins BD1 and BD4 where they will be attached to the messengers by the shore mooring gang. The messenger can then be hauled on board the vessel and secured to the appropriate mooring line.
Attempting to secure more than one mooring line on a single messenger is unsafe and will only extend the time taken to complete the mooring operation. In the interests of safety and until all mooring lines have been passed to a particular dolphin, it is extremely important that the ship’s crew do not heave on any mooring lines until the Loading Supervisor has confirmed by radio to the pilot that all shore personnel are clear of the mooring dolphin concerned.
When unmooring under normal circumstances mooring lines will be released and recovered by the ship starting with outer mooring dolphins, forward and aft (MD1 & MD6), with back-springs being the final lines to be released. Mooring lines to be released must be slacked down into the water before the shore mooring crew will release the hook. Once the line has been released the pilot will be informed by radio and will confirm with the ship’s Master that it is safe to recover the mooring line. On no account should the ship’s crew heave on mooring lines until they are advised to do so by the Pilot.
The cargo throughput capacity of the LNG berth is 11,000 m3/hr.
