Passage planning charts and associated waypoint lists for arrival and departure are attached for reference. The passages and waypoints described must be loaded onto the ship’s ECDIS displays in preparation for port entry. The pilot will refer to the intended courses and a member or members of the ship’s Bridge Team should be designated to monitor the progress of the vessel throughout the passage.
Gisborne is a ‘surge port‘. The surge is generated by long waves of low amplitude (Infra-gravity waves, or IG) which fluctuate more or less in synch with the tide cycle. Highest amplitudes tend to coincide with high water.
At times of low IG ship’s mooring lines will be used in a 4 & 2 configuration – 4 head/stern lines and 2 springs fore & aft.
At times of higher IG, ShoreTension (ST) equipment (www.shoretension.com) will be utilised.
With ShoreTension equipment the ship will make fast with ship’s lines in the following configuration:
- 2 back springs forward and aft. Springs must be fed directly from ship’s mooring winch drums.
- Either an eye and a bight, or 2 bights (depending on prevailing conditions – Pilot will advise) fed directly from off-side winch drums.
The ship will then receive a high breaking load (200t mbl) high modulus line from the shore side at each end of the ship. This line will enter through the centre lead fore and aft.
A mooring crew comprising 2 mooring-men will board the vessel via ship’s gangway once alongside and in position with both spring lines secured. The mooring-men will provide guidance to the ship’s crew on the focsle and the poop during the mooring process.
