Report No: 05NZ104 WELLINGTON HARBOUR Issue: Issue 1.1 Operational Risk Assessment 8 PILOTAGE 8.1 INTRODUCTION Although there are natural navigation hazards, the pilotage is relatively straightforward with weather, particularly at the entrance and outer boarding areas, providing the biggest limitation. However, if a vessel does get into difficulty in adverse conditions in the approaches, there is only a minimal margin of safety before a vessel is in serious danger of grounding. The length of transit under pilotage from the outer boarding areas to a main city berth is about 10 miles. 8.2 JURISDICTION AND REGULATORY RESPONSIBILITY The outer limit of the Wellington Pilotage District is marked on NZ4633 as an arc centred on Outer Rock of three miles radius and is therefore 0.85 miles inside Wellington Harbour Limits. Thus the Pilotage District is approximate only with the Regional Council Harbour Bylaw area of jurisdiction, pilotage being the jurisdiction of Maritime New Zealand. However, as introduced in section 4.1, the limit of compulsory pilotage is inside the entrance12 and the outer limit of pilotage jurisdiction in reality provides only guidance for boarding. This is taken further to a recommended solution in section 13.5. Figure 9, below, repeats the limits of pilotage jurisdiction and shows the four designated boarding areas, all outside the compulsory area. Nationally Pilotage is regulated under the provisions of the Maritime Transport Act 1994 through Maritime Rule Part 90. This Part came into force in 2003. Vessels of more than 500GT (with the normal exception of warships), are subject to Pilotage in the Compulsory Pilotage Limit of Wellington Harbour. 8.3 BOARDING AREAS Four Pilot Boarding Areas are designated within the Wellington Pilotage District and located both within and outside the harbour entrance (shown on Figure 9). Areas ‘Alpha’, Bravo’ and ‘Charlie’ are outer areas, located at the seaward extremity of the Pilotage Limit and approximately 3 miles south of the entrance. These are placed on and to either side of the line of the leads 12 The Compulsory Pilotage Limit for Wellington encompasses the harbour area north of a line between Point Gordon and through the Rear lead to the eastern shore, as marked on NZ4633. This also coincides with the boundary between risk assessment areas A and B. Greater Wellington Regional Council / CentrePort Ltd Page 51 of 102
Report No: 05NZ104 WELLINGTON HARBOUR Issue: Issue 1.1 Operational Risk Assessment (Alpha is on the line of the leads) 13. An inner boarding area, ‘Delta’, is located in the entrance channel approximately 0.5 mile south of the front Lead. 8.3.1 Outer Boarding Areas Figure 9: Pilotage Jurisdiction and Boarding Areas The outer boarding positions, Alpha’, Bravo’ and ‘Charlie’, are intended to suit vessels approaching from various directions rather than to suit prevailing weather conditions. However in adverse weather, where there is doubt as to whether a vessel will be boarded outside or led in to Delta, then the vessel is usually directed to wait on the line of the leads at least 3 miles off (ferry traffic is likely also to be joining the leads further out too). Then the inward run is commenced from Alpha. This makes navigating to an 13 They were promulgated after comment by the Court in the Formal Investigation of the grounding of PACIFIC CHARGER, where the Court found that precise positions for the pilot boarding should be given … and defined on charts.
