Embodiment Construction

[0029]In FIG. 1 the harbour ship is indicated with the reference numeral 1. The ship 1 comprises a seaworthy floating construction with two longitudinal floating bodies 2 connected at their front sides by a bow 3. The floating bodies 2 and the bow 3 delimit respective sides of a water basin 4 spared out within the outlines of the floating construction. The basin 4 has an entrance opening 5 at the back side of the ship 1. The basin 4 is provided with mooring positions 7 alongside which fenders 7a and davits 7b are provided. At these mooring positions 7 shuttle vessels 8, 9 are moored. The shuttle vessels 8, 9 are substantially smaller than the ship 1 and the basin 4 comprises more than enough space for each of them to sail into and out of the basin 4 without bumping against each other.

[0030]The ship 1 is firmly anchored to the bottom of the sea by means of anchoring means 10. The bow 3 is provided with sleeping quarters 11 for approximately 50 to 150 man, and workplaces and storage r...

Abstract

A method for use with maintenance of an offshore wind farm includes a plurality of offshore wind turbines installed in open sea, where the method uses an assembly of a plurality of shuttle vessels 8, 9 and a seaworthy harbour ship 1 which includes an internal harbour basin 4 within outlines of the ship 1 and a plurality of mooring positions 7 for mooring the plurality of shuttle vessels 8, 9 to the ship 1 when lying inside the basin 4, where the method further includes comprises sailing the assembly of the plurality of shuttle vessels 8, 9 and the harbour ship 1 towards an anchoring position near or in the wind farm and anchoring the harbour ship 1 there, and sailing the plurality of shuttle vessels 8, 9 back and forth between the mooring positions 7 of the anchored harbour ship 1 and distinctive ones of the wind turbines for performing the maintenance thereto.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is the National Stage of International Application No. PCT / NL2011 / 050052, filed Jan. 27, 2011, which claims the benefit of Netherlands Application No. 2004166, filed Jan. 28, 2010, the contents of which is incorporated by reference herein.FIELD OF THE INVENTION[0002]The invention relates to a method for use with the performance of maintenance to an offshore wind farm. The invention also relates to a harbour facility, in particular for use with such a method of performing maintenance to an offshore wind farm, and to an assembly of such a harbour facility and a plurality of shuttle vessels for transfer of service engineers from the harbour facility towards wind turbines of the farm and vice versa.BACKGROUND OF THE INVENTION[0003]An offshore wind farm usually comprises a cluster of some hundreds wind turbines. The large number is necessary to be able to efficiently transfer the generated electricity from the farm to the shor...
