The offshore array

The offshore array encompasses the wind farm site itself, and will include:

  • 90 x MHI Vestas’ v164-9.5 MW wind turbines
  • 90 x steel monopile foundations
  • 2 x offshore substations
  • ‘inter-array’ cables linking the wind turbines and the offshore substations
  • SOV mobile facility for operations and maintenance staff and equipment.

The offshore array Development Consent Order

The consent application for the offshore array was submitted to the Infrastructure Planning Commission, later replaced by the Planning Inspectorate (PINS) in August 2012, and included an Environmental Statement containing the results of the project’s Environmental Impact Assessment.

The Secretary of State granted a Development Consent Order (DCO) for the offshore array on 11 July 2013.

Review of the offshore array

Following detailed technical and commercial optimisation studies undertaken by Triton Knoll, together with the Crown Estate, in January 2014 it was decided to reduce the overall generating capacity of the scheme to a maximum of 900MW. This was considered to make better use of the site within the Triton Knoll offshore wind farm array’s consented boundary. Following further, more detailed site investigations the final maximum installed capacity of the offshore wind farm will be 857MW.
