Operations and Maintenance Base

The Seagreen Offshore Wind Farm will require an Operations and Maintenance (O&M) base for the duration of the 25 year operational phase. The base is a critical element of the wind farm and will be located at a port or harbour whose location is yet to be confirmed.

The O&M base will provide:

  • Warehousing for spares and equipment essential for maintaining Seagreen

  • Welfare facilities for the personnel running and maintaining Seagreen

  • Offices and meeting space

  • Location for the Marine Coordination Centre - which manages day to day vessel movements to and from site

The location of the O&M base will bring increased social benefit to the local area both in terms of employment opportunities but also in terms of the development of the O&M base itself.

For example, the Beatrice Offshore Windfarm chose Wick as the location for its O&M base and is currently restoring two 200 year old Thomas Telford buildings to use as their base as part of a c£20m spend at Wick Harbour.

Substation

Seagreen will build a new substation at Tealing which will receive the electricity generated by the wind farm for conversion up to 400kV for onward transmission on the national electricity transmission system.

The construction of the substation will lead to numerous opportunities not only in the actual construction which will take around two years to complete but also in the fabrication of the component parts.

In addition, local people and businesses will benefit from opportunities such as the provision of plant and materials and other services such as accommodation and food for the site operatives.

Onshore cabling

The electricity generated by the Seagreen turbines will be transmitted via subsea export cables to a landfall at Carnoustie.  Once ashore, the electricity is then transmitted from Carnoustie to our new Tealing substation via underground cables for a distance of approximately 19km.

The installation of the underground cables is undertaken by various specialised machines including directional drilling equipment where the cables need to pass road, rail or other sensitive areas.

The use of this technology enables the installation of the cables with the minimum of disruption.

Once the cables have been installed, the cable route will be carefully reinstated.

 

The installation of the cable will also provide significant employment and business opportunities for the up to two year installation period.
