UK subcontractor VolkerInfra will supply onshore cables and associated infrastructure for EDPR’s 950MW Moray East offshore wind farm off the coast of Scotland.
Contractor Siemens selected VolkerInfra, following a two-year competitive tender.
VolkerInfra will design, supply and install the onshore cables for Moray East, including the extra high voltage equipment for the offshore transmission modules.
The Preston-based company has completed cable route development works, including geotechnical surveys to finalise the route and the development of key design features to support applications for local and statutory authority planning consent permissions.
The Moray Offshore Windfarm (East) Limited consortium developing the offshore wind project off Scotland’s east coast is comprised of EDPR (43.3%), Diamond Green Limited (33.4%) and Engie (23.3%).
The initial design work commenced in late 2017 and the main pre-construction works started in October 2018.
The installation is planned to take two years to complete and will see VolkerInfra working with cables at voltages of 400 kilovolts (kV), 220kV and 33kV.
The works also include three 220kV circuits and multiple 66kV connections for three offshore transformer modules, the offshore equivalent of a land based electricity substation.
VolkerInfra will also install, connect and pre-commission test approximately 330,000m of 220kV onshore underground export cables, covering a route length of over 34km, as well as connecting two 400kV circuits between new and existing substations.
TFKable’s factory in Bydgoszcz, Poland, will produce the 220kV onshore high voltage cables. Production will start during the first quarter of 2019.
