VolkerInfra, a specialist Extra High Voltage cable systems solutions provider, has been appointed by Siemens to design, supply and install the onshore cables for the Moray East Wind Farm project, including the EHV infrastructure for the offshore transmission modules, in Scotland.
The contract award follows a two-year competitive tender process, which saw VolkerInfra’s specialist in-house work winning, and design and engineering teams working closely with main contractor, Siemens.
VolkerInfra has completed cable route development works, which included 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 is currently owned by EDPR (43.3%), Diamond Green Limited, which is partly owned by DGE (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 400kV, 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. In addition, VolkerInfra will 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.
Peter Cooke, technical development director at VolkerInfra, said: “We are delighted to have been selected as the supplier of choice for this highly competitive Moray East offshore wind project. Our team, led by Kevin Grey, is now busy carrying out preconstruction activities on site and we are looking forward to supporting the project throughout the various construction stages, and delivering a first class project, on-time and safely, to meet and exceed all our expectations.”
The project is located off the east coast of Scotland and is expected to produce enough power for 950,000 UK homes.
