UK: The last of three offshore substations for the Moray East offshore wind farm left the fabrication yard and sailed away to its offshore location in the UK North Sea over the weekend.
The substation, a Siemens Energy Offshore Transformer Module, fabricated and fitted out in Hoboken, Belgium by Smulders, ENGIE Solutions, and Siemens Energy, will join the two already installed “sister” units and be used to maximise the voltage of the power received from the offshore wind turbines before transmitting the electricity to shore.
The offshore substation will be installed on a three-legged jacket. Each of the three modules will transmit the power generated by the 100 turbines across the 295 km2 site, back to shore and into the national grid where it will be distributed to homes and businesses.
The 950 MW wind farm is being developed by Moray Offshore Windfarm East Ltd, which is a joint venture company owned by Diamond Green Limited (33.4 %), Ocean Winds (56.6 %) and CTG (10 %).
“The OTM, which is significantly smaller in size and weight compared to conventional alternating current offshore wind platforms, will transform the output voltage of the wind turbines from 66 kV to the transmission to shore voltage of 220 kV,“ said Siemens Energy, which designed the substations, adding that its OTM design uses a modular fabrication approach which saves cost and time in the delivery.
