Final offshore platform sets sail for Moray East offshore windfarm

The third and final Siemens Energy Offshore Transformer Module set sail left the fabrication yard last weekend on route to the Moray East offshore windfarm project, located 22km from the Aberdeenshire coast in Scotland, marking a significant milestone in the project’s development.

The 950-MW Moray East Project will use 100 100 V164 – 9.5-MW turbines and will generate power at a cost of £57.50/MWhr [about US $76.68 oer MWh], the lowest cost of any new renewable generation and two-thirds less than offshore windfarms in operation around the UK today (typically upward of £140/MWhr), according to Siemens.

An OTM is the substation platform out at sea and in a world’s first, three of these will be connected with the capacity to deliver the 950 MW clean energy from the Moray East project.

The OTMs, which were fabricated and fitted out in Hoboken, Belgium by Smulders, ENGIE Solutions and Siemens Energy, are an essential part of the wind farm because they stabilize and maximize the voltage of the power received from the offshore wind turbines before transmitting the electricity to shore.

The OTMs will sit on three-legged jackets and each weigh-in at around 1,100 tonnes. Each module will transmit the power generated by the 100 turbines across the 295km2 site, back to
