Moray West, an offshore wind farm in the outer Moray Firth, has selected the Siemens Energy/Iemants consortium to supply the project’s two offshore substation platforms using Siemens Energy’s Offshore Transformer Module (OTM) technology. The contract is subject to the award of a Contract for Difference in 2022 and Financial Close.  

Iemants is a subsidiary of Smulders, alongside Smulders Projects UK, based in Wallsend, Newcastle. The Siemens Energy/Iemants consortium will bring assembly and fit out of the OTMs to the Smulders Projects Wallsend yard. The yard fabricated jacket foundations for the neighbouring Moray East project, and this will see the scope of work extended.

Project Director for Moray West Adam Morrison said: “Siemens Energy brings a strong track record and we have worked well together on delivery of the Moray East OTMs.  Moray West will utilise the next iteration of the Siemens Energy Offshore Transformer Module concept which will ensure the project can reliably export excellent value green electricity to consumers across the UK.

“We are particularly delighted to secure topside work in the UK again, an important win for the UK Government’s Green Recovery. We look forward to working with the joint venture to maximising further local UK content.”


Phil Manley, Project Director for Siemens Energy UK&I, said: “This project will be an important step forward in reaching the UK Government target of increasing offshore wind power to 40GW in the next decade. Ensuring the UK supply chain can benefit from these important projects is something we are incredibly proud of, and we’re delighted to bring further content back to the UK with our partners.”

Tom Coosemans, General Manager of Smulders Projects UK, commented: “Local or UK-content sits high on the agenda and together with our strategic partners, we strive to increase local content going forward in this very competitive international market.

“The Moray West project allows us to kickstart further projects at the Smulders’ yard in the North East, building the path for supplementary green jobs and securing additional local content projects in the near future”.


Moray West has planning consent and grid connection, and awaits the award of a Contract for Difference (CfD) for which it is preparing to compete at the next auction, set by the UK Government, to allow the project to proceed to construction. The project is expected to be fully operational by 2024, with a lifespan of 25 years. It will consist of up to 85 wind turbines, two offshore substation platforms and offshore 65 km export cables.

It is being developed by Moray Offshore Windfarm (West) Limited, owned by Ocean Winds (95% stake) and Ignitis Grupe (5% stake). It is expected to enter the next CfD auction, which the UK government has confirmed will be run in 2022.


The development of Moray West follows on from the delivery of the adjacent
Moray East offshore wind farm, which features 100 MHI Vestas V164-9.5 MW turbines and three offshore substations. The 950 MW project is being developed by Moray Offshore Windfarm East Ltd and secured a Contract for Difference of £57.50/MWh from the UK government in 2017 and is due to start generating power in 2021. All turbines are in place at the project is expected to be fully operational in 2022.
