About Westermost Rough

 The Westermost Rough Offshore Wind Farm is one of the Round 2 projects and is a joint venture between DONG Energy (50%) and its partners Marubeni Corporation (25%) and the UK Green Investment Bank (25%).

The offshore wind farm is situated 8km off the Yorkshire Coast, north of Hull and contains 35 turbines of 6MW capacity, covering a total area of 35km2 and providing enough electricity to power around 180,000 UK homes.




The Project marks the first commercial deployment of the Siemens 6MW turbine with a 154m rotor span. The 35 turbines are 177m tall from sea level to the highest reach of the blade tips, which is taller than the Humber Bridge.



It is estimated that the Westermost Offshore Wind Farm will be able to provide 210MW of electricity, which is enough to fulfil the requirements of approximately 180,000 British households. The Westermost Rough Offshore Wind Farm makes a significant contribution to the UK government renewable energy goals.

The offshore wind farm will also result in an annual reduction of approximately 264,429 tonnes of CO2, which would otherwise be produced by a power station using fossil fuels. This reduction significantly helps to fulfil the UK's commitment to reducing CO2 emissions.

​Operations and Maintenance

Westermost Rough operations and maintenance base 

Following commercial completion of Westermost Rough in September 2015, the operations and maintenance team are based out of facilities at the Royal Dock in Grimsby where they will manage the upkeep of the project for its 25 year lifetime.

Construction of the new offices and warehouse began in January 2014 and was completed at the end of the same year. Around 100 employees are based at the Grimsby site offices, which also has new pontoon access for 3 crew transfer vessels.
