The development of the world’s first commercial scale floating wind farm, in which the UAE's Masdar has a 25 percent stake, has hit a major construction milestone.

All five turbines at the wind farm, which on completion will be sited off the coast of Aberdeenshire, Scotland, have been mated onto a floating substructure in Stord, Norway, ready to be towed into position 25km out to sea from the Scottish town of Peterhead and then anchored to the seabed.

The Hywind Scotland wind farm, a £210 million project unveiled in late 2015, is a partnership between the international energy company Statoil and Abu Dhabi’s renewable energy company Masdar.

Masdar’s acquisition of a 25 percent stake in the project was announced during Abu Dhabi Sustainability Week in January, with lead operator Statoil owning 75 percent.

The 30MW wind farm will occupy four sq km of space in an area of the North Sea which records average wind speeds of 10 metres per second. Upon completion in the fourth quarter of 2017, the project will provide around 22,000 UK homes with renewable electricity.

“We are excited to see the world’s first commercial scale floating offshore wind farm move a step closer to completion, demonstrating our long-term commitment to advance the commercialisation of renewable energy technologies,” said Mohamed Jameel Al Ramahi, CEO of Masdar.

“The deployment of commercially viable wind energy in deep water marks a new era of growth for wind power, allowing countries to further diversify their energy mix. We are proud to extend Masdar’s renewable energy portfolio in the United Kingdom and to build on our close partnership with Statoil.”

Hywind Scotland is the second offshore wind partnership between Masdar and Statoil after the 402MW Dudgeon wind farm, also due to come on-stream by the second half of 2017.

Installing, or “mating”, the five Hywind wind turbines onto their floating platforms is a major feat of engineering, with each turbine tower weighing 12,000 tonnes. The diameter of the rotor blades is 154 metres, nearly twice the wingspan of an Airbus A380, while the turbines themselves stand 253 metres tall (with 78 metres below the water surface). That is nearly three-quarters the height of the Eiffel Tower.

The immense structures are also built to withstand ocean waves at least 20 metres high and wind speeds exceeding 40 metres per second.

Hywind Scotland is set to be in full production by the end of 2017.
