Watch the Evolution of the World's First Floating Wind FarmS. Himmelstein | October 19, 2017
The six 5 MW floating turbines comprising the 30 MW Hywind Scotland project have started delivering wind-generated energy to the grid.
The wind farm operated by Statoil and United Arab Emirates-based Masdar is sited 25 km offshore from Peterhead in Aberdeenshire, Scotland, and will provide power for approximately 20,000 households. Statoil assembled the turbines in Norway and ferried them about 1,000 miles south to be secured to the seabed by three 16 m (52 ft.) tall, 5 m (16 ft.) diameter suction anchors. Each anchor weighs 111 tons, ensuring that the turbines stand upright. These floating turbines are anchored at 78 m (255 ft.), and they can be rigged at depths of over 800 m (2,600 ft.). The wind farm also includes Batwind, a 1 MWh lithium battery storage solution for offshore wind energy.
“Statoil has an ambition to reduce the costs of energy from the Hywind floating wind farm to € 40-60 €/MWh by 2030. Knowing that up to 80 percent of the offshore wind resources are in deep waters (+60 m / 197 ft.) where traditional bottom fixed installations are not suitable, floating offshore wind is expected to play a significant role in the growth of offshore wind going forward,” says Irene Rummelhoff, executive vice president of the New Energy Solutions business area at Statoil.
