Construction is underway off the northern coast of the U.K. for Ørsted’s planned 1.2-gigawatt wind farm, with 174 8-MW turbines expected to be planted and operational by 2021 in a field about 120 kilometers (75 miles) from shore. Ørsted, the Danish energy engineering company formerly known as DONG Energy, contracted for the GeoSea vessel Innovation to deliver the first of 174 monopiles to drive into the seabed for the wind power farm Hornsea Project One. The monopiles set the foundation for a turbine, which is then mounted on another tall stalk above the waterline. Innovation can carry four of the 65-meter-long monopiles, each of which weigh 800 tons and has a diameter of 8 m.
