Building a Floating Wind Farm Off the Fukushima Coast

  • The first stage of the Fukushima wind farm experiments involves construction of a floating electrical substation and a 4-column semisubmerged wind turbine. Stage two includes an advanced spar-buoy floating wind turbine and a 3-column semisubmerged turbine model. (Courtesy the Fukushima marine wind power consortium.)

  • Annual average wind speed off the coast of Fukushima, Ibaraki, and Chiba Prefectures. The average maritime wind speed at one location off the coast of Iwaki, Fukushima, measured over a two-year span was 7.4 meters per second, with monthly maximum wind speeds exceeding 9 m/s, compared to an average wind speed on land of just 4.3 m/s.
