>” The turbine has been built to withstand 65-foot waves.
The 344-foot 7 MW (megawatt) Offshore Hydraulic Drive Turbine features a rotor diameter of 538 feet and three giant blades, each stretching 262 feet in length. The structure is fastened to the seabed by four 20-ton anchors, and loose chains connect the turbine to the seabed, fortifying it against large waves.
One of the chief engineers of the turbine, Katsunobu Shimizu, told NBC News that “These turbines and anchors are designed to withstand 65-foot waves.” He also explained that “here we can get 32-foot-tall tsunamis. That’s why the chains are deliberately slackened.”
The consortium purposely designed the structures to be able to withstand the fierce and unforgiving weather native to Japan’s waters. In fact, this problematic weather even caused issues during the construction of the turbine. Installations had to be reportedly put on hold on four separate occasions because of typhoons.
The offshore wind turbine is one of three planed for the area.
The Fukushima Offshore Wind Consortium is led by Marubeni Corporation and also involves nine other firms, such as Mitsubishi Heavy Industries, which was the company that supplied the turbine. The $401 million project is funded by Japan’s Ministry of Economy, and was created for the purpose of developing and testing the wind technology for additional commercialization, and to bring new industry to the Fukushima region of Japan that was devastated by the earthquake in 2011.
The 7 MW offshore wind turbine is one of three turbines planned for the facility. When the final turbine is installed later this year, the three turbines are expected to generate a combined total of 14 MW. […]”<
