The experimental offshore wind energy project to be located outside of Fukushima that was started all the way back in early 2012 has been coming along, according to recent reports.
Sponsored by the Japanese Ministry of Economy, Trade, and Industry — with help from a consortium featuring Marubeni (project integrator), the University of Tokyo (technical advisor), Mitsubishi, Mitsubishi Heavy Industries, Japan Marine United, Mitsui Engineering & Shipbuilding, Nippon Steel & Sumitomo Metal, Hitachi, Furukawa Electric, Shimizu, and Mizuho Information & Research — the beginning of the demonstration portion of the project is currently expected to in mid-December.
Most recently, the assembly work on a 7 megawatt (MW) oil pressure drive-type wind turbine (on a 3-column semi-sub floater) was completed at Onahama port. Delivery of the floater to the testing area — followed by the assembly + setting of a 7 MW oil pressure drive-type and a 5 MW downwind-type floating wind turbines — is expected to occur next.
Following the completion of those steps, the floater will then be delivered to the testing area and connected to external facilities via undersea cables. Once completed, data acquisition and analysis of operations will follow.
Marine Technology News provides more information:
Work progress to date on the 7 MW oil pressure drive-type floating wind turbine has included preceding works such as installation of chains, anchors and undersea cables at the testing area, delivery of the three-column semi-sub floater from Nagasaki to Onahama port, and installation of 7 MW oil pressure drive-type floating wind turbine on the floater.
As for the 5 MW downwind-type floating wind turbine, procurement of chains and anchors, and production of high-voltage riser cable have been successfully completed. Parts procurement and construction of 5 MW downwind-type floating wind turbine is in progress.
Commissioning of the project is currently expected to take place in mid-September.
