Abstract
In order to utilize the huge amount of offshore wind energy located in relatively deep water areas, Ministry of the Environment, Japan funded on the demonstration project on floating offshore wind turbine (FOWT). In the project, two FOWTs have been installed. The first FOWT mounted a 100 kW wind turbine of downwind type, and the length dimensions are almost half of the second FOWT. The second FOWT mounted a 2 MW wind turbine of downwind type, and called as the full scale model. The FOWTs consist of PC-steel hybrid spar and are moored by three mooring chains. The half scale model was attacked by very severe typhoon Sanba (1216); the behavior of the half-scale model during the typhoon attack was recorded, and compared with the computer simulation, indicating the validity of the design method. After successful demonstration test of the half-scale model, the full-scale model was designed, constructed and installed at the same site. The demonstration test for the full-scale model has also been made successfully. After completion of the demonstration project, the full-scale model was moved to a different site off Fukue island, where it is operating as a commercial floating wind turbine.
