FLOATING OFFSHORE WIND TURBINE DEMONSTRATION PROJECT

For the promotion of the reduction of domestic greenhouse effect gas discharge in the middle and long term period, introduction of renewable energy is strongly encouraged.
Japan is one of seafaring nations which has sixth widest exclusive economic zone in the world.
The result of the investigation regarding the introduction potentiality of renewable energy is showing that Japan has large potentiality of wind turbine not only onshore but also offshore.
Since the speed of wind is faster and less inconstant offshore, stable and efficient power generation is expected and commercial use of wind turbine offshore is hoped.
Implanted method system of offshore wind turbine which is suitable for the shallow area has been under operation at three sites in Japan and substantiation studies of the wind condition observation system and wind turbine system are carried out by the Ministry of Economy, Trade and Industry.
With regard to the Floating method system which is corresponding to the deeper area, there is only one 2.3MWcommercial plant under operation in Norway and no yet introduction case in Japan.
Therefore, Ministry of the Environment has launched the demonstration project aiming for the installation of one 2MW class Floating offshore wind turbine test plant in the water as the first case in Japan from fiscal year 2010.
Through the project, selection of the candidate site (vicinity of Kaba Island, Goto City, Nagasaki Prefecture), drawing up of the proposal for the Method Statements of Environmental Impact Assessment and Crisis Management Manual, and manufacturing of small-scale test plant with 100KW windmill have been carried out.
Investigation, projection and evaluation of the impact for the meteorology, marine phenomenon and
environment during installation or operation of the small-scale test plant and placing , operation and maintenance of the small-scale test plant are under execution in fiscal year 2012.
Also, building of the full scale of demonstration plant with 2MW windmill which is scheduled to be placed in fiscal year 2012 is going.
