This research and development project aims to develop a safe, reliable and economical floating offshore wind turbine system, making full use of deep water areas surrounding Japan. The targets are set as follows:
- Establish design methodology for a floating offshore wind turbine system in view of sever environmental conditions, such as typhoon, earthquake and tsunami
- Develop operation and maintenance methodology by using wind and wave forecast data
- Develop a coupled analysis model of wind turbine, floater and mooring
- Conduct economical evaluation of an offshore wind energy system, factoring in its uncertainty

The Japanese design method for wind turbines, which can withstand earthquakes and typhoons, contributes to energy infrastructure export. In addition, research and development activity of edged wind energy technology helps promote the development of human resources.
