Outline of Final Research Achievements |
In this study, we suggested a new type floating ocean WTGS(wind turbine generator system) to utilize a renewable energy positively against the background of Japan’s very large ocean, and carried out the feasibility study for the system. This system has a catamaran hull with one 600-kW-order wind turbine and a hydrofoil is installed under the bow of the hull. Then the hull motion or the forces on a mooring system could be significantly reduced using the wave energy. From the results of model tests, the effect of a hydrofoil on reducing the motion in waves is mainly based on the viscous damping forces. And it is confirmed that the effects on reducing the hull motion or the wave drift forces, not only with a hydrofoil but also with a flat plate.
