In recent years, development and research projects of the technology of wind energy are advanced positively. However, there is little examination about wind power energy on the ocean, and the investigation is insufficient. Then, in this study, the authors discuss developing wind power energy on the ocean. The possibility of developing wind power on the ocean, as one concept, an energy conversion system (called "the Wind Power Generation Fleet"), is investigated, and development research toward the practical use is also conducted. To be more precise, a degree of accuracy of the wind climate prediction in offshore windmill installations site is checked using the linear prediction simulator WAsP (The Wind Atlas Analysis and Application Program). A series of numerical simulation for wind power predictions have been conducted in four areas of Kanto Pacific Ocean shore/south islands. Consequently, even if WAsP compared with the nonlinear simulator, having equal prediction accuracy is shown. Moreover, it is shown that the wind power generation predictive accuracy is affected by the locational conditions of AMEDAS observation point. It is considered to lead to improvement in the prediction accuracy of WAsP to evaluate appropriately the influence of separate vortex flow in precipitous terrain of Japan.
