Having a long coastline, offshore wind energy is one of the most important solutions for the increase of renewable energy in Japan. However, due to the differences in wind, marine and earthquake conditions between Japan and Europe, the safety, the environmental impact and the economic feasibility of offshore wind energy have to be investigated. Since 2009, the authors have started an experimental investigation of NEDO's offshore wind power generation system proving research project on the Pacific Ocean near coast of Japan. This project aims to establish an offshore wind power generation technology which is suitable for Japanese external conditions. This paper describes the characteristics of wind loads on the offshore wind turbine tower. The site is located at 3.1km offshore from Choshi, and the water depth is 11.9m. Proving wind turbine is a propeller-type with three blades (Hub height: 80m, Rated power: 2.4MW, Bottom-mounted). The wind loads were investigated as bending moment at bottom of tower by using strain-gauge data. In this paper, obtained wind loads were compared between operational condition and feathering condition, wind of the landside and of the seaside. As a result, in both condition, the maximum wind loads for the wind of the landside were bigger than those for the wind of the seaside under the influence of the land 3.1 kilometers away from the wind turbine. The gust effect factors in the feathering condition for the wind of the seaside were from 1.8 to 2.0. Furthermore, the gust effect factors for the wind of the landside were more than 2.1 in range of less than 30m/s. |
