This paper describes the characteristics of wind loads on the bottom-mounted 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). 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 along-wind gust effect factors in the feathering condition for the wind of the seaside were from 1.8 to 2.0. Furthermore, the along-wind gust effect factors for the wind of the landside were from 2.1 to 3.5 in range of less than 30m/s.
