Validation of Dynamic Response of a 2-MW Hybrid-Spar Floating Wind Turbine During Power Production

Abstract

In this paper, we describe simulation of the dynamic response of a 2-MW spar type floating offshore wind turbine (FOWT) during power production in actual sea area. Accurate estimation of the dynamic response of FOWTs are essential for the design and development of FOWTs to ensure their safety and reliability. Therefore, this paper compares and validates the simulated and measured dynamic response of FOWTs during power production using Adams with SparDyn, which has already shown good agreement with measured values under a typhoon environment. Five simulation cases were selected from low to high wind speed range during power production. Numerical simulations were performed using time series data of wind speed, wind direction, wave height, wave direction, current speed and current direction obtained during power production. Comparisons have shown reasonably good agreement between the simulated and the measured values except yaw motion.
