Bagbanci, H., Karmakar, D. e Guedes Soares, C. (2011), “Dynamic analysis of spar type floating offshore wind turbine”, Coastal and Maritime Mediterranean Conference, 22-24 Novembro, Tânger, Marrocos
In the present study, a coupled dynamic analysis of NREL 5MW Spar-type floating wind turbine is presented. The turbine design variables used in the analysis are the hub height of 90 m above the mean sea level, rotor diameter of 126 m and maximum rotor speed of 12.1 rpm. Hydrodynamic added mass, damping and exiting force are obtained in frequency domain using WAMIT and are validated with the result obtained for OC3 Hywind. The hydrodynamic study of the floater is combined with the FAST code to obtain a coupled aero-servo-hydro-elastic model. The spar-type floating wind turbine is considered to be connected with delta connection three mooring lines, and the mooring lines are fixed at bottom. The tower base motions and platform motions are obtained for wind speed 3.7 m/s with 4m wave height and 0º wave heading angle.
