    Dynamic analysis of different configurations of offshore floating wind turbine
    (2018) Daranikota, A.; Karmakar, D.
    The dynamic response of different types of spar and semi-submersible type floating offshore wind turbines are investigated subjected to wave and wind loads in operational conditions. The study is performed for the NREL 5MW wind turbine supported on spar and semi-submersible platforms. The study includes the analysis on the wave interaction with supporting structure and determination of the time-domain dynamic response of offshore floating wind turbine. The hydrodynamic coefficients added mass, damping, excitation forces and Response Amplitude Operators (RAOs) of the different motions of the floating platform are analyzed for different wave heading angles. The coupled dynamic analysis is performed for both regular and irregular waves and the coupled response of platform motions, tower base forces and moments for different wave and wind load conditions is analysed. The present study focuses on the overall performance of the different types of spar and semi-submersible type offshore floating wind turbines. � 2018 World Scientific Publishing Co. Pte. Ltd.
