摘要：
Based on the potential flow theory, the frequency domain hydrodynamic numerical model of Windfloat semisubmersible floating offshore wind turbine(FOWT) platform was established by using BEM method. The effects of the structural parameters(column diameter, column spacing and draft, et al.) on the stability, added mass radiation damping and firet-order wave excitation force obtained of Windfloat semisubmersible FOWT were explored. The results show that the column diameter has a great influence on the stability, added mass, radiation damping and first-order wave excitation force of Windfloat semisubmersible platform. The change of platform draft has a large effect on the added mass, but the influence on radiation damping and first-order wave excitation force is small. The change of column spacing will not only affect the hydrodynamic coefficients, but also lead to the shift of the peak corresponding frequency of the hydrodynamic coefficients in the high frequency region. © 2022 Central South University of Technology.
