Numerical Estimation of Hydrostatic and Hydrodynamic Forces of Spar Type Offshore Wind Turbines

Abstract

Abstract The focal point revolves around Floating Offshore Wind Turbines (FOWT) due to fossil fuel leakage. Numerical simulation tools have been developed to simulate the operational dynamics of FOWT under different wave conditions.In this study,a numerical approach is proposed to investigate FOWT using ANSYS-AQWA a commercial soft wares uses potential theory that employs the boundary element method to obtain the added mass, radiation damping and diffraction in three translational degrees of freedom (surge,sway,heave).in this study considers. This paper compares two numerical approaches for studying offshore structures. The first approach was conducted using WAMIT, and in this work, a verification of the with the well known Spar offshore wind turbine OC3 will be introduced. The heave response of FOWT will be considered in regular waves. Response Amplitude Operator (RAO) is considered in Heave Motion. The simulation achieves high accuracy with minimal errors, and its processing time is significantly shorter compared to CFD simulations.
