Study on the Influence of Heave Plates on the Hydrodynamic Characteristics of Offshore Semi-submersible Platforms
As offshore wind power advances towards deeper and farther seas,floating wind turbines have garnered widespread attention due to their significant cost advantages.The floating platform is the main supporting component of floating wind turbines.Under the influence of waves,floating platforms usually exhibit large motion responses,which severely affect the aerodynamic performance of wind turbines.Adding heave plates is a common control method for floating platforms,which can effectively reduce the large motions of floating wind turbines.This work studies the influence of heave plates on the hydrodynamic characteristics of a semi-submersible platform,using a self-designed column-stabilized semi-submersible platform as the research object and employing potential flow theory based on the Boundary Element Method(BEM).The research findings indicate that heave plates mainly affect the added mass in heave and pitch.Through a normalization analysis of the added mass in heave and pitch,it is observed that the correlation decreases with frequency.The mean value of the normalized results can be used to represent the added mass corresponding to different heave plate radii.This result can provide a preliminary assessment of the added mass for semi-submersible platforms with additional heave plates.
