Investigation on Hydrodynamic Performance of Heave Plates under Semi-Submersible Floating Wind Turbines

Lookup NU author(s): Dr Arun DevORCiD



This article presents the effects of heave plate diameter and thickness on hydrodynamic coefficients and responses. In order to reduce heaving responses in offshore structures, heave plates are commonly used and a model which will display the effects of heave plates without the interference of other supporting braces and structures was used in this research with structural properties neglected. MOSES, a potential flow theory software, from Bentley Systems, was used to estimate the added mass and damping coefficients as well as the hydrodynamic response in the time domain.However, as viscous effects are neglected, the cases were simulated in Autodesk CFD, where viscous forces can be considered as a factor, and compared against published results. From this study, it was found that the Keulegan-Carpenter (KC) number has to be taken into ac-count when deciding the thickness of plates and wave amplitude was one of the key deciding factors for determining the heave plate diameter. It was expected that the data would contribute to determining the basic dimensions for circular heave plates under semi-submersible offshore floating wind turbines.
