Viscous Damping for Offshore Floating Wind Turbine
Confirmation seminar presented by Chuansheng Wang
Floating platform is a major source of high cost, impeding the large-scale commercialisation of floating offshore wind turbines (FOWTs). Floating platforms mainly include barge, semi-submersible, spar and tension-leg platform concepts. Semi-submersibles predominantly adopt three- or four-column configurations. However, it is unclear what is the best column number from hydrodynamic and economic perspective. This research will optimise column configurations to reduce cost. When estimating the performance of floating wind turbines, there is no existing guideline on how to best determine the contributions of viscous damping. This project investigates the mechanism of viscous damping for semi-sub type of floating wind turbines, and develop a framework to accurately account for the viscous damping effects on global responses. To achieve this, experimental testing and computational fluid dynamics (CFD) modelling will be conducted.
About Confirmation Seminars
The purpose of the confirmation milestone is to ensure that the candidate receives appropriate feedback in relation to the viability and progress of the thesis project and that the resources required to complete the program of research within the recommended timeframe are available. It is also an opportunity to ensure that the candidate has demonstrated the capacity and capability to successfully complete the thesis in a timely manner.
