Chern Fong Lee has conducted research on the numerical modelling of Combined Wind and Wave Energy Systems for Intermediate Water Depths. On 30 October, he defended his doctoral thesis.
On Wednesday 30 October, Chern Fong Lee defended his doctorate at the University of Stavanger (UiS). The title of the thesis is "Design, Numerical Modelling and Dynamic Analysis of Combined Wind and Wave Energy Systems for Intermediate Water Depths". The main supervisor was Professor Muk Chen Ong (UiS).
In his research, Chern Fong has performed the dynamic analyses of two combined wind and wave energy systems, i.e., the Semi-submersible Torus Flap Combination (STFC) and the Two-rotor Semi-submersible Torus Combination (2WT-STC) for intermediate water depths. The interactions between the floating offshore wind turbines (FOWT) supporting platforms, the wave energy converters (WECs) and the mooring systems, are modelled with three objectives: (1) to estimate the power absorption potential based on the WECs’ motions, (2) to accurately incorporate the damping effect provided by the WECs into the overall system and (3) to propose appropriate mooring systems for intermediate water depths. These objectives serve as critical indicators for evaluating the synergy between the different components of the integrated wind and wave energy systems at intermediate water depths.
During the trial lecture, Chern Fong presented an overview of shared mooring systems between multiple floating offshore wind turbines by focussing on the fatigue of the moorings and structure dynamics of the floating structures. The engineering challenges and solutions of shared mooring systems were outlined.
Chern Fong Lee's work has been part of the Akademia-programme that UiS has with Equinor.
