This research project focuses on the investigation of hydrodynamic damping of a moored semi-submersible floating wind turbine using Reynolds-Averaged Navier-Stokes equations. The investigations include systematic verification studies comparing discretisation error and uncertainty quantification methods on different aspects of floating wind turbine simulations. The aspects are wave propagation, wave loads on a circular surface piercing cylinder, surge decay of a semi-submersible, and the dynamic mooring model in surge decay motion.
The discretisation error and uncertainty estimation methods rely on Richardson extrapolation. Furthermore, a variety of different settings and models are studied to predict hydrodynamic damping, including temporal and spatial discretisation, wave radiation, turbulence, and mooring models. For each model and setting, the hydrodynamic damping as well as the flow field are analysed. The extensive verification studies conducted in this project and the detailed investigation on hydrodynamic damping are new to the existing research on wind turbine floaters.
