Abstract

In recent years, the research and development of floating offshore wind turbines (FOWT) have accelerated to harvest energy more effectively by aiming for higher and more stable wind speeds. As the sites develop further offshore and into deeper water, the hydrodynamics parameter of the floater becomes increasingly important due to its significant impact on the wind turbine's performance. In this regard, the present papers discuss the phenomenon of response dynamics that changes in floater geometry affect the hydrodynamic performance of FOWT by utilizing the potential flow theory in BEM solver via the open-source software NEMOH. The OC3-Hywind spar-type floating platform was selected, and the geometric was varied to adapt to the depth of the site. Initially, the hydrodynamic analysis was conducted using a reference model, and the results were compared with the reference data. Based on the results, it is found that that pattern from the pioneer work and the current study has the differences 3-5%.
