Structural Parametric Optimization of the VolturnUS-S Semi-Submersible Foundation for a 15 MW Floating Offshore Wind Turbine

The full exploitation of offshore wind resources can essentially satisfy the massive energy demand. realization and application ultra-high-power turbines are crucial to achieving use deep-sea reducing cost power. For VolturnUS-S semi-submersible floating foundation a 15 megawatt (MW) turbine, effect structural parameters on hydrodynamic performance was investigated by controlling variables described in this paper. Accordingly, optimized coupled MW turbine. dynamic integrated turbine analyzed under different operating conditions, applying aero-hydro-servo-elastic method. results show that for wave 0-degree direction, 5% increase column spacing will reduce peak value pitch transfer function 33.61%, decrease outer diameter further 26.27%. standard deviation time-domain surge responses reduced 19.78% maximum mooring line tension 13.55% normal conditions.
