Wake Interactions of Two Tandem Semisubmersible Floating Offshore Wind Turbines Based on FAST.Farm

Wake effects commonly exist in offshore wind farms, which will cause a 10–20% reduction of whole power production as well 5–15% increase fatigue loading on the turbine main structures. Obviously wake interaction between floating (FOWT) is more complicated, and needs careful assessment prerequisite for active control (AWC). The primary objective present research to investigate detail how inflow condition, streamwise spacing, turbulence intensity, shear influence performance, platform motion dynamic structural FOWT. FAST.Farm, developed by National Renewable Energy Laboratory (NREL), was used simulating two tandem FOWTs different conditions. Comparisons were made conditions performance dynamic, presented through both time frequency domain analysis. Damage equivalent loads change interference under typical working discussed summarized. Half would pose many challenges downstream These studies can be incorporated into further farm models, providing applicable AWC strategies reduce higher energy longer life
