To address the limitations of expanding offshore wind farms in Belgium, the strategy of integrating floating solar photovoltaic (PV) systems and wind farms has emerged as a viable solution to increase power generation while using the same sea surface. In this study, large-eddy simulations (LES) of wind farms are performed through the ExaWind open-source codes, AMR-Wind and OpenFAST. First, the numerical framework is tested against experimental data and other LES solvers within the SWiFT Neutral Benchmark. Strong agreement is noted in horizontal wind speed and turbulence intensity, indicating that the atmospheric boundary layer is accurately captured. However, generator power and torque exhibit greater variability, with a tendency to overestimate compared to experimental measurements.
