In the present study, the numerical modeling and simulations of a Floating Offshore
Wind Turbine (FOWT) are presented. The analyses are carried out utilizing a variety of
open-source codes and run on a High-Performance Computing (HPC) environment. The
analysis is performed on the NREL 5 MW turbine atop the OC3 Hywind SPAR floating
platform. The result shows that the multi-threading computation reduces the computational time for the hydrodynamic platform significantly. Despite using a serial code, the
performance analysis of a single wind turbine can benefit from the batch simulation with
multiple runs for multiple input scenarios. On a wind farm scale, a combination of the
multi-threading and the batch simulations is effective in reducing the computation time.
Extraction of power from the wind causes the wind velocity behind the turbine to be lower
than the ambient velocity. The wake effect is stronger near the turbine downstream of
the rotor. The rotor wake then diffuses and expands as it travels downstream causing
the turbine located further behind the upstream turbine to produce more power than the
closer one. The wake steering performed by yawing the upstream turbine with the correct
yaw angle also proved to be able to increase the collective power production of the wind
farm.
