Dynamic Responses of an Offshore Floating Photovoltaic Array Under Wind and Wave Conditions

Type: article
Abstract: To clarify the relationship between offshore floating photovoltaic (FPV) platform motions and mooring loads under combined wind and wave conditions, a numerical model based on three-dimensional potential flow theory was established to study the dynamic responses of a 4 × 4 offshore FPV array. Time-domain statistics and spectral analysis show that higher wind speed increases the mean surge offset. As wind speed rises from 10 to 15 m/s, the maximum and standard deviation (STD) of mooring line tension increase by 59.4% and 117.8%, respectively, while the low-frequency surge response weakens. Higher turbulence intensity increases the low-frequency peaks in the surge and mooring line tension spectra. As the spectral peak period increases, the heave and pitch spectral peaks shift toward lower frequencies. The wave-frequency surge response also becomes more pronounced. Higher significant wave heights amplify heave and pitch motions and mooring line tension, while weakening the low-frequency surge response. Across all cases, the end platforms have larger heave ranges; as surge displacement increases in the wave propagation direction, the wave-facing platform descends slightly and the wave-sheltered platform rises.
