  7. Abstract:
  8. In this study, a hybrid offshore renewable energy system comprising a floating wind turbine platform of the spar type integrated with two distinct types of wave energy converters (WaveStar and PitchFloat) was investigated from a hydrodynamic perspective. The primary objective of the research was to evaluate the dynamic behavior and hydrodynamic responses of the hybrid system under both regular and irregular wave excitations, and to compare its performance with alternative configurations, including a standalone wind platform and hybrid systems utilizing only one type of wave energy converter. To this end, numerical simulations were carried out in both the frequency and time domains using ANSYS AQWA software, based on linear potential flow theory. Key parameters such as added mass, radiation damping, wave excitation forces, and dynamic responses including surge, heave, pitch, and mooring line tension were examined. The results indicate that the integration of wave energy converters into the floating platform, under certain conditions, can reduce motion amplitudes and enhance system stability. Notably, the dual-converter hybrid configuration demonstrated a balanced and moderate performance across various loading scenarios, achieving improved motion stability and reduced mooring line tension. Furthermore, statistical and spectral response analyses under irregular wave loading revealed that the spatial arrangement and type of converters significantly influence the system's dynamic response and energy performance. These findings can contribute to the optimal design of future hybrid marine energy systems
