Abstract

Integration of multiple offshore renewable energy converters holds immense promise for achieving cost-effective utilization of marine energy. Integrated Floating Wind-Current Energy Systems (IFESs) have garnered considerable attention as a means to harness the abundant wind and marine resources in deep-sea areas using a single device. However, the dynamic responses of IFESs are significantly influenced by the coupling of aerodynamic and hydrodynamic loads. To assess the performance of a 10 MW + Spar-type IFES under wind-wave-current loadings, this study develops an aero-servo-elastic model within the hydrodynamic analysis tool AQWA. By utilizing the fully coupled model, this study investigates the platform motions, tower loads, and power production of the IFES under various environmental conditions. A comparative analysis is conducted by comparing the results with those obtained for a floating offshore wind turbine (FOWT). Furthermore, fatigue damage at the tower base of both the IFES and FOWT is evaluated. It is found that the presence of current turbines leads to improved platform stability, significant increases in total power production, and reduced fatigue damage at the tower base. These novel findings corroborate the potential and advantages of IFES concepts in enhancing the stability and energy harvest efficiency of floating marine energy converters.
