Introduction Developing wind-wave coupled devices is becoming a research hotspot in offshore renewable energy. While previous studies have primarily concentrated on the hydrodynamic performance of such devices, few addressed sediment scouring near foundation, which critical to their safety. Methods Therefore, based design device integrating an fixed wind turbine, model developed using commercial computational fluid dynamics platform Flow-3D ® . The numerical validated experimental test data, and deposition under combined effects waves currents are investigated. Results results indicate that oscillating water column tube array can expand area but minor influence maximum depth. In addition, due sheltered effect tubes, depth piles at far end be reduced. Discussion By optimizing distance between ends seabed, reduced by 22.8%, beneficial safety stability foundation device. key findings this study provide more comprehensive basis for development engineering practice
