Abstract

In order to make the best use of ocean resource and maximize economic benefits, a novel offshore wind turbine （OWT） with a breeding function（MOWTAC） is suggested, which is an integration of monopile OWT and mariculture. In the study, the hydrodynamic analysis model of MOWTAC is proposed based on the time-domain fully couple numerical simulation tool FAST v8, and the coupled analysis model of under earthquake, wind and wave loads is established in the updated FAST v8. Then, the dynamic characteristics and structural responses of MOWTAC under complex environmental conditions are analyzed, and the comparisons are carried out. According to the research, the dominant influence of seismic load on the structural responses of MOWTAC in the time domain is observed. Meanwhile, the influence of the second natural frequency on the structural response of MOWTAC increased significantly under seismic excitations, by comparing with wind and wave loads.
