The wide shallow bucket foundation with concrete arc transition section is subjected to significantly larger wave loads which will easily affect the vibration response of the entire structural system. For an offshore wind turbine (OWT) supported by bucket foundation, a finite element model of the whole wind turbine was established based on the measured vibration data, and then the influence of wave loads on the vibration response of the tower top of the OWT supported by bucket foundation was simultaneously analyzed through the established finite element model. It is shown in the analysis results that the vibration response of the tower top caused by wind load is greater than that caused by wave load during the operation period. Subsequently, the influence of the wave load can be ignored compared to the wind load when the wave height is small. In addition, the impact of wave loads on the vibration response of the tower top increases with the increase of external wind speed and wave height and the corresponding impact on the vibration displacement response of the tower top is greater than the vibration acceleration.
