Summary:The offshore wind turbine (OWT) tower is the important support of the whole wind turbine components, it is necessary to design and research the tower reasonably in order to ensure reliable operation of the OWT. In this paper, 3MW OWT tower is chosen as the object of study. A gas-liquid-solid model of the OWT tower and its external environment is built using COMSOL Multiphysics software. Combined with the two-phase flow theory of gas-liquid, loads of the tower under the coupling action of wind and wave are computed, which provides a new direction for the load analysis of the tower. The results calculated by this method are closer to the physical truth, which provides a more reliable basis for analyzing the fatigue life of the tower further.
