Abstract: The study was based on a new-type truss foundation for the offshore floating wind turbine. First, this paper analyzed
the fully coupled dynamic response of deep-sea wind power system, and studied the influence of different wind-wave incident
angles on the dynamic response of the truss foundation floating wind turbine. Then, it simulated the dynamic response of the truss
foundation floating wind turbine under the extreme sea conditions. The results show that there is a coupling effect between the
structural parts of the truss foundation floating offshore wind turbine; the change of the incident angle of the wind wave has a great
influence on the roll, pitch and roll response; the heave, pitch, and dynamic pitch angles of the truss foundation floating offshore
wind turbine meet the requirements under 1 -year and 50 -year extreme sea conditions. It is proved that the truss foundation
floating offshore wind turbine has good stability.
Key words: truss foundation; offshore floating wind turbine; coupled dynamic response; incident angle; extreme sea conditions
