Introduction  In order to explore the reasonable wet towing method of three tube jacket foundation and study its self-floating wet-towing floating characteristics，

  Method  the numerical simulation software Moses was used to analyze the static stability and dynamic response of soild-floating body and air-floating body in towing for a certain offshore wind turbine three-bucket jacket foundation in this paper. The differences of static stability and towing characteristics between soild-floating body and air-floating body of three bucket foundation for offshore wind turbine under the influence of the same environmental load were clarified.

  Result  The results show that the static stability of air-floating structure is better than that of solid-floating structure， but the motion response amplitude of solid-floating body is lower than that of air-floating structure.

  Conclusion  We demonstrate the feasibility of the method and it provides some guidance for further application.
