Abstract

In order to ensure the stability of the floating wind turbines in the complex marine environments, the motion response characteristics should be considered during floating body in the design. In this paper, the X30 floating wind turbine floating body of X1 wind company is taken as the research object, and the hydrodynamic characteristics of the floating wind turbine floating body system are studied by combining model tests with numerical analysis. Firstly, a time-domain fully coupled analysis method is used to analyze the hydrodynamic characteristics of the floating body of the floating wind turbine through the model test. To address the issue of excessive motion response （especially the heave response） is too large, four different heave plate structures are added under the bottom of the column structure of the floating foundation of the wind turbine. Using the model tests, the control effect of motion response under different heave structures is primarily investigated. At the same time, the natural period, measured damping, different wave height characteristics and period sensitivity of motion response of floating body under different heave plate structures are studied. Secondly, the wave loads on different heave plate structures are analyzed by numerical analysis after model test corrections, and the wave load characteristics of heave structures are obtained. Based on the optimized heave plate structure, the heave motion control effect under the action of freak waves conditions is studied.
