With the continuous development of offshore floating wind turbines, their positioning ability has gradually attracted the attention of academia and engineering. The freak wave is destructive to the floating structure because of its large energy, strong suddenness and prominent nonlinear characteristics. In this paper, the new Moray-Base floating wind turbine concept designed by Maridea Company is taken as the research object, and the finite element model with a mooring system is established based on the potential flow theory. In order to improve correct the accuracy of the numerical model, the physical model test of the pool was carried out, and five sets of mooring schemes were designed to study the positioning ability of the numerical model improved by the physical model test. This paper focuses on the motion response and mooring line tension characteristics of five mooring schemes under the action of freak waves, which provides a reference for the design of floating wind turbine mooring system.
