Abstract: During the lifetime of a floating offshore wind turbine (FOWT), freak waves may lead to complicated dynamic responses in both the foundation and flexible upper structures. In this study, an optimized phase modulation method is developed to obtain the freak wave profile. The effects of freak waves on a 10 MW FOWT under rated operating and extreme shutdown conditions are studied. Motions of the foundation and structural response of the blades are carefully examined, considering nonlinear geometric stiffness. Under the impact of the freak wave, foundation motions are increased with different timings of maximum amplitude. The tip displacement and root bending moment of blades are more sensitive to freak waves under the rated operating condition compared to the extreme shutdown condition. A comparative analysis between the Euler–Bernoulli beam model and the geometrically exact beam model considering nonlinear geometric stiffness is also conducted. [ABSTRACT FROM AUTHOR]
