Transient response of a TLP-type floating offshore wind turbine under tendon failure conditions

Haoyu Wu et al.

Summary: This paper investigates the transient effects of one-tendon failure on the system responses of tension leg platform (TLP) floating wind turbines using the WindStar TLP system as a representative example. The results show that under operational conditions, several transient responses of the FOWT may exceed extreme values, and inappropriate shutdown strategies could threaten the safety of the closest tendon to the broken one. These findings have implications for the ALS design of TLP FOWTs.

Dynamic analysis of a novel semi-submersible platform for a 10 MW wind turbine in intermediate water depth

Zhixin Zhao et al.

Summary: This study proposed a conceptual semi-submersible platform for supporting a 10 MW wind turbine in moderate water depth, and evaluated its intact stability through fully coupled analysis. The results showed that the proposed concept FOWT exhibited good stability, with shutdown fault conditions having the most significant impact on its dynamic behaviors.

Numerical and experimental investigation of breaking wave forces on a monopile-type offshore wind turbine

Xinmeng Zeng et al.

Summary: Monopiles are commonly used for offshore wind turbines, and this study examines the impact of breaking waves on monopile-type turbines at different locations. The study used numerical and experimental methods to validate the numerical model's accuracy, showing good agreement between data and predictions. Results indicated variations in wave force at different monopile locations and provided insights into wave breaking evolution and impact kinematics.
