Tension leg platform (TLP) floating wind turbines (FWTs) experience high-amplitude, dynamic structural vibrations under complex loading conditions. Tuned mass dampers (TMDs) are a simple yet effective means to reduce such loadings. This work focuses on load reduction by TMDs for the WindStar TLP system, and optimizes the TMDs' parameters in a parametric study. Dynamic analysis then assesses FWTs with and without a TMD in a selected set of load cases. Results show that optimized TMD can reduce nacelle acceleration by up to 20%, especially in extreme conditions.
