Realizing the critical importance the role physical experimental tests play in understanding the dynamics of floating offshore wind turbines, the DeepCwind consortium conducted a one-fiftieth-scale model test program where several floating wind platforms were subjected to a variety of wind and wave loading conditions at the Maritime Research Institute Netherlands (MARIN) wave basin. This paper describes the observed behavior of a tension-leg support platform (TLP), one of three platforms tested, and the systematic effort to predict the measured response with the FAST simulation tool using a model primarily based on consensus geometric and mass properties of the test specimen. The initial model was tuned through adjusting damping and stiffness of the platform and tower using free-response test results.
