This study presents the dynamic analysis of the NREL/MIT tension leg platform (TLP) supporting the NREL 5-MW wind turbine using OpenFAST. The simulations represent environmental conditions specific to the Kıyıköy region in the western Black Sea. Selected Design Load Cases (DLCs) cover both response characterization and extreme sea states defined by IEC guidelines. The platform hydrodynamics are modeled using first-order potential-flow theory to capture primary motions and tendon tensions efficiently. Viscous and second-order effects are excluded to emphasize computational performance. Simulation durations are selected to allow consistent comparison. A computational cost assessment is also conducted. Results show that OpenFAST produces stable and realistic platform responses across all conditions while maintaining low computational demand. The study confirms the capability of time-efficient modeling for preliminary assessments of floating wind turbines in regional environments such as Kıyıköy.
