This paper presents a comprehensive hydrodynamic analysis of the CENTEC-TLP tension leg platform supporting a 10 MW wind turbine. Numerical simulations are conducted using the potential flow software AQWA, incorporating viscous damping corrections and an equivalent tower stiffness approximation. The primary objective is to validate the numerical simulations of the tension leg platform under various wave conditions. Initially, numerical simulations are performed in the frequency domain, comparing the platform's resonant periods and responses in transport condition with existing numerical results from the literature. Subsequently, the system's natural frequencies in its installed condition are assessed through decay test simulations in calm water, both with and without tower stiffness. The dynamics of the installed platform are then examined in the time domain under various regular wave conditions, with motion and mooring tension results compared to model-scaled experimental data. The numerical results show a reasonable correlation with experimental results, particularly when using tower approximation, which significantly improves pitch motion and tension predictions. This indicates that the pressure predictions on the platform are acceptable and suitable for integration into subsequent structural models for stress analysis under dynamic loads.
