Abstract
Using data obtained from open-sea testing of the 1:6.5 scale prototype of the SWAY hybrid tension-leg spar-type floating wind turbine, a FAST model of the SWAY system was built and validated. Significant in the validation process were improvements to the FAST wind turbine simulation tool to incorporate wind loading on the turbine tower for floating systems. Simulations were performed with and without the new tower-load capability to examine its influence on the response characteristics of the system. This is important in situations when the turbine is parked in survival conditions. The simulation results were then compared to measured data from the SWAY system in both turbine operating and nonoperating conditions. Mixed results were observed when comparing the simulated system behavior to the measured data, but the tower wind loads improved the comparison for nonoperating conditions.
