Abstract
The calculation of loads for floating offshore wind turbines requires time-domain integrated simulation tools where most of the physical concepts involved in the system dynamics are considered. The loads at the different components are used for the structural calculation and influence the design noticeably. This study quantifies the influence of mooring dynamic models on the calculation of fatigue and ultimate loads with integrated tools and compares its performance with lower computational cost mooring models as the quasi-static. Three platforms representing the principal topologies (spar, semisubmersible and TLP) were assumed to be installed at the same 200 m depth location in the Irish coast. For each platform, the fatigue and ultimate loads were computed with an integrated floating wind turbine simulation code using both, a quasi-static and a fully dynamic moorings model. More than 20,000 load cases were launched and postprocessed following the IEC 61400-3 guideline and fulfilling the conditions that a certification entity would require to an offshore wind turbine designer. The results showed that the impact of mooring dynamics in both fatigue and ultimate loads increases as elements located closer to the platform are evaluated; the blade and the shaft loads are only slightly modified by the mooring dynamics in all the platform designs, the tower base loads can be significantly affected depending on the platform concept, and the mooring lines tensions strongly depend on the lines dynamics both in fatigue and extreme loads in all the platform concepts evaluated.
