This paper uses a coupled FAST-OrcaFlex model in order to
explore the impact of simulation duration on model convergence.
The work analyses both operational and extreme cases, assessing
the estimated fatigue and extreme loads experienced by a floating offshore wind turbine and its mooring system. Considering
an OC4 semi-submersible deployed with the NREL 5 MW turbine, the case study performs a parametric sweep over a range of
wind speeds, sea states, and simulation durations. Through this
sweep, the paper establishes the impact of the simulation duration for this particular floating offshore wind turbine and characterizes the convergence properties of the loads and excursions as
a function of the simulation duration. The results inform the selection of simulation durations to be used in coupled aero-hydro
models and optimization frameworks for floating offshore wind
applications and can be used to aid the development of guidance
and standards for coupled floating offshore wind turbine models.
