Abstract:

This paper investigates scaling laws that were adopted for the
DeepCwind project for testing three different floating wind systems at
1/50 scale in a wave tank under combined wind and wave loading. The
1/50 scaling of the full-scale 5-MW wind turbine system is performed
based on Froude scaling laws, which are commonly used for offshore
structures. The scaling approach adopted is verified through FAST, an
aero-hydro-servo-elasto dynamic modeling tool, by comparing the
consistency of simulation results between model and full scale. The
Froude scaling approach does not maintain proper Rey
