1. Introduction
Floating wind turbines (FWTs) are an emerging technology which can be used to generate electricity from the significant wind resource in relatively deep water (>50 m). Model tests are an important part of the qualification process for such novel concepts, but there are challenges related to scaling physical tests including both wind and waves. Hydrodynamic tests generally follow Froude scaling, but a consistent scaling of the wind turbine will then result in low Reynolds number and generally poor aerodynamic performance. Although non-geometrical scaling
