A better understanding of the complex physics influencing large offshore wind farms can deliver significant cost savings. This is one of the main goals of the Hiperwind project [1]. The present study focuses on the uncertainty evaluation of the Blade Element Momentum (BEM) aerodynamic approach, widely used for aero-servo-hydro-elastic models during design studies. A comparison between BEM and vortex-based model is conducted for two different offshore technologies: a fixed 2.3 MW installed on a monopile and a future generation IEA-15MW mounted on a modified UMaine floater. As a result, a well-fitted uncertainty metamodel is obtained, and it is found that the uncertainties of the BEM are higher for the floating wind turbine case
