Uncertainty evaluation of BEM approaches for offshore wind turbine design
Abstract
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
