This is one of the main goals of the Hiperwind project [1]. The present studyfocuses 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 andvortex-based model is conducted for two different offshore technologies: a fixed 2.3 MW installed on amonopile and a future generation IEA-15MW mounted on a modified UMaine floater. As a result, awell-fitted uncertainty metamodel is obtained, and it is found that the uncertainties of the BEM arehigher for the floating wind turbine case %G English %2 https://ifp.hal.science/hal-03890887/document %2 https://ifp.hal.science/hal-03890887/file/EMRsim22_Mayol.pdf %L hal-03890887 %U https://ifp.hal.science/hal-03890887 %~ SDE %~ IFP %~ OPENAIRE %~ GIP-BE %~ EDF
