Abstract

Highlights
•Offshore wind turbine loads are more sensitive to environmental inputs' uncertainties.
•The set of the most influential factors varies with the design load case considered.
•Turbulence intensity and wave loads uncertainties govern operational loads.
•Soil have significant nonlinear or interactive effects during parked or idling cases.
