Abstract
One of the challenges for the development of wind energy in offshore cold-climate regions is atmospheric icing. This paper
examines the effects of atmospheric icing on power production, overall performance, and extreme loads of a 5-MW spar-type
floating offshore wind turbine during power production, normal and emergency rotor shutdown, extreme gusts, and survival
conditions. Atmospheric icing is simulated by using the ice accretion simulation code LEWICE. A CFD method is used to
estimate the blade aerodynamic degradation due to icing. The effects of icing on one, two, or three blades are compared, as are
the effects of atmospheric icing on land-based and offshore wind turbines.
