Comparison of Ice Load Models in Ice-structure Interaction Simulation for Offshore Wind Turbines

Research output: Contribution to conferenceConference PosterScientific

Abstract

The Baltic Sea features a potential for large capacity wind farms because of the high and constant wind velocities and mostly shallow coastal regions. Due to the cold climate, the ice loads and the ice induced vibrations present the most significant uncertainties in the offshore wind turbine design. This poster presents two ice load models to investigate ice induced vibrations of the offshore wind turbines. The first one is the PSSII (Program for Soil-Structure-Ice Interaction) (cf. Kärnä et al. (2010)) . The second one is the Määttänen-Blenkarn (cf. Määttänen et al. (1998)) model implemented in the Abaqus simulation software. Load cases with different structural configurations were studied. This included the variations in ice velocities and the sub-structure height. The results showed that PSSII was able to describe the intermittent ice crushing and the lock-in vibrations. The Määttänen-Blenkarn model was suitable for the lock-in vibration.
