IceRisk is a tool developed by Kjeller Vindteknikk to estimate the probability of ice throw from wind turbines. The result is presented as probability maps showing how the probability of ice impact varies within the wind farm. The frequency distribution of the wind speed and of the wind direction during the periods when ice throw is likely to occur is considered in the development of the probability map. The local topography is also considered since the flying distance of the ice fragments depends on the terrain slope.
The result can also be complemented with a risk assessment performed in cooperation with Lloyd’s Register Consulting (Scandpower Risk Management). An IceRisk analysis is relevant for licensing purposes, and in the development of risk preventive measures. IceRisk may also be used to assess the probability of falling ice from telecommunication masts.
