Sammanfattning/Abstract: Results of a FE analysis of action of an ice sheet on a wind turbine plant are presented and a short review of ice material properties from literature is presented.
The purpose of the FE analysis is to obtain the ice crushing loads on a vertical offshore wind turbine structure caused by the ice sheet movement. The main parameters for comparing the results are ice thickness and ice compressive strength. The result is that when ice thickness and ice compressive strength are increased, the total crushing force increases.
In the other part, a short review is presented of the literature on ice physics; material properties; and theoretical ice crushing force formula on vertical and sloping offshore structure. Also maps of ice condition in the Baltic Sea are presented.
