Description
Summary:ABSTRACT NEG Micon's Yttre Stengrund Offshore Wind Turbines in the Kalmarsund, Sweden, are supported on unique foundations designed by AMEC. The chosen foundation comprised a steel monopile secured into a rock socket drilled out beneath a deep layer of overlying soil. Sea-ice loading and fatigue governed the design. To minimise the sea-ice loads the foundation was fitted with an ice protection shield. In order to achieve the required fatigue life, time domain simulations were conducted to determine the response of the turbine to combined wind and wave action. Details of the fatigue analyses and methods used to calculate the sea-ice loading are presented herein.
