Fatigue Analysis of Offshore Wind Turbine Mono-pile Support Structure

Abstract

Abstract: WAsP was used to analyze the data of a wind farm and the wind speed distribution was gained. The parameters of wind, wave and current for each working condition were calculated. On the basis of fatigue loads, ABAQUS was used to model the support structure and the stress response time history was figured out through mode superposition method. According to S-N curves, rainflow counting method and Miner’s linear damage theory, Fe-safe was used to work out the fatigue life of the support structure and the effect of different kinds of loads on fatigue life was also researched. The results show that the fatigue life of the support structure meets demand. Wind turbine loads are the key influence factor of fatigue life. Sensible generator control strategy is good for increasing fatigue life. The method that defining working condition through wind direction and 10 minute mean wind speed can be used in fatigue analysis of offshore wind turbine support structure.

Key words: offshore wind turbine, dynamic response, S-N curves, fatigue
