For the reliability analysis of offshore guyed towers for large storm events, failure of an anchor pile of the guyline system is investigated. Two failure modes of the anchor pile due to the extreme and the cyclic wave loadings are considered. The probability of failure due to the extreme anchor load is evaluated based on the first excursion probability analysis. Degradation of the pile capacity due to cyclic loadings is evaluated by using empirical fatigue curves for a driven pile in clay. The numerical results indicate that the failure probability due to the cyclic loadings can be as large as the risk due to extreme loading, particularly for the cases with the low design safety level of the pile strength and the large uncertainty of the pile resistance.
