  • The probability distributions of ice thickness, ice velocity and flexural strength are determined using the measured and simulated data for the JZ20-2 sea area in the Liaodong Gulf.Using dynamic ice-load function of ice-broken cone, the fatigue ice-load of one offshore platform structure with ice-broken cone is simulated with Monte-Carlo method.The statistical results show that the amplitude and period of ice-load both have lognormal distribution.The joint probability distribution of them is analyzed, which is great valuable to construct the fatigue ice-load for offshore platform with ice-broken cone.The present results can be applied to the probability design and cumulative damage analysis for offshore structure with ice-broken cone in the JZ20-2 sea area in the Liaodong Gulf.
