In order to evaluate the Safety of offshore fixed platforms in service, the fatigue reliability calculation for structure members is necessary. The paper analyzes the alternating stress due to sea wave and ice force, and provides new pre-processing programs of hot spot stress calculation. Then the paper presents the fatigue life calculations for structure members under low temperature and ice loading and sea wave loading. At last, considering the three random coefficients: stress calculation B, fatigue life experiment K, fatigue damage calculation {Delta}{sub c}, the Fatigue reliabilities of structure members are calculated.
