An analytical approach has been developed for the study of fatigue life of tubular joints used in offshore structures when random loading conditions are applied. The method is based on linear elastic fracture mechanics and surface fatigue crack propagation. Using the line-spring element method, stress intensity factors of a part-through surface crack are computed. Crack propagation under random loading conditions with distribution parameters is calculated leading to fatigue life prediction if the statistical characteristics of random loading conditions are known. This method can be also used in predicting the remaining lives of tubular joints when cracks are detected and random loading conditions are applied.
