The use of ring-stiffened joints in offshore structures is widespread. However, the prediction of the fatigue behavior of these joints is subject to considerable uncertainty and there is a need to identify the principal factors contributing to these uncertainties. This paper includes a survey of the use of ring-stiffened joints in a number of fixed platforms in the United Kingdom sector of the North Sea and a detailed assessment of both the stress concentration factor equations and the S-N curves used to evaluate the fatigue life. The uncertainties associated with the current procedure for the assessment of the fatigue performance of ring-stiffened joints are assessed in the light of the development of the revision to the HSE Fourth Edition Fatigue Guidance.
