Abstract The objective of this project was to examine the existing practice for establishing the reliability of offshore structures. Specifically, it examines whether ignoring the risk of platform collapse from multi-member failure is significant or not. Probabilistic fracture mechanics calculations are used to predict the probability of individual member failures and the effects of stress redistribution on the integrity of neighbouring joints are examined. The report concludes that multimember failures may result in large reductions in platform strength which can have a significant effect on platform reliability predictions.
