Resumen

In this paper, a structural reliability assessment of a structural offshore considering the effect of the cumulative damage caused by fatigue at the end of an instant of time is presented. The reliability is expressed in terms of the confidence factor. The confidence factor is obtained for three kinds of approaches: a) without damage, b) the structural capacity is reduced over time and c) the structural capacity and demand vary over time. The uncertainties related to the occurrence of operational and storms loadings as well as epistemic uncertainties are considering. A fixed offshore jacket platform located in the Gulf of Mexico is used to estimate the reliability indicators. The structural demand and capacity are evaluated by considering operational and storm conditions. The damage is defined by the crack growth in tubular members due to fatigue. Undesirable reliability levels are obtained after 9 years of the offshore construction. The evaluation of the structural reliability levels helps to make decisions about design o re-design the structural system.
