Abstract

Fatigue reliability of marine structures is an important design consideration both for ship structures, fixed and floating offshore platforms for oil and gas exploration and exploitation. The importance of performing a fatigue resistant design is increased by use of lighter materials and materials with higher static strength and the emergence of designs of structures with significant increase of response due to dynamic effects. Prediction of fatigue life for such structures is encumbered with large uncertainty due to inherent uncertainty in the loading and fatigue processes, due to uncertainty of the process parameters and due to model uncertainty. As a consequence of this, probability based methods for fatigue life prediction are well accepted. Large resources are spent in inspecting marine structures for fatigue cracks. Both visual inspection and expensive NDT methods are applied above and underwater. A probability based decision analysis for resource allocation between material spending in construction and inspection and repair is thus relevant.
