Abstract
Regarding the continuous tendency to consume energy throughout the world, societies have propelled to exploit oil and gas. A vast number of offshore structures have been established in the sea to provide needed energy for industries. A good offshore structure design depends on the adequate and fair anticipation of probable occurrences during its service life. Fatigue damage is one of the most important problems that offshore structures see before happening failure in structural components. Typically, fatigue life span is predicted by two, S-N curve and fracture mechanics approaches. However, due to the presence of structural and environmental uncertainties, the probabilistic method is highly recommended to have an accurate fatigue life prediction for offshore structures.
