The objective of this study is to evaluate fatigue damage and fatigue life of offshore structures using different fatigue calculation methods. Of interest in this study is to identify an efficient method for fatigue calculation of the offshore structures by comparing the Simplified approach, the Spectral approach, and the Fracture Mechanics approach provided in API [3], DNV [5], ISO [7], and ABS [2] guidelines/standards. Fatigue calculations use advanced application tools including SACS [10] and Abaqus [11] coupled with in-house tools. An efficient path in providing safety in structural integrity management is presented in this paper, which can minimize the cost and improve time management for a variety of projects.
