Abstract : This report provides an up-to-date assessment of fatigue technology, directed specifically toward the marine industry. A comprehensive overview of fatigue analysis and design, a global review of fatigue including rules and regulations and current practices, and a fatigue analysis and design criteria, are provided as a general guideline to fatigue assessment. A detailed discussion of all fatigue parameters is grouped under three analysis blocks: (1) Fatigue stress model, covering environmental forces, structure response and loading, stress response amplitude operations (RAOs) and hot-spot stresses; (2) fatigue stress history model covering long-term distribution of environmental loading; and (3) fatigue resistance of structures and damage assessment methodologies The analyses and design parameters that affect fatigue assessment are discussed together with uncertainties and research gaps, to provide a basis for developing strategies for fatigue avoidance. Additional in-depth discussions of wave environment, stress concentration factors, etc. are presented in the appendixes. ...
