Fitness-For-Service (FFS) assessments are quantitative engineering evaluations that are performed to demonstrate the structural integrity of an in-service component that may contain a flaw or damage. This training course is designed to give a detailed discussion of the subject of Fitness For Service concepts (FFS) with emphasis on the basic degradation mechanism and its consequences aspect.

It presents a thorough understanding of how the disciplines of material science, stress analysis, NDT and inspection practices can be applied for assessing the present structural integrity of the component, and deciding its fitness for continued service as well as the projected remaining life. This course covers the analytical methods and their applications are explained with numerous case studies. In order to suit the course to participants with or without a FFS background, the course will be delivered such a way that most of technical terms and both code statements and examples will clarify concepts.
