The training session begins with the definition of fitness-for-service (FFS) and introduces the Life-Cycle Management (LCM) framework as a process to manage the entire life cycle of fixed equipment including design, construction, in-service use, repair, and retirement. Opportunities for FFS assessments are presented from both the traditional reactive mode and an opportunistic proactive mode. General background information, as presented in Part 1 of the API 579-1/ASME FFS-1 Fitness-for-Service (API FFS) standard with regards to its scope, organization and use, and the responsibilities and qualifications of the parties involved with FFS assessments, is reviewed. The general eight-step procedure from Part 2 of API FFS is presented, which is used for all of the assessments contained in API FFS and introduces the three common acceptance criteria used in FFS assessments including Allowable Stress/Remaining Life, Remaining Strength Factor (RSF), and the Failure Assessment Diagram (FAD).

The sessions continue with discussion of Part 4 General Metal Loss, Part 5 Local Thin Areas, and Part 6 Pitting Corrosion as found in the API FFS standard. Overview of the applicability and limitations general to all the volumetric procedures is reviewed including flaw type, temperature, and component types, as well as those specific to each type of damage and the associated Level 1, 2, and 3 assessment techniques. The sessions will cover the applicable data requirements and emphasize the importance of documenting original design, operational, and maintenance histories. The required data/measurement techniques used to characterize flaws associated with volumetric metal loss assessments will be covered as well as discussion on the differences and use of the data once collected. Specifically,
The sessions will also include guidance on the importance and means of establishing a remaining life to establish an appropriate inspection interval for the damaged component. Suggested remediation and in-service monitoring techniques will also be covered based on the type of damage under investigation. Requirements of documentation applicable to each of the techniques used in volumetric FFS assessments will be detailed. Select example problems will be presented to help connect the lectures with real-world application of the procedures.
Upon completion of the FFS training course, students will have a basic understanding of the following:
Attendees should have a working knowledge of equipment construction codes and standards, and basic stress calculations.
