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. It can be used to make run-repair-replace decisions to help determine if pressurized equipment containing flaws that have been identified by inspection can continue to operate safely for some period of time. This report provides an interpretation of general and local metal loss assessment procedures which are specified in FFS assessment procedure developed by PAJ⁄JPCA FFS task group based on API RP579 with following three parts Part 1 Overview of FFS assessments and fundamental technology of metal loss assessment Part 2 Study on various assessment procedures and margin for failure Part 3 Comparison of metal loss assessment procedures based on FEM analysis
