This project is intended to facilitate the technology transfer from PRCI research results and other published work to the fitness-for-service (FFS) standard API 579-1/ASME FFS-1. The covered PRCI research results include: (1) crack/flaw interaction rules and (2) fatigue crack growth rates as expressed by Paris law constants for axially oriented flaws/cracks. The other published work includes: (1) incorporation of weld strength mismatch into stress-based FFS assessment and (2) guidance on performing Level 3 FFS assessment for pipelines subjected to high longitudinal/axial strains.

The primary target audience is the API 579-1/ASME FFS-1 committee, whose actions would be needed to adopt the recommendations in this report into the API 579-1/ASME FFS-1 standard.
