Where is FFS Assessment applicable?
-
Introduction to Fitness-For-Service Assessment Using API/ASME Standard API 579-1 / ASME FFS-1
Asset lacks original design information or it may have exceeded its useful life
When is FFS Assessment needed?
-
Introduction to Fitness-For-Service Assessment Using API/ASME Standard API 579-1 / ASME FFS-1
When is FFS Assessment needed?
Assets manufactured before 1987, equipment operate at relatively low temperature - exposed to self-refrigeration
-
Introduction to Fitness-For-Service Assessment Using API/ASME Standard API 579-1 / ASME FFS-1
When is FFS Assessment needed?
Decommissioned asset that may be used in a different service
-
Introduction to Fitness-For-Service Assessment Using API/ASME Standard API 579-1 / ASME FFS-1
When is FFS Assessment needed?
Equipment operating in either high temperature and/or cyclic service
-
Introduction to Fitness-For-Service Assessment Using API/ASME Standard API 579-1 / ASME FFS-1
When is FFS Assessment needed?
Asset that have undergone any event that might have affected its serviceability like: temperature excursions, overloads, different feed/external environment or a fire.
-
Introduction to Fitness-For-Service Assessment Using API/ASME Standard API 579-1 / ASME FFS-1
When is FFS Assessment needed?
Inspection findings revealed a condition that may impact the future operation of the asset, such as metal loss, distortion (misalignment, out of roundness, bulges or dents), laminations, cracking or blisters, etc.

Fitness-For-Service Background
Before 2000 there were no standards or Recommended Practices on Fitness-For-Service Assessment
The Materials Properties Council initiated activities in 1991 as a Group Sponsored Project
Original Scope - evaluate pressurized equipment in the refinery and petrochemical industry. Then extended to other industries.
First edition published in 2000 as API Recommended Practice API RP 579
ASME/API Joint Committee start activities in 2003. Second Edition of document ASME/API Standard published in 2007 (API 579-1/ASME FFS-1). Example problems published in 2009 (API 579-2/ASME FFS-2)

Scope of FFS Assessment per API/ASME Standard API 579-1 / ASME FFS-1
Assessment or re-rating of components designed and constructed to:
ASME B&PV Codes Section VIII Division 1 & 2
ASME Codes Section I
ASME B31.3 Piping Code
ASME B31.1 Piping Code
API Standards:
API 650
API 620
Other recognized codes and standards, including International Standards (review attributes/compare to API & ASME codes)
Methods and procedures intended to supplement API 510, API 570, and API 653

Introduction to Fitness-For-Service Assessment Using API/ASME Standard API 579-1 / ASME FFS-1
Guidelines to make run-repair-replace decisions of in-service equipment are required
What happens to in-service equipment?
Time dependent degradation Upset operating condition (Pressure, Temperature) Fluid - Material Interaction
Inspection (original fabrication and in-service flaws) Maintenance (including repairs and replacement)
What need to be done?
