FFS Assessment of Aboveground Storage Tanks - Common Pitfalls and Case Studies

The Equity Engineering Group, Inc., May 13, 2022

Webinar Overview

Fitness-for-Service (FFS) is a recognized industry practice for assessing equipment mechanical integrity when unanticipated damage is found and can often be used to extend service life while minimizing downtime and avoiding costly repairs. FFS can be leveraged in Aboveground Storage Tank (AST) integrity assessment to address common damage such as corrosion and distortion. As with other fixed equipment, the success of an FFS evaluation for an AST relies heavily on the accuracy and availability of the required data inputs. While advances in technology, specifically related to inspection methods, have yielded better, more accurate data, there still exist challenges in this area.

In an effort to help the Inspectioneering community better identify and overcome some of these challenges, we have teamed up with E2G | The Equity Engineering Group, Inc. to bring you FFS Assessment of Aboveground Storage Tanks - Common Pitfalls and Case Studies, a one hour webinar presented by Kate Gustoff, Group Head - Mechanical and Structural Engineering at E2G. The presentation covers storage tank life cycle management using FFS and provides examples of some common pitfalls owner-operators run into when evaluating their aboveground storage tanks for various flaws.

Specific topics discussed include:

  • The application of the API 579-1/ASME FFS-1 (API 579) FFS and API 653 standards for common damage associated with in-service ASTs
  • Common pitfalls in relation to the required data inputs and available assessment methodology
  • Case studies to illustrate these pitfalls and show how FFS techniques can be used to make run-repair-replace decisions and determine remaining life
