Welcome!

Storage tanks are essential equipment at processing facilities and terminals, regardless of industry.  This month, we are looking at how you can improve the reliability and safety of aboveground storage tanks by applying fitness-for-service (FFS) or risk-based inspection (RBI) techniques to your operations and maintenance programs.  


Fitness-for-Service for Aboveground Storage Tanks 

Author: Katelyn J. Gustoff, Consulting Engineer I

FFS assessments are recognized as an integral tool for the effective life-cycle management of equipment.  In this article, Katelyn Gustoff explores applying the API 579-1/ASME FFS-1 (API 579) FFS standard to aboveground storage tanks and shares several case studies to illustrate how FFS techniques can help you make informed run-repair-replace decisions for a facility’s storage tanks.

Tank RBI, Not Just an Inspection Deferral Tool

Authors: Joel L. Andreani, P.E., Senior Vice President of Consulting Engineering, Principal Engineer II

It is costly and time-consuming to inspect storage tanks.  Joel Andreani discusses the difference between qualitative and quantitative tank risk-based inspection (RBI) and how tank RBI is a central part of a facility’s overall tank integrity management program (IMP).  You will learn how applying quantitative RBI principles to storage tanks will result in optimized inspection intervals and reduced risk of loss of containment.

  • The Importance of Pre-Turnaround Reviews
    Authors: Paul J. Kowalski, Staff Engineer I and Brian L. Jack, Principal Engineer II

    Efficient completion of the turnaround (TA) work scope (i.e., scheduled maintenance) is arguably one of the largest factors in determining if a given site will satisfy the annual budget. Of course, opportunity feedstocks, increased charge rates, unplanned shutdowns, among many other items can significantly impact the annual budget.
