Damage Review and Risk Assessment of Midstream Amine Processing Units

Sep 24, 2024

Authors: Brian McNeill, Staff Engineer II; Shane Kelliher, Staff Engineer I

For those who had the opportunity to watch last week’s webinar presented by Brian and Shane, this article expands on the benefits of risk-based inspection (RBI) for amine processing units and offers a multidisciplinary approach. It begins with an overview of the process and rich/lean amine loading, identifies key damage mechanisms and areas of concern, and proposes options for corrosion mitigation.

Advancements in Risk-Based Inspection Strategies for Ammonia Storage Tanks

Apr 30, 2024

Authors: Maria Rennillo, Engineering Solutions Lead, Staff Engineer II; Matthew Kaiser, E.I.T., Staff Engineer I; Katelyn Gustoff, Consulting Engineer II

Developing a repeatable, in-service inspection strategy for ammonia storage tanks is difficult; however, it will help improve operational reliability and minimize the probability of failure from several damage mechanisms, including ammonia stress corrosion cracking (SCC). In this article, the authors discuss Equity’s multi-disciplinary approach to navigate the challenges of these high-consequence ammonia storage tanks. Read how we integrate risk-based inspection (RBI), fitness-for-service (FFS), and materials and corrosion expertise to provide a comprehensive and practical inspection strategy.

Understanding Damage Mechanisms in Industrial Gas Applications

Mar 26, 2024

Author: Phillip Prueter, Principal Engineer II

Metallurgy and corrosion experts a key to identifying damage mechanisms and predicting corrosion rates for equipment used in processes like steam methane reformers (SMRs) and air separation units (ASUs). In this article, you’ll read how important it is to recognize which damage mechanism can be reasonably captured with risk-based inspection (RBI) methods and which ones require more detailed analysis using FFS principles. In addition, you will also gain insights into how to create robust mechanical integrity programs for industrial gas production units.

The Art of Database Maintenance: Optimizing IDMS QA/QC

Mar 24, 2023

Author: David M. Rivers, E.I.T., Staff Engineer II

We’ve all heard the term “garbage in, garbage out.” When managing an inspection data management system (IDMS), it’s important to implement a quality assurance (QA) and quality control (QC) process to keep the data clean and optimized. In this article, you’ll read how E²G has leveraged its expertise with developing QA/QC processes and automated QA tools to help our clients raise the bar on IDMS data quality.

Uninspectable Risk

Mar 24, 2023

Author: Lawrence I. Cleland, RBI Group Head, Staff Engineer II

The purpose of RBI is to inspect all equipment and components as efficiently and targeted as possible; however, how do you perform RBI on an asset that will always call for inspection? In this article, you’ll read about an incredibly important and complex, although misunderstood, aspect of RBI — uninspectable risk. Lawrence Cleland provides a deep dive into uninspectable risk and discusses how to develop a well-considered asset management strategy to help you save money and reduce the number of unnecessary inspections.

Aboveground Storage Tank Overfill Prevention – Updated Standards, Regulatory Focus, and E²G Services

Mar 29, 2022

Author: Joel L. Andreani, P.E.

This article discusses how the combination of the changes in the fifth edition of API 2350, Overfill Prevention for Atmospheric Storage Tanks in Petroleum Facilities (2020), and the adoption of this standard by various regulatory bodies has put additional requirements for overfill prevention on owners/operators of AST facilities.

Tank RBI, Not Just an Inspection Deferral Tool

Jul 27, 2021

Author: Joel Andreani

Learn how applying quantitative RBI principles to storage tanks will result in optimized inspection intervals and reduced risk of loss of containment. This article discusses the difference between qualitative and quantitative tank RBI and how tank RBI is a central part of a facility’s overall tank integrity management program (IMP).

Turnarounds: Executing a Problem-Solving Team

May 25, 2021

Author: Kraig S. Shipley

A successful turnaround has five main stages: setting goals, project scoping, detailed planning, execution, and post-turnaround planning. This article focuses on the advantages of a problem-solving team to resolve equipment inspection discovery and efficiently minimize lost opportunity costs.

The Importance of Pre-Turnaround Reviews

May 25, 2021

Authors: Paul J. Kowalski; Brian L. Jack

A turnaround can cost hundreds of thousands or even millions of a dollars per day. In this article, you’ll learn how Risk-Based Inspection (RBI) helps to manage the costly impact of turnarounds through proper pre-planning to minimize the overall downtime.

Q&A: Structural Integrity Programs

Apr 27, 2021

Authors: Derek Slovenec; Joel Andreani

Aging or deteriorating structures, foundations, and other infrastructure cost U.S. businesses billions of dollars each year. Problems with structures and foundations are often a result of design flaws, construction defects, deteriorating conditions, extreme environmental events, and/or changes in applied loads.
