Case Studies
Inspectioneering contributors and authors have published numerous mechanical integrity case studies in Inspectioneering Journal and throughout our online resources. This page brings all of these case studies into one location to better help you learn from the experience of others.
This article describes how an international oil and gas company built an inspection data management program for its U.S. operations yielding improved confidence in decision-making information, cost savings through increased efficiency, and an...
The benefits and advantages of drone inspection over other methods have made this technology a viable solution in industry. As utilization of drone technology continues to grow and expand, it’s important to not only understand what they can do but...
With no industry consensus documents in existence that provide guidance for determining FFS of FRP, this article provides a case study that illustrates how an existing European design standard on GRP tanks can be used to calculate expected changes...
This article presents a case study from a Middle Eastern refinery that explores a heat exchanger that failed unexpectedly after five years in service. There are multiple initiators that can cause under deposit corrosion (UDC) in heat exchangers in...
This article details the experience an oil company had when using FEA to evaluate the implications of a damaged pipeline. Specifically, it presents an efficient method that combines analytical techniques with FEA to determine the pipeline’s...
There is concern in the industry over recent findings of reduced toughness fittings and flanges at risk of brittle fracture. This article provides an overview; possible contributors; measures taken to address; and a proposed FFS approach to address...
HTHA of hydrogen-containing equipment can be prevented with appropriate material selection and fabrication, appropriate welding procedures, regular inspection of equipment using proven, effective technologies and equipment operated by qualified...
This article features a case study on the feasibility of a wall-sticking drone for effectively conducting ultrasonic testing and other NDT methods on equipment at elevated heights.
Implementing RBI for process piping can be a very tedious and lengthy exercise, especially for major process plants with thousands of feet of interconnected piping. This article shares the experience of ADNOC LNG following a structured RBI approach...
Most of us that work integrity and reliability understand what we do and how we do it. But how many of us understand WHY we do things? Understanding the motives behind our activities, initiatives and programs can help to galvanize and lay a...

Given the concern throughout industry regarding the potential for brittle fracture failures, PWHT guidance to address potential issues arising from the recent changes in PWHT code requirements for carbon steel is examined in this article, and...
This article explains the Statistically Active Corrosion Assessment, which is a tool for determining appropriate and realistic corrosion growth rates which can assist pipeline operators in optimizing the value of in-line inspection data.
This article, part two in a series, provides a case study of an inspection and evaluation of a Fiberglass Reinforced Polymer (FRP) column using nondestructive ultrasound readings on the outer surface of the FRP.
In-service equipment failures present a considerable challenge to reliability engineers. This article presents a case study of a convection tube failure in a furnace and the analyses that were performed to understand the root cause and determine the...
Although value-drivers often differ between facilities, all can agree that effective asset management strategies should lead to better decision making. In this case study, the authors detail how process-based risk management strategies can make for...
