Inspectioneering JournalBy Ibrahim Kodssi at ADNOC LNG, and Houssam Sabry at ADNOC LNGImplementing 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 for piping groups.

Inspectioneering JournalBy Phillip E. Prueter at The Equity Engineering Group, Inc.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 commentary on the potential reduction in fracture toughness due to PWHT is provided based on a review of published literature.

Inspectioneering JournalBy Greg Alvarado at Inspectioneering JournalMost 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 foundation for long term success.

Inspectioneering JournalBy Elizabeth Allen at DNV GL, and Michelle Havlock at DNV GL
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, remediation programs and excavation costs, and determine a re‑inspection interval; all while maintaining safety.

Inspectioneering JournalBy James R. Widrig at Quest Integrity GroupIn-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 remaining tube life.

Inspectioneering JournalBy Daniel Cypriano at Petrobras, and Henrique Ventura at PetrobrasAlthough 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 improved use of equipment.

Inspectioneering JournalBy Michael Turnquist at Quest Integrity GroupThis article outlines the engineering and assessment methodologies applied during the analysis of a failure of a 15-foot diameter reactor tank supported by four legs.
-
Inspectioneering JournalBy Hossam Aboegla at Lloyd's Register EnergyAsset integrity and life cycle management are unique but intertwined concepts. The dynamic process between these principles has a significant impact on the lifecycle of individual assets and, therefore, the integrity of an entire plant.

Inspectioneering JournalBy Mark Geisenhoff at Flint Hills Resources, Jonathan D. Dobis at The Equity Engineering Group, Inc., Phillip E. Prueter at The Equity Engineering Group, Inc., and Dr. Michael S. Cayard at Flint Hills ResourcesThis article summarizes a recent finite element analysis (FEA)-based study that employs creep simulation techniques to investigate the elevated temperature response of piping with peaked longitudinal weld seams.

Inspectioneering JournalBy Melissa Ramkissoon at PetrotrinAboveground Storage Tanks (AST) are essential to any successful oil and gas operation and must be properly managed to ensure operations function in a safe and reliable manner. In this 2-part series, I will identify some common failures related to ASTs in crude oil service and recommend strategies to prevent and/or mitigate such failures.

For many years, it has been common practice in the petrochemical industry to use fitness-for-service (FFS) evaluations to determine whether or not a finding during an inspection would prevent a part from being able to be returned to service.

Inspectioneering JournalBy Gerrit M. Buchheim, P.E. at Becht Engineering Co., Inc.High Temperature Hydrogen Attack (HTHA) is a complex damage mechanism that continues to defy investigators trying to make predictions on the anticipated degree of damage or service life. This article provides some background on HTHA, discusses some current developments in HTHA inspection and mitigation, and describes how one Refiner is instituting an HTHA risk management plan for its refineries and the challenges and pitfalls they have encountered.

Inspectioneering JournalBy Tim Hill at Quest Integrity GroupFor the past 30 years, infrared (IR) thermometry has been used to monitor tube metal temperatures in refining and chemical furnaces. Tracking temperature levels and variations determine performance capability limits and reliable tube life. However, the application of IR thermometry has often been characterized as highly operator dependent, which can result in less-than-optimal data accuracy as a consequence of poorly applied and interpreted results.
