How Inferior UT Procedures and Practices on Pressure Vessels Cost $1 Million in Turnaround Repairs – Part 2
January/February 2020 Inspectioneering JournalBy Dave Holthaus at Comprehensive Procedure Reviews, LLC (CPR), and Kevin Gaskin at CHS, Inc.This case study discusses costly repairs that were needed on newly fabricated pressure vessels as a result of poor UT practices. The author shines a light on some industry problems that can be fixed with an understanding of what is actually required.

January/February 2020 Inspectioneering JournalBy Ahmad RK Rana at Integrity Products and Supplies, Inc., and Dr. Zoheir Farhat at Dalhousie UniversityThis article addresses two failure events where inadequate attention to thermal fatigue led to premature equipment failure while specifying guidelines to help prevent such failures that can be a part of a plant's inspection and maintenance programs.
-
The Effect of High Pressure High Temperature and Sour Service Environment on Subsea Dissimilar Joints
January/February 2020 Inspectioneering JournalBy Samer E. Ibrahim at Robert Gordon UniversityThe author will discuss the failure of a dissimilar joint while examining the root causes of the failure along with potential solutions and preventive actions that would not compromise the welding production rate.

November/December 2019 Inspectioneering JournalBy Dr. Timothy Black at Quasset, Maurice Fransen at Shell Global Solutions International BV, and Sieger Terpstra at Shell Global Solutions International BVThis article examines multiple trials that entailed testing robotic systems on different non-magnetic surfaces to identify the feasibility of detecting CUI using robotics in combination with NDE technology.
-
September/October 2019 Inspectioneering JournalBy Tim Haugen at Quest IntegrityThis article presents two cases studies demonstrating how properly conducting baseline fired heater tube inspection aids in early discovery and correction of defects, avoiding unexpected in-service failures, and more.
-
September/October 2019 Inspectioneering JournalBy Ricardo Gonzalez at Total Refining and PetrochemicalsThe author discusses a method being used in most of their refineries and petrochemical facilities that allows them to optimize the scope of NDT during turnarounds, while improving the reliability of bundles.
-
July/August 2019 Inspectioneering JournalBy Robert Sladek at Asset Optimization Consultants, Inc.This case study is intended to demonstrate how a Qualitative Risk Assessment can be a cost-effective and resource-efficient means to prioritize equipment which is often “under the radar”.

July/August 2019 Inspectioneering JournalBy Richard B. Eckert at DNV GL, and Dr. Susmitha Purnima Kotu at DNV GLA significant number of pipeline failures due to external or internal corrosion have resulted from MIC, some with catastrophic consequences. This article demonstrates a three-step failure analysis process used to investigate the failure mechanism.

July/August 2019 Inspectioneering JournalBy Jeannie Lewis at The Equity Engineering GroupThis article provides a case study showing the real costs and effects of having a dated engineering standards program, as well as the financial benefits through increased reliability of having a thriving engineering standards program.
-
July/August 2019 Inspectioneering JournalBy Geoff Clarkson at UTComp, Inc.This article is written to provide a brief case study of an acoustic emission test of an FRP storage tank. A method combining acoustic emission with ultrasonics is proposed to ensure reliable long term operation.
-
July/August 2019 Inspectioneering JournalBy Ana Benz at IRISNDTTanks are ubiquitous and essential in industrial societies. When they fail, the consequences can be dire if products/volumes they store are explosive and/or toxic.
-
May/June 2019 Inspectioneering JournalBy Vibha Zaman, P.E. at Asset Optimization Consultants, and Leomar Penuela at Asset Optimization ConsultantsA well-implemented and managed reliability program incorporating RBI, DMR, and IOWs can identify potential damage mechanisms, optimize maintenance and inspection activities, reduce risks, and improve the governance in managing Ethane Crackers.
