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 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 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.
Ethos has assembled a team of experts who apply what they learned through years of process safety experience in the industry and dealing with OSHA and EPA. Click here to learn more about our services.
This article helps shine light on some common industry problems that can occur by having inferior UT procedures and practices, while providing several lessons learned through a case study that resulted in nearly $1 million in turnaround repairs.
This 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.
This 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.
The 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.
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”.
A 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.
Gasification technology has emerged in oil and gas due to the high combustion energy of Syngas and less environmental concerns than flue gas. This article discusses proper inspection and corrosion monitoring techniques for gasification units.
This 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.
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.
Tanks 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.
A 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.
Welding imperfections vary in impact from being acceptable to requiring repair. It is important to ensure the quality of welds using NDT and to ensure the strength of the entire piping system with hydrotesting.
This article shares examples of where RBI work processes either broke down or were non-existent, or where the user did not fully understand the technology or overall RBI logic and the results.
