May/June 2021 Inspectioneering JournalBy Martyn Cooper at SantosThis case study of a CO2 absorber tower in a remote location investigates the use of a new type of wireless ultrasonic sensor for monitoring the thickness of equipment while on or offline.
-
May/June 2021 Inspectioneering JournalBy Matthew Bell, P.Eng. at IRISNDTIt can be challenging for failure analysts to present complex information to audiences that don't the same knowledge on specialized subjects. Sometimes, failure mechanisms can be summarized with images that can tell the whole story –...

March/April 2021 Inspectioneering JournalThis article will discuss a statistical analysis method that was developed to evaluate the integrity of pipelines that can identify, in a first phase inspection, whether the nature of the active damage mechanism(s) are uniform (general) or localized.
-
March/April 2021 Inspectioneering JournalBy Danny Landry at Premium Inspection & Testing GroupAs more are educated on the benefits of utilizing ropes and drones, skepticism has become far less common, and we’re sure to see adoption grow in the coming years of both of these methods—and, perhaps, of this new hybrid approach to work as well.

September/October 2020 Inspectioneering JournalBy Luciano Narcisi at Stork AMT, and Robert Westerhuis at Stork AMTImplementing RBI as part of a Mechanical Integrity system at different sites is not a simple copy and paste project. Each case has its own characteristics and challenges. This article describes implementation in two vastly different facilities.

May/June 2020 Inspectioneering JournalBy Phillip E. Prueter at The Equity Engineering Group, Inc., Brian R. Macejko, P.E. at The Equity Engineering Group, Inc., and Seetha Ramudu Kummari, Ph.D., P.E. at The Equity Engineering Group, Inc.This article provides an overview of brittle fracture, details on several industry failures, and a summary of deficiencies and concerns with current published methods for screening susceptibility of equipment to potential brittle fracture failures.
-
March/April 2020 Inspectioneering JournalBy Ana Benz at IRISNDTField hardness tests can provide valuable information when evaluating piping and pressure vessel anomalies. This article summarizes laboratory examinations designed to gain a better understanding of UCI hardness test results taken in the field.
-
March/April 2020 Inspectioneering JournalBy Baher Elsheikh at SAFCOThis article presents a comprehensive integrity management program for catalyst tubes, including elements on monitoring, inspection, data analysis, remaining life assessment, and control of human factors.
-
March/April 2020 Inspectioneering JournalBy Muhammed Al-Lutfallah at Saudi Aramco, and Tamim O. Felemban at Saudi AramcoThis article reviews the effectiveness of AET for inspecting tank bottoms in two ways; namely, benchmarking regulations in different countries and comparing AET and MFLT results through a case study.

March/April 2020 Inspectioneering JournalBy Geoff Clarkson at UTComp, Inc.This article describes the construction of corrosion-resistant fiber reinforced polymer (FRP), commonly used for pressure vessels and piping in the chemical processing industry, and the practices used for inspecting corrosion-resistant barriers.
-
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.
