Pipeline Defect Assessments for CSA Z662 Pipelines

Pipeline regulations in Canada differ from the ASME B31.4 and B31.8 standards used across the United States. In this article, the authors provide a detailed overview of the federally regulated CSA Z662 standard and clarify the differences between assessments (Section 10), engineering assessments (Section 3.4), and engineering critical assessments (Annex J & K). This is a must- read for any pipeline operators who wants to understand Canadian pipeline industry regulation and engineering assessment requirements.

Damage Review and Risk Assessment of Midstream Amine Processing Units

For those who had the opportunity to watch last week’s webinar presented by Brian and Shane, this article expands on the benefits of risk-based inspection (RBI) for amine processing units and offers a multidisciplinary approach. It begins with an overview of the process and rich/lean amine loading, identifies key damage mechanisms and areas of concern, and proposes options for corrosion mitigation.

Are Dents Really a Problem?

There are several assessment procedures available for evaluating dents and determining whether a dent poses a viable threat to the integrity of a component. Read about common analysis methods for the critical failure mechanisms, potential failure mechanisms such as creep, complex dent configurations, and highlight the value of using a Level 3 finite element analysis (FEA) to determine whether the dent is truly a problem.

How Playing Battleship Helps with CML Optimization

How Playing Battleship Helps with CML Optimization

As a child, many of us played the game Battleship. But did you know this game provides a great introduction to Bayesian updating and corrosion monitoring location (CML) optimization? Using the Battleship analogy, Branden Stucky introduces the Bayesian Optimized Asset Reliability (BOAR) assessment and provides insight into how to combine expert knowledge with collected data to identify corrosion rates.
