Pipeline Things

Canada may be just across the border, but when it comes to pipeline integrity management, the differences can make it feel like we’re oceans apart. Learn how each country balances the world of politics and regulators, the key differences in engineering approaches, and the distinction between performance versus prescriptive culture.

In this episode of Pipeline Things, Rhett and Chris bring on Dr. Nicki Robertson, who is currently standing up D2 Integrity’s Canadian office, to discuss pipeline regulations across borders.

Highlights:

Key differences and similarities between each country’s regulatory environment

How each country approaches interpreting regulations

Relationships between operators and regulators

Ensuring sound engineering for engineering assessments

On this episode of the Pipeline Things podcast, Rhett and Christopher sit down with guest Mark Ryan of Phillips 66 to discuss the impact of Part Three of the PHMSA Mega Rule on onshore gas gathering lines, 8-inch and up. The discussion confronts the reality that with its adoption, there are no longer any unregulated gas lines.

Highlights:

Motivations behind the rule stem from a wide-scale effort to reduce emissions across the pipeline industry.

Enhanced compliance thresholds for gas gathering lines have introduced challenges and opportunities for pipeline operators, like new classifications and reporting requirements.

Implications of prescriptive vs. performance-based integrity management as the gas gathering space continues to evolve.

If you haven’t thought of the impact of the Mega Rule on gathering lines before, or if you’re knee deep in the new regulations, this episode is for you.

Excavating an anomaly flagged during an in-line inspection can sometimes feel like opening a box of chocolates. Say it with us, now: “You never know what you’re going to get.”  

When determining whether a composite system is a suitable repair option, defining permanency (i.e., What does permanent mean to you?), evaluating the long-term strength of the system, and understanding the role of adhesion all come into play.  

In this episode of Pipeline Things, Rhett and Chris sit down with special guest Tim Mally to discuss the ins and outs of using composites, common installation issues, and some of the major challenges with composite repairs.  

Highlights: 

Essential variables considered when evaluating composite repair applicability 

The importance of surface prep and proper adhesion for a successful composite repair  

Exploring the heightened scrutiny of composite repairs compared to alternative methods 

Common questions with ensuring “permanency” of composite repairs

There’s a lot to learn about MFL tools, and who better to learn it from than the one and only Bruce Nestleroth.

In this episode of Pipeline Things, Rhett and Chris sit down with returning special guest Bruce Nestleroth, as they dive headfirst into a heavily debated topics around MFL technology. It’s a conversation filled with details of MFL capabilities and advancements in recent years, how it has refined, and where future opportunities might lie.

Highlights:

What “high resolution” really means for MFL tools

MFL data, RSTRENG, and P-Square approaches for burst pressure predictions

Capabilities for capturing true “river bottom” profiles for corrosion

The questions operators should ask their MFL vendors
