• What Makes an Effective Composite Repair & That Thing They Say About Boxes of Chocolate, with Tim Mally

  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  Connect:     Rhett Dotson     Christopher De Leon     Tim Mally  D2 Integrity     Be sure to subscribe and leave a comment or rating!     Pipeline Things is presented by D2 Integrity and produced by FORME Marketing.      D2 Integrity (D2I) is providing this podcast as an educational resource, but it is neither a legal interpretation nor a statement of D2I policy.

• Failure Files 2.0: Geohazards

  On this episode of the Failure Files series, Pipeline Things break down a significant geohazard incident: the 2023 rupture of Gulf South’s Index 381 pipeline near Jackson, Mississippi. Rhett and Christopher unpack how a vintage weld flaw, masked geohazards, and the limitations of in-line inspection (ILI) tools came together to produce a high-cost failure. This episode is a must-listen for anyone working in integrity management or considering how to implement effective geohazard management programs. Highlights: How a Mississippi pipeline was impacted by construction work on a reactivated retention pond The slow-moving, well-documented earth movement that still went unaddressed A girth weld defect from 1952 and why ILI didn’t catch it in time Why LiDAR and bending strain data weren’t enough without expert interpretation   Connect:    Rhett Dotson    Christopher De Leon    D2 Integrity    Be sure to subscribe and leave a comment or rating!    Pipeline Things is presented by D2 Integrity and produced by FORME Marketing.     D2 Integrity (D2I) is providing this podcast as an educational resource, but it is neither a legal interpretation nor a statement of D2I policy.

• Failure Files 2.0: Third Party Damage

  In this episode of the Failure Files series, Pipeline Things tackles one of the most persistent and arguably preventable causes of pipeline failure in North America: third-party damage. Rhett and Christopher walk through four real-world incidents, ranging from farmland to construction sites, where pipelines were struck. In some of these cases, lives were lost, all because no one called 811, or location information was ignored. From Brandon, MN to Dixon, IL, these stories reveal a pattern of missed warning signs, incomplete communication, and public awareness efforts that failed to translate into action. This episode breaks down the responsibility on both sides of the fence and how even well-intentioned outreach can fall short without boots-on-the-ground follow-through. Highlights: Why do over 160,000 third-party damages still happen each year, despite widespread awareness campaigns? A bulldozer strike in Georgia that turned deadly for a contractor’s family The repeat offender: a pipeline in Kansas hit multiple times by the same excavation crew How Kinder Morgan’s years of landowner outreach still couldn’t prevent a fatal accident What does DIRT data tell us about who’s not calling 811, and why? The limitations of signs, mailers, and brochures when human behavior doesn’t change What can pipeline professionals do to prevent future third party damage incidents? “Three Seconds Later” (Dixon Incident Video): https://youtu.be/Ejxvrnfk2uE   Connect:    Rhett Dotson    Christopher De Leon    D2 Integrity    Be sure to subscribe and leave a comment or rating!    Pipeline Things is presented by D2 Integrity and produced by FORME Marketing.     D2 Integrity (D2I) is providing this podcast as an educational resource, but it is neither a legal interpretation nor a statement of D2I policy.
