We're sorry, but all tickets sales have ended because the event is expired.

David Norfleet, Greg Morris, Greg Quickel, and Kathy Buckingham will present, “Pipeline Failure Investigation and Root Cause Analysis” on September 23, 2021.

This training has the minimum required to hold the class. Further information to be provided upon registration.


Unexpected events occur in all industries with designed and maintained assets. The pipeline industry is no different.  These events, such as releases and ruptures, provide an opportunity to collect data and learn from the event such that future events can be mitigated.  In addition, large events often result in interest from media, regulators, and external parties that may bring lawsuits against the operator and subcontractors responsible for constructing, operating, and maintaining the asset.  The steps taken following an event are time-sensitive and critical.

The workshop will discuss the three primary phases in an investigation: On-site Examination, Metallurgical /Materials Failure Analysis, and Root Cause Analysis.  The processes and applicable steps pertaining to each phase will be discussed, with case studies and discussion on what to do and what not to do to maintain the integrity of the investigation.

What does an Incident Investigation involve?

Why do we perform Incident Investigations?

Who should perform Each Step of an Incident Investigation?

On-site Examination

  • What samples do I need to collect?
  • How do I know if I found the failure origin?
  • A fire occurred as a result of the failure. Does this impact my samples?
  • Is there anything I should not do?
  • Are there tests that need to be performed in the field?
  • How should I handle/preserve samples?
  • How should I label samples?
  • How should I ship samples?

Metallurgical / Materials Failure Analysis

  • Steps of the Failure Analysis
  • Visual Examination
  • Chemical and Microbiological Analyses of Deposits
  • Non-destructive Testing
  • Fractography
  • Metallography
  • Mechanical Testing
  • Testing of Metallic vs. Non-metallic Samples

Root Cause Analysis

  • Purpose
  • Root Cause definition
  • Evidence Capture
    • Interviews
    • Documentation
  • Timeline Generation
  • Hypothesis Development
  • Select and Apply the Appropriate Methodology for the RCA
  • Reporting and Recommendations

Greg Quickel

Mr. Quickel is Head of Section-Incident Investigation at DNV.  He has worked on over 100 failure analysis projects in the oil and gas, utilities, and aerospace industry.  Some of the causes of failure he has worked on include stress corrosion cracking (SCC), caustic cracking, oxygen corrosion, carbonic acid corrosion, microbially influenced corrosion (MIC), selective seam corrosion, various seam weld defect failures, hydrogen cracking of girth welds, fatigue, corrosion fatigue, creep, and mechanical damage.  Mr. Quickel is a Licensed Professional Engineer (P.E.) in the state of Ohio and graduated from The Ohio State University with a B.S and M.S. in Materials Science & Engineering.

Greg Morris

Mr. Morris is a Principal Engineer in the Incident Investigation section at DNV in Dublin, Ohio. He joined DNV in 2019 with 27 years’ experience in the pipeline industry.
Prior to joining DNV, Mr. Morris was employed by Kiefner & Associates where he was involved in integrity management support, failure investigation, risk assessment, material specifications and training.  Mr. Morris is an active member of API Subcommittee 5 that maintains API 5L and was a member of the Task Group of ASME Subcommittee F that developed the first edition of ASME B16.49 for induction bends.  His training experience includes; Instructor, Pipeline Reliability Assessment Workshop, a two-day technical course presented to pipeline operators and Federal and State regulators, courses on defect assessment and repair, and a two-day course on the ASME B31.4 Safety Code.
