Pipeline Pipeline Defect Assessment Workshop
Applied assessment methods & calculations

February 6
  7:30am Registration & coffee
  8:00am-5:00pm Course
February 7
  8:00am-4:45pm Course

This course is a follow-on to the famous Defect Assessment in Pipelines course taught by Dr Phil Hopkins and his colleagues at Penspen Integrity. It takes those who want to apply all the methods covered in Defect Assessment in Pipelines to the next level; it goes into greater depth on the various defect assessment methodologies and provides participants with hands-on practical experience performing calculations based on them. Cases and problems worked in class will be based on actual inspections of working pipeline systems. The course addresses both traditional pipeline methodologies as well as recent innovations, including the API 579 Fitness-for-Service Standard.

Documentation and materials


Who should attend

All presentation material will be documented in hard-copy in ring-binder format along with a digital copy on CD in Adobe Acrobat format. In addition participants will receive macro-enabled Excel spreadsheets that perform various calculations, including effective area metal loss assessment and pressure-cycle fatigue analysis. Attendees will also receive a copy of Fracture Mechanics: Fundamentals and Applications, 3rd Ed. by T.L. Anderson (a $110 value).

  • Pipeline engineers
  • Designers and service professionals who are involved with the maintenance, inspection, and repair of pipelines.

Continuing Education Units

  Upon completion of the course, participants will be eligible to receive 1.4 Continuing Education Units (CEUs).


Ian Smith is a consulting engineer with over 20 years in the pipeline industry. He formed his own consulting company in 2016 after having leadership roles within inline inspection, pipeline operating, and Fitness-for-Service consulting organizations. This has provided Ian with a unique perspective on the complete process of pipeline integrity from data collection to defect Fitness-for-Service assessment through to integrating assessment results into integrity management programs. He is a Professional Engineer and a member of ASME.
