Pipeline Defect Assessment Workshop
Led by Ian Smith
May 9-10, 2018, Houston


Participate online via our state-of-the-art video conferencing technology

Course schedule
Day 1-2:  8am-5pm

This course involves practical application of the principles and methods learned in our Defect Assessment in Pipelines course. It takes those who want to take their defect assessment knowledge 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. Participants will become comfortable performing and reviewing a wide variety of anomaly assessment methodologies and will understand when to best apply them within an Integrity Management Program. 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

All presentation material will be documented in an Adobe Acrobat PDF provided by download prior to the class. For this reason it is necessary to bring your laptop or tablet computer. In addition participants will receive macro-enabled Excel spreadsheets that perform various calculations, including effective area metal loss assessment and pressure-cycle fatigue analysis. A laptop is required.

Who should attend

  • 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 CEUs.


Ian Smith is a consulting engineer with over 20 years in the pipeline industry. He formed his own consulting company, ID Smith Pipeline Engineering, 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.
