Fracture Mechanics and Pipeline Flaw Assessment
September 13-14
| Course schedule | |
| Day 1-2: | 8am-5pm |
Cracks, dents, wall loss and other anomalies pose a significant risk to pipeline integrity. This course will arm attendees with both the knowledge and the tools necessary to apply the latest technology to these serious threats. The focus is on the practical application of modern fracture mechanics and flaw assessment methods and models to pipeline integrity. All attendees will receive a suite of Excel-based tools for metal-loss assessment, burst-pressure prediction, rainflow cycle counting, and pressure cycle fatigue analysis. A workshop format will allow attendees to use this suite of tools on a series of practical problems – case studies will be presented and worked in order to apply the learnings and tools directly to attendees’ pipeline integrity programs.
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 receive1.4 CEUs.
Lecturers
Dr. Ted Anderson is an internationally recognized expert in fracture mechanics with 35 years of experience as a consultant for the oil and gas industry. He is the author of a best-selling book on fracture mechanics, which has been adopted as a required text in over 150 universities. He recently returned to independent consulting after serving as Senior VP of Technology Development for Team Inc. and the Chief Technology Officer for Quest Integrity. He founded a consulting and software company in 1995, which was acquired by Quest Integrity in 2007. He holds a Ph.D. in Metallurgy from the Colorado School of Mines.
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.
