Fracture Mechanics for Pipeline Engineers
Led by Dr. Ted Anderson
November 14-16, 2018: Houston

This course can be attended in-person or online

Course schedule
Day 1:  1pm - 5pm
Day 2:  8am - noon
1pm - 5pm
Day 3:  8am - noon

Cracks and other planar 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 this serious threat. 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 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.

A laptop is required for this course.

Documentation

  • An Excel-VBA application that performs burst pressure calculations, rainflow analysis, and pressure cycle fatigue analysis.

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.

Lecturer

Dr. Ted Anderson 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.
