Managing Cracking and Dents in Pipelines
Led by Sergio Limón
December 6-7, 2018: Calgary
Newly expanded to cover evaluation of Dent Fatigue Behavior
|Day 1:||8am - noon
1pm - 5pm
|Day 2:||8am - noon
1pm - 5pm
Various forms of cracks, crack-like indications and long seam weld anomalies are known to be present in pipelines, which can become a safety concern over the operational life of the pipeline. The most typical forms of cracking are manufacturing-related (such as lack of fusion, cold welds and hook-crack-like phenomena), operations-Driven (fatigue cracks initiating at imperfections or dents) and environmentally-assisted (stress corrosion cracking, hydrogen-induced cracking and corrosion fatigue cracking).
This course will cover in greater depth the formation and conditions that drive growth of cracks until they become unstable, leading to leaks or ruptures. The appropriate assessment methods such as ILI tools, pressure testing and direct assessments will be reviewed as well as traditional and current engineering methods for determining crack severity for response and remediation. Each attendee will receive a complimentary Excel-based crack assessment calculator which will be demonstrated in class using practical case studies.
It will be necessary to bring a laptop to this course.
On completion of the course, the student will understand what factors contribute to the formation and growth of crack‐like features and seam-weld anomalies on pipelines. In addition, participants will be able to gather and analyze the type and extent of cracking found, key operational parameters, pipe material properties, full-scale testing data, and ILI crack tool data, and to apply industry-recognized engineering methods for developing and recommending appropriate remedial action.
Participants will receive a full set of course slides and notes in print and electronic form, in color throughout, as well as an Excel-based tool for calculating failure pressure due to the presence of cracks.
Sergio Limón has worked in the oil & gas pipeline industry for more than 15 years with emphasis on pipeline integrity threat analysis and response. He was employed for 10 years with a large owner and operator of natural gas gathering, processing and transportation services. He led for six years the Asset Integrity group for the western division responsible for the analysis, response and remediation of integrity threats as well as the implementation of the Gas Integrity Management Program. Sergio holds B Sc. and M Sc. degrees in Mechanical Engineering with emphasis in fracture mechanics and materials from the University of Utah. He is the founder of Elevara Partners.
On completion of the course, participants will be awarded 1.4 CEUs.
