Pipeline Reliability

Pipeline Cracking Reliability and Assessment Seminar


Although the tools to manage the threats to pipelines caused by corrosion metal loss are well understood, the tools used for cracking are not as well developed. This session is intended to provide training for pipeline personnel who must deal with threats to pipeline safety caused by cracking. The material presented provides a introduction to the techniques for dealing with pipeline cracking and compares the methods to those used for managing corrosion.


The session is given by Mr. Dennis Johnston and Mr. Harvey Haines.

Mr. Johnson is a Senior Pipeline Specialist at Kiefner and Associates, Inc.

Mr. Johnson’s nearly 30-year career in the pipeline industry has involved internal inspection, general pipeline maintenance, welding procedures and testing, new pipe inspection, existing pipe inspection, nondestructive testing, and flaw evaluation. Mr. Johnston has served on committees for PRCI and API. Formerly with Colonial Pipeline Company, Mr. Johnston developed methods to detect small indentations that were determined to be third-party damage on large-diameter liquid pipelines.

Mr. Haines is a Senior Pipeline Specialist at Kiefner and Associates, Inc and manages pipeline integrity projects.

Mr. Haines’ 28-year career in the oil and gas industry includes the development and use of NDE techniques for pipelines and oil and gas wells. One of his current topics of interest is understanding ILI measurement error and how it affects corrosion assessment using B31G and RSTRENG.


The workshop can be presented periodically for pipeline operator personnel at their facilities who face crack assessment issues on a daily basis. The workshop is held for 1 ½ days. Each participant is provided with a course notebook containing copies of the slides and viewgraphs, and professional development hours are given for attending the workshop (certificate provided).
