Gary Smith is president of Inline
Services, a Houston-based company specializing in pigging
equipment and services. He has 27 years experience in
the pipeline pigging industry, working in services such
as commissioning and maintenance of pipelines as well
as with designing and manufacturing pigging equipment.
Dr. Martin Phillips is a Senior Engineer with CC Technologies Services, Inc. He has more than 20 years experience with ILI and
pipeline integrity services, including management of multi-pipeline
inspection programs using different ILI tools and development of ILI
tools for metal loss and cracking.
George Williamson has over 22 years of Operations, maintenance and Integrity Management experience. He is a registered professional engineer, NACE certified corrosion and cathodic protection specialist, and certified pipeline integrity specialist.
Pipeline Repair Methods/Inservice Welding
Bill Bruce is director of welding technology with DNV Columbus (formerly CC Technologies). Prior to joining CCT, he was a technology leader at Edison Welding Institute and a senior engineer at Panhandle Eastern Pipeline Co. He is a member of the American Petroleum Institute API 1104 Committee and is the chairman of the Maintenance Welding Subcommittee.
Dr. Chris Alexander is a Principal at Stress Engineering Services, Inc. In
terms of pipeline work, He has been integrally involved in assessing the
effects of dents and mechanical damage on the structural integrity of
pipelines. These efforts have involved full-scale burst and cyclic
pressure fatigue testing, as well as modeling dents using finite element
analysis. Dr. Alexander has also been involved in assessing the use of
composites in repairing pipelines and offshore risers. He has published
more than 50 technical papers and has made international presentations
on a wide range of topics.
He has received B.S. M.S., and Ph.D. degrees in Mechanical Engineering
from Texas A&M University.
Stress Corrosion Cracking in Pipelines
Dr. Raymond R. Fessler worked on the Pipeline Research Committee project on SCC since its inception in 1965. He personally conducted most of the early field investigations of SCC, from which he identified the major factors that cause high-pH SCC in pipelines. He also managed the laboratory portion of that program from 1965 to 1982, which added significantly to an understanding of the phenomenon and explored a number of possible solutions to the problem. For the past several years, he has been the SCC consultant for GRI and PRCI. He recently completed a comprehensive gap analysis on SCC, and he actively participated in drafting the NACE Recommended Practice on SCC Direct Assessment.
John Mackenzie is a senior pipeline specialist with Kiefner & Associates, focusing on the areas of Integrity Management Plans and Stress Corrosion Cracking. John was previously with TransCanada Pipelines for 25 years, where he was responsible for the company’s original investigation into SCC (1986-1990). This work led to the discovery of near-neutral pH SCC and identified the conditions under which it occurs. He also served as Chair of the PRCI’s SCC Subcommittee for two years.
