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.
Onshore Pipeline Engineering
Professor Phil Hopkins has more than 26 years’ experience in pipeline engineering, and is Technical Director with Penspen Integrity and Visiting Professor of Engineering at the University of Newcastle-upon-Tyne. He has worked with most of the major oil and gas companies and pipeline companies around the world, providing consultancy on management, business, design, maintenance, inspection, risk analysis and safety, and failure investigations. He is the immediate past-chairman of the Executive Committee of the ASME Pipeline Systems Division and has served on many other professional committees, including the British Standards Institution, European Pipeline Research Group, the American Gas Association’s Pipeline Research Committee, and the DNV Pipeline Committee. More than 1700 engineers and technical personnel around the world have attended his Pipeline Defect Assessment and Pipeline Integrity-related courses.
Dr. Roger King has over 30 years’ experience of corrosion in the oil, gas, civil, and nuclear industries. Dr King ran the premier microbiological corrosion group at UMIST for seven years; the group accumulated over 150 man-years of research into corrosion by micro-organisms. The group published over 100 theses, dissertations and papers on bacterial corrosion and its prevention and treatment.
He also has specialist knowledge of sweet and sour corrosion and its prevention by chemical inhibition, monitoring of corrosion and the design of efficient cathodic-protection systems for flowlines, structures, and seabed installations. He has been an independent consultant since September, 1989, and prior to this was a founder member of the Corrosion and Protection Centre Industrial Service (CAPCIS) at the University of Manchester, UK.
Pipeline Repair Methods / In-Service Welding
Bill Bruce is director of welding technology with 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.
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.
Excavation Inspection, ILI and DA Correlation
Jim Marr is currently technical integrity specialist with Baker Hughes Pipeline Management Group. He is also president of the pipeline consulting firm Marr Associates. He founded the original company in 1992 and was its president until late December 2002. In 2006, with the reforming of Marr Associates, two additional companies were developed to maintain Marr Associates’ tradition of providing comprehensive pipeline integrity field services such as modeling, direct examination, and project management. Jim has worked in pipeline integrity for the past 20 years, focusing on SCC, external corrosion, direct assessment, direct examination, ILI development and correlation, data management, and the characterization of the environment around the pipe. He has published numerous papers related to SCC, investigative procedures, and environmental relationships related to time-dependent pipeline threats. He graduated with a degree in earth sciences in 1986 from the University of Guelph, Ontario. He is a member of NACE and a past vice-chair of the NACE SCCDA committee.
James Pennie is an advanced NDT consultant with Eclipse Scientific Inc. With offices in Waterloo, Ontario and Edmonton, Alberta, Eclipse Scientific develops specialized products and techniques for the NDT industry, specifically in the advanced ultrasonic (UT) discipline. James has been in the Non Destructive Testing industry for 10 years, and has spent that time working within pipeline integrity field, with his initial involvement working with Marr Associates. While at Marr Associates as a project manager, James was responsible for field activities which included SCCDA, ECDA, ICDA, and ILI correlation programs. James now provides Advanced UT Expertise to clients worldwide, to assist with implementation of new technologies, training of personnel, and procedure and technique development for both the onshore and offshore industry.
Optimizing Reliability of ILI Inspections
Guy Desjardins is president of Desjardins Integrity, a consulting firm in Calgary, AB. He has more than 25 years experience in the oil and gas industry and 12 years with pipelines. In 1997, he became a principal co-owner of Morrison Scientific and became Morrison’s president in 1998. He has been an independent consultant since 2005, offering services of data analysis, research, and software development.
