Pipeline Repair Methods, Hot Tapping, and
In-Service Welding
Led by Bill Bruce and Dr. Chris Alexander

The objective of this two-day course is to provide an in-depth overview of the various aspects of pipeline repair and modification (full-encirclement sleeves, hot taps, etc.) as well as to address the concerns for welding onto in-service pipelines. A thorough understanding of the factors that affect the concerns for welding onto in-service pipelines will allow repairs and modifications to be made with confidence. The proper use of in-service welding allows both economic and environmental benefits to be realized by avoiding pipeline shutdown and interruption of service. The course is intended for a wide range of personnel - from engineers and managers to welders and inspectors.
Pipeline engineers, Operations and Maintenance personnel, inspectors, and welders.
All delegates will receive a detailed set of lecture notes containing more than 250 pages, providing an invaluable reference document after the course.
Upon completion of the course, participants will be eligible to receive1.4 CEUs.
Dr. Chris Alexander is the president of ADV Integrity, 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.

The course takes place over two full days and will dispel a number of misconceptions that have developed pertaining to operating practices required to safely weld onto an in-service pipeline. If the knowledge gained can be used to justify the application of in-service welding where it would have otherwise been prohibited (or prevent a single failure), the first application of the results can often offset the cost of attendance by orders of magnitude. The application of industry best practices for pipeline repair, hot tapping, and in-service welding will ensure the safety of workers, reduce the probability of a failure, and can help to extend the life of pipeline systems.
