Shamus McDonnell

Shamus McDonnell


As president of PureHM since March 1995, as well as leader of the Pipeline Integrity Services Division, Shamus’ responsibility for pipeline integrity services includes data collection, correlation and validation through excavation for a variety of pipeline integrity inspections surveys including leak, depth of cover, cathodic protection, inline inspection, coating condition and GPS. With over 25-years of hands-on experience, Shamus has contributed to technological advancements in the North American pipeline industry. He continues to play an integral role in the business management at PureHM as well as overall coordination of projects involving pipeline integrity consulting, pipeline pigging, ECDA surveys, technology research, and development.

Jim Hunter

Jim Hunter

Vice President of Operations

With over 30-years in the pipeline inspection business, Jim’s experience and expertise are valuable tools in his role of VP Operations. Jim started out as a welder in the late 70s in Western Canada’s booming oilfields. The noise, smoke, and constant flashes grew old quickly though, and Jim agreed that disco did, indeed, suck. In 1986 Jim joined Tuboscope’s Linalog division in Nisku, Alberta and began his career in Pipeline inspection. By 1995 he had found the right partners in Shamus and Cari McDonnell and along with his wife Juanita they launched Hunter McDonnell Pipeline Services Inc. Good service, constant innovation and crazy hours helped turn the little Ma and Pa into a corporation that lead the way and turned heads into the new millennium. Jim maintained a role of operations manager pretty much from the outset and leaned on his pig tracking experience as the company grew. In his role at PureHM Jim continues to emphasize the commitment to customer satisfaction, to safety, and to project quality that has made this company a true leader in its field.
