Abstract: The author has worked on many milestone trenchless projects and processes throughout his extensive career, but this project stands out in particular - the planning, coordinating and completion of the largest diameter leaking high pressure gas main operating at 15 psig renewal using CIPL. This project was extremely challenging and a monumental accomplishment. With rapidly approaching cold weather on a major critical feed, this project taxed every bit of knowledge and practical experience the author has gained leading lining projects for the gas industry since the early 90s when lining technology first started being used by the gas industry. This project required meticulous planning and presented many challenges for the installation crew that will be detailed as the work progressed. Included will be a discussion on the solutions engineered during the course of the work due to unforseen circumstances that ultimately led to a successful project conclusion and lessons learned.
