This paper presents the first field deployment of the gPIMS guided wave corrosion monitoring system by Gascade as part of a strategic initiative to maintain the integrity of existing natural gas pipeline infrastructure as it repurposed for hydrogen transport. The gPIMS system is a permanently installed, non-intrusive monitoring solution that uses guided ultrasonic waves to detect and track corrosion in pipelines over extended distances, offering an effective alternative to conventional inspection methods in challenging or inaccessible environments.
The paper focuses on the practical aspects of its implementation for continuous monitoring of pipelines embedded within sleeved road-crossings, including site preparation, system commissioning, automated data collection, and upload into a cloud-based data management platform. Initial field results are presented, highlighting the sensitivity and reliability of the technology in detecting corrosion and tracking changes over time. Capabilities and limitations of gPIMS are discussed, offering insights into its potential role in long-term asset monitoring strategies.
