The document provides a comprehensive analysis of integrity hazard classification for spooled composite pipelines, detailing the performance, failures, and management strategies for over 10,476 licensed pipelines in Alberta. It highlights critical failure mechanisms linked to operational practices, such as excessive axial forces during slug flow and water hammer events, which account for the majority of pipeline failures. The document also proposes an integrity management strategy based on a triage model that effectively mitigates risks associated with pipeline failures.
