New methodology based on structural mechanics and probability theory helps pipeline operators assess and ensure the integrity of their onshore high-pressure pipelines. This field-proven approach called SRA (structural reliability analysis), goes beyond fit-for-purpose assessment. It uses the concept of Bayesian Updating to handle the uncertainties inherent in managing thousands of miles of underground pipelines as it quantifies the contribution of each safety measure to the prevention of failure. The operator then sets an integrity level based on consideration of likely threats and consequences of failure. Using SRA, operators can achieve and show consistent levels of reliability and safety, even for non-piggable pipelines. Moreover, by effectively allocating resources to control the risk on their systems, operators can ultimately reduce the cost of their total integrity-management program.
