The American Petroleum Institute (API) initiated this project through Pipeline Research Council International, Inc. (PRCI), to apprise industry consensus recommended practices regarding reasonable and prudent crack in-line inspection (ILI) response criteria for hazardous liquid pipelines based on a comprehensive and informed consideration of current practices, processes, research, ILI performance and the industry’s operating history. API Recommended Practice (RP) 1176, Assessment and Management of Cracking in Pipelines, are currently being prepared. A target date for a notice...
The American Petroleum Institute (API) initiated this project through Pipeline Research Council International, Inc. (PRCI), to apprise industry consensus recommended practices regarding reasonable and prudent crack in-line inspection (ILI) response criteria for hazardous liquid pipelines based on a comprehensive and informed consideration of current practices, processes, research, ILI performance and the industry’s operating history. API Recommended Practice (RP) 1176, Assessment and Management of Cracking in Pipelines, are currently being prepared. A target date for a notice of proposed rulemaking (NPRM) from the U.S. Department of Transportation’s (DOT) Pipeline and Hazardous Material Safety Administration (PHMSA) for Title 49 Code of Federal Regulation (CFR) §195.452 has not been communicated at this time, however it is anticipated by the industry that an NPRM addressing changes to pipeline integrity management is forthcoming. The objective of this research is to substantiate API’s stated depth and failure pressure ratio (FPR) response criteria applicable to ILI reported cracking anomalies in hazardous liquid pipelines, as well as facilitate operator and regulator technical insight sharing.
