API RP 1188 - Hazardous Liquid Pipeline Facilities Integrity Management

Explore this topic

API RP 1188, Hazardous Liquid Pipeline Facilities Integrity Management, is a recommended practice developed and published by the American Petroleum Institute (API) that provides a framework for pipeline operators to develop a comprehensive pipeline facility integrity management program to strengthen efficiencies, prevent incidents and further reduce greenhouse gas emissions. The first edition of this recommended practice was published January 2022.

API RP 1188 covers the integrity management of all pressure-containing components directly used in the transport or storage of hazardous liquids within a liquids pipeline facility and is applicable to pipeline operators and integrity management inspectors. Hazardous liquids include, but are not limited to, crude oil, highly volatile liquids, gasoline, diesel, biofuels, lubricating oils, jet fuel, and aviation fuel. This recommended practice provides specific guidance on:

  • high-consequence area impact determinations;
  • data integration;
  • threat identification;
  • risk assessment;
  • inspection and reinspection;
  • preventive and mitigative measures;
  • performance measures.

API RP 1188 outlines a plan-do-check-act cycle to carry out continuous assessment and improvement for a pipeline facility integrity program. Applicable facilities include terminal and pipeline station piping systems within terminal and pipeline facility boundaries. RP 1188 also applies to off-plot piping, which includes, but is not limited to, piping between facilities, piping that comes from or goes to a refinery or other type facility, or piping that may cross a road, ditch, or other property outside the confines of a terminal facility. This recommended practice does not apply to refinery piping, sanitary waste piping, cast iron piping, or nonmetallic gravity flow piping systems. 

API RP 1188 builds on concepts developed in API RP 1160, Managing System Integrity for Hazardous Liquid Pipelines. Additional guidance is available in documents such as API 570, Piping Inspection Code: In-Service Inspection, Repair, and Alteration of Piping Systems, and API Std 2610, Design, Construction, Operation, Maintenance, and Inspection of Terminal and Tank Facilities.
