API RP 1160 - Managing System Integrity for Hazardous Liquid Pipelines

Explore this topic

API RP 1160, Managing System Integrity for Hazardous Liquid Pipelines, is a recommended practice developed and published by the American Petroleum Institute (API) that provides a process for establishing safe operations of hazardous liquid pipelines, including robust assessments of potential risks and the establishment of systems to safely and sustainably manage them throughout day-to-day operations. This recommended practice was originally published in 2001, and the most recent 3rd Edition was released in February of 2019.

API RP 1160 is specifically designed to provide pipeline operators with descriptions of industry-proven practices in pipeline integrity management. An effective pipeline integrity management program provides a way to improve the safety of pipeline systems and to allocate operator resources effectively to:

  • identify and analyze actual and potential precursor events that can result in pipeline incidents; 
  • examine the likelihood and potential severity of pipeline incidents; 
  • provide a comprehensive and integrated method for examining and comparing the spectrum of risks and risk reduction activities available; 
  • provide a structured, easily-communicated way for selecting and implementing risk reduction activities; 
  • establish and track system performance with the goal of improving that performance.

API RP 1160 is intended to cover, but is not limited to, pipeline systems used to transport hazardous liquids, such as crude oil, highly volatile liquids, gasoline, diesel, biofuels, lubricating oils, jet fuel, and aviation fuel. It is largely targeted at onshore pipelines along the right-of-way, but the process and approach can be applied to pipeline facilities, including pipeline stations, terminals, and delivery facilities associated with pipeline systems. This recommended practice is designed for use by individuals and teams charged with planning, implementing, and improving a pipeline integrity management program. A team may include engineers, operating personnel, and technicians or specialists with specific experience or expertise in things like inspection, metallurgy, corrosion, and risk mitigation.
