API enhances pipeline safety with two updated standards

The American Petroleum Institute (API) has released two revised liquid pipeline leak detection standards to improve operational integrity and advance operators’ mitigation capabilities.
Published together because they address similar issues, Recommend Practice (RP) 1130, Computational Pipeline Monitoring for Liquids, and RP 1175, Pipeline Leak Detection—Program Management, are second edition standards designed to improve leak detection capabilities.
RP 1175 provides guidance for pipeline operators to create effective leak detection programs (LDP), with the aim of identifying leaks quickly and with certainty, facilitating a rapid shutdown and minimising negative consequences in the event of an incident.
RP 1130 addresses Computational Pipeline Monitoring (CPM), or algorithmic monitoring tools used to enhance the ability of a pipeline controller to recognise hydraulic anomalies that could show a pipeline leak.
Federal regulators, including the Pipeline and Hazardous Materials Safety Administration (PHMSA), have recently put renewed focused on leak detection for natural gas and liquid pipelines.
“Leak detection in liquid pipelines enables operators to quickly respond to incidents, minimising any impact on local communities and the environment,” said Anchal Liddar, senior vice president of API’s Global Industry Services.
“RPs 1130 and 1175 both play an important role in providing pipeline operators with critical guidelines to support early and accurate leak detection.”
