Pipeline Safety

The United States Department of Transportation (USDOT), Pipeline and Hazardous Materials Safety Administration (PHMSA), Office of Pipeline Safety recognizes there may be technologies and advancements not currently allowed by the federal regulations that can improve safety, and has processes to allow such technologies and advancements. These processes include Special Permits, State Waivers, and Other Technology Notifications. This paper describes observations and trends related to PHMSA’s accumulated data from the last few decades, and includes a summary of new technologies and innovative solutions that are not currently covered in codified standards or regulations.1

Since the 1970s, the United States Department of Transportation (USDOT) Pipeline and Hazardous Materials Safety Administration (PHMSA) has collected and published pipeline failure incident data. Operators are required to report pipeline incidents and provide the apparent cause of failures. PHMSA and ASME (B31.8S for gas and B31.4 for liquids) identify and group these failures into nine broad categories and sub-classify them into three clusters by their time-based behavior. Technical advancements in pipe manufacturing, fabrication, construction, operation, inspection, monitoring, maintenance, rehabilitation and regulation have resulted in a decrease in incidents for many of these failure causes. This paper presents a statistical trending analysis of the failure incidents for each of the nine threats. The multi-year trending of these incident metrics over the last 40+ years will be demonstrated.

Pipeline Safety

Recent pipeline accidents in the United States have highlighted concerns with older vintage natural gas and hazardous liquid pipelines. The United States Department of Transportation (USDOT) Pipeline and Hazardous Materials Safety Administration (PHMSA) is performing a comprehensive review to determine the fitness for service of vintage pipelines, and if the risks associated with vintage pipelines can be better managed by changes to US pipeline safety standards and regulations. Concerns with vintage pipelines include weld seam manufacturing issues, such as low frequency electric resistance welding (LF-ERW) and submerged arc welding (SAW), cast iron pipe, plastic pipe and certain coatings. This paper presents findings from vintage pipeline failure investigations, recent PHMSA actions, and some approaches to address key vintage pipe concerns. These approaches include knowledge assurance (adequacy and quality of historical data), methods to systematically obtain missing data, and processes and criteria for determining fitness-for-service, including assessment, remediation, and replacement programs.
