US Pipeline operators face increasing regulations that focus on the safety of their transmission systems. The Office of Pipeline Safety mandates the development of comprehensive integrity management programs from pipeline operators. The revised CFR 49 Part 195 became regulation following the signing of the Pipeline Safety Act of 2002. The legislation requires the implementation of comprehensive Integrity Management Programs, the conduct of baseline assessments and period reassessments to identify and evaluate potential threats to pipelines, remediate significant defects discovered during these processes; and continually monitor program effectiveness so that modifications can be recognized and implemented.
In Canada, the Canada National Energy Board (NEB) “On-Shore Pipeline Regulations” first enacted in 1999 also has requirements for the development of pipeline integrity management programs (IMP). IMPs are required to include a Records Management System (RMS), periodic condition monitoring, mitigation of defects identified.
Assessment methods typically include: internal inspection tools (including inline and pig testing), pressure tests, direct assessments, and other methods.
