Pipeline Safety: Stress Corrosion Cracking (SCC) Workshop

The Office of Pipeline Safety and the National Association of Pipeline Safety Representatives are cosponsoring a workshop on stress corrosion cracking (SCC) with the pipeline industry trade associations (API, AOPL, INGAA, AGA, and NACE International). The workshop will be held on Tuesday, December 2, 2003, from 8:00 a.m. to 5:00 p.m. at the Westin Oaks Hotel, 5011 Westheimer Blvd., Houston, TX 77056 (telephone: 713-960-8100; fax: 713-960-6553). To facilitate meeting planning, advance registration for this meeting is strongly encouraged and can be accomplished online at the following web site: primis.rspa.dot.gov/meetings. EDITOR’S NOTE: THERE WAS A TYPO IN THIS LINK IN THE OFFICIAL OPS NOTICE, WHICH PREVENTED IT FROM WORKING. THE LINK IN THIS NOTICE IS CORRECT.

RSPA/OPS recently issued an Advisory Bulletin to remind owners and operators of gas transmission and hazardous liquid pipelines to consider SCC as a risk factor when developing and implementing Integrity Management Plans. All owners and operators of pipeline systems, whether or not their pipeline systems are subject to the Integrity Management Plan rules, should determine whether their pipeline system is susceptible to SCC and assess the impact of SCC on pipeline integrity. Based on this evaluation an operator should prioritize application of internal inspection, hydrostatic testing, or other forms of integrity verification.

The workshop on December 2, 2003, will address the following topics:

  1. Stress Corrosion Cracking – description, science, and history
  2. Practical application of SCC principles – how to assess SCC in operating pipelines within the context of integrity management
  3. Response to the occurrence of SCC – guidelines for response and remediation; addressing public concerns
  4. Research and development – knowledge gaps and next steps

This is a technical workshop aimed at sharing information on SCC in pipelines among operators and technical experts, providing regulators with information they can use in pipeline inspection and oversight, and reviewing priorities for research to address the problems posed by SCC in operating gas and hazardous liquid pipelines.
