DNV’s Pipeline Integrity Solutions group has developed measures to help U.S. pipeline operators meet recent directives of the Pipeline & Hazardous Materials Safety Administration (PHMSA).

PHMSA has directed operators to verify records used for establishing maximum operating pressure (MOP) and maximum allowable operating pressure (MAOP). The directives come largely as a result of a significant natural gas pipeline failure in San Bruno, CA in 2010 and are based on recommendations of a post-accident report submitted by the U.S. National Transportation Safety Board (NTSB).

Go to the links above to find documents that profile the 4-step process we’ve developed to satisfy PHMSA’s directives. One is a white paper written for the International Pipeline Conference (IPC2012) to be held in Calgary in September, authored by DNV’s Andy Lutz and Dr. Tom Bubenik. The other is an article written for DNV’s Pipeline Update publication (Fall 2012), authored by Chris Pollard. The Pipeline Update article will also appear in the upcoming October issue of Pipeline and Gas Journal.

We hope you can extract some meaningful information from these documents. Questions concerning the subject matter can be directed to andy.lutz@dnv.com or chris.pollard@dnv.com .
