Inline Inspection Technologies for Unique Applications
Speakers: Jeff Janvier, Pacific Gas and Electric Company
Greyson Brenk, Questar Gas
Tod Barker, T.D. Williamson, Inc.
Paul Laursen, Pipetel Technologies Inc.
Stefan Vages, ROSEN
How do you in-line inspect a difficult to pig pipeline? A panel of Operators and ILI vendors come together for a roundtable discussion of case studies and tool technology to address assessment of low-flow and low pressure lines, pipelines in casing, long seam defects and dual diameter pipelines. A joint session for the Natural Gas Transmission and the Pipeline Safety and Integrity Management tracks will encourage discussion of solutions to ILI assessment challenges.
Managing the Risk of Interactive Threats
Speakers: Gerry Bong, Pacific Gas and Electric Company
Ryan Lindblom, Pacific Gas and Electric Company
On January 27, 2015, the NTSB issued its report, “Safety Study, Integrity Management of Gas Transmission Pipelines in High Consequence Areas.” The NTSB made a recommendation to several agencies, including PHMSA, AGA and INGAA, to develop “expanded and improved guidance for operators and inspectors for consideration of interactive threats, among other recommendations.” This session will demonstrate approaches being used for inclusion of interactive threats in risk modeling and provide an opportunity for participants to discuss the topic further with peers.
Pipeline Safety Legislation and Regulatory Update
Speaker: Tom Finch, PHMSA
As a result of the Pipeline Safety, Regulatory Certainty and Job Creation Act of 2011 and post-incident NTSB recommendations, there has been substantial activity on pipeline safety regulations. This session will provide participants with important updates to recent final regulatory changes and proposed rulemaking.
Mitigation of AC Interference on Pipelines
Speakers: Shane Finneran, DNV GL
Michael Longpre, ATCO Gas
Bryon Winget, Pacific Gas and Electric Company
AC Interference is a natural phenomenon that, if left unchecked, may result in a multitude of operational and integrity concerns to pipeline operators. Careful consideration of the variables involved can significantly decrease the personnel, pipeline integrity and economic risks associated with mitigating the effects of AC Interference. This presentation examines the fundamentals of AC Interference, available mitigation techniques and explores options to move forward.
