Committee Structure

• Chair - Amy Livingston, Compliance Manager Kinder Morgan

• Vice Chair – Mike Burkhart, Program Manager Nicor Gas

• Secretary – Paul Stumpf, ASME

Committee Makeup

• 30 Voting Members• Representing:– Transmission pipeline companies (10)– Distribution companies (8)– Liquid pipeline companies (2)– State and Federal agencies (3)– Vendors (6)– ASME (1)

Member Locations

Committee Work 2012 - 2013

• Preparation for next release• Ad-hoc meetings• Committee meetings• Balloting Process

Preparation for Release

• Revise Task Guidance:– Several instances where the written guidance did

not match the intent of the task.

• Revise Task Language:– Each task rewritten to eliminate by inclusion the

main AOC’s that could be encountered (PHMSA)

– Additional language inserted to add clarity

Examples

Current• Identify requirements• Perform task equipment check• Test/troubleshoot rectifier• Repair or replace defective

rectifier components• Place in service• Adjust output• Recognize and react to AOC’s• If required, complete

documentation

New• Select task procedure(s)

and appropriate equipment• Perform test equipment

check to verify that equipment functions within specified parameters – Inspect equipment– Verify equipment is calibrated– Test equipment

ContinuedTest rectifier and troubleshoot problems•Monitor requirements of all impressed current sources•Visually inspect components of the rectifier•Check electrical connections (anode, ground beds, power supply, structure, electrical ground, etc.)•Identify and locate correct test points•Connect instruments and test leads to correct locations•Operate test equipment and take readings

– Rectifier voltage and current output to include current drains, shunt using a high impedance voltmeter, ammeter (direct or indirect), and shunt, if applicable

– Watt-hour reading, if applicable– Internally mounted voltage and amperage meter

•Analyze and interpret test results– Maximum rated outputs

•Common component failures and output indications

ContinuedRepair or replace defective rectifier components as applicable•AC/DC circuit breakers•Power connection/safety ground•Fuses•Diodes•Disconnects•Rectifying elements•Transformer•Lightening arrestors•Shunts•AC Filters/Chokes•Stack•Meters

Meetings
