Event Overview
High voltage AC power transmission systems are often collocated with natural gas pipelines, and the complex interactions between the two can pose a threat to pipeline integrity and safety to personnel and the public.
In this two-day, two-hour each day workshop, we will discuss the impact that AC interference (ACI) has on the pipeline industry, corrosion symptoms, risks and threat mitigation, and the industry standards and federal regulations.
The material for this training is covered in two short (2hr) portions over two separate days.
Join us from 9:00 AM to 11:00 AM central on May 25th and May 27th.
Attendees will receive 4 Professional Development Hours upon completing this course.
Day 1:
Part 1 – What is AC Interference and How Does It Affect your Pipelines – In the first session, you’ll learn about the complex interaction between collocated pipelines and high-voltage AC power transmission systems, and the threat they pose to safety and overall pipeline integrity. We’ll review the impact of ACI on the pipeline industry, teach you how to recognize AC corrosion symptoms, and identify additional risk factors related to design and operating conditions. We’ll provide an overview of federal regulations and industry standards from organizations including NACE, INGAA, NEC and PRCI.
Part 2 – Understanding your Mitigation Options – In the second session, you’ll learn about the various mitigation and monitoring options available to you. We’ll discuss the pro’s and cons of computer modeling vs engineering field design as well.
Day 2:
Part 3 – AC Interference Threat Assessment – In the third session, you’ll learn how to implement a threat based ACI mitigation and monitoring program to help you efficiently deploy your limited field resources. We’ll define a threat assessment framework and provide you with example use cases for applying the framework for inductive coupling (accelerated corrosion) and AC fault events such as lightning strikes and HVAC upsets.
Part 4 – AC Interference Monitoring- In our final session, we’ll discuss the importance of the selection, installation and use of coupon test stations and Remote Monitoring for effective mitigation. You’ll learn how to identify AC fluctuation trends and other AC corrosion risk factors so you can be confident that you’re investing in a mitigation system that includes on-going monitoring of this dynamic environment.
