The Atlanta Metro Chapter meetings of the Georgia Society of Professional Engineers are open to engineering professionals, students, and other interested members of the public. They are held monthly, September through June, on the second Monday of each month. The meetings start with networking at 6:00 pm, followed by dinner and the speaker.
March Monthly Meeting
Atlanta Metro Chapter
Time: 6:00 PM
Date: Monday, March 9, 2020
Location: Piccadilly Cafeteria, Northlake
Presentation: Stopping Corrosion of Side-by-Side Utilities
Speaker: Bryan Evans, Senior VP of the Energy Market sector with Pond & Company
Most anything can corrode. Naturally occurring ores are processed to extract and purify metals making alloys that are key materials of the infrastructure. Exposure to water, the air, and various chemicals, even weak acids such as acid rain, biologic processes, and electric fields can cause a chemical alteration, essentially reversing the refining processes. This alteration, known as corrosion, causes significant damage. Rusting steel reinforcing in concrete swells and causes the concrete to fail. Pipelines and storage vessels may lose structural or hydraulic integrity. Structural components lose strength and can fail; sometimes suddenly with catastrophic and tragic affects. The conductivity or insulating properties of electrical components change. The impact is estimated to be 3% of the total world economic output. The modern pipelines, hazardous material handling, energy distribution systems, utilities and transportation infrastructure are not immune.
Add to that the effects of packing systems together in obvious and nonobvious ways. As crowded as a city like Atlanta may seem, it is even more so underground, where mass transit and utilities are located. Acquiring the land and permits for new utility routes can be costly and construction can be very disruptive. Many North American metropolitan areas route different utilities underground side by side in “joint use” utility corridors or underground chambers. New pipelines conveying natural gas, or high pressure steam, or water may be near high voltage power lines. The operation of HVAC transmission systems can produce what is known as “stray current”. Induction of AC voltage causing stray current, under certain conditions, can cause corrosion of structures, personnel safety issues, and integrity concerns with assets. Proper evaluation, design, construction, operation monitoring, and maintenance of the assets affected by Induced AC will mitigate the detrimental effects of such stray current.
Bryan Evans, Senior Vice President of the Energy market sector with Pond and Company will address the 6:00 PM, Monday, March 9th monthly dinner meeting of the Georgia Society of Professional Engineers at the Piccadilly Cafeteria located at 2000 Crescent Centre Blvd in Tucker. He will present on Induced AC Interference Induced Corrosion & Mitigation for Joint Use Utility Corridors. The discussion will cover how alternating current from HVAC transmission structures can be induced on structures within joint use corridors. The talk will also address the three primary concerns related to Induced alternating Current: AC Corrosion, Personnel Safety and Asset Integrity. In addition, the talk will cover Best Practices to prevent occurrence and how to mitigate the issue. Currently registered professional engineers, those engineers aspiring to become PEs, and others engaged in engineering would benefit from the presentation. Members of the general public are also welcomed to learn about technology, engineering and public welfare.
Bryan has a B.S. in Civil Engineering Technology from Southern Polytechnic State University and is certified by NACE International (National Association of Corrosion Engineers) as a Cathodic Protection Specialist, Senior Corrosion Technologist and Coating Inspector Level I. Bryan is also certified by American Petroleum Institute as an API 570 Piping Inspector. Bryan has taught various Corrosion Courses including this topic at the Appalachian Underground Corrosion Short Course (AUCSC) at West Virginia University for the past five years. He has more than 25 years of experience working and consulting on both corrosion control and asset integrity in oil and gas industries and other industries worldwide.
About The Meeting
The GSPE Atlanta Metro Chapter meetings are open to engineering professionals, students, and other interested members of the public. The meetings take place on the second Monday of each month, September through June. The March 9th meeting will be at The Northlake/Tucker Piccadilly Cafeteria, 2000 Crescent Centre Blvd., Tucker, Ga. 30084. Many engineers enjoy the presentations as well as earn a required Professional Development Hour. The meetings start with networking at 6:00 pm, followed by dinner and the speaker. RSVP to Ken Quintana at 770-827-8627, or email@example.com with GSPE RSVP in subject line or through www.meetup.com/Georgia-Society-of-Professional-Engineers-Atlanta-Metro/ is appreciated.
