SUBJECT: Underwater power transmission the focus of Speaking of Engineering lecture at Memorial University

DATE: March 17, 2010

Have you ever wondered about the approaches to long distance electric power transmission and delivery systems through remote terrains and subsea crossings?
On Thursday, March 18, Richard Crowdis, vice-president and project director with Black & Veatch, a leading global engineering, consulting and construction company with a mission of Building a World of Difference, will be in St. John’s to talk about approaches to long distance electric power transmission and delivery systems through remote terrains and subsea crossings.
Power transmission challenges will cause costs to rapidly expand based on distance, roughness and remoteness of terrains. Mr. Crowdis’ presentation will outline traditional approaches as well as a summary of the technologies in the high-voltage alternating current (HvAC) and high-voltage direct current (HvDC) transmission line systems. Power transmission and redundancy through subsea crossings, including HvDC transmission lines inside of large and long conduits or tunnels, will also be discussed. Finally, Mr. Crowdis will present a comparative service and cost analyses matrix for evaluation of transmission systems, including substations.
This Speaking of Engineering lecture series, hosted by the Faculty of Engineering and Applied Science at Memorial University and the Professional Engineers and Geoscientists of Newfoundland and Labrador, will be held on Thursday, March 18, at 7:30 p.m., in the S. J. Carew Building’s Angus Bruneau Engineering Lecture Theatre, room EN-2006, on Memorial’s St. John’s campus. Admission is free. Parking is available in Lot 16. All are welcome. Reception will follow.
