8:00 AM - 3:00 PM
Registration: US$250
Organized By: Pioneer Motor Bearing Co.

Who Should Attend: Operations, Maintenance, and Engineering Staff from Utilities and Owners as well as Designers, Engineers, and Field Personnel from Hydro OEM’s

Course Overview: Back by popular demand! As the title for this event indicates, this will not be a lecture or a presentation of a paper; rather, it will be an interactive discussion among attendees and a panel of fluid film bearing specialists. Panel members are experts in 
the analysis, design, application, installation and maintenance of bearings in hydroelectric service. By surveying in advance both prospective and registered attendees, we will determine the most challenging types of bearing problems for end users, and collect specific past or current bearing “headaches”, all of which will be discussed and debated by panel members to identify root causes and practical possible solutions. Our objective is to provide non-commercial, moderated advice, analysis and recommendations, both from the panel and fellow attendees as well, in an open discussion, with relevant comments from all encouraged. The specific issues to be addressed will be largely governed by the results of our surveys. We expect to cover subjects on both thrust and guide bearings including potential design modifications, operational and assembly procedures, and material substitutions. Note: due to time constraints, it is possible that we may not be able to discuss all topics submitted by prospective attendees. There will be a lunch break but food will not be provided. Please take our online survey now by clicking this link: http://www.pioneer1.com/hydro2014. Pioneer will select a number of surveys that provide good topics of discussion or questions that wish to be answered. Attendees who submit surveys that are selected by Pioneer will be reimbursed their full registration fee!


MARCUS CRAHAN PE,  Director of Power Engineering since 1989.  More than 30 years of experience as an engineering consultant specializing in the failure analysis and performance testing of large rotating machinery. Marcus is a globally recognized expert in the performance of root cause investigations of capital equipment failures, especially the hydroelectric industry. Vastly knowledgeable on the subjects and intricacies electrical machinery, including their design, manufacturing, operation and maintenance processes.  

FRED C. WIESINGER, JR., Technical Services Manager, Pioneer Motor Bearing Company, since 2001. Mr. Wiesinger has extensive experience with the manufacture, repair and modification of thrust bearings for large vertical hydroelectric turbine-generators. Prior to Pioneer, he spent fourteen years at Kingsbury, Inc., where among other positions he served as chief engineer.

LYLE A. BRANAGAN, PH.D., Engineering Manager, Pioneer Motor Bearing Company, since 1996. Dr. Branagan has performed advanced research on temperature gradients in fixed geometry and tilting pad bearings. For a decade, he served Pacific Gas & Electric Co. as a rotordynamics engineer, gaining substantial design and operations experience with bearings and vibration in hydroelectric, fossil, geothermal and nuclear power stations. He was an integral member of the start-up team for PG&E’s Helms Pump Storage Generating Station. Dr. Branagan has published numerous articles and papers and lectured extensively for the Electric Power Research Institute, in addition to conducting training sessions for engineers at electric utilities.

DR. CHRIS ETTLES, Professor Emeritus, Rensselaer Polytechnic Institute, Troy, NY. Dr. Ettles is a noted expert on tilting pad thrust bearings. Over a span of three decades he created and refined GENMAT, the only software code that makes it possible to perform a thorough analysis of spring-bed supported thrust bearings. Dr. Ettles is a Fellow of the STLE and received the Captain Alfred E Hunt Award in 1988. Dr. Ettles has been a consultant to such leading companies as General Electric and Voith Hydro.
