Shared Learning Library
Welcome to PEMAC's Shared Learning Library, a growing body of community created knowledge, built up and maintained by the PEMAC member community. Explore a range of articles, presentations and webcasts covering a wide range of maintenance, reliability and asset management subject areas. You can even find presentations from past MainTrain conferences and PEMAC Lunch & Learn webcasts.
To easily find what you are looking for the content of the Shared Learning Library can be filtered by both Maintenance Management and Asset Management subject areas using the options in the menu to the left of the screen.

BoK Content Type:Presentation SlidesWebcastPresentation PaperBoK Content Source:MainTrain 2019Original date:Sunday, March 8, 2020As the influence of the asset management approach continues to expand within Nova Scotia Power, we need a structured approach to ensure we continue to seek opportunities to optimize maintenance strategies. In a new installation, techniques such as failure modes and effects analysis (FMEA) and reliability centred maintenance (RCM) can be used to develop an optimized maintenance strategy from the start, in a top-down approach. However, the vast majority of Nova Scotia Power’s equipment was in place long before the asset management office—and, therefore, the asset management approach—existed. The result of that is a collection of value-added, but developed after-the-fact maintenance strategies. Each maintenance strategy has components of operator surveillance (rounds), testing, predictive pattern recognition (also known as advanced pattern recognition, APR), predictive maintenance (condition-based monitoring and risk-based inspections), online monitoring, and preventative maintenance. While efforts had been made to “baseline” the equipment processes when maintenance strategies were developed (i.e., “clean out” existing activities), the organic growth of the approach and the distributed nature of assets and personnel have made this difficult to maintain. Therefore, we needed an approach to optimize existing maintenance strategies, without recreating them. Nova Scotia Power has therefore undertaken an effort known as maintenance strategy optimization, and has made this activity a core accountability for the asset management team, which recognizes the need to seek continuous improvement (vs. a one-time exercise). With a focus on digitization wherever appropriate, Nova Scotia Power has asked a number of questions to streamline, standardize, and optimize its maintenance strategies. Is there opportunity to reduce PM frequency? Is there opportunity to collect more information such that we can strengthen our APR models? Can our in-house standards be revalidated to sustainably reduce operating and maintenance costs? Nova Scotia Power is answering yes to these questions, and more, and pursuing opportunities to optimize its maintenance strategies—from the bottom up!
‘Pumping’ Technology into our ‘Sewage Pumping Stations’BoK Content Type:Presentation SlidesPresentation PaperBoK Content Source:MainTrain 2018Original date:Tuesday, April 3, 2018“Sustainability through reliability” — presented at the 2015 MainTrain Conference — focused on the rapid growth of passenger flow at Toronto Pearson Airport and how, due to this growth, we were experiencing a high number of plumbing drainage failures. We carried out an RCA on our system and came up with changes in how we would prevent drainage failures. The changes we made dealt with our plumbing design standards; food and beverage tenant fats; oil and organics recovery system; lease agreements; and maintenance practices. However, that was only the starting point. In this presentation, we’ll discuss RCA conducted, the failures experienced, and the enhancements and improvements we made to make our system more reliable.
