Nova Scotia Power (NSP) is an industry leader in formalized Asset Management. They recognized that in projects where data is being exchanged between systems, there are always gaps that can impact data quality and trust.
NSP’s existing MMS (Maintenance Management Systems) and Asset Performance Management (APM) solutions such as GE Predix APM, have a common equipment hierarchy that are used for diagnosis and analytics work by a broad team representing Operations, Engineering and Management. Aligning these around a single PI Asset Framework (AF) hierarchy to visualize discrepancies and to enable multiple views of the asset, offers users a “one-stop shop” approach that can support advanced analytics with trusted data.
To provide users with all available digital information related to an asset using a browser, NSP needed to upgrade their OSIsoft PI servers and leverage the existing data hierarchies across MMS and APM platforms. NSP had some legacy OSIsoft PI Servers with no PI AF capability and a long history of PI tags that, in some cases, had a reasonable structure, but in all cases, were not associated with physical assets. This required constant attention from subject matter experts. The review of the PI tags was always reliant on either a ProcessBook or Excel workbooks which invariably resided on individual users’ laptops. Unfortunately, many of the more experienced Operations and Engineering personnel are retiring and the transfer of knowledge has been a huge challenge requiring an investment in extra time and resources.
