This presentation outlines how OSIsoft's PI System data is leveraged to provide key information about an asset’s health and can be combined with maintenance records to improve operational efficiency. Every time an asset fails, the operational efficiency is being affected, as it depends on the asset readiness and availability. To improve efficiency, an effective maintenance plan is needed and that requires a significant amount of clean and reliable data. Getting access to such data can be very challenging. Prenscia Engineering Solutions is working with the OSIsoft team to provide a complete solution that can be implemented without spending years of planning and execution. Our approach combines both operational data (PI System) and maintenance data (CMMS Systems) to improve the data quality, capture and verify the maintenance events, perform criticality analysis and assess the health of the asset.
