Environmental MPC is modernizing workflows to maintain active, accurate data with a mind towards transparency and standardization across refining assets using a two-phase project. The first phase creates PI hierarchies representing physical sites and generates Vision displays, calculation rollups and dependent references.  Phase 1 has been completed at 3 of 15 sites. Vision displays are being published in Asset Intellect.  Phase 2 leverages PI and introduces data substitution through IOTA and data sandboxing through Seeq.
