Atlantis Digital Twin vs OSIsoft PI
Atlantis DT and OSIsoft PI serve different parts of the asset integrity stack. PI captures process data; Atlantis layers NDT findings onto a 3D model. Joint deployment patterns, integration cost, and TCO compared.

What OSIsoft PI (now AVEVA PI System) is genuinely good at
OSIsoft built the industrial data historian category, and the product now sits within AVEVA. Its strengths are the ones described for the PI System: reliable high-frequency collection, long-horizon storage, and an analysis ecosystem engineers already know.
Where buyers find its edges
The same boundary applies. A historian answers questions about process behaviour over time. Fixed-equipment integrity asks a different question — what condition is this component in, on what evidence, and what does that permit it to do — and that question is governed by inspection codes rather than by process data.
How Atlantis differs
Atlantis binds examination results to asset geometry and carries the qualification, calibration and procedure evidence with them, so an integrity decision can be reconstructed later. Where a PI estate already exists, the sensible architecture is usually both: process history feeding damage-rate understanding, inspection records establishing condition.
Choosing between them honestly
The useful question is not which platform is better but which problem you are solving first. If the dominant problem is process behaviour, rotating-equipment reliability, or engineering geometry, the platform built for that will serve you better and you should buy it. If the dominant problem is fixed-equipment integrity — establishing condition from examination, defending an interval, and producing evidence years later that the decision was sound — that is the problem Atlantis was built around. Estates of any size usually end up with more than one system, and the integration boundary is worth designing deliberately rather than discovering later.
What to test during evaluation
Ask each vendor to load a real corrosion circuit from your own data, with its measurement history, and to show the remaining-life calculation and the evidence chain behind it. Ask what happens when a procedure is revised — whether prior results remain associated with the revision in force at the time. Ask how data leaves the system if you stop using it. Those three questions separate platforms faster than any feature matrix, and they are the ones a demo script does not anticipate.

Frequently Asked Questions
Is OSIsoft PI different from AVEVA PI?
Functionally, no. OSIsoft was acquired by AVEVA in 2021 for ~$5 billion. The product is the same code base — what was OSIsoft PI System is now AVEVA PI System, sold and supported by AVEVA. Customers on legacy OSIsoft enterprise agreements have been migrating onto AVEVA Flex licensing over 2022–2026. References to ‘OSIsoft PI’ in the wild today usually mean a pre-2021 deployment. The technology, comparison points, and the core differences vs Atlantis Digital Twin are identical.
What about my existing OSIsoft Enterprise Agreement?
AVEVA has been honoring OSIsoft EAs through their renewal cycles, then converting them to AVEVA Flex subscription. If you’re on a legacy perpetual + maintenance agreement, you’re paying ~22% annual maintenance. Switching to AVEVA Flex generally raises annual cost but adds cloud bursting, AVEVA Connect access, and consolidation across your AVEVA estate (E3D, Unified Operations, etc.). None of this changes the core question for inspection teams: the historian platform is not designed for NDT data, and you typically still need a separate IDMS for the integrity workflow. Atlantis Digital Twin replaces that IDMS layer and adds the 3D twin.
Can I keep OSIsoft PI as my historian and add Atlantis as the integrity layer?
Yes — this is the most common deployment for tier-1 operators with an existing PI footprint. We connect via the PI Web API (REST) using a service account with read access. Typical mapping is 50–200 process tags per major asset (skin temperatures, fluid composition, operating pressure, dew point, sulfur content) brought into the Atlantis asset record so RBI scoring and corrosion rate predictions stay in sync with operating severity. No PI-side schema changes required.
Which platform is more future-proof?
Both have strong roadmaps. AVEVA is investing heavily in PI’s cloud transition (AVEVA Connect, AVEVA Data Hub) and AI/ML on top of historian data. Atlantis is investing in inspection-specific AI (defect classification on RT/PAUT, predictive corrosion modeling, automated FFS), expanded EAM connectors, and IEC 62443 OT cybersecurity. Choose based on whether your dominant future workload is process-control intelligence (PI) or inspection integrity intelligence (Atlantis). Many operators run both for exactly this reason.
