What AVEVA PI System is genuinely good at
The PI System is the reference implementation for industrial time-series data, and it earned that position. For high-frequency process historian data — collecting it reliably, storing it at scale, retrieving it fast, and giving engineers tooling to analyse it — it is mature, widely deployed, and deeply integrated into control-system estates. If the question is what a plant was doing at a given moment, PI answers it.
Where buyers find its edges
It is a historian first. Inspection data is not time-series data: a thickness reading at a condition monitoring location is a sparse, manually captured, procedure-governed measurement whose meaning depends on where it was taken, who took it, what they were qualified to do and which instrument was used. Representing that faithfully in a historian-shaped model takes work, and the integrity workflow around it usually lives elsewhere.
How Atlantis differs
Atlantis is built around the sparse inspection measurement rather than the dense process signal. Condition monitoring locations, corrosion rates, remaining life and the evidence chain behind each number are native concepts, not things modelled on top of a tag structure. The two are complementary more often than competitive — process history explains why corrosion accelerated; the inspection record establishes what the wall is now.
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 Atlantis Digital Twin a direct replacement for AVEVA PI System?
No — they overlap but serve different jobs. PI System is fundamentally a real-time process historian: it excels at high-frequency time-series capture from PLCs and DCS for process variables (temperature, pressure, flow). Atlantis Digital Twin is an inspection-data-led integrity twin: it excels at storing and visualizing thickness grids, defect maps, FFS calculations, and RBI scoring on a 3D asset model. Many customers run both — PI as the process historian, Atlantis as the integrity twin — and we connect to PI via OPC-UA or PI Web API to pull the corrosion-relevant tags (skin temperature, dew point, sulfur content) into the asset record.
Can I integrate Atlantis with my existing AVEVA PI investment?
Yes — this is one of our most common deployments. Atlantis pulls process tags from PI via the PI Web API (REST) or OPC-UA bridge. We typically map 50–200 corrosion-relevant tags per asset (skin temperatures, fluid composition, operating pressure, dew point) into the asset record so RBI scoring and CML thickness predictions stay in sync with actual operating severity. No PI-side configuration changes are required beyond a service account with read access.
Which is better for FFS (API 579) calculations?
Atlantis ships with a native API 579-1/ASME FFS-1 Level 1, 2, and 3 calculator covering general metal loss, local metal loss, pitting, blisters, and crack-like flaws. PI System has no native FFS engine — customers typically run FFS in standalone tools (Becht's FFS software, E2G's PlantStream, or custom spreadsheets) and post the results back. If FFS is core to your integrity workflow, Atlantis removes a tool from the stack.
What is the migration path if we already have a PI Asset Framework hierarchy?
We import your AF asset hierarchy via the PI Web API in a one-time mapping step (1–2 weeks). Equipment IDs, parent-child relationships, and tag-to-asset bindings transfer automatically. CML locations from your existing IDMS (Meridium, Antea, GE APM) layer on top via a separate import. Most customers are running Atlantis side-by-side with PI within 30 days, with full integrity workflow live by week 12.
