Atlantis Digital Twin vs Hexagon EAM

Atlantis DT focuses on NDT-overlay 3D visualisation; Hexagon EAM is a full enterprise asset management platform. Comparison of inspection workflow, RBI/RCM integration, and total cost.

What Hexagon EAM is genuinely good at

Hexagon EAM is a mature enterprise asset management system with strong maintenance execution, work order management, spares and materials, and the organisational reach that a full EAM deployment brings. For running a maintenance function at scale it is a serious, established product.

Where buyers find its edges

EAM and inspection integrity overlap without being the same thing. An EAM manages work — what needs doing, who does it, what it consumed. Integrity management asks whether equipment is fit to continue operating, which is a code-governed technical judgement resting on measurement history and damage mechanism understanding. EAM systems typically hold the inspection as a completed work order rather than as a technical record with evidence behind it.

How Atlantis differs

Atlantis holds the technical record and the reasoning: measurement locations, rates, remaining life, the mechanism assumed and the evidence supporting the interval. It is designed to sit alongside an EAM, feeding it the work that integrity requires, rather than to replace maintenance execution.

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 Hexagon EAM the same as Infor EAM?

Hexagon acquired Infor EAM’s product line in 2021 and rebranded it as part of HxGN EAM. The product roots go back to Datastream 7i — a deep, mature EAM platform with particular strength in industrial maintenance, MRO, fleet, and facilities. So ‘Hexagon EAM’ and ‘HxGN EAM’ refer to the same platform with the Hexagon badge today; legacy ‘Infor EAM’ references in your environment are the predecessor brand.

Why would I pick Atlantis over a full EAM like Hexagon?

You wouldn’t — if your central need is enterprise asset management (work orders, preventive maintenance scheduling, MRO inventory, technician dispatch, contracts). Hexagon EAM is built for that and does it well. Many operators run both: Hexagon EAM for maintenance scheduling, Atlantis Digital Twin for inspection integrity, with a clean integration between them via REST.

Can Atlantis replace the inspection module in Hexagon EAM?

Often yes for the inspection-integrity portion. The inspection capabilities in any general-purpose EAM (Hexagon, Maximo, SAP PM) are designed for time-based and condition-based PM inspections, not for the depth needed in API 510/570/653 fixed-equipment integrity. CMLs, corrosion-rate trending, weld maps, and damage mapping are typically heavily customized in a general EAM. Atlantis ships with all of this native and connects back to your EAM for the work order side — ‘here’s the inspection finding, please raise a corrective work order.’

What integration looks like with HxGN EAM

Bi-directional REST integration via the EAM Web Services. Asset hierarchy and equipment master flow from Hexagon into Atlantis (one-time + ongoing sync). Inspection findings, CML thickness changes, and recommended work flow back to Hexagon EAM as Notifications or Service Requests. Implementation typically 3–4 weeks once both sides have a project sponsor. We have customers running this with Hexagon EAM 12.x and onward.
