PlantGraph

Your whole plant, finally connected.

PlantGraph is one model of your entire plant: every piece of equipment, every connection, and everything your teams know. Here’s how it works, start to finish.

Industrial process flow diagram on a software interface showing three interconnected sections labeled 2024-NFLD-0419, 2024-NFLD-0418, and 2024-NFLD-0425, with colored lines (orange, green, pink, purple, blue) tracing flow paths between various equipment and valves. The right side panel displays details for equipment C-210, including unit classification and connected major equipment, with color-coded listings for E-211A (red), V-210 (green), P-210B (blue), and P-210A (orange). The interface has a search bar at the top, menu options for groups, systems, LOTO, major equipment, line numbers, QA, and alarms, and multiple navigation icons along the left and bottom edges.

Today, your plant lives in drawings, a historian, a maintenance system and a stack of spreadsheets. With PlantGraph, it lives in one model.

Create

One connected plant model of your facility.

Built from the schematics you already own, including decades of brownfield drawings. PlantGraph builds a complete flow representation of your facility from beginning to end, down to every flange, so you know where every piece of equipment is, what it connects to upstream and downstream and how it functions within your plant.

Import your brownfield schematics.

Bring in legacy schematics as they are, in the DXF and DWG files you already have, with no redrafting and no new data collection.

Built by algorithms, checked by engineers.

Every symbol, line and valve is detected automatically, then reviewed by engineers. Real-world schematics hold ambiguity that takes an expert to resolve, and your most critical workflows demand the highest quality.

Connected with flow end-to-end.

Navigate paths throughout the facility, understand what lies along them, and visualize what you need to do your job.

Enrich

Add what your systems and people know.

Layer governed engineering knowledge anchored to the equipment that it describes.  Once something is added, everyone can find it.

Classify equipment.

Group the equipment you manage together, like systems or corrosion circuits, so every team works from the same definitions.

Codify human knowledge.

Turn a traced route into a piping circuit or map a control loop in a few clicks.

Bring in existing data.

Easily attach operating procedures, spec information, inspection data, work orders, etc. to the equipment they belong to using the model itself.

Sustain

Kept current with every change.

Plants change every day. PlantGraph keeps the model current, along with everything your teams have added to it.

Unify updates.

When the plant changes, its diagrams, systems, circuits and instrument loops all update with it.

Versioned and traceable.

Every change is tracked, so you can see what changed, when and why, with the ability to resolve conflicts coming soon.

Always current.

Every application, agent, or person using PlantGraph gets the facility model as it is today, not an outdated drawing.
