Every change, every impacted document — found.
Rastro reads your Management-of-Change documents, maps your engineering deliverables into a living knowledge graph, and shows you exactly what each change touches — then drafts the updates. Engineering document intelligence, by Huracán.
Proof
Tested on a plant it had never seen.
We validated Rastro with Shell ETCA on 15 real changes from a unit that was never in the data Rastro was built on.
Validated with Shell ETCA
Tested in 2026 on real changes from a Shell unit, as part of a running pilot.
Built on TU Delft research
The knowledge-graph method behind Rastro was developed and defended as MSc research at TU Delft.
What Rastro learned on this unit also improved its results on the plants it was built on, so the gain carries to the next plant. We keep testing on plants we have never seen.
How it works
From a change document to a finished update.
Rastro runs the chain an engineer would — only across your whole document set at once, and without missing a link.
Ingest
Drop in your MoC scope documents and the deliverables they affect. Rastro parses each document type and extracts the entities inside.
Build the graph
Entities and their dependencies become a knowledge graph, so related documents, systems and requirements are linked — not siloed.
Analyse impact
For any change, Rastro traces the graph to surface every downstream document and clause that needs attention.
Generate updates
It drafts the targeted edits to each impacted document, ready for your engineers to review, refine and sign off.
Use cases
Which of these would make the biggest difference at your sites?
Most of the value sits before a change is approved: a complete scope and a known impact.
Plan a change
Scoping a change
A supplier switch becomes a ready scope: SDS, recipe, PHA, interlocks, work instructions.
Impact before approval
Compare options on what each one reopens, before the MoC board decides.
Turnaround & campaign planning
Run all planned modifications together and see overlaps before the window is set.
Replacement projects
End-of-life pumps or instruments: connections and documents gathered from the asset.
Execute & assure
Standard & permit updates
A revised standard or permit condition traced to every procedure that refers to it.
BRZO / PSM audit evidence
Per change: what was updated, and which evidence is still missing.
As-built alignment
After field work, find the drawings and procedures that no longer match the plant.
Legacy P&IDs into a graph
Scanned P&IDs turned into a connected, searchable model of the unit.
See it in action
Watch Rastro trace a change end to end.
What's inside
A knowledge graph that understands engineering documents.
Knowledge graph & dependency inference
Rastro extracts the entities from your documents and links them into a knowledge graph, with the dependencies inferred across your deliverables.
Impact analysis
Trace a single scope change through the graph and get the complete set of affected documents and clauses — nothing slips through.
AI document generation
Rastro drafts the actual updates — into DOCX and XLSX deliverables — so your team starts from a redline, not a blank page.
Security & isolation
Built for confidential engineering work.
Every client runs in its own isolated stack — separate database, separate graph, separate storage. Single sign-on gets your team in; nothing leaves your tenant.
Isolated per company
Your documents, graph and database live in a dedicated stack — never shared with another client.
Single sign-on
One Huracán login takes each user straight to their own workspace, with access enforced centrally.
On your infrastructure
Rastro runs on Huracán-managed infrastructure — the AI processing stays inside the network.
