HAZOP and What-If
HAZOP on P&ID nodes, with the copilot.
Use this add-on:
Screenshots and a short video come with the listing (AL.3).
Overview
Planned. This add-on is not built and no host app mounts it. HAZOP and What-If is planned as a worksheet on the P&ID itself (roadmap rows CH.14 and CH.30). The intent is to draw a node on the P&ID in CadCraft, mark it in MarkupCraft, and record guide words against parameters with causes, consequences, safeguards and actions, saved with the drawing. Row CH.30 plans an assistant copilot that drafts rows as suggestions the team accepts or rejects. A worksheet library exists in the lab; no app uses it yet.
Who it’s for
- Process safety facilitators who run hazard studies on a P&ID.
- Process and instrument engineers who take part in the sessions and own actions.
- Project teams who want actions tracked to closure.
What you can do
- Nothing works yet. Planned: nodes on the P&ID, guide word and parameter pairs, a worksheet of causes, consequences, safeguards and risk ranking, action tracking with owner and due date, and a report as PDF or spreadsheet (CH.14).
- Planned: an assistant, through the connected-AI tools, that proposes rows as suggestions; it may not accept, reject, delete or close anything (CH.30).
Methods and standards
Planned after the IEC 61882 guide word vocabulary. The risk matrix is data you supply; the library's default matrix is labelled as an example. Nothing here is a method approved by a regulator.
Data and sources
The worksheet is planned as data saved with the drawing. Severity, likelihood and the risk matrix are the team's own. No failure data is bundled.
Verification
Planned: no add-on test yet. The engine library behind it has a test, tools/process-test/test-safety.mjs, which the session log chem-safety_PART_3 records as 151 passed, 0 failed on 2026-10-28. It checks the library's arithmetic and file handling, not an add-on, and not against a worked example from a published guideline.
Limits
Not built as an add-on: drawing the node boundary, MarkupCraft markers, the worksheet screen, saving into the drawing, PDF and spreadsheet files, registering the assistant tools with a host, and any run with a real assistant. A HAZOP is a team study; the worksheet records it and does not replace the team or the facilitator.
Files and formats
Planned: the worksheet saved inside the drawing, plus a CSV and spreadsheet export and a printable report. Nothing is written by an app today.
Get started
