Worksheet, configurable risk criteria, LOPA, SIF definitions, actions, incidents, team and session records, and a formal close-out report with sign-off — all in one workspace.
Sign-off fields support your internal review workflow. Asphalyn does not certify or approve engineering outputs; every study and deliverable must be independently reviewed and approved by qualified personnel.
Not a worksheet tool with reporting bolted on. Not a reporting tool missing the worksheet. The workflow and the deliverable in one place.
Nodes, guidewords, and parameters, with as many cause–consequence scenarios under each deviation as the team identifies — each with its own safeguards, recommendation, and risk. Inline editing saves automatically; nodes reorder by drag.
Four matrix presets or your own custom matrix — up to 10 levels per axis, with your own band boundaries and level definitions. Every row snapshots the matrix in force at creation, so a historical assessment always reads the same as the day it was approved.
IPLs with PFDs and the three conditional modifiers IEC 61511 expects — P(Ignition), P(Personnel Presence), P(Fatal Injury). Each workspace sets its own acceptability threshold; drift against the current policy is flagged with one-click re-evaluation.
Capture the SIF definition on the scenario it protects against — function, target SIL, sensor, logic solver, final element, voting architecture, proof test interval, safe state, response time. Every SIF compiles into a SIF Register in the export.
Turn a recommendation into a tracked action in one step, linked back to its source row. When one remediation closes several deviations, link it to multiple HAZOP rows and track it once.
Record incidents, link them to a node, resolve with a comment, and generate actions directly from an incident. Severity, category, type, and status tracked end to end.
Record who attended, when each session took place, and which documents were consulted. All three appear as their own sections in the exported report.
A per-action register followed by one response sheet per action, each ending with Prepared By / Reviewed By / Approved By sign-off. Available in PDF, Word, or Excel.
The tool should stay out of the way while the room works, and produce the deliverable when the room is done.
Asphalyn connects the complete HAZOP lifecycle in one workspace. Create studies, assess risks, manage actions, track incidents, and generate audit-ready reports without disconnected tools.
Create a new HAZOP study with project information and metadata.
Break the process into logical nodes and capture design intent.
Identify deviations, causes, consequences, safeguards, and recommendations.
Convert recommendations into actions and monitor completion.
Record incidents and connect them with your HAZOP studies.
Export PDF, Word, Excel, and CSV — including a formal close-out report with per-action response sheets and sign-off.
Start free. Upgrade when you need to export or run a second study. Per workspace, not per seat. No hidden user fees. No annual lock-in.

Every paid workspace includes the full workflow. Upgrade only when you need collaboration or more seats. All plans are billed per workspace and can be cancelled at any time.
“Unlimited exports” means unlimited within normal usage. If your usage is significantly above normal patterns, we may contact you to discuss your needs. We will never silently throttle or block your exports.
Asphalyn is built for real HAZOP work, so the questions below focus on what the platform actually lets you do today.
Run a real study end to end — the worksheet, the LOPA, the actions, the incidents, and the close-out report in one workspace.
