Vizop - The next-gen PHA software
Redefining HAZOP, HAZID, CHAZOP, Alarm Management, and more!
A modern browser-based Process Hazard Analysis (PHA) software designed by safety experts for safety experts. Eliminate documentation friction, prevent costly project delays, and focus on safety analysis rather than paperwork.
What Makes Vizop a Game-Changer?
Designed by Safety Experts, For Safety Experts
Vizop will extend to more PHA techniques soon – Future versions will support other studies beyond HAZOP with automatic data transfer and AI capabilities.
Click Less, Analyze More
Traditional HAZOP software and spreadsheets force engineers to analyze designs on a P&ID while manually typing results into separate worksheets.
Vizop changes this workflow.
The name Vizop comes from Visual HAZOP
— a method that directly links the P&ID diagram to the HAZOP worksheet, allowing users to move seamlessly between the process diagram and the analysis.
-
Direct P&ID Integration
Click directly on a P&ID device (for example a pump or pressure transmitter) to automatically transfer its name and tag number into the worksheet in just two clicks.
-
Built-in Knowledge Base
Populate worksheets instantly using a built-in database containing over 1,000 typical HAZOP scenarios, including common causes, consequences, and safeguards.
-
Bidirectional Search
Click a device on the P&ID to instantly see where it appears in the worksheet ; Click the device in the worksheet to immediately view its location on the P&ID.
Vizop replaces legacy desktop PHA tools and cumbersome spreadsheets with a modern browser-based workflow designed for collaborative HAZOP workshops.
-
Multi-Screen Workflow
Open multiple browser tabs or windows and distribute them across several monitors or projectors during workshops.
-
Dynamically Linked Windows
Update a node in one window and all other windows update automatically. Teams can discuss one issue while the scribe reviews another node simultaneously.
-
Rapid Navigation
Move instantly between nodes, worksheets, and action item lists using simple forward and back navigation.
- Process Hazards Analysis (HAZOP, CHAZOP, HAZID)
- Alarm Management & Rationalization (AR)
- Designed With Modern Philosophy
- “Visual HAZOP” via Direct P&ID Integration: Instead of manually typing out tags, users can click directly on a Piping and Instrumentation Diagram (P&ID) to define a device (like a pump or sensor). In just two clicks, the device’s name and tag number are transferred to the worksheet.
- Built-in Scenario Database: Vizop includes a database of over 1,000 typical scenarios. With one click, it can automatically populate the worksheet with predefined texts for causes, consequences, and safeguards.
- Comprehensive Annotations: Action items (recommendations), parking lot items, hold items, and assumptions can be directly attached to any element in the worksheet (such as a specific cause or consequence).
- Customizable Risk Ranking: Users can easily set up and import Risk Matrices and Priority Matrices from Excel to assign likelihood, severity, and risk levels to different scenarios.
- Massive Scale Handling: The software effortlessly imports and manages huge databases of over 10,000 alarms with zero lag or delay. It automatically handles complex imports, even when multiple alarms are listed on a single spreadsheet row.
- Advanced Alarming: Vizop fully supports setting up complex alarm behaviors designed to prevent operator fatigue, including static and dynamic (flood) suppression, first-out groups, eclipsing, and shelving.
- Bulk Editing: It features powerful tools to copy individual parameters from one alarm to many others simultaneously, drastically speeding up the alarm review process
- Fail-Safe Autosave: The software continuously autosaves every edit in the background to prevent data loss due to crashes or power outages.
- Flexible Licensing: The platform uses an online, dongle-free licensing system, but also offers emergency offline codes for remote sites.
- Total Data Retention: If a user’s license expires, Vizop switches to an “unlicensed mode.” Users can still open projects, view data, and export reports, ensuring their data is never locked away.
Software That Works For You
Engineering software should make your work easier, not more complicated. Vizop was designed with simple licensing and full data ownership in mind.
- Hardware License Dongle
- Software crash / Progress unsaved
- Data lost / inaccessible after license expires
-
Dongle-Free Licensing
Vizop uses a straightforward online license validation system, eliminating the need for hardware dongles, complex license files, or IT-heavy installations. Start the software quickly and focus on your analysis.
-
Cloud-based App
Running on an old/unstable computer? Worry-free as Vizop is a cloud-based app which will autosave all your edits instantly on our secured server and can run everywhere as long as there's internet access.
-
You Always Own Your Data
Your project data always remains accessible to you. Vizop can generate fully formatted Excel reports instantly, ready for documentation and archiving. Even if your license expires, you will still be able to open projects, view all information, and export your data whenever needed.
