Prepare engineering information
Prepare drawing metadata and review extracted equipment, instruments, lines and tags against the source.
VISCOS / AI-assisted process safety & risk management
AI-assisted engineering.
Built for process safety.
VISCOS connects engineering documents, HAZOP, LOPA and SIF design and performance analysis. Use AI to prepare information and study drafts, with engineers reviewing the work.

See how AI helpsPrepare engineering information and study drafts. Carry reviewed context into LOPA and SIF.
Follow the work on a unit: review its drawing, develop a scenario, assess the protection and model the protective function. Each stage retains the engineering context.
AI across VISCOS
AI assistance from the drawing to the study.
VISCOS uses drawing information, selected study records and your risk criteria to prepare context and propose analysis. Review suggestions individually or in a batch, then decide what becomes part of the study.
Shape the study
Propose a template from a prompt or reference image, then review its structure and configure the fields.
Develop the analysis
Draft causes, consequences, safeguards and recommendations using the selected scenario and risk criteria.
From context to a draft

Reviewed study records
Accepted drafts can be edited in the study and carried into connected assessments.
The reviewed context carries forward.
Accepted HAZOP records connect to LOPA and SIF requirements. Engineers assess protection and design the function; configured methods calculate risk and numerical performance.
01 / Engineering information
Start with the drawing.
Bring engineering documents into the unit. Review extracted P&ID equipment, instruments, lines and tags against the original drawing, then use that information to define the study context.
- Drawing metadata and revisions
- Review and correction of extracted elements
- Equipment and node context for the study
Reviewed process information becomes a starting point for the assessment.

02 / Hazard studies
Keep the scenario connected.
Work through a Hazard and Operability study (HAZOP) with related nodes, deviations, causes, consequences and safeguards. Adapt the setup and saved views to the task, with shared risk criteria and configured calculations.
- Connected study hierarchy
- Configurable fields and saved views
- Deterministic risk calculations and matrix lookup
The worksheet keeps each analysis step within its engineering context.

03 / Layer of Protection Analysis
Carry the scenario into LOPA.
Open a linked assessment from a HAZOP consequence. Define initiating events, assess protection-layer credit and inspect the remaining risk and required risk reduction, with the source scenario still in reach.
- Linked sources and historical context
- Qualification and independence assessments
- Risk calculations, gaps and recommendations
A safeguard needs evidence and assessment before it can receive protection-layer credit.

04 / Functional safety
Connect requirements to the protective function.
Carry LOPA requirements into a Safety Instrumented Function (SIF). Model sensors, logic solvers and final elements, then inspect numerical performance with the reliability inputs, methods and assumptions behind it.
- Source-linked requirements and design evidence
- Subsystem layouts, voting and reliability inputs
- Numerical performance, saved runs and freshness context
Performance analysis supports Safety Integrity Level (SIL) work. Achieved SIL and formal approval remain separate engineering decisions.
