CeraPHA Studio is a process hazard analysis workbench: HAZOP and HAZID worksheets, LOPA scenarios and SIL determination live in one auditable study file, so the safeguards you credit in a workshop are the ones you verify afterwards.
A PHA study produces hundreds of nodes, deviations, causes, consequences and safeguards, and the same safeguard is often credited in many places. CeraPHA Studio keeps every one of them as a linked object — change a safeguard once and every worksheet, LOPA scenario and SIF record that uses it updates.
The application follows the IEC 61511 front-end lifecycle: hazard identification, risk ranking against your matrix, layer-of-protection analysis with independent-protection-layer rules, and SIL determination that feeds the Safety Requirements Specification.
Guideword-driven worksheets with node definition on P&ID references, risk ranking and action capture — built for live facilitation.
One library of safeguards shared across nodes; IPL credit rules (independence, effectiveness, auditability) enforced in LOPA.
Initiating-event frequencies, enabling conditions, conditional modifiers and IPL PFDs with risk-gap calculation to the corporate target.
Risk-graph, risk-matrix or LOPA methods; SIF register with target SIL and required risk reduction.
Actions with owners, due dates, evidence and closure status; exportable action register.
Study reports, worksheets and registers to Word/Excel; revalidation mode compares the current study against the previous cycle.
Import node list and P&ID references; choose guidewords and risk matrix.
Record causes, consequences, safeguards and actions node by node.
Screen scenarios into LOPA; determine SIL for each safety instrumented function.
Issue the PHA report, SIF register, action register and SRS input.
