Use of Hexagon PAS PSI Test

The Hexagon PAS PSI test is a specialized assessment designed to evaluate a candidate’s proficiency in using Hexagon’s Process Safety Information (PSI) module within the PAS Suite. This tool plays a critical role in process industries by centralizing safety-critical information, improving operational integrity, and supporting regulatory compliance efforts.

In today's high-risk industrial environments—particularly in sectors like oil & gas, chemicals, energy, and manufacturing—ensuring that personnel can effectively manage and interpret process safety information is vital. Hiring teams need a reliable way to validate that potential hires can confidently work with the PSI module, adhere to best practices, and contribute to the overall safety and reliability of operations.

This test focuses on core functional and technical competencies required to use the Hexagon PAS PSI system effectively. It covers essential skill areas such as document navigation, PSI configuration, integration with control systems, change management workflows, and compliance documentation. The assessment simulates practical, real-world tasks, allowing employers to gauge not only product knowledge but also situational judgment in safety-related workflows.

By using the Hexagon PAS PSI test as part of the hiring process, organizations can streamline the selection of candidates who are not only technically proficient but also aware of the safety and compliance implications of their work. This results in reduced onboarding time, enhanced process safety performance, and greater confidence in employee readiness for safety-critical roles.

Skills measured

Assesses the candidate's knowledge of alarm system fundamentals, focusing on event categorization, alarm priority assignment, bad actor detection, rationalization methods (D&R), nuisance alarm elimination, and alarm lifecycle tracking. Includes analysis of alarm floods, stale alarms, standing alarms, and compliance with ISA-18.2 and EEMUA 191 standards.

Evaluates understanding of loop health indicators like variability index, valve travel deviation, loop uptime, dead time, and manipulated variable trends. Covers loop benchmarking, identification of poor control performance (e.g., hunting, saturation), and use of statistical tools like power spectrum and correlation analysis to diagnose process anomalies.

Tests the ability to define and configure physical, design, and safe operating limits across process equipment. Includes development of hierarchical limit structures, configuration of alarm zones, deviation monitoring, and proactive visualization of boundary breaches to avoid safety margin erosion and regulatory non-compliance.

Measures proficiency in implementing and managing Instrumented Protective Layers (IPLs) including configuration of test intervals, bypass logic, demand frequency analysis, and maintenance tracking. Evaluates ability to generate compliance reports, analyze IPL failures, and contribute to HAZOP/SIL reviews by integrating IPL performance with safety lifecycle requirements.

Assesses control loop diagnostics, process model identification, and application of tuning strategies for closed-loop systems. Includes simulation of setpoint tracking and disturbance rejection, identification of under/over-tuned loops, performance evaluation under different process conditions, and robustness checks for advanced control scenarios.

Evaluates theoretical and applied understanding of international standards like ISA-18.2, EEMUA 191, and IEC 61511 related to alarm management. Covers alarm philosophy creation, bad alarm behavior detection, flooding control strategies, alarm rate benchmarks, and methods to reduce operator alarm load and improve situational awareness.

Focuses on advanced AlarmManagement features such as Audit & Enforce for policy adherence, Alert Director for event-driven automation, and dynamic alarming techniques that change alarm behavior based on process mode, time of day, or operating conditions. Includes knowledge of audit logging, governance reports, and automation-driven alarm conditioning.

Tests the use of analytical tools like power spectrum analysis, time-series correlation, and cycle analysis to detect hidden process issues, control loop interactions, oscillations, and anomalies. Also includes use of time-domain trend overlays, frequency-based signatures, and detection of override scenarios in advanced control loops.

Assesses the ability to generate and interpret dashboards and risk heatmaps that depict IPL compliance, test overdue alerts, bypass violations, demand tracking, and safety-critical alarm behavior. Candidates are tested on actionable analytics for plant safety teams, visual integration into SIL and risk matrix frameworks, and continuous improvement loops.

Evaluates end-to-end architectural understanding of PAS PSI suite deployment and integration with external systems like DCS/SCADA, Historians (e.g., PI), SIS platforms, and cloud or enterprise reporting tools. Includes defining cross-platform data flows, ensuring alarm philosophy compliance, and designing enterprise alarm and control loop governance strategies.
