Hazard Analysis and Risk Assessment in the Process Industry

In the case of used machines, equipment, or installations, modernization is often necessary. In such situations, it is essential to perform an analysis of how the modernization affects the overall safety. This analysis replaces the comprehensive hazard and risk assessment typically applied to new systems, and focuses solely on the changes introduced in design, control systems, or operating conditions.

Scope of the Service Includes:

Hazard and Operability Analysis (HAZOP) of process installations in accordance with PN-EN 61882-1:2016. We identify potential hazards and hazardous scenarios and assign initial risk levels based on the risk matrix provided by the client. The analysis also highlights weaknesses in the design, saving time on future system modifications.
Selection of protective measures based on applicable standards – For installations covered by harmonized standards, we optionally supplement the existing list of safety functions with protective measures required by those standards.
SIL Level Assignment – Each safety function is assigned the required Safety Integrity Level (SIL) in accordance with PN-EN 61511-3:2017, allowing an acceptable risk level to be achieved for specific failure scenarios. The most commonly used SIL assignment methods in process installations include: Risk Graph, Layer of Protection Analysis (LOPA), and Risk Matrix. The choice of method depends on client requirements. EXPERTLY-PRO specialists perform the analysis using a method tailored to client preferences. We are ready to assist in selecting the optimal method based on your data.
Preparation of installation safety instructions – Some of the hazards identified during the risk analysis must be mitigated through organizational measures. These measures, defined during the risk analysis, are continuously incorporated into the machine’s operation and maintenance manual.

If you need a comprehensive hazard and risk analysis with the assignment of SIL integrity levels, contact us — we’ll assist you throughout the entire process.
