Our Process

How we deliver Safety Systems

1

Hazard Analysis

Conduct HAZOP, LOPA, and SIL determination studies to identify safety requirements and target SIL.

2

Safety Requirements

Develop Safety Requirements Specification (SRS) defining safety functions and integrity requirements.

3

System Design

Design SIS architecture, select certified equipment, and develop cause & effect matrices.

4

Implementation

Install safety sensors, logic solvers, final elements, and program safety PLC.

5

SIL Verification

Verify achieved SIL through calculation, validate through factory and site acceptance testing.

6

Operations Support

Develop proof test procedures, maintenance schedules, and provide operator training.
