Unseen process risk
Deviations in pressure, temperature, level and reaction behavior can progress to dangerous consequences beyond normal control limits.

Process Safety
Analyse and validate hazardous processes through the IEC 61511 lifecycle, then operate them safely.
We handle process safety with an end-to-end engineering approach, from HAZOP and LOPA studies to SIL determination, SRS, SIS design, validation and proof test processes.
Explore the solution
Don't just control hazardous processes; Identify risk, manage it with independent layers of protection, and verify it throughout the lifecycle.
Insufficient risk mitigation
A single alarm or control function may not independently and reliably provide the targeted risk reduction in every scenario.
Life cycle disconnection
When analysis, design, testing, operation and maintenance records are disconnected from each other, the true state of the security function becomes invisible.
/ IEC 61511 APPROACHFrom risk analysis to operation,
From risk analysis to operation,
traceable safety life cycle.
Process safety; It covers the systematic identification of hazards, calculation of the required risk reduction and implementation of Safety Instrumented Functions (SIF) on an independent Safety Instrumented System (SIS).

- Determine the functionSafe state, response time, sensor, logic solver and end element requirements Define.
- Maintain performanceManage verification, proof testing, maintenance, bypass and change records throughout the lifecycle.
From analysis to testing,
every decision can be monitored.
The IEC 61511 approach makes the security function not a one-time automation project; It treats it as a continuous life cycle with defined responsibilities and verification gates.
Hazard and risk
assessment
Scenarios, consequences and existing protection layers are determined.
→SIL and SRS
definition
Risk mitigation and functional requirements are documented.
→Design and
engineering
Sensor, logic solver and end element architecture are created.
→Validation and
operation
The function is tested, commissioned and its performance is monitored.
/ ENGINEERING SCOPEAnalysis, hardware and documentation
Analysis, hardware and documentation
have the same security objective.
Each SIF; Process hazard is handled independently according to the targeted risk reduction and the operation-maintenance conditions of the facility.
HAZOP and LOPA support
Dangerous deviations, initiating events, consequences and independent protection layers are evaluated through structured studies.
SIL determination and SRS
Target SIL, safe state, response time, test interval, bypass and fault behaviors are included in the requirement document.
SIS architecture
Safety sensors, safety PLC/logic solver, network structure and final control elements are designed with independence principles.
SIL verification
Performance through architectural constraints, hardware fault tolerance, diagnostic coverage and proof test assumptions. is verified.
FAT, SAT and validation
Cause-effect, function scenarios, error behavior and safe stop steps are tested according to acceptance criteria.
Proof test and change
Periodic testing, failure, bypass, request, maintenance and change records are managed in a controlled manner. is supported.
Each layer is independent,
risk reduction together.
From basic process control to emergency response, each protection layer has a different task. SIS moves the process to a safe state in a defined hazardous scenario, independent of normal control.
