Functional Safety

Functional Safety Assessment (FSA)

A Functional Safety Assessment is an independent review of your Safety Instrumented System (SIS) lifecycle to verify compliance with IEC 61508 and IEC 61511. FSAs are required at multiple stages (FSA 1–5) and provide assurance that your safety systems are correctly specified, implemented, and maintained.
 

What we deliver:

 
• Independent audits at all lifecycle phases
• Gap analysis against IEC standards
• Recommendations for corrective actions
• Documentation for regulatory compliance and internal governance

SIL Determination & Verification

Safety Integrity Level (SIL) defines the risk reduction capability of a Safety Instrumented Function (SIF). We help you determine the required SIL using risk graphs, LOPA, and quantitative methods, then verify that your design meets these requirements.
 

What we deliver:

 
• SIL determination workshops with multidisciplinary teams
• Layer of Protection Analysis (LOPA) for risk quantification
• SIL verification calculations for hardware and software reliability
• Compliance reports for regulators and insurers

Safety Requirements Specification (SRS)

The SRS is the blueprint for your SIS design, detailing functional and integrity requirements. A well-structured SRS ensures clarity, traceability, and compliance throughout the lifecycle.
 

What we deliver:

 
• Development of complete SRS documents
• Clear definition of SIFs, response times, and proof test intervals
• Integration with process control and alarm systems
• Templates aligned with IEC 61511 best practices

SIS Design & Implementation

We design and implement Safety Instrumented Systems that meet your SIL targets and integrate seamlessly with your process control architecture. Our approach balances technical rigor and operational practicality.
What we deliver:
 

• Hardware and software architecture design
• Selection of certified components and logic solvers
• Proof test planning and maintenance strategies
• FAT/SAT support and commissioning assistance

Functional Safety Management (FSM)

Functional Safety Management ensures that policies, procedures, and responsibilities are in place to maintain compliance and performance throughout the SIS lifecycle.
 

What we deliver:

 
• Development of FSM frameworks and governance structures
• Training for engineers and operators on IEC standards
• Periodic audits and compliance checks
• Integration with cybersecurity and asset management systems
