SIL Verification & Safety Study Services
Validating Safety Instrumented Systems Under Strict ISA-84 Standards
In high-hazard sectors like oil and gas processing, refining, and chemical manufacturing, process safety systems require absolute functional integrity. Our specialized Safety Integrity Level (SIL) verification services ensure your Safety Instrumented Systems (SIS) provide dependable protection against dangerous plant conditions. We follow a systematic validation lifecycle that conforms strictly to international safety frameworks, including ISA-84 and IEC 61511.
We join your engineering pipeline immediately following the initial Process Hazard Analysis (PHA). Our team audits safety reports, identifies specific Safety Instrumented Functions (SIFs), and performs the quantitative calculations needed to verify that your safety logic solvers, sensors, and final control elements satisfy targeted risk-reduction metrics. This rigorous process helps eliminate over-engineering and ensures full compliance with OSHA’s Process Safety Management (PSM) guidelines.
Comprehensive Safety Documentation and Verification for Regulatory Compliance
Our SIL verification deliverables provide the analysis, calculations, and documentation needed to validate safety instrumented functions, demonstrate risk reduction, and support compliance throughout the facility lifecycle.
Safety Instrumented Function (SIF) Registry Creation
Building structured inventories of all critical safety loops, including specific trigger thresholds and actions.
Quantitative SIL Verification via exSILentia software
Modeling system safety loops to mathematically calculate and prove targeted risk-reduction targets.
Probability of Failure on Demand (PFD) Math Profiles
Calculating error rates based on device testing schedules, vote configurations (1oo1, 1oo2, 2oo3), and component wear statistics.
Safety Requirement Specification (SRS) Documentation
Developing foundational design and testing guides for safety hardware and software logic.
Independent Review of PHA, HAZOP, and LOPA Reports
Auditing existing process hazard documents to confirm all safety assumptions are fully accurate.
Safety Cause-and-Effect Logical Validation Sheets
Verifying that emergency shutdown systems actuate correctly based on process interlock requirements.
