Emergency Shutdown & Protection Systems
Developing SIL-compliant Safety Instrumented Systems (SIS), fail-safe safety PLCs, and emergency valve overrides.
SIS Engineering & SIL Verification
Emergency shutdown architectures are kept physically independent from main automation layouts. We design SIS schemes matching SIL criteria for hazardous operations.
- Performing risk analysis and identifying target SIL1 to SIL3 criteria.
- Designing isolated cable pathways and redundant sensor instrumentation.
- Selecting safety-certified controllers (Safety PLCs) with diagnostic coverages.
ESD Pumping & Valve Interlocking
Safety logic must isolate hazardous fluids instantly during process alarms. We program gas detection safety loops and emergency valve interfaces.
- Coding vote-based redundancy algorithms (2oo3 logic blocks) in safety code.
- Terminating toxic gas monitors, flame detectors, and manual ESD buttons.
- Commissioning quick-acting emergency shutdown valves (ESD valves).
