Understanding SIS Turnaround (TAR) Support
Turnaround (TAR) support for Safety Instrumented Systems (SIS) involves planned maintenance, testing, and system upgrades to ensure continued reliability and compliance with safety standards.
Key SIS TAR Support Activities
- Pre-TAR Planning: Identifies SIS components requiring inspection, testing, or replacement.
- System Testing and Validation: Conducts proof testing, SIL verification, and functional safety assessments.
- Instrumentation and Sensor Calibration: Ensures SIS sensors and actuators maintain accuracy.
- Software and Logic Updates: Reviews and updates SIS logic programming and safety interlocks.
- Post-TAR Documentation: Compiles test reports, compliance records, and SIS performance evaluations.
Where Is SIS TAR Support Most Critical?
- Refineries – Conducting shutdown and safety inspections.
- Chemical Plants – Ensuring continued safe operation of SIS components.
- Power Plants – Maintaining functional safety in critical protection systems.
- Manufacturing – Preventing failures in automated process safety systems.
