SIS Field Services
Mangan provides comprehensive Field Services for the startup and operation of Safety Instrumented Systems (SIS). With decades of experience in execution, testing, and revalidation, our SIS team integrates Project-Operations-Maintenance expertise into the development of Start-up, Testing, and Maintenance procedures. We collaborate closely with Industrial Owners to align our extensive experience with their specific needs, ensuring a safe, reliable, and efficient operational environment, including SIS Field Testing Support to guarantee system performance in real operational settings.
Enhanced Safety
Performing maintenance and testing as per design requirements ensures SIS components function correctly, reducing the risk of accidents and protecting personnel and equipment. Our SIS Field Testing Support ensures these components are validated under actual field conditions.
Regulatory Compliance
IEC 61511 mandates that proof testing is conducted on a schedule that maintains the designed Safety Integrity Level (SIL) of each Safety Instrumented Function (SIF).
03
Operational Reliability
By ensuring that SIS are properly installed, maintained, and upgraded, these services minimize downtime and improve overall process reliability. Our SIS Field Testing Support further enhances operational reliability by confirming system integrity during field operations.
04
Cost Savings
Savings starts with the initial SIF allocation, design and development of Proof Test Procedures that optimize the testing requirements (personnel, time) impacting TAR. This can be further enhanced through online/offline and pre-TAR testing strategies. Preventive maintenance and timely upgrades can reduce the likelihood of costly emergency repairs and unplanned shutdowns.
Our services range from providing Start-up and commissioning support to execution of Proof Test Procedures per-TAR and during Turnarounds, including dedicated SIS Field Testing Support to ensure seamless integration and operation.
