Some of our most critical Safety Instrumented Systems, e.g. Emergency Shutdown (ESD) and Burner Management Systems (BMS) are based on Triple Modular Redundant (TMR) platforms. These TÜV certified, high-integrity solutions offer continuously safe and reliable production and protection even under duress. The fault tolerant architecture maximises availability, typically to ‘5 nines’, whilst providing safety protection up to SIL 3.
In essence TMRs are designed to maximise process up time whilst protecting operational personnel and the environment from hazardous situations that could occur in the event of a failure.
The continuous and extensive internal diagnostics automatically pinpoint faults and in the unlikely event of an internal failure a faulted CPU, communications or I/O module can be replaced while the system continues to operate.
Projects are managed to comply with IEC 61508 or IEC 61511 using our own Functional Safety Management System (FSMS). Charter Tech’s FSMS has been independently validated by Lloyds ScandPower and several of the world’s leading Oil and Gas producers.
Typical TMR applications:
Emergency Shutdown Systems (ESD)
Burner Management Systems (BMS)
Fire & Gas Systems (F&G)
