Ensuring Safer Operations with ISA84/IEC61511 Compliant Safety Instrumented Systems (SIS)

Industrial processes present hazardous risks that can threaten the safety of employees and the surrounding environment. These exposures also present unwanted risk to processing assets and equipment that, if not properly mitigated, can result in costly or even catastrophic accidents within operating facilities. That’s why implementing Safety Instrumented Systems (SIS) is a vital safeguard for critical operations. 

Mangan’s focus for decades has been to work with our clients to design and implement ISA84 compliant Safety Instrumented Systems (SIS) that adequately mitigate these unwanted risks to an acceptable level. This includes participating in the HAZOP/LOPA process or review of Prescriptive standards to properly allocate, design, implement, and maintain Safety Instrumented Functions (SIF) to return the process to a “Safe State” when a hazardous condition is detected. We also support Compliance Consulting for Refineries to ensure all regulatory and industry standards are met. 

Through online and offline proof testing and LOPA revalidation processes, Mangan works to ensure the reliability of these systems is maintained per design—an essential aspect of delivering reliable Safety Instrumented Systems (SIS) for Oil & Gas facilities.
