Shutdown systems, also known as safety instrumented systems (SIS) or emergency shutdown (ESD) systems, are independent automated systems designed to bring a process to a safe state when predetermined hazard levels are detected. Their primary function is to prevent or mitigate the consequences of dangerous process upsets. These systems are crucial in industries with inherently hazardous operations, such as oil and gas, petrochemicals, and chemical processing, where equipment failures or process deviations could lead to catastrophic events like explosions, fires, or toxic releases.
The design of a shutdown system is based on risk assessment and the concept of Safety Integrity
Unlike basic process control systems (BPCS) which aim to maintain normal operating conditions, shutdown systems are
