HIPPS System

HIPPS (High Integrity Pressure Protection System) is an independent SIS (Safety Instrumented System) designed to protect downstream lines and plant portion from overpressure events.

It is normally used to replace partially or completely the flare and relief system as a result of an increased environmental awareness.

HIPPS is the ultimate and independent safety layer of a plant on prevention of dramatic event.

The HIPPS system consists of at least three elements: initiators, logic solver and final elements. The main standards applicable to HIPPS are IEC 61508 and IEC 61511.​
