The High Integrity Pressure Protection Systems (HIPPS) is a mechanical and electrical system designed to protect downstream lines and plant portion from overpressure events and reduce the chance that the system pressure will exceed the tolerable allowable pressure. HIPPS is the ultimate and independent safety layer of a plant on prevention of dramatic even and protection against over-pressure is obtained by quickly isolating the source causing the overpressure.
The complete typical HIPPS is composed by the following subsystems :
- Initiators
- Logic solver
- Final Element
