A HIPPS is a High-integrity pressure protection system. This is an independent instrumental protection that prevents overpressure in a system. Often a HIPPS must meet the requirements of SIL 2 or SIL 3.
A SIL verification must be carried out for each HIPPS, in accordance with IEC 61511 and IEC 61508 standards. Hereby the following items are verified:
It is highly recommended to make taylor-made test procedures during design phase.
Consiltant BV carries out many HIPPS design verifications for Mokveld, among others.
Voor ieder afzonderlijk SIL 1/2/3 of 4 beveiliging dient het onderstaande uitgevoerd te worden, in overeenstemming met de IEC 61511 of de IEC 61508 normen:
Het is wijs om tijdens het ontwerp van de instrumentele beveiliging al na te denken hoe deze getest dient te worden.
