DIN EN ISO 13628-14:2011-12

This part of the International Standard ISO 13628 series addresses the requirements for the use of high integrity pressure protection systems (HIPPS) for subsea applications. ISO 10418, IEC 61508, and IEC 61511 specify the requirements for onshore, topsides, and subsea safety instrumented systems (SIS´s) and are applicable to HIPPS, which are designed to autonomously isolate downstream facilities from overpressure situations. This International Standard integrates these requirements to address the specific needs of subsea production. These requirements cover the HIPPS pressure sensors, logic solver, shutdown valves, and ancillary devices including testing, communications, and monitoring subsystems.
