Guidelines for standardised classification and failure reporting for safety equipment in the petroleum industry, Ver 04

This document provides guidance on how to report and classify failure and maintenance data for safety equipment, as a basis for improved follow-up and future automation. Standardised equipment grouping, equipment properties and simplified failure taxonomies are suggested. Focus is on safety instrumented systems (SIS) but selected non-instrumented safety critical equipment types are also covered. As part of future digitalisation, establishing a standardised information model for functional safety and safety instrumented function (SIF) follow-up will be an important prerequisite. A main objective with this guideline is to contribute towards such a model, by identifying standardised equipment properties and associated property values. The suggested taxonomies and properties have therefore been compared and mapped against recognised standards and relevant electronic equipment libraries.
