Guidelines for standardised classification and failure reporting for safety equipment in the petroleum industry
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, and is a main delivery from the APOS project. Standardised equipment grouping, equipment properties and simplified failure taxonomies are suggested. For future digitalisation, the guideline also identifies standardised equipment properties and associated property values to enable establishment of a complete information model for functional safety. The suggested taxonomies and properties have therefore been compared and mapped against recognised standards and relevant electronic equipment libraries.
Potential for automated follow-up of safety equipment
Essential means to follow up safety-critical equipment are the reporting, classification and analysis of failure data. Experience shows that considerable manual effort is needed to attain high-quality data, and therefore, this report investigates possibilities for automated failure reporting and failure class determination.
Guideline for follow-up of Safety Instrumented Systems (SIS) in the operating phase:
This guideline describes a best practise for follow-up of safety instrumented systems (SIS) during operation of a process facility. It covers management of functional safety, operation, maintenance, monitoring, and management of change. Methods for updating failure rates and optimising test intervals are presented. The document is an update of SINTEFs SIS follow-up guideline published in 2008 and 2021.
Information model for functional safety
The main objective of this activity has been to contribute toward further digitalisation of the petroleum/energy industry, focusing on information modelling for the functional safety domain. As part of this, it is important for the industry to have a common understanding of what should be included in an information model for functional safety and how such a model can be structured and maintained throughout its lifecycle. It is also briefly discussed how a functional safety information model, e.g., for a typical safety instrumented function (SIF), interacts and can be integrated with other disciplines’ information models. This report should be read in conjunction with [link] «Guidelines for standardised classification and failure reporting for safety equipment in the petroleum industry » which further specifies the information elements (properties) and provide mapping towards relevant equipment libraries and standards.
