Asset Integrity Management: Safety Instrumented Systems Lifecycle Management and Digitalization
The term Asset* refers to a process/facility involved in the use, storage, manufacturing, handling or transport of chemicals. It also refers to the equipment, such as vessels, piping systems, controls, safety systems, utilities, structures and other elements comprising such a process/facility.
Asset Integrity Management* (AIM) is a management system for ensuring the integrity of assets throughout the life cycle of the assets.
Asset Integrity* refers to the condition of an asset that is properly designed and installed in accordance with specifications and remains fit for purpose.
The KP3** report defined asset integrity as ‘…the ability of an asset to perform its required functions effectively and efficiently whilst protecting health, safety and the environment‘.
In the context of ensuring continuing safe operations of process plants, it is crucial to sustainably maintain the Safety Integrity of the SIS layer over the operating life of the installation.
This paper explores the position of Safety Instrumented Systems in the context of Asset Integrity Management for process plants and industry trends in follow ups of SIS into the operate-maintain phase, digitalization of SIS lifecycle management.
