IOGP Report 551

This recommended practice gives guidance in life cycle planning and obsolescence management to maintain integrity, high availability and low life cycle cost automation systems.

An automation system performs safety, control, and/or monitoring functions on oil and gas installations. Automation systems are expected to perform their function throughout the field life. A typical automation system life cycle is around 25 years, while large oil and gas fields are expected to last significantly longer (more than 50 years).

With ever-increasing demand to extend the life of operating assets, the risk of obsolescence has become more prevalent. Obsolescence presents significant concern to the industry, for both new and brownfield projects (maintenance and automation system evolution). The impact of obsolescence is felt when equipment fails and the replacement for the failed component is no longer available, can no longer be satisfactorily supported or can no longer be procured from approved sources. Significant and expensive downtime might take hold whilst the search for new approved sources or alternative solutions continues.

A robust obsolescence management strategy can address and mitigate the risks associated with the obsolescence of equipment. This report defines the proactive Obsolescence Management Process as it applies to automation systems for oil and gas producers and to specify the minimum requirements for automation systems suppliers to manage the risks of obsolescence through activities associated with:

  • prevention
  • prediction
  • resolution

The combination of these tasks should help reduce the risks, costs and impact to the business when components, tooling, suppliers, process and knowledge become obsolete, through the continued management of the equipment life cycle status.

This report is accompanied by two companion documents:

  • Form 551A, Automation System Equipment Component Detail
  • Form 551B, Automation System Equipment Status Overview
