Lifecycle stage

“Equipment selection is important because if you decide to go with an unreliable supplier and later need to replace the equipment you could run into costly challenges should you find that the supply company is no longer operating. For example, when possible, always try to go with industry-standard components rather than bespoke – replacements will be much more readily available. Buy cheap, buy twice.”

Ann Vicens – Product Leader for Centralizers & Asset Life Extension, Claxton


A key enabler for performing proactive and strategic management of the lifecycle of safety and infrastructure-critical products, is the ability to forecast when technologies and parts become unavailable for purchase. Developing methods for forecasting obsolescence can minimise costs and complications later down the line.

Risk-based inspections (RBI) can provide insightful data that can be used as evidence to take a scientific approach to achieve cost-effectiveness rather than leaving it to chance. RBI seeks out the potential of an asset’s failure, providing a ‘risk snapshot’ in time. The risk-based approach has been utilised for some time within refineries, petrochemical and chemical facilities, which have reaped the benefits of significant cost savings. Find out more about implementing RBI in this Claxton blog.

Early intervention, or taking a proactive obsolescence management approach, can include:

  • Considering the issue of obsolescence throughout the project, from initial planning to decommissioning. When evaluating the risks at each stage, obsolescence should be one of the points of discussion.
  • Looking for early warning signs of component discontinuance to allow maximum time to react and avoid being forced to use costly resolutions.
  • Corrective action options at the component level can be taken while low-cost opportunities still exist.
  • Evaluation of end of life notices and part change notifications.

“Proactive, strategic and tactical measures should be taken when planning to minimise future obsolescence of equipment.”

It is important to have a plan of action for when equipment is no longer performing or compatible due to updates to existing infrastructure. Equipment lifecycle management is a process that manages the usage and maintenance of your asset throughout its lifecycle or period of ownership. Equipment total lifecycle management applies to information, operation and maintenance management and integrity information assessment, as shown in an example model below:

Obsolescence management doesn’t just apply to equipment. Operators need to continuously invest in upskilling their workforce to keep them up to date with the latest industry regulations. Gaps in skills and knowledge can result in costly project delays, resource wastage and the worst-case scenario – accidents.

We covered the importance of competency training previously in a Claxton blog with our in-house competency manager, Robert Carlyon.
