Quelles sont les meilleures pratiques et normes en matière de surveillance conditionnelle dans votre industrie ou secteur?

For greenfield projects, a criticality matrix is crucial to set failure modes of assets and detect them using condition monitoring techniques, while the PF curve determines proper measurement intervals. For brownfield plants, follow existing best practices for critical assets to maintain consistent data flow and avoid disruptions. After collecting sufficient data, optimize by aligning resources with site activities. ISO-14224 is a good starting point for reliability data collection when setting up asset hierarchies in condition monitoring software (vibration, thermography, oil analysis, etc.).

In most plants, fault diagnostics could be an easy process especially with proper team competency. However, prognostics process needs some good data to represent the historical records for assets to estimate the RUL (remaining useful life) for assets using statistical methods. For early-stage condition monitoring program development, industrial standards such as ISO-13379 for Diagnostics and Data Interpretation and ISO-13381 for Prognostics, may be used as general guidelines for both processes. It provides a typical workflow and reporting scheme for diagnostics and prognostics that may be optimized with actual site operations.

While the objective of both diagnostics and prognostics is to find the best solutions for assets in terms of maintenance action to maximize the asset uptime. The real challenge is the competency and experience in maintenance and asset operation activities. The decision-making process for an asset requires some synergy between asset owner and other stakeholders to consider the best maintenance action that will be implemented after doing a condition monitoring activity.

Mobius Institute is another well-known company in my area that provides condition monitoring training and certificates. I was lucky enough to attend their African One-Day Training this year. It was a unique experience and an incredible professional growth and networking opportunity.

While certification standards and exams (such as ISO-18436 for vibration Analysts) provide a baseline Body of Knowledge (BOK) necessary for certain job roles, it’s important to recognize that this only represents the minimum required knowledge. True competency comes from experience, developed through the integration of Knowledge, Skills, and Attitude or Mindset. Therefore, we should prioritize not only the quantity and type of training but also the quality and practical application of that training in real-world scenarios.

Implementing the best practices for condition monitoring activity needs a proper reliability culture for the whole organization. The effort put to develop a world class condition monitoring program will be reflected in asset reliability data and organization production outputs. There is no one solution fits all purposes. Condition monitoring techniques are just technologies that reveals some gaps in failure detection methods to be mitigated or avoided in the future. It is a live learning journey through data.

In condition monitoring the widely accepted standard is first, acquisition of the asset knowledge to be measured. Then, the measurement. From measurement, feature extraction or the parameters of the asset which defined its status, is derived, the most difficult part. Next, comparison with the limits and evaluating the changes to be done. After-that optimize LCC, and do the risk-based RAMS in order to make the decision on the maintenance action.
