NDT techniques assist to ensure:

  • Plant and equipment safety
  • Site and personnel safety
  • Compliance with Australian Regulations and Standards
  • Prevention of loss of productivity with unplanned downtime
  • Cost effective savings in simple repairs instead of complicated repairs of equipment replacements

Our NDT services are suitable for any and every stage of a project, from initiation through to ongoing maintenance and support.

Condition Monitoring (CM)

Condition monitoring is a  means of preventing catastrophic failure in critical rotating machinery – such as power generation plant, larger pumps and main arterial conveying systems – and providing the data needed to accurately determine the optimal schedule for maintenance activities on this plant

The steps to a successful condition monitoring management system (CMMS) are:

  • Identify plant and equipment
  • Define and follow a consistent condition assessment and health ranking system
  • Integrate the condition monitoring program into your existing maintenance strategy
  • Reliability Improvement

Rapallo can assist in the development of the site based strategy from the identification of the inspection regime to the implementation and management of this program through a CMM system. We provide a full NATA based NDT suite of services that is essential for the management of material loss in critical vessels and failure analysis. Our inspectors provide a detailed equipment inspection and assessment service for all types of plant including fixed, mobile and classified.

Rapallo has the backup engineering support that is critical for the more detailed analysis as and when required.

There are a variety of technologies that are used as part of a complete plant condition monitoring program, the more common being:
