Predictive maintenance, which incorporates condition based maintenance, is a vitally important technical approach to the maintenance of rotating and reciprocating machines. Sadly, however, many organizations never manage to achieve high performance in this field because they are not able to deal with the complexities associated with the most powerful and important condition-based maintenance technique, which is vibration monitoring.

Vibration monitoring and analysis is still seen by many engineers as less than mainstream. It has a mixed reputation in terms of its capabilities and usefulness, and there are also many false rumours associated with its applicability (or otherwise). Yet, if vibration monitoring and analysis is properly understood and implemented, it offers the opportunity to make very significant improvements in plant reliability. It is arguably the single largest missed opportunity in typical technical maintenance systems.

The programme also addresses the closely related subject of balancing of rotating machinery. Whether it is needed as a corrective action or during the (re-)installation of a machine, achieving high quality balance is vitally important to the long term reliability and overall lifetime of plant.

• This is a specialist analytical programme that is designed for those wishing to become specialists in vibration aspects of technical maintenance and also for those wishing to use vibration approaches in the balancing of rotating plant
• The programme involves extensive data analysis and signal processing methods, and delegates hence need to be computer literate and must have technical backgrounds in an engineering subject. It is highly recommended to Maintenance Engineers, Installation and Commissioning Engineers, and anyone intending to specialize in the application and / or implementation of vibration-based methods
