There are many reasons for modifying machinery. These include predictive replacement of worn assemblies, repairs following faults, or even retrofitting, whereby the machinery is updated to meet current standards. What all these scenarios have in common is that they should be as efficient, time-saving, and predictable as possible in order to keep machine downtimes and disruptions to operational processes to a minimum.

Servicing strategies such as preventive maintenance, condition-based maintenance, predictive maintenance, or reliability-centered maintenance give the company flexibility in how they schedule any required maintenance, which means there are as few disruptions to operations as possible.
The key is to identify emerging defects in good time in order to leave a time window in which the parts can be replaced before the defect actually arises. This can then be scheduled for a point in time when the affected machinery is not required or is being refitted. With this approach, unplanned downtime becomes planned maintenance.
