Across industry, many definitions are used when it comes to the different types of maintenance. It can quickly get confusing when people talk about preventive maintenance, condition-based maintenance, or predictive maintenance but actually have something else in mind than you do. Some people get very excited about these definitions and can spend a lot of time on for example disagreeing with what is and what isn’t preventive maintenance. Let’s not do that, instead, I’ll offer you my view of the different maintenance types and, more importantly, when to use them.
What are the different types of maintenance?
As far as I am concerned terminology is not important. Other than making sure we are talking about the same thing. If what I consider to be condition-based maintenance you call predictive maintenance that doesn’t really matter. As long as we sensibly talk about the underlying principles.
Like, when to use condition-based maintenance. And how to use it.
However, as I’m often asked questions about the different a specific type of maintenance I decided to put a quick overview together. At least, the way I see it:
1) Preventive Maintenance
Corrective maintenance is done before a failure occurs and consists of maintenance types like:
Time-Based Maintenance, Failure Finding Maintenance, Risk-Based Maintenance, Condition Based
Maintenance and Predictive Maintenance.
2 ) Corrective maintenance
Corrective maintenance is done after a failure has occurred either as Deferred Corrective Maintenance or as Emergency Maintenance. In the rest of this article, I will discuss each of these different maintenance types in detail:
In Preventive Maintenance
Time-Based Maintenance (TBM)
When people talk about preventive maintenance (or preventative maintenance) they usually refer to what is better described as...
Risk-Based Maintenance (RBM)
Risk-Based Maintenance (RBM) is when you use a risk assessment methodology to assign your scarce maintenance resources to those assets...
Failure Finding Maintenance (FFM)
Failure Finding Maintenance tasks are aimed at detecting hidden failures typically associated with protective functions...
Condition Based Maintenance (CBM)
Most failure modes are not age-related. However, most failure modes do give some sort of warning that they are in the process of occurring or are about to occur...
Predictive Maintenance (PDM)
Up until recently when people spoke about Predictive Maintenance (PDM) this was essentially as a synonym for Condition Based Maintenance.
Corrective Maintenance
Deferred Corrective Maintenance
Deferred Corrective Maintenance refers to a maintenance activity that is postponed after a fault or failure is identified, rather than being addressed immediately.
Emergency Maintenance
Emergency Maintenance typically leads to longer equipment outages and more production impact. And it is less safe.
