There are scenarios of asset condition monitoring that can be implemented by the meters and triggers available in Calem Enterprise. Here is such a sample case:
I will use this case to demonstrate the steps to set up Calem for auto-monitoring the engine oil analysis results and generate work orders for engine oil replacement.
Step 1. Asset Structure
In this case a vessel is modeled as a top level asset. The main engines in the port side and starboard are modeled as child assets of the vessel asset. Modeling engines as assets allows one to take advantage of many features for assets in Calem.
Step 2. Meters, Meter Groups and Triggers
Assets and locations in Calem can have meters. A meter can be a physical meter such as an odometer of a car. It can also be a virtual one which represent a measurement of an aspect of an asset at a time. For instance, in the case above, the engine operational hours can be a physical meter. An engine oil analysis may yield 8 results. Each result can be modeled as a virtual meter for a given asset. Before a meter can be created, let's take a look at meter groups where you can define common triggers for a measurement.
A meter group represents identical meters. So, each distinctive measurement is modeled as a meter group. For example, the temperature of port and starboard engines can be modeled as two engine temperature meters, one for port, one for starboard. A meter group of main engine temperature can be defined for the main engine temperature meters.
A meter group can have reading triggers. For instance, when main engine temperature is overheated a repair work order should be generated. A meter trigger can be defined as temperature over a certain degree. The following is a screenshot of the meter trigger creation:
When creating meter groups reading types should be set properly. There are four reading types. See User Guide for more information about reading types.
Finally, one may create meters for the engine assets with their meter groups define above.
Step 3. PM Plans and PMs for Meter Triggers
Meter triggers are fired when readings are added, Calem will search for PMs that include the triggers fired. If a PM is found, the PM is generated as a work order. If not found, a corrective work order is created for the meter trigger.
For our case above, it is better to create a PM Plan and PM for oil change:
Step 4. PM Plans and PMs for Oil Analysis
Next step is to define PM Plans and PMs to perform oil analysis based on meter readings such as every 100 hours of engine odometer.
Step 5. Taking Meter Readings
You may configure quick meter reading entry to make meter reading entry easier. See this blog about quick meter entry.
That is all to set up for asset condition monitoring.
