Recommendation – Blog Series 6

In my previous blog I completed the FMEA and RCM assessment for the “Dewatering Pump” which is a critical equipment in my plant. The final outcome of the assessment is a list of recommendation which the reliability engineer creates and the maintenance planner will plan to execute it in the PMR application.

With this I move forward to the step 4 where the reliability engineer will create a set of recommendation during FMEA or RCM assessment.

Recommendation can be created from four different sources –

  • Instruction – Manufacturer or the Operator would already have instruction with a set of steps using which reliability engineer can create a recommendation. The frequency given in the recommendation is considered in the PMR application by the maintenance planner
  • Placeholder Instruction – It is possible that there is no detailed instruction available in the system and reliability engineer would create a placeholder instruction.
  • Imported Task list (Maintenance Plan) – If a SAP PM system is connected with the ASPM system, then all the related task list with maintenance plan is replicated to ASPM system. The same information is also available in the context information.
  • Imported Task list – If a SAP PM system is connected with the ASPM system, then all the task list which is not assigned to a maintenance plan is replicated to ASPM system. The same information is also available in the context information.

For the RCM assessment of “Dewatering pump”, based on the Function, Functional Failure, Failure Modes & Effect, as a reliability engineer i want to propose two recommendation –

  • Preventive – As the name suggests, it defines the recommendation which will help prevent a failure.
    • Time Based – This recommendation has frequency based on time. Only single frequency is allowed
    • Performance/Condition Based – This recommendation is based on an indicator which is available at the asset. Multiple frequency is allowed with a “AND”/”OR” operator.
  • Corrective – As the name suggests, it defines the recommendation which will corrects a failure which has already happened.
    • Planned – Some times corrective measure are planned activities which you would do it at a frequency.
    • Unplanned – This recommendation are complete breakdown scenario in which you cannot plan the frequency. If a breakdown happens, this set of recommendation needs to be preformed.

I will create the recommendation based out of placeholder instruction as a corrective-unplanned as it is breakdown scenario and as a reliability engineer i cannot predict the frequency.

Here on, the recommendation execution part is handed over to maintenance planner who will take a conscious decision on which recommendation should be implemented. Various factors are taken into consideration here like estimated cost, frequency, remaining risk etc.

In my next blog, I will give the overview of how a maintenance planner would take the recommendation forward.
