I'd to know Inspection activity that I was generated to Maintenance guy every month, Is it Condition based monitoing strategy, right? because I wish to summary manhour for the report shown distribution spent manhour for each work type.

If I understand you question correctly you are asking how to categorize inspections. We categorize visual inspections as PM (preventive maintenance). Infrared, ultrasonic inspections are categorized as PdM (Predictive Maintenance)

Hope that helps.

Yes! That's actually my question! So, sum of it, If inspection without tools might called "Preventive" and with tools might called "Predictive"....Is it correct?

I'm not sure I agree with the categorization expressed. Human senses are doing the same thing as the IR camera, vibration monitor or ultra-sonic device; only the human senses are not as sensitive as the predictive tools.

My thinking is a preventive maintenance requires intervention in the equipment, where predictive does not.

J-

What is your objective to categorize inspection activities?

Do you want to categorize them into corrective, preventive, predictive like for maintenance?

Corrective insp is to check something after failure.

Preventive insp is to check something before failure.

Predictive insp is to check something after onset of failure.

My objective as above and yes! I want to categorize our manpower spent for work type.

I don't understand you said, "PdM is to check something after onset of failure"....What that mean?

Panuphan,

In Moubray's book RCM, he categorized On Condition Techniues as follows :

1) Condition monitoring techniques which include the use of specialized equipment to monitor the condition of the equipment

2) Techniques based on variations on product quality

3) Primary effectgs monitoring which entails the intelligent use of existing gauges and process monitoring equipments

4) Inspection techniques based on the human senses.

Hence, if you are performing some inspection which aims to check the condition of the equipment either through NDT instruments or the use of gauges and human senses, I will categorize them as On-Condition Tasks.

My Warm Regards,

Panuphan, pls refer to Vee's book to understand the start (onset) point of failure.

At our plant we have two inspection group. One group deals with rotating machineries (takes vib reading, lube check, etc) and the other with fixed equipment usch as piping, heat exchangers, boilers, storage tanks etc that basically takes care of the plants NDE requirements.

The rotating inspectors report to the Maintenance Reliability and the NDE reports to Engineering. Entry to the SAP related to the machinery condition is bit limited . In few motnhs, the Meridium will be rollout and hopefully provide a tool to the engineers to further improve the equipment reliability at the plant.
