Josh, for guidance on assessing vibration severity, of course those standards are a valuable resource. But, ISO 13379 is not specific to any specific CM/PdM technology, It gives generic guidance and information to help apply any and all types.

Such standards in my view are a valuable consolidation of experience, and should not be looked on as something only to be used with insurance in mind, or to beat an OEM with!

Ok, I will try to get the ISO13379. Were you involved in its development?

I have not looked at those standards with insurance in mind nor to beat the OEM.

My point is that in some instances the insurance agent appears to dictate our maintenance/overhaul practices such as following the OEM fixed time overhaul program with an OEM representative must be present to supervise the job. The insurance agent thinks that the presence of the OEM rep indicates that competent personnel has done the overhaul job. Capital or insurance spares must also be purchased from the OEM as a proof of genuine spare parts. So we have to continue spending and engaging the OEM for these purposes. Is this the best way for reliability and lifecycle cost?

If the above is the case, we couldn't follow your recommended thermodynamic methods and other condition monitoring techniques to determine pump and other rotating equipment overhauls.

I guess my general question is how much can insurance requirements influence our maintenance practices? I would to hear how others handle this kind of issue, if there are any better practices.

Good Point

I believe that not all insurance companies follow that practice. A speaker from the insurance industry (the world's biggest company in fact) at ICOMS2006/World Congress of Asset Management gave the opposite view. I will try and see if his paper can be accessed.

The paper was a keynote address by Ian Barnard, and is included on the CD of the papers from the 2006 conference. The CD can be bought from the Asset Management Council: email Tina.Grenfell@amcouncil.com.au to buy one.

Lots of interesting papers were presented, so the CD has much more value than this one paper alone.

I have just found that paper is also published in Asset Management and Maimtenance Journal. January 2007. Email AMMJ and ask if you can read it online. "Asset management- an insurance perspective" by Ian Barnard, Senior Risk Management Engineer, American International Group.
