- Hi I am looking into the existing Vib Analysis program that we have in place and was wondering if there is a good method / process available to review and justify why the equipment should stay on it and should we add others to it??
Thanks

Matt

Matt,

Our machine criticality to process and down time cost are the parameters that we use. Also if you have duplicate or should I say backup equipment.I am adding more equipment than what I am removing to my routes.

Best Regards, Dave Dane

Hi Matt;

OEM specifications, and machine criticality are very important, plus past failures need to be taken into account when deciding what needs to be dropped off the list.
As Dave has said, we also have been adding more equipment to our vibration list, after speaking with our strategist group.

Willow,
The equipments can be classified in different categories, A,B,C. Many nuclear stations calssify the equipment in that waay. Class A is for ensuring safety and reliability of reactor and its core cooling. Class B components are essential for power production.Class C equipments will have little or no impact on the plant safety or production. All equipments need not be watched. For example, Calss C equipments are generally run on run to failure theory without any condition monitoring programme for them. Class A equipments are the most guarded ones with respect to frequency of monitoring and concurrent use of several technologies for monitoring and so on.I think it is better to monitor critical equipments rather than unimportant equipments. May think on these lines for decision regarding your equipments.

Willow,

I think we should select the equipment list to be under vibration monitoring based on the relevant ISO vibration standards. The cut off is 15 kW below which is not included but as users we should decide whether to monitor those eqpt depending on site specific factors such as cost to repair or replace them.
