Interesting article about using condition based monitoring to schedule maintenance rather than running hours or the calendar.
Includes an estimate that the average ship requires 24 Engineers to do all the planned maintenance! I would like to see that in the minimum manning schedule!!! ( I know, min manning is calculated on a run only basis with no allowance for Maintenance or cargo work.)
Personally I have been on many ships that at one time had started doing vibration analysis and then stopped.
My present company is very keen on it and we are supposed to take readings of most of the machinery on a running hours basis which can mean 3 or 4 times a month then send the reading for analysis, however the analysis company are only paid to analyse one set of readings per month, so they ignore most of the readings we send in. Some of their results are weird, they keep telling us that the Alternator on the Harbour Generator is out of line with the engine, but this is a close coupled Alternator that is bolted directly to the engine and has no other form of support!
I don't have a lot of faith myself, I think there are too many variables in using a hand held analyser on felt tip pen marks on the machinery.
What do other people think?
It is always better to ask a stupid question than to do a stupid thing.
