I work in an industrial facility and have become well versed in the value of preventive and predictive maintance. Preventive is simply a schedule of maintenance or inspection
tasks you complete to head
off failures that would be costly in either money
, time or most important, safety
I am planning on putting together a spreadsheet for my boat. I think the best starting place is walking thorugh the boat and listing all of the systems. These would include rigging
, etc. Then, use a combination of manuals, Calders books, other system owners to list the items to be checked for each system. Make sure you list the interval as well.
You can use this to put together a book with check lists for each system. Then make a master list for each of the check lists and put the date it is next due. If it is weekly, and you just did the PM, then put the next date it will be due on your master list. Then you just have to scan the list once a week, pull out the check lists for the systems due, and complete the work. File the completed check lists. Some PMs are not given by calender time, but by operating time, such as an oil change
at a certain engine
time. For these, you need a review list to check once a week and see if you are at the trigger point.
Every time a failure occurs, try to understand what was the root cause of the failure, then figure a way you might have prevented it with a new or more frequent PM or inspection
. Then add this to your list/book.
Some failures are predictive in nature, such as a water
filter. When the back pressure hits a certain, point you change the filter. Add these to your "operating time" review list.
I know this can seem like a big pain in the butt, but industry has learned that frequent planned maintenance is much less costly than unplanned maintenance.
After collecting some of these sheets
, you can use them to budget
your maintenance and stock spares based on your future travel plans.
