Repairs and Spares ― Part 1
Having the right spare part on hand when it's needed for a repair seems like a great idea at the time. However, if you consider the number of parts that can fail in your plant, then having every conceivable spare on hand is expensive. And even if you do have it, that spare may be no good due to corrosion or other damage that occurred during storage.
Companies carry insurance against unlikely events, such as a fire. Having an insurance policy with a third party is one form of insurance. Having spare parts is another form, and that form is called embedded insurance.
When determining how much insurance coverage is adequate, you consider the likelihood the event will occur and the magnitude and cost of the event if it does occur. You need to apply this same analysis to spare parts.
Carrying $50,000 in spares for minor events that each might happen once in 800 years makes no sense. Yet, this is standard policy throughout the manufacturing and process industries. Fixing the cause of failure eliminates this cost permanently.
