Fact: An oil refinery in the Western US achieves a pump mean-time-between-failure (MTBF) of over nine years. The facility has 1,200 pumps and, in a given year, repairs 130 of them. Fact: An oil refinery "elsewhere" has about the same number of pumps installed and does 260 repairs each year; its MTBF is roughly 4.5 years. Including overhead expenses, the average pump repair costs a US refinery $13,000. Each year, the refinery "elsewhere" spends $1.7 million more for pump repairs than the refinery in the West. If one would teach the "elsewhere" oil refinery to safely extend run time and increase pump MTBF to 5.5 years, this facility would save $600,000 per year. If this achievement required
