 Compared to equipment used in hard rock mines, the lifespan of equipment
deployed in oil sands operations tends to be shortened due to the abrasive
nature of the material and soft ground conditions in which it operates. One of
the challenges of oil sands mine planning is to determine the most
cost-effective replacement time for aging equipment. For cost engineers dealing
with aging equipment, the options become an economic trade-off between taking
the chance of higher frame failure or buying new equipment. Therefore, the
ultimate question is: “When is the best time to replace the equipment?”
