The True Cost Of an Oil Leak??Hydraulic systems are often considered perennial consumers of oil and in turn, top up fluid is an inherent cost of operating hydraulic equipment. But what is the real cost of one or more minor fluid power leaks? To answer this question, the costs associated with the following factors need to be considered:
Top up FluidTop up fluid should be the most obvious cost of hydraulic system leaks. I say “should be” because many hydraulic equipment users fail to consider the accumulative effect of the cost of one or more slow leaks over time. Consider a piece of hydraulic equipment losing six cubic centimetres of oil per minute. Over 24 hours, the loss is 0.9 litres, which perhaps is not a significant amount. But over a month this equates to 27 litres, and 330 litres over the course of a year. Assuming a fluid cost of £2 per litre, the annual cost is around £660. Clean-upWhere oil leaks occur, there are almost always clean-up costs to consider, which include:
Assuming it costs £30 per week in labour, equipment and consumables to clean the piece of equipment discussed above, the annual clean-up bill totals more than £1560. DisposalI remember when waste oil companies paid for the privilege of emptying waste hydraulic oil tanks. These days, companies must pay for their waste to be discarded. Environmentally acceptable disposal of waste oil and absorbent material containing waste oil costs money. Assuming a transport and disposal cost of £1 per litre, the annual disposal costs attributable to the leakage discussed above amounts to £330. Contaminant IngressWhen oil leaks out, contaminants such as air, particles and water can get in. The costs to consider here include:
SafetyOil leaks regularly pose a safety hazard. Like the costs associated with contaminant ingress, the costs associated with the hazards of oil leaks are difficult to quantify. However, active management of the safety risk posed – for example, more frequent clean-up than may otherwise be necessary – skews this cost to a quantifiable area. The annual cost of oil leaks on this piece of equipment is approximately £2,600 per year in makeup fluid, clean-up and disposal costs. If a facility contains multiple pieces of hydraulic equipment, the accumulative cost over an extended period of time can be significant.
