Improved wrench time for a mining customer

Challenge

Low Overall Craft

Efficiency

The customer, an international blue-chip company in the mining industry and owner of several mines worldwide, needed to achieve a competitive cost per ton copper produced entailing improved efficiency in its full value chain. When Quant was awarded a new extended contract for maintenance for part of the mine, the Overall Craft Efficiency (OCE) was low with a wrench time around 43 percent, which is above industry average of 35 percent, but far from the client’s expectations of an average wrench time above 50 percent for maintenance services.

Results achieved

Higher availability

of assets

Quant and the customer have achieved agreed objectives for efficiency improvements over a four years period; Wrench time improved from 43 percent to 49 percent, yielding higher availability of assets supporting further productivity improvements, and cumulative time savings equal 98,000 working hours over four years.
