Improved wrench time for a mining customer


Low Overall Craft


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.
