Panorama

Goldcorp's Minera Peñasquito mine has assigned Siemens to service the gearless drive systems of two ore mills, initially for a period of one year. The contract, which also involves maintenance of the associated power systems, will help the mine to increase the availability and reliability of its mills and to minimise downtime.

Peñasquito operates two 11m semi-autogenous grinding (SAG) mills to grind the ore, each with a power rating of 19.3MW and fitted with Siemens gearless drive systems. Siemens is handling all the maintenance work for the drive systems and the associated power systems, including the primary high-voltage supply and the complete medium and low-voltage distribution. This involves preventive and condition-based maintenance, repairs and spare parts management.

Remote diagnostic and maintenance tools make monitoring the plant easier. A stand-by service ensures that essential maintenance work is performed quickly. The maintenance contract is in the form of a performance-based agreement with corresponding payment arrangements. To this end, key performance indicators have been defined for important operating parameters, such as availability.
