The 500th Cummins engine will enter service at the massive Grasberg mining operations in Papua, Indonesia, in 2013.

No one mine in the world has as much mobile machinery as Grasberg. At the beginning of 2013, over 450 Cummins engines were in service at Freeport-McMoRan’s mine and port operations.

Built at an oxygen-depleted altitude of 4,285 metres (14,000 ft), Grasberg is a spectacular feat of engineering. It is the world’s largest copper and gold mine in terms of reserves, and its operations are on a scale unique even by the standards of modern mega-mining.

While the spectacular open pit dominates the landscape, one of the world’s largest underground mining operations is also part of the Grasberg complex. Production from the underground ore bodies, which are beneath and adjacent to the Grasberg open pit, are expected to ramp up over several years to around 240,000 tonnes a day.

Field testing of the biggest generator set ever developed by Cummins will begin at an Australian mine site later this year.

The 3.5 MW C3000-series generator set incorporates Cummins’ new QSK95 engine, a 95-litre V16 that achieves higher output from 16 cylinders than competitors’ 20-cylinder engines.

With an output of over 4000 hp, the QSK95 is the highest horsepower engine ever developed by Cummins.

The C3000-series marks the start of a new line of diesel and gas generator sets from Cummins.

A high-speed diesel (1200 to 1800 rpm), the QSK95 will eventually become available for a range of high-hour, high-load applications including power generation, mine trucks and excavators, oil and gas drilling modules, locomotives and marine vessels.
