    A Cummins gas-fired power station is vital to a new mining project in Western Australia

A Cummins gas-fired power station is vital to a new mining project in Western Australia

On the gas

A new mining project in Western Australia has been a great opportunity for Cummins to showcase its ability to deliver a turnkey power generation solution involving the disciplines of engineering, procurement, construction and project management.

Mt Marion Lithium Project is located around 40 km south-west of Kalgoorlie in the goldfields region of WA and is jointly owned by Mineral Resources Ltd (MRL), China’s largest lithium producer Jiangxi Ganfeng Lithium Co, and Neometals Ltd.

The project was approved for development in October 2010, with major civil constructions beginning in January, 2016. The production of lithium concentrate followed in mid-2016. Mt Marion is the second largest high-grade lithium concentrate mine site in the world, producing lithium which is used mainly in batteries, particularly for electric/hybrid cars.

Design, deliver, commission.

To meet the power requirements of the mine, MRL turned to Cummins to provide a 9 MW high voltage (11 kV) power station. The Mt Marion power station represents the first LNG power generation facility installed and commissioned for MRL, and the first major supply agreement between Cummins and MRL.

“Early in 2016 we were given a clear mandate to design, deliver and commission the 9 MW gas-fired power station for the Mt Marion project,” says Cummins project manager Dallas Gledhill. Cummins quickly assembled its team comprising project managers, engineers, project administrators and field service technicians from Perth and Melbourne.

During the early development phase, Cummins settled on a combination of five lean burn natural gas generators – four QSV91 high-ambient, quad-turbo units rated at 2000 kW,

and one QSK60 rated at 1160 kW. An additional QSV91 is a future option.

Conceptual engineering and design followed, driven by functional requirements, with bi-weekly design reviews transforming the packages from basic enclosures into multi-faceted, interactive […]

The ISXe5 is scoring highly at Curley Cattle Transport.

CATTLE CLASS

Curley Cattle Transport had its origins in Cloncurry, north-west Queensland, in the early 1970s when Mick Curley bought his first truck to pull two stock trailers. He grimaces at the memory of that truck – a Dodge powered by a Cummins C-160, a naturally aspirated 464 cu.in. (7.6-litre) inline six delivering 160 hp at 2800 rpm.

Today, five Signature 600 versions of the 15-litre Cummins ISXe5, generating 600 hp and 2050 lb ft of torque, are the latest additions to the Curley fleet of 30 roadtrain triples. All the prime movers are Kenworth – T650, 658 and 659 models – and all have Cummins Signature power, spanning Gen II, EGR and e5 variants.

Mick Curley’s son Steve is managing director of the business today, although Mick still keeps an eye on proceedings and is obviously proud of a business that has endured in what is still a challenging environment where the demands are obvious – achieving cost-effective life from equipment, maintaining and supporting the equipment in a harsh, remote environment, and attracting and retaining good people.

When asked about the five ISXe5 engines that entered service early in 2016, Steve Curley delivers a laconic response: “I like them.” He says they’ve already done a lot of hard kilometres and are showing a pleasingly high level of reliability.

Dave Pringle… describes the ISXe5 as a “big step up” from previous iterations of the 15-litre Cummins he has driven.

Reduced fuel costs with ISXe5.

Fuel costs, which account for around 25 per cent of Curley’s operational costs, are another factor that have constant focus.

While he points to driver influence as having a major impact on fuel economy, Steve Curley reveals the ISXe5 itself is contributing to reduced fuel costs. “There’s little […]
