CROSS-BORDER OPERATIONS Racheal Njoroge, director: Operations, Cummins Southern Africa, highlights the revived push for growth and diversification in four key markets in 2018 – oil and gas, marine, mining, and automotive. CUMMINS SOUTHERN AFRICA Orlando Ferrao, general manager, Cummins Southern Africa, has aggressive plans in place to form cohesive partnerships with customers to ensure the best experience possible. As part of this roll-out, the company says it will be increasing the availability of over-thecounter parts to improve aftermarket support of its products. MINING SOUTHERN AFRICA The CSARO Mining activity, led by Andre Kuhn, has developed an advanced fault-finding electronic support tool that identifies the origin of technical glitches and the parts required to repair it. This reduces downtime, improves efficiency and provides cost savings for the customer. Furthermore, Cummins' telematics system, DEMS (Data Enabled Mining Solution), remotely monitors the vital statistics and performance of an engine, presenting early warnings of potential engine downtime. POWER GENERATION The Cummins Power Generation activity in Southern Africa, led by Robin Kuriakose, highlights the largest single unit genset, the C3750 powered by a 95 ℓ engine, which is set to be installed and commissioned by mid-2018. This is a first for Southern Africa. DEVELOPMENTS WELL UNDER WAY Substantial business and financial acumen is required to ensure that the developments undertaken by Cummins Southern Africa are a success. The finance team, under Victor Masuku, leader: Finance, make certain that all the company’s numbers add up.

China, India, Japan, Russia, South Africa and the USA are currently the six largest coal consumers, based on IEA 2015 statistics.

WorleyParsons RSA, which has designed more deep mine shafts than any other company in the world, has recently completed the first and most critical phase of Wesizwe’s R10.7 billion Bakubung Platinum Mine project near Rustenburg.

he commissioning of the main and service shafts and the ore-handling system marks a major milestone in the

Bakubung project’s timeline. “The most important phase in developing a deep underground mine with vertical shafts is equipping and commissioning the shafts to hoist – and we have successfully achieved that within the required time frame,” says Ryan Illingworth, project director: Bakubung Platinum Mine, WorleyParsons RSA. He adds that with shaft steelwork, rock skips and man cages installed, and the production and service shafts complete, the vital work has been done and the second phase of developing underground infrastructure can continue. The downcast production shaft, to be used for man and materials, has a hoisting capacity of 250 000 t of ore and 15 000 t of waste per month. A refrigeration system will provide bulk air cooling at a later stage. The layout of the 8.5 m diameter lined production shaft accommodates two 20 t skips, a two-deck cage with 12 t/150-man payload, a counterweight, and 20-man service cage. The 7.5 m diameter lined service shaft currently consists of a stage

rock and materials.

Other highlights Other major milestones WorleyParsons has achieved on this project include the construction of the main shaft terrace, main stores, workshops, temporary offices, sewage treatment plant, main access road and the production shaft headgear. This 83 m tall headgear – for which WorleyParsons RSA received a South African Institute of Steel Construction Award in 2014 in the mining and industrial category – was erected in just 18 days and will be used to service all the conveyances. The three winders are ground-mounted and include a Koepe winder for rock hoisting, and a double drum cage/ counterweight winder for men and material hoisting.

A bespoke solution A significant optimisation effort that WorleyParsons RSA achieved during the first phase of the project was the local development and implementation of a cost-effective and highly efficient roping-up system instead of importing a more expensive system. Illingworth explains that, by working in conjunction with the Tech Edge group, WorleyParsons developed the first locally built Koepe roping-up equipment suitable for four ropes simultaneously. This tailor-made equipment included deflection sheaves, a compression

been involved in the project for almost a decade – from pre-feasibility and feasibility stages to being appointed as the engineering, procurement, construction management contractor in 2012. Bakubung Platinum Mine is located in the North West province of South Africa, in the western limb of the Bushveld Complex, and is expected to have a lifespan of 35 years and employ over 3 100 people when full production is reached. The mine will produce 255 000 t per month on steady state for 24 years. Four mining levels are planned, ranging from 690 m to 810 m below collar. Merensky and the UG2 reefs will be mined.

When a major copper mine in Zambia required a 110 kW variable-speed drive (VSD) urgently for a slurry application, it turned to SEWEurodrive South Africa, which was not only able to supply the unit on a fast-track basis over the Christmas 2017 period, but also assisted with the on-site installation and commissioning.

The success of this project not only increases SEW’s installed base in the Zambian Copperbelt itself, but further entrenches the company as a supplier of solutions that make for the lowest total cost of ownership. “For example, we have just sold an additional two gearboxes to the same mining producer, with a further two on order.
