EPC has managed electrical infrastructure projects across BMA operations. Work for BHP also extends to deploying pedestrian detection technology at Western Australia Iron Ore and Copper South Australia (Olympic Dam).
BHP’s project used vision technology powered by artificial intelligence to detect pedestrians around materials handling equipment. EPC managed trials and selection of the preferred system, followed by implementation at both Western Australia Iron Ore and Copper South Australia (Olympic Dam).
At BMA Blackwater Mine, 12 transportable 66 kV/6.6 kV substations received a protection upgrade. The upgrade added 66 kV circuit breakers and integrated arc flash protection, including differential protection. EPC provided electrical project management for the upgrade.
BMA Blackwater’s Thermal Coal Plant needed a new 22 kV substation because the existing installation no longer met Australian and coal-mining standards; the project also included metering-panel replacement and relocation. EPC managed the electrical side and divided the work into packages for metering-related works, switchgear supply and switchgear installation. EPC evaluated tenders, coordinated switchgear offloading and mobilised the electrical contractor for installation.
Five solar-powered boom gates with access controls were designed and installed across BMA Blackwater Mine to minimise light-vehicle traffic on haul roads. EPC provided electrical project management for this work.
Two tramp-iron magnets, each weighing 10 tonnes, were added across the TCV 603 and 607 stacker/reclaimer conveyor belts at BMA Blackwater Mine. EPC led the electrical side of their design and installation.
Mining at BMA Blackwater’s R32 pit required the relocation of existing electrical infrastructure so operations could continue. The project relocated the 66/6.6 kV power lines and Substation 38.
Advancing mining operations at BMA Blackwater Mine reduced the effectiveness of the Ramp 20 communications tower. A new tower was installed to serve the changing operation.
BMA Blackwater Mine’s Wilpeena and Tannyfoil projects involved relocating 66 kV power lines. EPC managed the electrical work on both relocation projects.
Development of the R34 Pit at BMA Blackwater Mine included a new pump station for the CHPP’s main water supply. EPC managed the electrical work for the pump station project.
Bottlenecks in the fines circuit prompted modifications to BMA Saraji’s coal handling and processing plant (CHPP). For Work Pack 4, EPC managed electrical design and installation for several changes to the plant.
An obsolete motor control centre on the pontoon at Rangal Dam prompted an upgrade for BMA Assets and Infrastructure. EPC provided electrical project management for the design and installation of a new containerised pump station as its replacement.
