    BHP Olympic Dam LV radiator upgrade: reliability takeaways for mine engineers

    BHP Olympic Dam LV radiator upgrade: reliability takeaways for mine engineers

    First reported on International Mining – News

    30 Second Briefing

    BHP is replacing the radiators across its light vehicle fleet at the Olympic Dam operation in South Australia with Terrain Tamer Heavy Duty pressed aluminium units after an almost 12‑month in‑field trial. The heavy-duty radiators are designed for higher vibration and thermal loads typical of underground and surface mine roads, offering improved cooling performance and resistance to core and tank fatigue compared with standard OEM units. For maintenance teams, the change points to reduced unplanned LV downtime and lower cooling‑system failure risk in high‑dust, high‑ambient conditions.

    Technical Brief

    • BHP’s adoption followed nearly 12 months of in-field reliability and cooling performance data collection.

    Our Take

    BHP’s decision to standardise Terrain Tamer radiators at Olympic Dam aligns with other recent fleet-modernisation moves in our database, such as its battery-electric haul truck trials at Jimblebar, signalling a broader push to harden mobile equipment against heat and duty-cycle stresses rather than only targeting headline decarbonisation wins.

    Almost 12 months of radiator testing at Olympic Dam suggests BHP is applying the same long-cycle validation approach it uses for new haul truck technologies, which typically reduces unplanned downtime but can slow rollout to other Australian sites until reliability data are bankable.

    Techking–Boonray autonomous mining tyres: design and duty-cycle notes for engineers

    Techking is collaborating with Chinese autonomous haulage specialist Boonray to co-develop mining truck tyres tailored to electric and driverless fleets, where high, instantaneous torque and tighter speed control change loading behaviour. The partners are integrating tyre design into early vehicle engineering, using Boonray’s AHS control data on torque curves, duty cycles and haul-road conditions to refine carcass structure, compound selection and heat management. For mine operators, this points to tyre performance being tuned to specific autonomous truck–road systems rather than generic TKPH-based selection.

    EcoPower Mate temporary power: layout and staging insights for mine planners

    EcoPower Mate introduces a modular temporary power system for remote mines, targeting exploration camps, mobile offices, communications nodes and construction facilities that currently rely on diesel gensets. Designed for locations with shifting footprints and variable loads, the units can be redeployed as drilling pads, laydown areas or satellite camps move, reducing the need to oversize fixed generator banks. For mine planners and project engineers, the approach supports more flexible power layouts and staged infrastructure without committing to early grid extensions.

    Sedgman wins Barroso lithium FEED: design and risk notes for project engineers

    Sedgman has secured the Front-End Engineering and Design contract for the lithium concentrator plant at Savannah Resources’ Barroso lithium project in northern Portugal, following its earlier work on the process flowsheet and Definitive Feasibility Study plant design. The FEED scope will refine equipment selection, layout and mass–energy balances for the hard-rock spodumene concentrator, de-risking capital estimates ahead of a final investment decision. For geotechnical and civil teams, the move signals progression towards detailed earthworks, foundations and tailings/waste infrastructure design on what is billed as mainland Europe’s largest lithium project.
