Case Study
Supply chain and maintenance services in Mongolia
At Ukhaa Khudag (UHG) mine in Mongolia, Thiess’ maintenance capability achieves high fleet availability and optimises component lifecycle costs. Our fleet operates at an average availability of 92%, exceeding industry benchmarks, with machines running an average of 52,000 SMU hours.
Our tyre management program delivers strong results, with 992 loader tyres averaging 25,195 hours and dump truck tyres reaching 12,194 hours. Our welding team has achieved industry-first milestones, including the first-ever R 996 boom foot replacement, working closely with Liebherr, reducing costs by 78% compared to a new boom.
Case Study
Reducing emissions with idle management
When compared with the first ten months of 2024, this Australian project achieved a reduction of 10,444 engine idle hours from January to October 2025, which equates to approximately 706,000L of diesel and 1,912 tonnes of CO2 saved.
Pit Companion enabled fleet controllers to take corrective action to eliminate unproductive engine-on hours thereby reducing emissions. The battery electric system allows operation of air-conditioning and critical electric functions with the engine off, allowing operators to shut down units when not engaged in productive work. Once the machine restarts, the system disengages to allow the battery to recharge in preparation for the next idle cycle.
