PAMA partners with McLaren Applied to expedite its decarbonisation process

From lithium and cobalt for electric vehicle batteries, to bauxite and cadmium for solar panels, mining will play an integral role in securing the resources needed to transform society. It is therefore critical that the mining industry itself is equipped with the tools to decarbonise as rapidly as possible, allowing it to lead the way in enabling a more sustainable future for everyone.

To that end, PT Pamapersada Nusantara (PAMA), one of Indonesia’s largest mining contractors, has partnered with British technology and engineering company, McLaren Applied, to immediately expedite the process of decarbonising its operations.

With fuel representing 25 – 30% of a mine’s operating expenses, any gain in efficiency can have a large impact on pollution, productivity, and costs. Such gains are hard won, with PAMA haul trucks capable of carrying around 100 t of mined material over steep, uneven ground operating in a dynamic environment which requires constant analysis. Ever-changing variables – such as payload, weather, terrain, and route – all affect the driving technique required to ensure maximum efficiency.

While the widespread introduction of electrified or hydrogen-powered mining trucks remains some way off, the application of accurate, real-time fuel analytics can represent a cost-effective way to make an instant impact on both consumption and emissions, increasing efficiency and accelerating decarbonisation.

McLaren Applied's Formula 1-derived technology collects detailed live data from multiple sensors onboard PAMA’s fleet of mining trucks, transmitting it to cloud-based servers and using it to inform a powerful machine learning-based algorithm.

The Fuel Analytics Service references the data received against a full digital model of the mine, using specially developed AI tools to instantaneously calculate what changes the driver should make to optimise fuel efficiency.

Learning from the behaviours of the most efficient drivers over the last three-days’ worth of data, the model instructs vehicle operators in real time, offering live feedback to ensure optimal driving, maximising efficiency and minimising fuel consumption in any conditions. With different drivers’ styles better suited to various aspects of the dynamically changing environment, the most efficient among them may not always be the same, providing all employees with an opportunity to learn and improve.

The latest information is used to regularly re-train the model, providing optimised recommendations for each new driving shift. The compound effect of this feedback loop means that individual drivers that follow the recommendations become more efficient. This, in turn, helps the F1-derived algorithm to teach the entire group to match their improved results, enabling further efficiency increases and extracting maximum driving performance, just as is the case for their counterparts at the pinnacle of motorsport.

What is more, only those drivers objectively analysed to be performing less efficiently require manual intervention from mangers, saving time and money by allowing better-performing employees to continue working while lower performers benefit from more focussed training.

Since implementing McLaren Applied’s Fuel Analytics Service on the trucks at its MTBU mine, data has shown fuel savings of up to 4.5% across the selected cycles or routes versus a control group of drivers not yet using the system. Extrapolated across the total fuel required to operate PAMA’s mining operations each year, the potential for immediate and impactful efficiency gains is clear.

When examined more granularly, the top 25% of PAMA’s drivers using Fuel Analytics were found to save up to 6.5% in fuel and carbon emissions, while simultaneously improving their cycle time by 5.6% as well. This remarkable improvement in productivity in particular, achieved thanks to the Fuel Analytic Service’s real-time recommendations, demonstrates how smoother, more consistent inputs can reduce braking and acceleration, benefitting both speed and efficiency. Through further training and familiarisation, these drivers could realise even greater gains, while their colleagues could also reach similar levels of improvement.

The efficiency gains seen to date can be further linked to key secondary benefits. Reduced maintenance requirements and costs, thanks to decreased wear and tear on the mechanical components of the heavy trucks due to smoother, less frequent inputs, will lead to long-term positive financial and operational outcomes.

Nine months after the introduction of the Fuel Analytics Service, PAMA is in the process of expanding its use to a second site. The technology will remain applicable even once the electric and/or hydrogen trucks enter service, with the gains in efficiency offered by the service continuing to offer cost, productivity and efficiency improvements for years to come.

Pak Hendra Hutahean, Vice President Director at PAMA, said: “The immediate impact of McLaren Applied’s Fuel Analytics Service has helped to improve both the productivity and efficiency of our operations. We are delighted with the results so far and look forward to implementing the technology across further sites once the expected performance at the second site is proven.”
