It doesn’t get much more remote than this. I’m in inland Western Australia, at Rio Tinto’s Greater Nammuldi iron ore mine.

It’s about a two-hour flight north from Perth in a region called the Pilbara.

No-one lives permanently here. Around 400 workers are on the site at any one time, and they are flown in, working between four and eight days, depending on their shift pattern, before flying home.

Giant trucks the size of townhouses, capable of hauling 300 tonnes, criss-cross red-earth roads in various sections of this open-pit mine complex.

For an outsider like me their size is intimidating enough, but multiplying that feeling is the knowledge that there’s no driver at the wheel.

During a tour of the site in a normal-sized company vehicle, one of the trucks comes into view, approaching from a side road.

I sigh with relief as it deftly turns and continues in the direction we have just come. “Did it make you feel uncomfortable?,” asks the vehicle’s driver Dwane Pallentine, a production superintendent.

Greater Nammuldi has a fleet of more than 50 self-driving trucks that operate independently on pre-defined courses, along with a handful that remain manually driven and work separately in a different part of the mine.

Being trialled is also an autonomous water cart affectionately known as Henry, which, along with manually driven ones, sprays the mine roads to keep the dust down.

The company vehicle I am in is able to operate alongside the autonomous trucks only because it has been fitted with high-accuracy GPS, which allows it to be seen within a virtual system.

Before entering the mine’s gated autonomous zone, we logged onto this system and a controller verified over the radio that we were visible.

It has encased our vehicle in a virtual bubble that the self-driving trucks “see” and which causes them to manage their proximity by slowing or stopping as necessary.

A touch screen in our cabin displays all the staffed and autonomous vehicles and other equipment in the vicinity, along with “permission lines” that show the immediate routes the self-driving trucks are intending to take. Had I looked at the screen instead of fretting I would have seen that truck was going to turn.

In addition to all vehicles being fitted with a big red emergency button that can stop the system, the autonomous trucks have lasers and radars front and rear to detect collision risks.

The sensors also detect obstacles. If a large rock fell off the back of a truck, the sensors on the next truck along would notice it and the vehicle would stop.

However, some trucks seem extra sensitive – on my tour I see a couple foiled simply by rough roads.

Co-ordinating and monitoring these robots is Rio Tinto’s Operations Centre (OC) in Perth, about 1,500km (930 miles) to the south.

It’s the nerve centre for all the company’s Pilbara iron ore operations, which span 17 mines in total, including the three making up Greater Nammuldi.

Guided from here by controllers, include more than 360 self-driving trucks across all the sites (about 84% of the total fleet is automated); a mostly autonomous long-distance rail network to transport the mined ore to port facilities; and nearly 40 autonomous drills. OC staff also remotely control plant and port functions.

Autonomy isn’t new to Rio’s Pilbara operations: introduction began in the late 2000s.

Nor is it unique: Australia has the greatest number of autonomous trucks and other mining equipment of any country, and other mining companies in the Pilbara also use the technology.

But the scale Rio has grown its operations to here, including at Greater Nammuldi – which has one of the largest autonomous truck fleets in the world – gives it global significance.

And it’s a global trend. According to GlobalData the number of self-driving haul trucks worldwide has roughly quadrupled over the past four years to more than 2,000, with most made by either Caterpillar or Komatsu.

The biggest reason for introducing the technology has been to improve the physical safety of the workforce, says Matthew Holcz, the managing director of the company’s Pilbara mines.

Mining is a dangerous occupation: heavy machinery can be unpredictably operated by people who can also become fatigued. “The data clearly shows that, through automation, we’ve got a significantly safer business,” says Mr Holcz.

It has also improved productivity – to the tune of about 15%, he estimates. Autonomous equipment can be used more because there are no gaps due to shift changes or breaks. And autonomous trucks can also go faster when there is less staff-operated equipment on the scene.

Such automation does not come cheap. Rio won’t disclose what it has spent in total on its Pilbara automation journey to date, but observers put it at multiple billions of dollars.

Meanwhile, employment opportunities have evolved. The narrative might be one of robots taking jobs, but that doesn’t seem the case here so far.

While the OC has about one controller for every 25 autonomous trucks – according to Rio, no one has lost their job because of automation.

Instead, there have been redeployments: truck drivers have joined the OC as controllers themselves, been reskilled to operate different pieces of equipment, such as excavators, loaders and dozers, or gone to drive manual trucks at different sites.

On the OC’s large open plan floor, amid the banks of monitors arranged in clusters for the different mines, I meet Jess Cowie who used be a manual driller but now directs autonomous ones from the central drill pod. “I still put holes in the ground…just without the dust, the noise and being away from the family,” she says.

Automation is delivering a “step change” in terms of safety in the mining industry says Robin Burgess-Limerick, a professor at the University of Queensland in Brisbane who studies human factors in mining. But it doesn’t mean there isn’t room for improvement.

Professor Burgess-Limerick has analysed incidents involving autonomous equipment reported to regulators.

As he sees it, the interfaces used by staff both in the field and in control centres to gain information aren’t optimally designed. There have been situations where field staff have lost awareness of the situation, which better screen design may have prevented. “The designers of the technology should put a bit more effort into considering people,” he says.

And there is also a risk that controllers’ workloads can be overwhelming – it is a busy, high stakes job.

Over-trust, where people become so confident the autonomous equipment will stop that they start putting themselves at risk, can also be an issue, and he notes effort needs to be directed into improving the ability of trucks themselves to detect moisture. There have been incidents where wet roadways have caused them to lose traction.

There can be legitimate safety concerns with autonomous equipment, says Shane Roulstone, co-ordinator for the Western Mine Workers Alliance, which represents mining-related workers in the Pilbara.

He points to a serious incident this May where an autonomous train slammed into the back of a broken-down train, which workers at the front end were repairing (they evacuated before it hit but were left shaken).

But Mr Roulstone also praises Rio generally for having, over time, developed “some good strategies, procedures and policies” around how people interact with automated vehicles.

Mr Roulstone expects that at some point options for redeployment will lessen and there will job losses. “It is just the mathematics of it,” he says.

Meanwhile, Rio’s automation journey in the Pilbara continues with more trucks, drills and Henry the water cart. It is also closely watching work by Komatsu and Caterpillar to develop un-staffed excavators, loaders and dozers.

Late in the afternoon, waiting at Greater Nammuldi’s airport for the last flight back to Perth, the announcement comes that it has been cancelled due to an issue with the plane. That’s 150 extra people who will now need to be fed and accommodated. It is nothing for Rio, but I can’t help but think we humans are complicated compared to robots.

Mitsubishi Electric Group company's Climaveneta Climate Technologies aims to be major player in Indian chiller market- The Week

Mitsubishi Electric Group company Climaveneta Climate Technologies (CTT) is set to invest Rs 400 crore in its manufacturing facility near Bengaluru to increase its market share in the Indian chiller market. Though currently its production is predominantly targeted at the Indian market, the company plans to double its capacity by 2030 and scale up exports to nearby regions.

The company presently has an order book of over Rs 500 crore and is targeting to double the annual order intake in the next five years. “Our chiller systems (40 per cent) is dominated by the data centres where the demand for the chiller system is growing phenomenally. Our current capacity from our factory here is around 1,200 chiller systems per annum, but we aim to double it in the near future to 2,400 systems depending on the traction we get. Currently, we employ close to 300 people but plan to take it to 600 by 2030,” Anil Dev, chief executive officer, CCT India, told THE WEEK.

The plant will manufacture central air-conditioning equipment such as screw chillers, magnetic levitation technology chillers, scroll chillers, conventional centrifugal chillers, high-precision AC units, and heat pumps for HVAC application. CCT has many customers in India, including global data centre companies, multinational hotel chains, health care establishments, malls, multiplexes, commercial projects of real estate developers, corporate groups and industrial applications.

“Reliable cooling systems are essential to prevent equipment failures in data centers. We are targeting the high demand from the data centers for our systems in India. This chiller market is concentrated largely in West India (Navi Mumbai), followed by Chennai, Bengaluru, Hyderabad, Pune and Kolkata. We had started the factory in 2020. Our facility will also manufacture different ranges of central air conditioning equipment for both domestic and international markets. We will always strive to bring efficient technologies to the Indian market and pursue ethical growth by giving the highest priority to sustainability and protection of the environment,” said Dev.

US businesses strike China deals in shadow of Trump victory

Published

on

Just as president-elect Donald Trump was being voted in on a platform of higher tariffs for China, US businessmen were striking deals thousands of miles away at Shanghai’s biggest trade fair.

Dynamite, a family-run pet food business with 12 stores in Idaho, signed $1mn in orders from Chinese company Pawberry — part of a stream of agricultural deals between the two countries this week that have so far amounted to $711mn.

“Every so often you meet someone in business you just click with — we understand each other,” said Joshua Zamzow, chief executive Dynamite, of his business partner at Pawberry. “He understands his market, and he’s taking the products that fit for the China market and just blowing them up . . . sales have begun to explode.”

But for businesses large and small, as election results flowed in from Georgia to Pennsylvania, it soon became clear that the wider relationship between America and China was entering a new era of uncertainty. Trump campaigned on a platform of higher tariffs — 60 per cent on Chinese goods — after a first term in which he launched a trade war that is still raging.

The US election this year coincided with the annual China International Import Expo, launched by Xi Jinping in 2018 and part of the government’s attempts to position itself as open to foreign business. This year it attracted thousands of companies — including more than half of the Fortune 500 — seeking to take advantage of China’s consumer market despite a tough economic backdrop.

Daniel Benefield, a representative of Rad Beverage International which was marketing products from Texas whiskey distillery Giant, said ahead of the result that he hoped his bourbon products would fly “under the radar” of any further escalation given their low market share.

“When you bring in a big percentage of a certain commodity, that’s your target. That’s why Australia got hit big time with the wine, that’s why Europe’s getting hit big time with the cognac.

“They sent soybeans back to the US, even though it was on the water,” he added, in reference to Chinese restrictions on the agricultural product that forms part of a series of retaliatory moves, most recently in response to European levies on Chinese electric vehicles. He added that his own imports — he gestures to a container of aged bourbon — were already subject to significant tariffs from China though he saw a “bright future” in the country.

Across the fair’s hundreds of stalls in a vast exhibition centre, there were relatively few Americans — a reflection of a wider decline that has seen foreign student numbers plummet, an exodus of US law firms from Shanghai and a general air of caution among US companies.

“US-China tensions [are] affecting the psyche of investment, there’s just no question about that,” said Allan Gabor, chair of the American Chamber of Commerce in Shanghai. “Some companies have taken some strategic decisions . . . but this is not generally the case,” he added, on the question of whether companies were leaving.

Longer-term planning in China now faces the prospect of further surprises. “The biggest concern for everybody is the unpredictability of Trump, and what comes out of Trump’s mouth and what actually gets executed,” said Kent D Kedl, former head of Control Risks in China and head of consultancy Blue Ocean Advisors. “The biggest risk to business is the unknown.

“The defining thing about China and the US is that it [China] is a domestic political issue in the US,” he added. “I have a number of friends who are now global CEOs because they came through [China], that is completely opposite now.”

Elsewhere in Shanghai’s exhibition centre, concerns over tariffs were not limited to US-China relations. “Probably they will [increase] tariffs . . . it will be harder for Brazilians to import to the US,” said Caio Livio Germano Alves, an exporter for beef company Bon-mart of a Trump presidency. By contrast, he expected to open more Brazilian beef sites in mainland China this month. “Our main market is China,” he said.

For Zamzow, Trump’s first victory in 2016 made business “harder” in China but “we found a way to still do business in a meaningful way”. “I think there was a lot of apprehension on behalf of Chinese people to invest in products and bring them in when they weren’t sure if he [Trump] was going to cut us off,” he said. “I think they realised and we realised it was OK.”

His relationship with his Pawberry partner, which came via a Taiwanese intern who was studying at Boise State University Idaho, also evolved. “He came to Idaho, and we went shooting guns, that was something he’d never seen before but it’s an Idaho cultural thing,” he said. “If you walk around this building, there are many business relations that started the same as ours, that today both parties are very, very wealthy, big corporations, but it started as friends”.

Throughout the building in Shanghai, even amid breaking news of the election, the focus was often far removed from politics. “For business people, we care about our basic living,” said one carpet salesman from Kashmir, who regarded China as “friendly” despite trade tensions between India and the mainland that echo strained relations with the US.

“In this room, it’s just business,” said Zamzow, who added that in his lifetime “almost no presidents ever do anything”. “We just want to make good products and buy good products and sell good products. The rest of it, it’s TV.”

Indonesia’s new president heads to China for first foreign trip in office

Prabowo Subianto is kicking off his first foreign tour as Indonesia’s president with a visit to top trading partner China, underscoring Beijing’s importance to south-east Asia’s largest economy.

Prabowo, who took office three weeks ago, will visit Beijing from Friday to Sunday and hold talks with China’s President Xi Jinping at the start of a five-country trip that will also include the US and UK.

Prabowo has yet to set out his diplomatic priorities or strategy, but has made clear he wants Indonesia to play a more active role in international affairs. China was also his first overseas stop after he won Indonesia’s presidential election in February.

Muhammad Zulfikar Rakhmat, director of the China-Indonesia Desk at the Center of Economic and Law Studies, said Prabowo was being pragmatic in prioritising Beijing.

“The visit indicates that China will be an important partner for Prabowo, especially for him to fulfil his economic promises,” he said.

Prabowo has vowed to boost annual economic growth to 8 per cent from about 5 per cent, a target economists have said will require increasing foreign direct investment.

China, Indonesia’s second-biggest source of FDI, was instrumental in helping Prabowo’s predecessor Joko Widodo to meet his economic goals by investing heavily in flagship projects and economically important sectors such as metals, mining, and infrastructure.

Chinese companies have pumped billions of dollars into Indonesia’s nickel industry as Jakarta sought to develop its reserves of the metal critical to steelmaking and electric vehicle batteries. Beijing also funded a $7.3bn high-speed rail line — Indonesia’s first — between Jakarta and Bandung as part of its $1tn global Belt and Road infrastructure initiative.

Prabowo has vowed to maintain Indonesia’s long-standing policy of international neutrality and analysts said he was seeking to balance his visit to China by immediately following it with a trip to the US, where he is expected to meet President Joe Biden and possibly president-elect Donald Trump.

Prabowo will then go to Peru for a meeting of the Asia-Pacific Economic Cooperation forum, to Brazil for a G20 summit and finally to the UK, where he will meet Prime Minister Keir Starmer.

“We must negotiate, explore existing potential, and resolve crucial and strategic issues with these countries, which are part of very important economic blocs. It is very crucial to the survival of our economy,” said Prabowo in a statement this week.

The president did not say whether one of those issues he planned to discuss would be China’s increased assertiveness in the South China Sea, where Beijing’s sweeping territorial claims appear to overlap with Indonesia’s exclusive economic zone.

Last month, the Indonesian coastguard said it had driven Chinese coastguard ships out of waters under Jakarta’s jurisdiction, where it said the vessels had been disrupting resource survey work.

Prabowo has previously called for a peaceful resolution of the South China Sea disputes.

Prabowo, who has said he wants to be “friends with all countries”, is keen for the world’s fourth most populous nation to play a more influential role in global affairs than it did under Widodo, who had a more domestic focus.

In the first three weeks of his presidency, Indonesia has announced that it will join the Brics grouping of major emerging economies that includes China and Russia and launched its first joint drills with the Russian military.

As defence minister in Widodo’s government, Prabowo last year proposed a demilitarised zone and a UN referendum to end the conflict between Ukraine and Russia, a plan rejected by Kyiv. This year, Prabowo said Indonesia was willing to send peacekeeping forces to Gaza.

“Indonesia under Prabowo will be more willing to work with everyone. Not just with Russia or China, but also the US, France and others,” said Evan Laksmana, senior fellow at the International Institute for Strategic Studies. 

“Prabowo himself will be Indonesia’s chief diplomat. What we will see is a more hands-on, active personal touch to foreign policy and international engagement.”
