transhippers Archives - International Mining

Mineral Resources says its Onslow Iron project has reached a major milestone with the successful launch of Western Australia’s first shallow draft and fully enclosed transhipper.

Transhippers, designed by MinRes in collaboration with naval architects, as well as local and international engineering firms, are key to this large iron ore project. The vessels significantly reduce the project’s cost and environmental footprint as their shallow draft means millions of tonnes of iron ore can be shipped without the need for a deep-water port, according to MinRes.

Transhippers are also an integral part of MinRes’ dust-free mine-to-ship transport solution as they will be fully enclosed to ensure no dust pollution in Onslow from MinRes operations, it added.

Each transhipper is named after an island off the Pilbara coast, with the first, MinRes Airlie, launched into the water in March, one year after construction started at the COSCO shipyard in Zhoushan, China.

Onslow Iron will see ore transported by fully covered road trains along a dedicated haul road from the Ken’s Bore mine, 150 km east of Onslow, to the Port of Ashburton. At the port, the ore is transferred to a 220,000 t enclosed negative pressure storage facility. From there, it will be moved via covered conveyors into the transhipper’s “hopper” storage area.

At 123-m long and 36-m wide, the transhippers will have a 7-m draft when fully loaded, transporting ore to capesize bulk carriers anchored 40 km off the Pilbara coast.

This design drastically reduced the amount of seabed dredging required for the loading berth at the Port of Ashburton, according to MinRes

“When operating off the Pilbara coast, the five transhippers will be propelled by powerful tugs that provide crew with home-like comforts and high spec finishes,” the company said.

Transhippers are equipped with a loading system that distributes the ore throughout the vessel’s hold. Once ready for discharge, the ore drops onto conveyors that feed a loading boom into capesize bulk carriers.

MinRes Managing Director, Chris Ellison, said: “The successful launch of our first transhipper, MinRes Airlie, is a significant milestone in the development of our Onslow Iron project, which is set to redefine mining in Western Australia. Transhippers are just the latest example of the cutting-edge innovation being designed and developed by MinRes and are crucial to how we will unlock stranded iron ore deposits in the West Pilbara.

“The unique design of these shallow draft vessels means we don’t need to build deep-water berths, drastically reducing both the cost and environmental footprint of this landmark project. The interior fit-out of these vessels demonstrates our commitment to setting a new standard for workplace wellness, whether our people work in our state-of-the-art headquarters in Perth or at sea on a transhipper.”

MinRes’ A$3 billion ($2 billion) Onslow Iron project is, MinRes says, set to redefine mining in Western Australia, shipping around 35 Mt/y of iron ore from mid-2024.

Fitting out of MinRes Airlie will continue throughout 2023 ahead of an expected arrival in Western Australia early next year.

Onslow Iron is owned through the unincorporated Red Hill Iron Joint Venture, which is 40% held by MinRes, who will manage the project, with the other partners being Baowu, AMCI and POSCO.

Mineral Resources has commenced early works at its Onslow Iron project in the Pilbara region of Western Australia, a project that, according to Chris Ellison, will be “dust-free from pit-to-port”.

The early works at Onslow, formerly known as the Ashburton project, will support first ore on ship around December 2023, MinRes says.

Onslow Iron will unlock stranded deposits that would otherwise remain undeveloped in the West Pilbara region, using MinRes’ innovative and proprietary equipment designed to process and move bulk commodities at lower costs and with a reduced environmental footprint, the company said.

Following receipt of preliminary approvals, project preparations are on track and early construction activities including bulk earthworks have commenced at the Port of Ashburton, south of Onslow. At the nearby Truck Maintenance Facility, installation of the temporary construction village is underway, with first buildings to be installed from early September.

Mine development activities have also progressed at the Ken’s Bore Deposit, east of Onslow, with construction of the A320-capacity airport and the installation of two camps to support drilling and early construction works.

Recruitment for the construction phase of Onslow Iron is also well underway alongside a continued focus on community and stakeholder consultation.

In line with the project schedule, long-lead items have been ordered including the first transhippers, which will be used to load capesize vessels that will be anchored offshore from the Port of Ashburton. Each transhipper has a 20,000-t capacity, is fully enclosed to avoid dust pollution and has a significantly lower environmental footprint when compared with the major dredging activities that would be required to construct deepwater berths at the port, according to the company.

Onslow Iron will be one of the largest iron ore developments undertaken in Western Australia, delivering substantial benefits to the state including thousands of construction and operational jobs, billions of dollars of direct local investment through capital expenditure and billions of dollars of state and commonwealth royalties over the life of the project, it added.

Mineral Resources Managing Director, Chris Ellison, said: “Onslow Iron will be transformational, not just for MinRes but for the State of Western Australia. This project will be the cornerstone of our iron ore strategy to deliver low-cost, long-life operations with project economics that are compelling through commodity price cycles.

“We’re looking forward to delivering thousands of jobs for Western Australians and investing billions in the economy.

“Importantly, our innovations will drive lower emissions across the project. Onslow Iron has been designed with a low environmental footprint and will be dust-free from pit-to-port.

“We’re also setting a new FIFO standard with our industry first, resort-style accommodation to ensure the physical and mental safety of our people and to encourage more women, and couples, to live on site.

“It’s in our DNA to aim higher, push the boundaries and forge new paths, which is why Onslow Iron really represents a new paradigm for mining in Western Australia.”

On top of the dust-free innovation and FIFO aims, MinRes has mooted it will run autonomous road trains between the pit and the port at Onslow Iron.
