Australia’s first wind fences mitigate dust for BHP

BHP is partnering with CIMIC Group’s CPB Contractors to build Australia’s first wind fences, which will mitigate dust emissions at the miner’s Port Hedland operations.

Designed for the Pilbara’s unique weather conditions, and rated specifically to withstand cyclones, the three fences will include mesh panels to reduce wind speeds, shielding BHP’s stockpiles and reducing the potential for dust lift-off.

30m high and spanning a length of two kilometres, the fences will abate dust emissions in current operations and ensure no net increases in dust emissions should operations expand over time.

Up to 150 employees are expected to be involved in the construction of the project, with up to 10 per cent Indigenous employment in those numbers.

BHP Port general manager Cindy Dunham said the wind fences would be constructed using global best practice dust management and air quality control technology.

“The investment forms part of our Pilbara Air Quality Program and demonstrates our commitment to the region and contribution to the revitalisation of the West End.

“The wind fence project is a key part of our commitment towards continued improvement of our existing dust control measures as we look to continue growing production over time.”

CPB Contractors general manager WA, SA & NT, Andrew Giammo, said the innovative environmental project would provide lasting benefits for the community of Port Hedland.

“Construction of the wind fences will involve the fabrication of 3000 tonnes of structural steel – this work will be undertaken here in WA and will be a major boost to local industry,” he said.

“Throughout the life of the project, we’ll also be looking to maximise opportunities for Indigenous businesses and employment.”

BHP is spending up to $300 million over the next four years as part of its Pilbara Air Quality Program, which also includes continued implementation and optimisation of operational dust control projects across its Pilbara supply chain, to improve existing controls at mines and ports.
