Stage 2, Washer Bridge Support Upgrade

Project Details

10km northwest of Gladstone, QLD sits Yarwun Alumina Refinery. Producing Alumina & hydrate, Yarwun refinery sees almost 3 million tonnes of alumina produced per year. To support this undertaking, Pructon was engaged to strengthen tank structures by replacing supporting members. These supporting members provide a foundation to support the centre tank top which in turn is supported off the walkways bridge above. The installation of these members has increased the safety longevity of the tank.

The tank requiring support is a significant part of the extraction process for aluminum, holding the bauxite sludge. As such a shutdown period was required with 24-hour shifts to ensure operations could resume quickly.
