FINDING a better way is in Ausenco’s DNA.
Ausenco responded to the challenge at Carrapateena with an optimised design honed by experience delivering successful copper concentrators globally.
Compared to the pre-feasibility design, Ausenco’s design resulted in 30pc less power usage, 50pc footprint reduction and improved operability and maintainability – delivering reduced environmental impact and improved sustainability.
An efficient design
A lean, compact processing plant lowers capital cost and drives efficiency in delivery without compromising operability or maintainability.
Ausenco delivered a plant that reduces the number of people required in operations, with consideration to ready access, data gathering and analytics and general operations.
The result was reduced bulk commodities, and less energy to operate, enhancing both safety and sustainability outcomes.
A smarter process
Ausenco embedded technology into the
Carrapateena design that created a
‘thinking’ plant.
Using sophisticated instruments and analysis, Ausenco’s Advanced Process Control optimises energy use and allows the process team to concentrate on high value activities.
A safer way
Using Ausenco’s Safety in Design Protocols, the company minimised the need for interactions between people, mine equipment and vehicles.
Working with joint venture partner Downer, Ausenco considered constructability elements such as lifts; limited working at heights; simplified construction; and traffic management and access control.
A win for community
From the outset, the company created shared value and sustainable benefits for the local, and broader, South Australian community.
Goods and services were procured out of South Australia as a priority.
Local South Australians comprised 30pc of the workforce.
Ausenco’s Regional Economic Solutions business unit worked with the Kokotha people, to deliver employment programs that resulted in 11pc of the construction labour force being sourced from the local Port Augusta community.
On-the-job training, mentoring and upskilling programs such as rotational opportunities helped broaden experience and capabilities, and created sustained employment opportunities for local community members.
