The wharf at Rio Tinto Aluminium’s Yarwun alumina refinery experienced vibrations during bauxite delivery. The wharf was scheduled for duplication and, due to these vibrations, concerns about the fatigue performance were expressed.

After consideration of access and occupational health and safety restrictions, Texcel collaborated with Bechtel Australia to understand the issues and develop a strategy to monitor the in-service performance of the wharf.

Bechtel utilised the monitoring results, in the form of the wharf’s dynamic response to operational events, to dismiss the fatigue concerns and open the way for the duplication.
