HMAS Brisbane Karumba

Maintenance Dredging Dredging of the entrance channel started in early June 2004 and continued for just under five weeks. A total of 221,000m3 of material was dredged and relocated to an approved offshore material relocation ground. The dredging is required to remove siltation from the channel to ensure that channel depths are maintained in the Norman River and approaches for Zinifex’s transfer vessel Wunma. The Port of Brisbane Corporation completed the dredging with their dredger, Brisbane. The project was undertaken in conjunction with Zinifex Century Mine and was completed under budget at a cost of $1.75 million. http://www.pcq.com.au/downloads/2005_PCQ%20Ports%20Report.pdf
