Principal: Gladstone Ports Corporation
Location: Bundaberg, Qld
Contract Value: $2,940,000
Completion Date: December 2013
In January 2013, the Port of Bundaberg was significantly impacted by flooding, which caused unprecedented siltation in the port channel, swing basin and berth pockets. Apart from the unprecedented siltation event in the channel, the port also experienced major scouring and deepening of the river bed along significant sections of the toe of the northern training rock wall. This has led to the development of deep trenches along the toe of the wall which has threatened the stability of the wall.
As part of an overall dredging strategy to return the Port of Bundaberg to normal operating depths, dredging of approximately 400,000 m3 from the Swing Basin, Berths, Departure and Inner Reach of the Channel was conducted using a 450mm cutter suction dredge. The dredged material was pumped via 1500m of floating pipeline to a spreader barge which placed the material in designated areas along the toe of the Port’s northern rock training wall. This project provided the Port with the dual benefits of improving port clearance depths for shipping, and stabilising the base of the northern training wall.
The project was completed on a 24 hour, 7 day per week basis.
