The Northern Territory Government of Australia has presented update to the port users regarding the upcoming HMAS Coonawarra Dredging Campaign – Darwin Harbour.
According to the notification, Duratec Australia / HALL Contracting are to conduct dredging operations within HMAS Coonawarra harbour.
The aim of the project is to provide all-tide navigation access at the HMAS Coonawarra basin for new, deeper draft Australian naval vessels.
Dredged material removed by a cutter suction dredge (soft clay) will be discharged to Darwin Harbour at a location approximately 300m southwest of the dredge areas.
The rock material removed by backhoe dredge will be transported on barges to the East Arm Wharf ponds for land-based disposal.
Dredging operations will take place from 5 December 2023 till April 2024, during daylight hours only (0630 am-1800 pm Monday to Saturday) with no dredging on Sundays or public holidays.
