The Northern Territory Government of Australia has provided an update to harbor users on the upcoming HMAS Coonawarra – Darwin Harbor dredging campaign.
According to the notification, Duratec Australia / HALL Contracting are to carry out dredging operations within the harbor of HMAS Coonawarra.
The aim of the project is to provide full-tide navigational access to the HMAS Coonawarra basin for new deeper-draft Australian naval vessels.
Dredged material removed by a cutter suction dredger (soft clay) will be discharged into Darwin Harbor at a location approximately 300m south-west of the dredging areas.
Rock material removed by the backhoe dredger will be barged to the East Arm Wharf ponds for land disposal.
Dredging operations will take place from 5 December 2023 to April 2024, during daytime hours only (6:30am to 6:00pm Monday to Saturday) with no dredging on Sundays or public holidays.
