Hydrographic surveys will happen within the Ashburton Cargo Wharf channel, swing basin, berth pockets, and the Mineral Assets berth pocket, with subsequent sweeping to be carried out in these areas if required.
The dredging and help vessels concerned within the marketing campaign embody the trailing suction hopper dredger Nile River, the sweep vessel Vantage, and the survey vessel Puriya. The dredged materials can be transported to designated spoil and holding grounds.
Mariners have been suggested that the vessels concerned within the operation can be restricted of their capacity to manoeuvre and have to be navigated round with warning.
