Dredging work is now under way at the entrance to Eyemouth Harbour.
The job is expected to take hopper barge MV Sandsend and dredging pontoon Saltwick weeks to complete.
Eyemouth Harbour Trust has advised mariners that the work, commenced on Friday, April 22, was expected to continue into May.
Any vessels entering or leaving the harbour while dredging operations are going on need to contact either the harbour master, Richard Lawton, or MV Sandsend, using VHF channel 12 if possible.
A berth in Gunsgreen Basin has been reserved for the dredging vessels, and other boats may be asked to move berth as directed by the harbourmaster to enable the dredging operation to proceed.
Eyemouth harbour is part of the Berwickshire and North Northumberland coast European marine site, so all removal of deposits from the seabed requires a marine licence from either the Marine Management Organisation or Marine Scotland.
Dredging takes place regularly at Eyemouth Harbour, the last such operation being in 2014, to remove sand, silt and other materials that come in from the sea, plus additional sediment from the Eye Water.
