The works will be carried out by one grab dredger, four hopper barges, one derrick lighter, three tugs, and one survey boat. The number of vessels engaged in the works will change from time to time to suit operational requirements.
A working area of approximately 50 m around the dredger has been established. Yellow marker buoys fitted with yellow flashing lights were laid to mark the positions of the anchors extending from the dredger.
Silt curtains, extending from the sea surface to the seabed, have been established within the works area. The silt curtain is a large piece of netting used to contain mud and sediments.
The hours of work will be from 07:00 h to 19:00 h local time. No works will be carried out on Sundays and public holidays. Vessels engaged in the works will stay in the works area outside the hours of work.
