Dredging operations has commenced at Hong Kong’s Hung Hom Fairway, and will be carried out for a period of approximately one month until mid-May, a notice from the Hong Kong Marine Department said.
The dredging works are within the area bounded by straight lines joining the following co-ordinates (WGS 84 Datum) from (A) to (D): (A) 22º17.553′ N 114º11.024′ E, (B) 22º17.489′ N 114º11.039′ E, (C) 22º17.475′ N 114º10.962′ E, and (D) 22º17.539′ N 114º10.947′ E.
The works are being carried out by one grab dredger and one hopper barge. One tug and one workboat provide assistance.
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 and barge were established. Yellow marker buoys fitted with yellow flashing lights were laid to mark the positions of the anchors extending from the dredger and barge.
A silt curtain, extending from the sea surface to the seabed, were established within the working area. The silt curtain is a large piece of netting used to contain mud and sediments. Yellow markers fitted with yellow flashing lights were laid to mark the extent of the silt curtain.
The working hours are from 07:00 h to 23:00 h. Vessels employed for the dredging will stay in the working areas outside the working hours.
