Maintenance dredging at Castle Peak Power Station Jetty, Tap Shek Kok

11 Feb 2021 / Hong Kong

For approximately one month, dredging operations will be carried out within the area bounded by straight lines joining the following co-ordinates (WGS84 Datum) from (A) to (D) and the adjacent shoreline:
(A) 22° 22.274’N / 113° 55.170’E
(B) 22° 22.196’N / 113° 55.089’E
(C) 22° 22.403’N / 113° 54.858’E
(D) 22° 22.480’N / 113° 54.938’E

The works will be carried out by one grab dredger. Two split hopper barges and one tugboat will 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 metres around the grab dredger will be established. Yellow marker buoys fitted with yellow flashing lights will be laid to mark the positions of the anchors extending from the dredger.

The hours of work will be round-the-clock.

A silt curtain, extending from the sea surface to the seabed, will be established beside the grab dredger. The silt curtain is a large piece of netting used to contain mud and sediments. Yellow flashing lights will be laid to mark the extent of the silt curtain.

Vessels engaged in the operations will display signals as prescribed in international and local regulations.

Vessels navigating in the vicinity should proceed with caution.
