For approximately 12 months, marine works involving dumping and trimming operations, hydrographic survey and water quality monitoring will be carried out in the area bounded by straight lines joining the following co-ordinates (WGS 84 Datum) from (A) to (J):
(A) 22 deg. 10.357’N / 114 deg. 01.090’E
(B) 22 deg. 10.151’N / 114 deg. 01.090’E
(C) 22 deg. 10.152’N / 114 deg. 02.323’E
(D) 22 deg. 09.291’N / 114 deg. 02.324’E
(E) 22 deg. 09.290’N / 114 deg. 01.836’E
(F) 22 deg. 09.144’N / 114 deg. 01.836’E
(G) 22 deg. 09.143’N / 114 deg. 01.091’E
(H) 22 deg. 08.948’N / 114 deg. 01.091’E

(J) 22 deg. 10.354’N / 113 deg. 58.001’E

The works will be carried out by a flotilla of vessels including hopper barges, grab dredgers and derrick lighters. Some tugboats and work boats 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 will be established around each working vessel. Yellow marker buoys fitted with yellow flashing lights will be laid to mark the positions of the anchors extending from the working vessels.

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

Silt curtains will be established at the dredging locations. A silt curtain is a large piece of netting used to contain mud and sediments.

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

Vessels navigating in the vicinity should proceed with caution, bearing in mind the changing depths in the works area.
