For approximately 4 months, repair works for a light beacon will be carried out within the area bounded by straight lines joining the following co-ordinates (WGS 84 Datum) from (A) to (D):
(A) 22 deg. 25.776’N / 113 deg. 55.288’E
(B) 22 deg. 25.776’N / 113 deg. 55.346’E
(C) 22 deg. 25.722’N / 113 deg. 55.346’E
(D) 22 deg. 25.722’N / 113 deg. 55.288’E

The works will be carried out by a derrick barge. One crane boat and one tugboat will provide assistance.

A working area of approximately 15 metres around the derrick barge will be established. Yellow marker buoys fitted with yellow flashing lights will be laid to mark the positions of the anchors extending from the barge.

A silt curtain, extending from the sea surface to the seabed, will be established within the works area. The silt curtain is a large piece of netting used to contain mud and sediments. Yellow marker buoys fitted with yellow flashing lights will be laid to mark the extent of the silt curtain.

The hours of work will be from 0700 to 1900 hours. No works will be carried out on Sundays and public holidays. Vessels employed for the works will stay in the works area outside the hours of work.

Diving operations will be carried out from time to time during the hours of work.

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

Vessels navigating in the vicinity should proceed with caution and keep clear of the works area at slow speed, bearing in mind there are divers working in the works area.
