For approximately three months, marine site investigation works involving drilling of boreholes will be carried out in the following locations (WGS 84 Datum):
(A) 22º 31.787’N / 114º 15.802’E

The works will be carried out by one jack-up barge. One tugboat and one work boat will provide assistance.

A working area of approximately 20 metres around the barge will be established. Yellow flashing lights will be installed at the four corners of the barge to indicate its position.

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 locations outside the hours of work.

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.

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 area.
