Yellow marker buoys fitted with yellow flashing lights and radar reflectors will be laid at co-ordinates (F), (I), (J), (K), (L), (M) and (Q) to mark the boundary of the works area.
Cardinal mark buoys will be laid at co-ordinates (D), (E), (O) and (P) to indicate the safe side on which to pass the works area. The characteristics of the cardinal mark buoys are as follows:
Co-ordinate (D) : 22º18.558’ N 113º52.096’ E
Shape : Pillar
Colour : Black horizontal band on a yellow body
Light : 9 flashes
Top Mark : Cones point towards each other
Radar Reflector : Fitted
Co-ordinate (E) : 22º18.835’ N 113º52.139’ E
Shape : Pillar
Colour : Black horizontal band on a yellow body
Light : 9 flashes
Top Mark : Cones point towards each other
Radar Reflector : Fitted
Co-ordinate (O) : 22º20.214’ N 113º55.994’ E
Shape : Pillar
Colour : Yellow horizontal band on a black body
Light : 3 flashes
Top Mark : Cones point away from each other
Radar Reflector : Fitted
Co-ordinate (P) : 22º20.097’ N 113º56.257’ E

The works will be carried out by a flotilla of vessels including special purpose vessels, pelican barges, cement supply barges, derrick lighters, roro barges and flat top barges. Tugboats, work boats and guard 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 150 metres will be established around each special purpose vessel. Yellow marker buoys fitted with yellow flashing lights will be laid to mark the positions of the anchors extending from the special purpose vessels.
A working area of approximately 50 metres will be established around each derrick lighter and barge. Yellow marker buoys fitted with yellow flashing lights will be laid to mark the positions of the anchors extending from the derrick lighters and barges.
The water depth at the works area will be reduced.
To safeguard the marine works operations and ensure navigational safety, guard boats will station in the works area and patrol the waters in the vicinity to give necessary guidance to the vessels approaching the works area.
Silt curtains, extending from the sea surface to the seabed, will be established around the boundary of 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 curtains.
The hours of work will be round-the-clock including Sundays and public holidays. 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.
