(B) 22° 15.926’N 114° 16.895’E
(C) 22° 15.906’N 114° 16.810’E
(D) 22° 15.984’N 114° 16.789’E

This area is bounded by straight lines joining the following co-ordinates (WGS 84 Datum) from (E) to (H):
(E) 22° 15.795’N 114° 16.737’E
(F) 22° 15.637’N 114° 16.778’E

The works will be carried out by a flotilla of vessels including two dumb lighters, one hopper barge, one crane barge, one flat-top work barge, one special purpose vessel, one tug and one work boat. The number of vessels engaged in the works will change from time to time to suit operational requirements.

A working area of approximately 80 metres will be established around each lighter. Yellow marker buoys fitted with yellow flashing lights will be laid to mark the positions of the anchors extending from the lighters.

Silt curtains extending from the sea surface to the seabed will be established within each works area. The silt curtain is a large piece of netting used to contain mud and sediments.

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 areas outside the hours of work.

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

Vessels engaged in the works 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 areas at slow speed, bearing in mind there are divers working in the works areas.
