Deployment of artificial reefs west of International Airport

11 Oct 2024 / Hong Kong

For approximately 15 months, artificial reefs will be established on the seabed within the area bounded by straight lines joining the following co-ordinates (WGS 84 Datum) from (A) to (D):
(A) 22° 18.598’N / 113° 53.168’E
(B) 22° 18.340’N / 113° 53.258’E
(C) 22° 18.256’N / 113° 52.982’E
(D) 22° 18.514’N / 113° 52.891’E

The artificial reef is cylindrical in shape with a height of about 1.2 metre and a base of about 1.3 metre in diameter. There will be a vertical clearance of about 4.5 metres from the top of the artificial reef to sea level.

The works will be carried out by one dumb lighter and one tugboat. Another dumb lighter, one crane barge and one work boat will provide assistance.

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

A working area of approximately 50 metres around the working vessels will be established. 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 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 works.

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