22 Oct 2020 / Hong Kong

For approximately 3 months, trial deployment of one artificial reef will be temporarily established on the seabed in the following location (WGS 84 Datum): 22° 19.881’N / 113° 59.014’E.

The artificial reef is cubical in shape with a height of about 6.3 metres and a base of about 4.2 metres by 4.2 metres. There will be a vertical clearance of about 4.5 metres from top of the artificial reef to sea level. A yellow marker buoy fitted with yellow flashing light will be laid to mark the position of the artificial reef.

The works for the trial deployment will be carried out by one crane barge and one flat top barge. Two tugboats will provide assistance.

A working area of approximately 50 metres around each barge will be established. Yellow markers buoys fitted with yellow flashing lights will be laid to mark the positions of the anchors extending from each barge.

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

Diving operations for checking the artificial reef 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 location.
