Marine works south-east of Hong Kong International Airport
For approximately 12 months, marine works involving seawall construction and removal of temporary toe loading platform will be carried out in the area bounded by straight lines joining the following co-ordinates (WGS 84 Datum) from (A) to (E) and the adjacent shoreline:
(A) 22 deg. 18.669’N / 113 deg. 56.467’E
(B) 22 deg. 18.639’N / 113 deg. 56.663’E
(C) 22 deg. 18.134’N / 113 deg. 56.599’E
(D) 22 deg. 17.777’N / 113 deg. 56.409’E
(E) 22 deg. 17.687’N / 113 deg. 56.303’E
Yellow marker buoys fitted with yellow flashing lights will be laid to mark the boundary of the works area at co-ordinates from (B) to (D).
The works will be carried out by a flotilla of vessels including derrick lighters, flat top barges, hopper barges and pelican barges. Some tugboats and work 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 50 metres will be established around each of the derrick lighters and barges. Yellow marker buoys fitted with yellow flashing lights will be laid to mark the positions of the anchors extending from the working vessels.
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. Vessels employed for the works will stay in the works area outside 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.
