Laying of water pipeline

For approximately 12 months, marine works involving barging operations and water pipeline installation will be carried out [between Tai Kwai Wan, Cheung Chau and Ha So Pai, Lantau Island] in the following areas:

AREA 1:
This area is bounded by straight lines joining the following co-ordinates (WGS 84 Datum) from (A) to (D) and the adjacent shoreline:
(A) 22 deg. 12.877’N / 114 deg. 01.508’E
(B) 22 deg. 12.967’N / 114 deg. 01.427’E
(C) 22 deg. 13.049’N / 114 deg. 01.501’E
(D) 22 deg. 12.973’N / 114 deg. 01.569’E

AREA 2:
This area is bounded by straight lines joining the following co-ordinates (WGS 84 Datum) from (E) to (H) and the adjacent shoreline:
(E) 22 deg. 13.562’N / 114 deg. 01.052’E
(F) 22 deg. 13.537’N / 114 deg. 01.082’E
(G) 22 deg. 13.499’N / 114 deg. 01.037’E
(H) 22 deg. 13.532’N / 114 deg. 01.013’E

The works will be carried out by two derrick lighters. Some tugs and one work boat 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 working vessel. Yellow marker buoys fitted with yellow flashing lights and radar reflectors will be laid to mark the positions of the anchors extending from the working vessels.

The hours of work will be from 0700 hours 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.

A silt curtain, 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. Yellow markers fitted with yellow flashing lights will be laid to mark the extent of the silt curtain.

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

Vessels navigating in the vicinity should proceed with caution.
