For approximately 3 months, replacement of water pipeline [between Peng Chau and Sunshine Island] will be carried out within the following works areas:

WORKS AREA 1
This area is bounded by straight lines joining the following co-ordinates (WGS 84 Datum) from (A) to (D):
(A) 22 deg. 16.292’N / 114 deg. 02.901’E
(B) 22 deg. 16.244’N / 114 deg. 02.919’E
(C) 22 deg. 16.233’N / 114 deg. 02.862’E
(D) 22 deg. 16.283’N / 114 deg. 02.852’E

WORKS AREA 2
This area is bounded by straight lines joining the following co-ordinates (WGS 84 Datum) from (E) to (H):
(E) 22 deg. 15.954’N / 114 deg. 03.042’E
(F) 22 deg. 15.854’N / 114 deg. 03.048’E
(G) 22 deg. 15.854’N / 114 deg. 03.040’E
(H) 22 deg. 15.952’N / 114 deg. 03.037’E

The works will be carried out by two work boats. A working area of approximately 25 metres will be established around the work boats. Yellow marker buoys fitted with yellow flashing lights will be laid to mark the positions of the anchors extending from the work boats.

3. A temporary water pipeline will be laid in Works Area 2. To secure the temporary water pipeline, some concrete blocks will be laid on the seabed within the Works Area 2. Each concrete block is a structure of cube shape with a height of 0.2 metres and a square base of 0.3 metres by 0.3 metres. Upon completion of the replacement works, the temporary water pipeline and concrete blocks will be removed from the Works Area 2.

The hours of work will be from 0700 to 1900 hours. No works will be carried on Sundays and public holidays. Vessels employed for the works will not stay in the works area outside the hours of work.

Diving operations 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 areas at slow speed, bearing in mind there are divers working in the areas.
