Construction of the Cross Bay Link, marine works at Junk Bay

02 Sep 2022 / Hong Kong

For approximately 24 months, marine works involving construction of piers and viaducts 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. 17.732’N / 114 deg. 15.462’E
(B) 22 deg. 17.646’N / 114 deg. 15.655’E
(C) 22 deg. 17.578’N / 114 deg. 15.622’E
(D) 22 deg. 17.657’N / 114 deg. 15.425’E

WORKS AREA 2
This area is bounded by straight lines joining the following co-ordinates (WGS 84 Datum) from (E) to (K) and the adjacent shoreline:
(E) 22 deg. 17.513’N / 114 deg. 16.017’E
(F) 22 deg. 17.488’N / 114 deg. 16.017’E
(G) 22 deg. 17.487’N / 114 deg. 15.847’E
(H) 22 deg. 17.556’N / 114 deg. 15.675’E
(I) 22 deg. 17.624’N / 114 deg. 15.708’E
(J) 22 deg. 17.571’N / 114 deg. 15.863’E
(K) 22 deg. 17.561’N / 114 deg. 16.003’E

The works will be carried out by a flotilla of vessels including dumb lighters and special purpose vessel. 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 around each lighter will be established. Yellow marker buoys fitted with yellow flashing lights will be laid to mark the positions of the anchors extending from the lighters.

A temporary navigation channel with a width of about 100 meters will be provided between the two Works Areas. The channel will be marked by lateral light buoys. The particulars of the buoys are as follows:

  • Red lateral light buoys at co-ordinates (B) and (C):
    Shape: Pillar
    Colour: Red
    Top Mark: Can
    Light Characteristics: Q.R
    Radar Reflector: Fitted
  • Green lateral light buoys at co-ordinates (H) and (I):
    Shape: Pillar
    Colour: Green
    Top Mark: Cone
    Light Characteristics: Q.G
    Radar Reflector: Fitted

Silt curtains extending from the sea surface to the seabed will be established within the works areas. 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 from 0700 to 2200 hours daily. Vessels employed for the works will stay in the works areas 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.
