With immediate effect and for approximately 3 months, rock excavation and dredging works will be carried out within the area bounded by straight lines joining the following co-ordinates (WGS 84 Datum) from (A) to (D):
(A) 22 deg. 20.893’ N / 114 deg. 07.175’ E
(B) 22 deg. 20.784’ N / 114 deg. 07.212’ E
(C) 22 deg. 20.733’ N / 114 deg. 07.038’ E
(D) 22 deg. 20.842’ N / 114 deg. 07.001’ E
The works will be carried out round-the-clock by one drilling barge. One grab dredger, two split hopper barges and two tugboats will assist in the works. The number of vessels engaged in the works will change from time to time to suit operational requirements.
A working area of approximately 150 metres around the drilling barge will be established. Yellow marker buoys fitted with yellow flashing lights will be laid to mark the positions of the anchors extending from the drilling barge.
Vessels engaged in the operations will display signals as prescribed in international and local regulations. Vessels navigating in the vicinity should proceed with caution.

The soil investigation works will entail borehole drilling, seabed surface sampling, and marine cone penetration test. Jack-up barges and crane barges will be used to carry out the soil investigation work. Tug boats will be used to shift jack-up barges and crane barges. The circular safety zone for the borehole drilling and marine cone penetration test are 50m and 150m respectively.
Self-Discharge Sand Carriers (SDSC) and Trailer Suction Hopper Dredger (TSHD) will discharge sand at the designated temporary area.
Dredging operations consist of Trailer Suction Hopper Dredger (TSHD), Cutter Suction Dredger (CSD) and grab dredger/ backhoe dredger mobilization to the working area, dredging of clayey/ sandy/ residual soils.
The reclamation works consist of transport and discharge of materials utilizing TSHD, CSD, flat top barges, hopper barges, and conveyor barges.
Safety boats will be deployed to warn other craft in the vicinity of the working area.
When in the vicinity of the working area, mariners are reminded to:
a) Keep well clear and not to enter the working area;
b) Maintain a proper lookout;
c) Proceed at a safe speed and navigate with caution;
d) Maintain a listening watch on VHF Channel 22 (Jurong Control);
