(K) 22 deg. 16.083’N / 114 deg. 15.010’E

The works will be carried out by a flotilla of vessels including one cable-laying barge, one derrick barge, one flat top barge, one tugboat and two guard boats. The number of vessels engaged in the works will change from time to time to suit operational requirements.

A working area of approximately 100 metres around the cable-laying barge and the derrick 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 cable-laying barge and the derrick barge.

A working area of approximately 50 metres around the flat top 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 flat top barge.

The hours of work will be from 0700 to 2300 hours. Vessels employed for the works will stay in the works area outside the hours of work except the period when working inside the Tathong Channel Traffic Separation Scheme.

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

Diving operations will be carried out from time to time.

Vessels navigating in the vicinity should proceed with caution at a slow speed and keep clear of the barges, bearing in mind that there are divers working in the area.
