The works will be carried out by a flotilla of vessels including one dumb lighter, one flat-top work barge, three hopper barges and three tugboats. 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 the lighter and each 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 lighter and barges.
Silt curtains fitted with yellow flashing lights will be established within the works area. The silt curtain is a large piece of netting used to contain mud and sediments.
The works will be carried out from 0700 to 1900 hours. No works will be carried out on Sundays and public holidays. Vessels employed for the works will stay in the works area 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.
