The works are being carried out by a flotilla of vessels including two dumb lighters, two hopper barges and two tugboats. The number of vessels engaged in the works changes from time to time to suit operational requirements.

A working area of approximately 50 metres around the lighters and barges is established. Yellow marker buoys fitted with yellow flashing lights are laid to mark the positions of the anchors extending from the lighters and barges.

Silt curtains fitted with yellow flashing lights are established within the works area. The silt curtain is a large piece of netting used to contain mud and sediments.

The works are being carried out from 0700 to 1900 hours. No works are carried out on Sundays and public holidays. Vessels employed for the works stay in the works area outside the hours of work.

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

Vessels navigating in the vicinity should proceed with caution.
