Dredging operations have started in Causeway Bay Typhoon Shelter in Hong Kong, according to a notice of Hong Kong Marine Department.
The operations will be completed in approximately two months.
The works will be carried out by one derrick barge while three tugs will provide assistance.
A working area of approximately 20 m around the 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 barge.
A silt curtain, extending from the sea surface to the seabed, will be established within the working area. The silt curtain is a large piece of netting used to contain mud and sediments.
The hours of work will be from 07:00 h to 23:00 h local time. Vessels engaged in the works will stay in the working area outside the hours of work.
