Vessels navigating in the vicinity should proceed with caution. Vessels engaged in the operations will display signals as prescribed in international and local regulations.
The work involves marine ground investigation, laying of geotextiles and sand blankets. Deep cement mixing will also be carried out within the area bounded by straight lines joining the following co-ordinates (WGS 84 Datum) from (A) to (I) and the adjacent shoreline.
Yellow marker buoys fitted with yellow flashing lights will be laid at co-ordinates from (B) to (H) to mark the boundary of the works area.
The works will be carried out by a flotilla of vessels including flat top barges, jack-up barges, derrick lighters, and deep cement mixing barges at various stages. Some tugboats, guard boats and self-propelled delivery barges will provide assistance.
The number and type of vessels engaged in the works will change from time to time to suit operational requirements.
A working area of 50 metres around each barge and lighter will be established. Yellow marker buoys fitted with yellow flashing lights will be laid to mark the positions of the anchors extending from the barges and lighters.
Silt curtains, extending from the sea surface to the seabed, will be established within the works area. The silt curtain is a large piece of netting used to contain mud and sediments. Yellow markers fitted with yellow flashing lights will be laid to mark the extent of the silt curtains.
The water depth at the areas where sand blankets are laid will be reduced by two metres. Yellow marker buoys fitted with yellow fixed lights will be laid to mark the boundaries of such areas.
The hours of work will be from 0700 to 2300 hours including Sundays and public holidays. Vessels employed for the works will stay in the works area outside the hours of work.
