Yellow marker buoys fitted with yellow flashing lights will be laid at co-ordinates (B), (D), (F), (G), (I), (J) and (K) to mark the boundary of the works area.

The works will be carried out by a flotilla of vessels including dumb lighters, special purpose vessels, flat-top barges, crane barges, jack-up barges and cement barges at various stages. Tugboats, landing pontoons and work boats will provide assistance. 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 will be established around each working vessel. Yellow marker buoys fitted with yellow flashing lights will be laid to mark the positions of the anchors extending from the working vessels.

Yellow flashing lights will be installed at the four corners of the jack[1]up barges to indicate the positions of the jack-up barges.

Silt curtains, extending from the sea surface to the seabed, will be established around the boundary of the works area. The silt curtain is a large piece of netting used to contain mud and sediments. Yellow marker buoys fitted with yellow flashing lights will be laid to mark the extent of the silt curtains.

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.

Diving operations will be carried out from time to time during 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 and keep clear of the works area at slow speed, bearing in mind there are divers working in the area.
