1. The works will be carried out by one special purpose vessel, one flat-top work barge and one dumb lighter. Two tugboats and one transportation boat will provide assistance. The number of vessels engaged in the works will change from time to time to suit operational requirements. Vessels engaged in the works will display signals as prescribed in international and local regulations.

2. The hours of work will be round-the-clock. A working area of approximately 100 metres around the working vessels will be established. Yellow marker buoys fitted with yellow flashing lights will be laid to mark the positions of the anchors extending from the working vessels.

3. A silt curtain, extending from the sea surface to the seabed, will be established beside the flat-top work barge. The silt curtain is a large piece of netting used to contain mud and sediments. Yellow flashing lights will be laid to mark the extent of the silt curtain.

4. Diving operations will be carried out from time to time during the hours of work. Vessels navigating in the vicinity should proceed with caution and keep clear of the works area at slow speed, bearing in mind that there are diving operations in the area.
