The works will be carried out by two flat top barges and one jack-up barge. One work boat and two tugboats will provide assistance.

A working area of approximately 50 metres will be established around each barge. Yellow marker buoys fitted with yellow flashing lights will be laid to mark the positions of the anchors extending from the flat top barges.

Yellow flashing lights will be installed at the four corners of the jack-up barge to indicate its position.

The hours of work will be from 0800 to 1800 hours. No works will be carried out on Sundays and public holidays. Vessels employed for the works will stay in the works area outside the hours of work.

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

Vessels navigating in the vicinity should proceed with caution.
