A single derrick lighter will carry out the work, with a tug and work boat providing assistance.
The lighter will work at a single beacon at a time, and will alternate amongst the four beacons to suit operational requirements.
A working area of approximately 30 metres around the lighter will be established.
Yellow marker buoys fitted with flashing lights will be laid to mark the positions of the anchors extending from the lighter.
Hours of work will be from 0700 to 1900 hours. No works will be carried out on Sundays and public holidays.
Outside the hours of work, the vessels employed for the works will remain close to the beacon undergoing reconstruction works.
Vessels engaged in the operations will display signals as prescribed withiin international and local regulations.
Vessels navigating in the vicinity should proceed with caution and keep clear at slow speed, bearing in mind there are divers working in the area.
