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.

A working area of approximately 50 metres around each working craft 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 crafts.

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