Water pipeline laying between Tai Kwai Wan, Cheung Chau & Ha So Pai, Lantau Island

For approximately 3 months, marine works involving drilling of a pilot hole, laying of submarine concrete blocks and tracking cables including diving operations will be carried out in the following areas: AREA 1: This area is bounded by straight lines joining the following co-ordinates (WGS 84 Datum) from (A) to (D) and the adjacent shoreline: (A) 22� 12.877'N / 114� 01.508'E (B) 22� 13.056'N / 114� 01.346'E (C) 22� 13.124'N / 114� 01.432'E (D) 22� 12.973'N / 114� 01.569'E AREA 2: This area is bounded by straight lines joining the following co-ordinates (WGS 84 Datum) from (E) to (H) and the adjacent shoreline: (E) 22� 13.562'N / 114� 01.052'E (F) 22� 13.511'N / 114� 01.111'E (G) 22� 13.466'N / 114� 01.061'E (H) 22� 13.532'N / 114� 01.013'E The works will be carried out by one derrick barge and one wooden boat. Some tugs and some 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 and radar reflectors will be laid to mark the positions of the anchors extending from the working vessels. Yellow marker buoys fitted with yellow flashing lights will be attached to the concrete blocks laid on the seabed at approximately 50 metres intervals to indicate the positions of the concrete blocks. Each concrete block is a 0.21 metre height pyramid shape structure with a square base of 0.5 metre by 0.5 metre. Upon completion of the drilling of the pilot hole, the submarine tracking cables together with those concrete blocks will be removed from the works areas. The hours of work will be from 0800 hours to 1800 hours. No works will be carried out on Sundays and public holidays. Vessels employed for the works will stay in the works areas outside 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 at slow speed, bearing in mind there are divers working in the areas.
