2 Establishment of safety zone
1 A safety zone is established around the installation specified in column 1 of the Schedule (being an installation to be stationed in waters to which subsection (7) of section 21 of the Petroleum Act 1987 applies) having a radius of five hundred metres, as respects that installation, from the point which has the co-ordinates of latitude and longitude according to the World Geodetic System 1984 specified in columns 2 and 3 of the Schedule.
The World Geodetic System 1984 (“WGS 84”) defines a reference frame for the earth, for use in geodesy and navigation. It was developed by the United States’ National Geospatial-Intelligence Agency and is maintained by it. WGS 84 is defined at paragraph 2.1 of the United States’ National Imagery and Mapping Agency Technical Report TR8350.2, third edition, amendment 1 of 3rd January 2000 entitled “Department of Defense World Geodetic System 1984” (http://earth-info.nga.mil/GandG/publications/tr8350.2/wgs84fin.pdf).
2 Paragraph (1) comes into force—
(a) on 30th January 2017, where the installation arrives at its station before that date; and
(b) when the installation arrives at its station, in any other case.
