Scope: Angola LNG project.
Remarks: Used for Angola LNG project. May be considered to be consistent with RSAO13 / TM 12 SE (CRS code 9159) exactly at epoch 2010.90, deteriorating by 2.2cm per year. Camacupa 1948 TM 12 SE (CRS code 22092) used for geoscience in blocks awarded pre-2015.
Area of use: Angola - offshore north of 8°S - including blocks 0, 1, 2, 14, 15, 17, 18 north of 8°S and 32; onshore Soyo area.
Coordinate system: Cartesian 2D CS. Axes: easting, northing (E,N). Orientations: east, north. UoM: m.
