Oil and gas exploration and production.
Used by CABGOC for offshore areas between 1979 and 1987. Differs from Mhast (onshore) / UTM zone 32S by approximately 10m. Replaced by Malongo 1987 / UTM zone 32S (CRS code 25932) in 1987.
Angola (Cabinda) - offshore; The Democratic Republic of the Congo (Zaire) - offshore.
Cartesian 2D CS. Axes: easting, northing (E,N). Orientations: east, north. UoM: m.
