Abu Dhabi National Tanker Co. (ADNATCO)

Brown shows A66’s white funnel band narrower than the outer green and red bands, which Rosanoski regards as suspect. The emblem is a displayed bird in yellow and brown, standing on a green lower arc edged yellow. Above it is a horizontally oval scene outlined in black: a black tanker on a brown-and-yellow sea beneath a yellow sky.

A646 comes from a starboard photograph of Al Dhabiyyah. The naturally coloured badge is an eagle surmounted by a circular seascape, with a black tanker sailing to the viewer’s left. The eagle stands on a sky-blue scroll bearing the black inscription “ATNATCO”, as transcribed in the source. A port-side photograph of Umm ad Dalkh dated 4 February 2013 shows a slightly different version: the eagle’s colouring differs and the scroll’s inscription is in Arabic.
