RIMORCHIATORI RIUNITI INTERNATIONAL SHIPPING & INVESTMENTS LDA.
image by Jorge Candeias, 4 March 1999
The flag is a vertical green-white-red triband, with the white about half the width of either outer stripe. White RR appears on green and white ISI on red. The white stripe carries a device resembling the Portuguese arms: a yellow circular figure with openings, overlaid by a white shield bordered red. Jorge Candeias could not distinguish the shield’s interior detail in the small original image.
