PETROTANKERS S.A.

One funnel, noted on De Baif in the late 1960s, is grey with a narrow black top and a white panel edged blue, bearing three equal-sized red stars in a diagonal described as Pbds. The other is black with a similarly edged white panel and three red stars of descending size on a diagonal described as Pbd. Rosanoski suggests that the equal star sizes would also affect the flag, although the descriptive flag section records none noted.
