The tanker company’s separate account gives formation in 1953, apparently as Asahi Unyu, rather than the 1957 separation. Part of the fleet appeared under Daikyo Tanker by 1978–79 and all by 1980–81. Alan Watt gives an April 1986 merger into Cosmo Sekiyu, while Lloyds names Cosmo Tanker and prints the date as “1.4.985”.
