The Belgian business was formed in 1933 as Belgian Gulf Oil by amalgamating Société Anonyme Belge d’Huiles et Vaselines and Société Anonyme pour l’Importation des huiles de Graissage. Mitchell states that it adopted the Belgulf Tankers name in 1963; it appears to have reverted to Gulf Oil (Belgium) in the late 1970s. Gulf Oil Marine Agency operated Belgulf and acted as agent for the Belgian company, while UBEM operated part of the latter’s fleet. Ships generally used Belgulf names.
