Loughran dates BP Oil’s formation to 1 January 1976, when the Shell Mex & BP coastal fleet split. Lloyd’s gives a different lineage from Anglo-Iranian Oil (China), renamed BP (China) in 1952, BP Refineries in 1968, and BP Oil and BP Oil UK in 1989. Rosanoski explicitly finds this inconsistent with the earlier register evidence and Loughran. Later vessels began with “Border”.
