Britain’s Anglo-American Oil, dating from 1888, became Esso Petroleum on 6 April 1951, adopting the Esso brand introduced in 1935. It became Esso Marine U.K. in 1988 and presumably participated in the 1999 formation of International Marine Transportation. Separately, Esso International Shipping (Bahamas), formed in 1983, became Petroleum Shipping in 1994 and Standard Marine Services in 1998.
