ATLANTIC RICHFIELD CO.

The merging companies initially retained separate liveries. Loughran dates A10 to about 1966, followed by experimental A12 and A17 and selection of A18 in the 1970s. The arches were removed for a period in A30, then restored; continued use of an unchanged flag is queried. Ata’s website shows A12 with a diamond-shaped centre to its cross.

Atlantic Communicator was observed with this funnel in January 1974, its blue described as dark.

Mitchell assigns this funnel to Arco Anchorage. The flag is not provided but is assumed to apply.

Atlantic Richfield was formed in 1966 by the merger of Atlantic Refining and Richfield Oil Corporation and merged with BP Amoco on 18 April 2000. Its shipping interests included Arco Marine and agency work for Dover Tanker Corporation, previously managed by Sinclair. The group also held Australian coal interests and a stake in R.W. Miller, acquired in 1978 and later reduced.
