[4] The refinery was formally opened by Stanley Baldwin, the President of the Board of Trade.

One part of the refinery was near Queen's Dock; ships came from the British Tanker Company.

In 1959 the refinery contributed financially to new building work at University College Swansea.

[14] The Angle Bay Ocean Terminal was in full operation at the end of November 1960.

[15] The terminal was officially opened on Thursday 20 April 1961 by Richard Wood, Baron Holderness, the Conservative Minister of Power.

[17] As initially constructed the refinery produced petrol, kerosene and fuel oils.

[20][21] From 1947, capacity of the site was trebled, at a cost of £9m, under chairman William Fraser, 1st Baron Strathalmond.

[23] The US Economic Cooperation Administration helped to fund this expansion, as well as the Shell Haven refinery.

[30] A ferrofiner unit, for lubricants, was developed at Sunbury, which would be built from December 1961,[31] and operating from June 1963.

Half the capacity was decommissioned in late 1985, the remainder was closed in January 1986, together with the Angle Bay terminal and pipeline.

[5] The refinery was the focus of a significant petrochemical industry in the area: the Baglan Bay complex.

[39] Crude oil was originally imported through the purpose-built Queen’s Dock at Swansea, capable of handling tankers of up to 28,000 D.W.T.

[6] To accommodate larger tankers then being developed, a new jetty below Fort Popton and a new terminal was constructed at Angle Bay in Milford Haven, Pembrokeshire in 1962.

The site of the refinery, which covered 650 acres, was off the Llandarcy Interchange (Junction 43) of the present-day M4, near the B4290 and Skewen.
