Tranmere Oil Terminal is situated on the River Mersey, 1 1⁄2 mi (2.4 km) south of Birkenhead. It was opened on 8 June 1960 to handle vessels of up to 65,000 tons, and is connected to the Stanlow Oil Refinery by a 15 mi (24 km) pipeline. Part of the terminal occupies the site of a former ferry service to Liverpool, with the extant pier considerably modified.
By 2001, the terminal had two converted crude oil tanks which could handle 30,000 t (30,000 long tons). These were used for the storage of crude oil from the Foinaven oilfield.
The terminal is operated by the Mersey Docks and Harbour Company.
