Tranmere Oil Terminal is situated on the River Mersey, 1.5 mi (2.4 km) south of Birkenhead. It was opened on 8 June 1960 to handle vessels of up to 65,000 tons, at two berths (North and South). It 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.
