The Port of Immingham (Port Code:GBIMM), also known as Immingham Dock, is a major port on the east coast of England, located on the south bank of the Humber Estuary west of Grimsby, near the town of Immingham. In 2019, the Port of Grimsby & Immingham was the largest port in the United Kingdom by tonnage with 54.1 million tonnes of cargo passing through that year.
In the second half of the 20th century the port was considerably expanded beyond its locked dock, and east and west jetties; with the addition of several deep water jetties for bulk cargos: this included the Immingham Oil Terminal (1969, expanded 1994) for oil importation to the new Continental Oil and Lindsay Oil refineries; the Immingham Bulk Terminal (1970) built as a joint scheme by the National Coal Board and British Steel Corporation for coal export and iron ore import; the Immingham Gas Jetty (1985) for LPG import; and the Humber International Terminal (2000, expanded 2006) for bulk cargos. Roll-on/Roll-off terminals were first operated in 1966, and expanded within the dock in the 1990s, and outside the dock at the Immingham Outer Harbour (2006).
