Antan Oil Terminal, located south of the Calabar River in the Bight of Biafra, plays a crucial role in Nigeria's oil industry. This offshore terminal facilitates the export of crude oil from the region.

The oil production process involves platforms located several miles north of the terminal, transferring crude oil through pipelines to the Antan TMMP platform. From there, the oil is further transported to the FPSO "Knock Adoon" and then to exporting tankers via a CALM Buoy or tandem mooring method.
