La Noumbi is a floating production storage and offloading (FPSO) unit operated by Perenco. The vessel, converted from the former Finnish Aframax crude oil tanker Tempera by Keppel Corporation, will replace an older FPSO unit in the Yombo field off the Republic of Congo in 2018.

Built at Sumitomo Heavy Industries in Japan in 2002, Tempera was the first ship to utilize the double acting tanker (DAT) concept in which the vessel is designed to travel ahead in open water and astern in severe ice conditions.[4] Tempera and her sister ship Mastera, built in 2003, were used mainly to transport crude oil, year-round, from the Russian oil terminal in Primorsk to Neste Oil refineries in Porvoo and Naantali. In 2015, Neste sold Tempera to the oil and gas company Perenco for conversion to an FPSO.
