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. "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.
