August 2002. She was awarded the Ship Of The Year 2002 award by the Society of Naval Architects of Japan (SNAJ). The second ship, Mastera, was delivered in the following year. Both ships were named after the company's oil products. While the price of the contract was not made public, the company later admitted that the 60–70 million euro estimate was "quite close to the truth". The ships were owned by ABB Credit, which leased them to Fortum for ten years. The leasing business was later sold to SEB Leasing. Tempera (2002–2018) Since the beginning, Tempera and Mastera were used primarily for year-round transportation of crude oil from the Russian oil terminal of Primorsk to company's own oil terminals in Porvoo and Naantali, where they have been the only ships capable of operating without delays or problems during the harshest winters. Occasionally they have carried cargoes in the Gulf of Bothnia and even outside the Baltic Sea depending on the amount of oil in the refineries' storage tanks. Tempera has also visited Murmansk, where she loaded crude oil from FSO Belokamenka. However, due to draft restrictions the ships could not carry a full cargo of 100,000 tons to the port of Naantali until April 2010 — they had to stop at Porvoo on the way and unload 20,000 tons of oil to reduce the draft of the vessel. In 2005 Fortum's oil division was transferred to the re-established Neste Oil and the management of the ships, including the double acting tankers, was handed over to a subsidiary company Neste Shipping. Throughout their career, Tempera and Mastera were the only double acting tankers operating in the Baltic Sea. While other double acting ships have been built in the recent years, the tankers operated by Neste Shipping are also the only ones equipped with a bulbous bow designed primarily with open water performance in mind — the tankers and container ships built for the Russian Arctic have a more traditional icebreaking bow due to the more severe ice conditions. On 29 May 2015, Neste announced a decision to sell Tempera to Perenco. La Noumbi (2018 onwards) In 2017, Tempera left the Baltic Sea and sailed around the Cape of Good Hope, headed for Singapore where she would be converted to a floating production storage and offloading (FPSO) unit at Keppel Corporation shipyard in 2017–2018, after which she would replace FPSO Conkouati at
