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. Career Since the beginning, Tempera and Mastera were used mainly 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 were the only ships capable of operating without delays or problems during the harshest winters. Occasionally they also carried cargoes in the Gulf of Bothnia and even outside the Baltic Sea depending on the amount of oil in the refineries' storage tanks. 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. On 19 September 2013, Neste Oil announced that it would sell its shipping business and the majority of its ships, including Mastera, to a new company owned by the Finnish insurance company Ilmarinen and the National Emergency Supply Agency. In 2019, Mastera was resold back to SEB Leasing. Since 2017, Mastera was the only double acting tanker operating in the Baltic Sea after Tempera was sold overseas. While other double acting ships have been built, the tankers operated by Neste Shipping were 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. In September 2021, Mastera was transferred to the Norwegian International Ship Register. In January 2022, she was renamed Mikines and reflagged to Liberia. In March 2022, the 19-year-old Mikines appeared on list of tonnage sold for demolition, but has since resumed trading and was renamed Alma in June 2022.
