Career Nizhneyansk (1983–1996) The first SA-15 class ship from Valmet, Nizhneyansk, was delivered from the Vuosaari shipyard in Helsinki on 21 January 1983, about three months ahead of the contracted delivery time. As the winter of 1983 was particularly difficult, Nizhneyansk was sent to the Northern Sea Route to unload cargo from icebound ships and deliver the much-needed supplies to isolated communities along the coast. Superior to older freighters, the new SA-15 class ships also acted as escort icebreakers, using their stern notches to tow smaller ships through the ice fields even though it was not their original purpose. The strength of the new ships was further proven when icebreaker Admiral Makarov, after having been immobilized for five days, pushed the freshly delivered Nizhneyansk at full power through the ice separating the vessels from Pevek, arriving at the city as the first ships of the year 1983. Magdalena Oldendorff (1996–2003) In 1996 Nizhneyansk was sold to a Liberian company Bandwidth Shipping Corporation, reclassified by Germanischer Lloyd and renamed Magdalena Oldendorff. Operated by a German shipping company Oldendorff Carriers, a subsidiary of Egon Oldendorff, the ship was chartered in 2000 as a support ship for the 20th Indian Antarctic Expedition. On 11 June 2002 Magdalena Oldendorff, while on her second voyage to the Maitri Base, was immobilized by pack ice. 79 Russian scientists and 11 crew members were airlifted by helicopters to the South African research ship S. A. Agulhas and returned to Cape Town. After an unsuccessful rescue attempt by the Argentine icebreaker Almirante Irízar in late August a decision was made for the ship to winter in the Bay of Muskegbukta and attempt to free itself when the ice started to melt with the beginning of the Antarctic summer. In late November Magdalena Oldendorff freed itself and returned to Cape Town in time for Christmas. Ocean Luck (2003–2010) and Captain Kurbatskiy (2010–2011) The ship changed owners again in 2003 when it was purchased by Crystal Waters Shipping and renamed Ocean Luck. The ship, managed by a Ukrainian shipping company Kaalbye Shipping Ukraine KSU, retained its Liberian registry. In 2010 the ship was purchased by its last owner, Fern Shipping, and renamed Captain Kurbatskiy. After spending a brief period of time under Cambodian flag the ship was again registered to Russia and classified by the Russian Maritime Register of Shipping.
