MT Yuriy Kuchiev

Development and construction In early 2016, it was reported that the Greek shipowner Dynacom had ordered two arctic condensate tankers to transport gas condensate from the natural gas fields in the Yamal Peninsula. One of the vessels would be built at Guangzhou Shipyard in China while the other was ordered at an undisclosed price from the Russian-owned Arctech Helsinki Shipyard. While the Finnish shipyard was initially reluctant to confirm the contract, the tanker was included in a presentation by Arctech CEO Esko Mustamäki at the Conference on the Economic Development of the Arctic in June 2016. Although over 500 vessels have been delivered from the Hietalahti shipyard in the past 150 years, the newbuilding number 515 would be the first tanker built at the shipyard. However, the official keel laying ceremony, which marks the start of hull assembly, was held in Helsinki on 27 July 2017. The vessel was launched on 17 December 2018, floated out on 28 December, and returned to the covered dry dock bow-first on 30 December. On 29 April, Yuriy Kuchiev was moved from the covered dry dock to the shipyard's outfitting pier in preparation of inclining test before leaving for the first sea trials on 6 May. The vessel was finally delivered to Dynacom in an official naming ceremony on 28 August 2019. The arctic condensate tanker Yuriy Kuchiev is the last vessel delivered by Arctech Helsinki Shipyard in Finland; the shipyard's ownership was transferred to a new company, Helsinki Shipyard Oy, in May 2019. == Design ==

General characteristics Yuriy Kuchiev is long and has a beam of , making the vessel the widest newbuilding ever delivered from Hietalahti shipyard. The length-to-beam ratio is slightly greater than that of other icebreaking tankers operating in the region, improving ice-going capability as well as allowing the hull to be assembled in Arctech's Panamax-sized dry dock. The maximum draft of the vessel, limited by the port of Sabetta in the Gulf of Ob, is . The vessel's design deadweight tonnage is 50,000 tons. Since the vessel is designed according to the double acting ship principle, the stern of the vessel is strengthened in the same way as the bow. In order to offset the increased scantlings, the hull is made mainly out of high-strength shipbuilding steel. The vessel is also thoroughly winterized for operation in ambient temperatures down to and features a covered forward mooring deck to protect the deck equipment from icing. Power and propulsion While a typical Handymax tanker would have a single conventional shaft line and propulsion power in the range of , Yuriy Kuchiev is designed to operate independently in difficult ice conditions and thus requires a specialized propulsion system as well as significantly more installed power. The diesel-electric power plant consists of two 12-cylinder Wärtsilä 12V32 and two 16-cylinder Wärtsilä 16V32 four-stroke medium-speed diesel engines driving alternators. In addition, there is a harbor diesel generator. For propulsion, Yuriy Kuchiev has two ABB Azipod VI2300 azimuthing propulsion units with stainless steel propellers. The propulsion units are of pulling type, meaning that the propeller is always facing the direction of motion: when breaking ice in astern direction (backwards), the propellers are turned around to face the stern of the vessel and help with the icebreaking process. Yuriy Kuchiev is designed to break level ice in a continuous motion with a speed of in astern direction. When sailing bow-first, the icebreaking capability is about . In open water, the vessel's economical service speed is . == Notes ==
