Yevpaty Kolovrat (Russian: Евпатий Коловрат) is a Russian icebreaker under construction at Almaz Shipbuilding Company for the Russian Navy. The vessel is scheduled to enter service with the Northern Fleet in 2022.

Development and construction[]

In the mid-2010s, the Ministry of Defence of the Russian Federation announced that a fleet of new auxiliary icebreakers would be built for the Russian Navy as part of the ongoing fleet renewal program to replace Soviet-era vessels.[10] However, the initial plans for the construction of four 6,000-tonne (5,900-long-ton) Project 21180 icebreakers was revised after the lead ship, Ilya Muromets, turned out to be too expensive. As a response to this, Vympel Design Bureau developed a revised design, 21180M, with about two thirds of the displacement and more limited functionality compared to the bigger vessel.[3][11]

The construction of the Project 21180M icebreaker, estimated to cost between 5 and 6 billion rubles, was awarded to the Saint Petersburg-based Almaz Shipbuilding Company in 2017[3] and the keel of the vessel was laid on 12 December 2018.[5] The hull of Yevpaty Kolovrat, named after the 13th century bogatyr described in The Tale of the Destruction of Ryazan, was launched on 24 November 2020[1] and the icebreaker is scheduled to join the Russian Navy in 2022.[4]

There are plans to build a second Project 21180M icebreaker for the Northern Fleet following on Yevpaty Kolovrat. Service entry is envisaged for 2027.[12]

Design[]

The 4,080-tonne (4,020-long-ton) Yevpaty Kolovrat will be 82 metres (269 ft) long overall, have a beam of 19 metres (62 ft), and draw 4.6 metres (15 ft) of water.[6] The icebreaker will be served by a crew of 28.[6]

Yevpaty Kolovrat will feature a diesel-electric power plant with three 3.5-megawatt (4,700 hp) diesel generators that provide electricity for both propulsion motors and auxiliary systems.[9] The icebreaker will be propelled by three stainless steel monoblock propellers,[13] two driven by Steerprop azimuth thrusters and the third by a fixed shaft line.[14] azimuth thruster and a third propeller driven by a fixed shaft line. In addition, the vessel will have a 700 kW (940 hp) bow thruster.[8]

Yevpaty Kolovrat will be classified by the Russian Maritime Register of Shipping with ice class Icebreaker6[13] which requires the vessel to be capable of operating in level ice with a thickness of 1 metre (3.3 ft) in a continuous motion and her hull strengthened for navigation in non-Arctic waters where ice can be up to 1.5 metres (5 ft) thick.[15] The vessel's speed in open water will be 14 knots (26 km/h; 16 mph) and range 7,600 nautical miles (14,100 km; 8,700 mi).[6]
