Evpatiy Kolovrat (Russian: Евпатий Коловрат) is a Russian Navy icebreaker. The vessel was built by the Almaz Shipbuilding Company and entered service in July 2024.

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.[12] 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][13]

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.[7] The hull of Evpatiy Kolovrat, named after the 13th century bogatyr described in The Tale of the Destruction of Ryazan, was launched on 24 November 2020.[1] In August 2022, the unfinished vessel was towed to the Baltic Shipyard for the installation of its mast prior to sea trials in the Gulf of Finland in December.[14][15] Evpatiy Kolovrat was scheduled to join the Russian Navy before the end of the year,[16] but remained in Saint Petersburg until January 2023 when the vessel departed for her home port in Petropavlovsk-Kamchatsky under tow by the Russian tugboat Sarmat.[17][18][19] The six-month delivery voyage was completed in mid-July.[20] The ship was delivered to the Russian Navy on 1 July 2024 and commissioned on 26 July.[21][4][22]

There are plans to build a second Project 21180M icebreaker for the Northern Fleet following on Evpatiy Kolovrat. Service entry is envisaged for 2027.[23] The keel of the vessel, Svyatogor, was laid on 1 September 2023.[24]

Design

The 4,080-tonne (4,020-long-ton) Evpatiy Kolovrat is 82 metres (269 ft) long overall, has a beam of 19 metres (62 ft), and draws 4.6 metres (15 ft) of water.[9] The icebreaker is served by a crew of 28.[9]

Evpatiy Kolovrat features a diesel-electric power plant with two Kolomna 3-10D49 and one 4-10D49 diesel generators, each rated 3.5 megawatts (4,700 hp),[25] that provide electricity for both propulsion motors and auxiliary systems.[26] The icebreaker is propelled by three stainless steel monoblock propellers,[27] two driven by Steerprop azimuth thrusters and the third by a fixed shaft line.[28] In addition, the vessel has a 700 kW (940 hp) bow thruster.[11]

Evpatiy Kolovrat is classified by the Russian Maritime Register of Shipping with ice class Icebreaker6 which requires the vessel's hull to be strengthened for navigation in non-Arctic waters where ice can be up to 1.5 metres (5 ft) thick.[27][29] The vessel can break 1-metre (3.3 ft) with its bow and 0.64 metres (2.1 ft) when operating stern-first.[21] In open water, Evpatiy Kolovrat has a speed of 14 knots (26 km/h; 16 mph) and range 7,600 nautical miles (14,100 km; 8,700 mi).[9]
