Aleksey Chirikov icebreaker

The 2013-built MS Vitus Bering ("ледокол Алексей Чириков") is an icebreaking vessel owned by SCF Sovcomflot (Совкомфлот/fleet) and operated via the subsidiary company SCF Sakhalin Vessels Ltd. The shipowner is a Russian state-owned corporation that specializes in petroleum and LNG shipping.

The vessel (IMO number 9613551, Helsinki Shipyard/hull number 507) is currently Russia-flagged (MMSI 273369290) and homeported in Vladivostok.

The icebreaker is operated as a supply vessel for Russia's Arkutun-Dagi Oil and Gas Field (Sakhalin 1 oil field) in Okhotsk Sea, northwestern Pacific Ocean. The ship is named after Aleksei Ilyich Chirikov (1703-1748) - a Russian navigator, who together with Vitus Bering were the first Russians to reach North America during the Great Northern Expedition (aka Second Kamchatka expedition, 1733-1743). During the expedition were mapped most of Siberia's Arctic coast and parts of North America's coastline and islands.

History and construction

This Russian icebreaker class was designed by Arctech Helsinki Shipyard (Helsinki Finland) as a supply vessel, with sister ship Vitus Bering (2012-built). Both ships were ordered on December 16, 2010, following the December 10-signed agreement between the shipbuilders STX Finland (currently Meyer Turku) and OCK ("United Shipbuilding Corporation", Russia) to form the joint venture company "Arctech Helsinki Shipyard".

The shipowner Sovcomflot ("Совкомфлот"/1988-founded) is Russia's largest shipping company specializing in hydrocarbon transportation (of HGLs-Hydrocarbon gas liquids) from the Russian Arctic regions. Of the fleet's ~150 vessels, 80+ are ice-classed (with icebreaking capabilities).

Sovcomflot's shipbuilding contract value for both icebreakers was USD 200 million. Initially, the ships were scheduled for delivery both in April 2013, but Vitus Bering was delivered on December 21, 2012 (4 months ahead of schedule). This series is an upgraded version of the 2005-built SCF Sakhalin.

Most hull blocks were assembled at the Arctech shipyard, and the majority of them were manufactured in Russia (by Vyborg Shipyard). Only 5 of all the 42 hull blocks for both ships were manufactured in Finland. From Vyborg, the Russia-made hull blocks via a cargo barge were delivered to the Arctech shipyard for outfitting, painting, and assembly.

The Aleksey Chirikov ship's keel-laying ceremony was on January 3, 2012, held in Helsinki - just 3 days after Vitus Bering ship's float-out. During the ceremony, the first block (353-ton midship section) was lowered to the shipyard's covered drydock. The icebreaker was floated out on November 23, 2012. March 19-23, 2013, was the sea trials. The ship was officially delivered on April 19, 2013. From Helsinki, the icebreaker left for St Petersburg Russia.

Aleksey Chirikov icebreaker vessel details

The vessel is powered by all four Wartsila marine diesel engines (generator sets), of which two are 12-cylinder (model 12V32, combined power 12 MW) and two are 6-cylinder (model 6L32, combined power 6 MW). The ship's power plant generates combined power output 18 MW (24,000 hp). This provides electricity for all onboard systems.

The ship's propulsion is diesel-electric, consisting of two ABB Azipods (azimuth thrusters, model VI1600, combined power output 13 MW) plus 2 bow thrusters (combined power 2,6 MW).

• Max Draft: 8 m (26 ft) when fully loaded
• Deadweight: 4158 tons
• Ice-breaking capacity: 1,7 m (6 ft) - both ahead and astern ice-break capability
• Ice-breaking speed: 3 kN (5,6 kph / 3,5 mph) in ice thickness 1,5 m (5 ft)
• Endurance: 30 days
• Ice class: Icebreaker6 ( RMRS / "Russian Maritime Register of Shipping")
• Cargo capacity: cargo deck (709 m2), liquids-bulk (3850 m3)
• Crew and passenger capacity: 50 (22+28)
• Fire fighting capacity: 2 monitors (1200 m3 per hour each), water spraying capacity 1000 m3 per hour
• Rescue capacity: 195 people

Similarly designed, but with increased power (6 engines / 21 MW), larger capacity (70 people) and a moon pool (for diving support) are the SCF's icebreaking supply vessels Gennadiy Nevelskoy, Fedor Ushakov, and Stepan Makarov.

Note: In the case of poor AIS coverage, tracking the vessel's current location will be impossible. You can see CruiseMapper's list of all icebreakers and ice-breaking research ships in the "itinerary" section of our Icebreakers hub. All states and their fleets are listed there.
