Mudyug icebreaker

The 1982-built MS Mudyug ("ледокол Мудьюг") is an icebreaking vessel owned and operated by Rosmorport. Rosmorport is a Russian FSUE (Federal State Unitary Enterprise) created in 2012 by the Russian Federation's Ministry of Transport.

The vessel (IMO number 8009181, Helsinki Shipyard/hull number 436) is currently Russia-flagged (MMSI 273910100) and homeported in Sankt-Petersburg.

One of the Russian icebreaker ships, Mudyug is named after an island in the White Sea. There, on August 23, 1918, was created a Bolshevik concentration camp and because of this the Mudyug island got nicknamed "the island of death".

With the purpose to find out promising foreign proposals for its Arctic icebreakers, the Ministry of Merchant Marine decided to refit the icebreaking ships Kapitan Nikolaev, Kapitan Sorokin, and Mudyug. The drydock reconstruction works were done in Emden Germany (Sorokin and Mudyug - by the Thyssen Nordseewerke company) and in Helsinki Finland (Nikolaev - by the Kvaerner Masa-Yards company). After a dry-docking time of nearly three months,

in October 1986 Mudyug left the Emden shipyard equipped with a Jastram-HSVA (nozzle system) and a Thyssen-Waas (hull form) bow. In April 1987 the icebreaker started an expedition to test its performance near Spitsbergen island (in the Svalbard archipelago, Norway). The converted vessel was able to break ice-thickness double that of a conventional shape of the bow. Its maneuverability in level ice was also perfect. The special ballast-tank system that was integrated into the new nozzle system increased Mudyug's ability to overcome long and deep ridges and also increased the cruising speed in snow-covered ice by 1/4.

Rosmorport's Mudyug itinerary program offers scientific and Arctic cruise expeditions and research voyages with departures out of St Petersburg (homeport).

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.
