Icebreaker "Arktika" will be tested "Rosatom" year

Head nuclear-powered icebreaker Arktika (project 22220) will be handed over in 2020 to the customer in the face of Rosatom in trial operation for one year, so that in 2021 the ship stood in dry docking to replace the right motor, told RIA Novosti on Monday the head of the United shipbuilding Corporation Alexey Rakhmanov.

Earlier in June, the General Director of Rosatom state Corporation Alexey Likhachev, during his working meeting with President of Russia Vladimir Putin said that the icebreaker "Arktika" on June 23, came from St. Petersburg on the final stage of sea trials. It is planned that the icebreaker in September, the deadline is in October of this year will be commissioned Rosatom.

"Icebreaker "Arktika" after the test will be delivered to the customer this year for one year for work on purpose in the Arctic, after which the vessel will return to the baltzavod to replace the right motor," - said Rakhmanov.

He recalled that only on the ship three electric motors with a capacity of 20 megawatts each.

"Now the total capacity of the Arctic is 52 MW instead of 60 given the fact that the defective winding of the right engine reduced its power to 8 megawatts," - said the head of the USC.

As reported previously, the company of Rosatom FSUE Atomflot (Rosatomflot), in February this year during the commissioning of "the Arctic" was a failure stator winding of the nose of the right propeller of the motor. Interdepartmental Commission has determined that the engine is beyond repair and requires removal. Despite this, the icebreaker will be in operation, considering the growing intensity of shipping in the water area of the Northern sea route, Rosatomflot said. A replacement propeller of the motor will be produced in the period from August to November 2021, said Rosatomflot.

According to the developer of the project of the atomic icebreaker "Arctic", "Central design Bureau "iceberg", when run without a single engine deviations from the design characteristics of a ship will be negligible, allowing the submarine to operate effectively in the Arctic. Power of the icebreaker will be about 50 MW (instead of the designed 60 MW), the loss of icebreaking capability of up to 20 inches (2.9 meters), with a speed of 0.6 knots (22 knots in clear water).

Nuclear icebreakers of the project 22220 is the largest and powerful in the world. They are necessary to ensure Russian leadership in the Arctic. The ship's length will be 173.3 m, width - 34 meters, a displacement - 33.5 thousand tons. These icebreakers will be able to conduct convoys in Arctic conditions, punching ice up to three meters. They will provide pilotage of vessels with hydrocarbons from fields in Yamal, gydansky peninsulas and the Kara sea to the markets of the Asia-Pacific region.

Head versatile atomic icebreaker LK-60Я "Arctic" project 22220 was previously built at "Baltic shipyard" in St. Petersburg, now there is a construction of two serial nuclear icebreakers "Siberia" and "Ural". In August 2019 and baltzavod Rosatom signed a contract for construction of two serial nuclear icebreakers of this project. The cost of the contract for two more vessels amounted to 100 billion rubles. Tab of the fourth universal nuclear-powered icebreaker "Yamal" was held on may 26 this year on the "Baltic plant". The customer of construction of these nuclear powered icebreakers Rosatomflot acts.
