The head icebreaker of the 22220 Arctic project completed the first test phase

The main nuclear-powered icebreaker Arktika of the 22220 project successfully completed the first stage of sea trials. This was reported by the press service of the Baltic Plant (St. Petersburg).

Reaching the first stage of the factory sea trials last Thursday, December 12, the Arctic icebreaker successfully completed testing in the Gulf of Finland and on December 14 returned to the outfitting wall of the Baltic Shipyard.

The test program of the first stage has been successfully worked out: the move from backup diesel generators has been checked, independent speed in 6 units has been achieved. Icebreaker communications, navigation and home systems have also been shown to be successful.

- stated in the press service, adding that the next phase of testing will begin next year.

Earlier it was reported that the first stage of testing the icebreaker "Artika" will be held in emergency mode, without the use of a nuclear reactor. The reactor will be launched after the end of the first stage of testing; the icebreaker will enter the second stage already at the main propulsion system.

The Arctic nuclear icebreaker is the lead ship of the 22220 project in a series of three vessels being built at the Baltic Shipyard in St. Petersburg under a contract with Rosatom. The end of the tests and the transfer to the customer is scheduled for May 2020 of the year.

A feature of the 22220 project icebreakers is the use of variable draft using ballast tanks. Double-deck ships can operate both in deep water and in shallow water in river beds, overcoming ice up to 3-meters thick without losing speed. According to project data, new icebreakers will become the largest and most powerful in the world.

The main power plant of icebreakers includes two "Rhythm-200" reactors with thermal capacity of 175 MW each. Its main advantage over other similar installations lies in its compactness and economy, as well as energy-efficient integrated layout.

Good Ship! We are waiting for the launch of the Reactors and passing the full tests! Success to the Ship and Crew!

... In 2015, the Commander of the Coast Guard P. Tsukunft, when asked about the rivalry between Russia and the United States in the Arctic, said: "Today we are not even in the same league with Russia." He was mistaken, Russia is not included in any "league", Russia is the most powerful Arctic power in the world. On the water of the "league" to him to Canada, Sweden, Finland, Denmark ....

Where are they licking?

[Sergej1972]

Arctic countries Russia, Canada, Denmark (Greenland), Norway, Iceland. Finland and Sweden are not on this list.

The main power plant of the icebreakers includes two Ritm-200 reactors with a thermal capacity of 175 MW each. (from text) Total: 350MW !!! More than impressive! Let me remind you that the power of the largest aircraft carrier in the world (Enterprise) is "only" 210 MW .. They also say that Russia cannot build aircraft carriers. Yes, God bless them with aircraft carriers (we would have brought Kuzya to mind). We will build giant icebreakers! They will be of more use! The Northern Sea Route must be brought out to its “design” capacity.

[Dmitry Donskoy]

We really need an icebreaking fleet (half of the country lives in the north). And the aircraft carrier, if necessary, I’m sure we will build. There are no impossible tasks for us

Now this is the most important and most important task. We will lose time, we will miss the Arctic.

He has already been withdrawn from the fleet. Ford has 2 Bechtel A1B nuclear reactors of 700 MW each. Nimitsa were with reactors of 2x550 MW. Enterprises - less, but not 210 MW, but 8 pcs each 150 MW (this is 1,2 GW, if that).
Unpleasantly, but the shaft power is about 20% thermal (maximum) on ships.
From 1,5 GW on the shaft, this hovercraft icebreaker can be made ... or a glider (and what, the idea: a gliding icebreaker).

Only behind the reactor there is a turbine, and here ... the delay and “We were left with less than 20 months on the lead icebreaker, and we see today that it is very difficult for us. The plant has been operating around the clock for seven months ”- gen. director of the Baltic Shipyard Aleksey Kadilov - "as there was a problem on the third icebreaker, it still remains ... Kirovsky, today it is already clear that its obligations to supply the first turbine in December and the second in March will most likely be disrupted from two to three months from each term ". Head of the United Shipbuilding Corporation Alexei Rakhmanov - “If the Kirovsky plant allows itself to disrupt supplies, it will not do anything good for it.” So let's hope ...

Airborne icebreakers, cool same)))

Lead icebreaker of project 22220 "Arktika"

[Borik]

As the saying goes, the first one went, we are waiting for the rest, and ice is softer for them, and even smaller hummocks and seven feet under the keel. And there and not far off icebreakers such as Leader.

[asv363]

Alexey, both reactors were brought to the MCU (minimum controllable power level, <1%) in the first two weeks of November. When there is a team, the icebreaker is ready to give out full power for the second stage of sea trials.

[nPuBaTuP]

How could reactors be brought to some level if they hadn’t loaded fuel yet?

[asv363]

From an interview with Ruksha (head of Rosatomflot JSC):

- The leading nuclear-powered icebreaker Arktika is due to launch trials on December 12. What is the state of the icebreaker now? Did you manage to complete everything before sea trials?

= We loaded nuclear fuel into both reactors on the first Arctic icebreaker, we went through a physical launch, heat engineering tests. That is, the first part is completed, and at least it says that no later than May 2020 the icebreaker should be put into operation. There are problems with the energy start-up, now we even have to break the sea trials into two parts.

And yet they need them in a series of 5 units, and even three is somehow solid, and it will be calmer, as they say, if something happens.

[Chaldon48]

Maybe if everything goes well, then the series will be increased. In addition to these, military icebreakers are being built, which will regularly carry weapons on board.

And the "peaceful" icebreakers are not so harmless - the nuclear icebreaker "Lenin" in the project was equipped with a foundation, cellars and other equipment for quad 45 mm machine guns SM-20-ZIF1, and nuclear-powered icebreakers of the "Arctic" type had to carry much more powerful weapons. paired 76-mm AK-726 guns and four six-barrel AK-630.

Maybe on these, if something happens, there will be a place for "Calibers" and "Onyxes". During the war, icebreakers and even fishing seiners were armed.

[asv363]

For the 4th and 5th icebreakers of project 22220, the dates of their laying, launching and delivery to the customer are already known. Funding for all the work has also been found, soon my friend will be slightly "tender".

[Laksamana besar]

There will be five of them, the lead one and four production ones, and a contract was signed for two more at the end of August. The third serial icebreaker of the 22220 project should be delivered no later than 20 of December 2024 of the year, and the fourth - no later than 20 of December 2026 of the year. Well, plus three Leaders.

Correctly think. While the rest are being built, it’s time to put the first one for repair, two in work. And when five, then four at work. Icebreakers need to be built without stopping. There are no superfluous.

[Igorpl]

Seven feet under the keel, as they say.

[petrol cutter]

On diesels, disperse such a vessel to six knots. This is immediately a plus.
Our reservation is also not * lame * however.

[Alien From]

Ever since the days of "Lenin", the power of these giants amazed! Seven feet under the keel!!)))

[Moreno]

How warm it becomes in my soul when I read such news!

[Kirill Dou]

An excellent ship and a truly remarkable achievement of domestic industry.

[xomaNN]

The Arctic and the Northern Sea Route were ours in the days of the USSR and will be so now. And not defenseless

[lexa333]

Well done good luck.

[Al Asad]

And why are civilian vessels with such a large (compared to the warships of the post-Soviet period of Russia) laid down and surrendered like hot cakes, and warships of small and medium tonnage are built as aircraft carriers?

[Dikson]

Because the military has its own budget .. "Norilsk Nickel" actually builds its own fleet. Like other corporations .. Again, how much money goes to Syria ..
