    This is obvious incompetence. Not only was the there the high chance of killing people, but the chain was not supposed to drag along the ground
    since it could have got caught on some obstacle causing the anchor to fly off and rip up the deck railing and maybe even the joint between
    the deck and the hull. That is not a cheap, cosmetic repair.

    Russia is still afflicted by this sort of culture of shoddy workplace behaviour since the USSR period and even before 1917. Many 3rd world
    countries have similar cultural issues. But there has been substantial evolution away from this since 1991. But it will take a couple of generations
    to entrench the new culture and for the old one to finally fade away.

    We have discussed this... there is plenty of space either side for that chain to drop perfectly safely... the only way the chain could flail around dangerously is if it caught on something and there is intentionally nothing there to catch.

    BTW recently looked at a Chinese ship being launched and there were people on the slipway who had just smashed a bottle of booze on the ship as the ship will sliding down the slipway... but no mention of safety then...

    Bit unfair.

    It looks like as an accident, not a purposed early release.

    The guys in the shipyard collecting the experience at the moment.

    I can tell horror stories in British and American plants, by the way.

    Not really an accident... the release system for the chain to the anchor released too early and so the chain got dragged down the slipway, when it should have released when the anchor was released in the water to stop the vessel sailing across the water and hitting the other side.

    It really wasn't a big deal.

    The zoomed out view showed at least 5-10m between the side of the ship and the nearest people... the slipway either side of the ship had no people standing watching so that chain could drag all it wanted...

    America plans to deny Russia the North Sea Route. But Russia is the only country on the planet with a military icebreaker. The USA
    has some disintegrating rust bucket that probably would break down on the way to "enforce America's will". America is a dangerously
    pathetic joke. It is literally living off of the delusion about itself.

    American Naval officials already wanted to go up to the arctic ocean to show Russia who is boss, but the government said no because of the lack of reliable available ice breakers... it would have looked bad them steaming up there to show who is boss and having to ask the Russians to help them leave if their icebreaker fails...

    Heading for Arctic waters, 55 year old Russian icebreaker gets engine troubles off Norwegian coast


    There is stormy weather on the west Norwegian coast and the Russian icebreaker on Tuesday morning reported that it was experiencing a halt in engine power.

    The ship was located off the coast of Ålesund when the situation occured. A helicopter from the Norwegian Joint Rescue Coordination Centre quickly made it to the site, and tugboats are on their way, the rescue service informed.

    There are 33 people onboard the ship that is owned and operated by Rosmorport, the Russian state port and logistics company.

    The 84,5 meters long «Tor» is built in 1964 and has St.Petersburg as its home port. It is on its way to Sabetta, the Russian seaport in the peninsula of Sabetta.

    According to Norwegian rescue services, the ship later in the morning retained parts of its engine power and the situation is no longer consider critical, broadcaster NRK reports.

    I guess they didn't have to look for parts on e-bay as with the US icebreaker. America should not wave its dick around when its one and
    only icebreaker is old enough to have major engine failure at sea.

    Russia's Brand New Nuclear Icebreaker “Arktika” to Begin Sea Trials

    https://www.highnorthnews.com/en/russias-brand-new-nuclear-icebreaker-arktika-begin-sea-trials

    Russia’s newest and largest nuclear icebreaker Arktika will begin sea trials on December 12, announced the constructing shipyard Baltiysky Zavod. The vessel represents the first in a series of five new icebreakers to be commissioned over the next few years. The vessel’s sister ships Sibir and Ural have also been launched, with a yet-to-be-named fourth and fifth vessel ordered in August 2019.

    Sea trials will be conducted in the Gulf of Finland and will test the icebreaker’s propulsion system, communication and navigation equipment, and deck installations. Commissioning is expected for April 2020 at which point Rosatomflot, the country’s operator of all nuclear icebreakers, will take possession. The ship will operate in the Barents, Pechora and Kara Seas, as well as in shallow waters of the Yenisei estuary and Ob Bay....

    Deadline for the Viktor Chernomyrdin icebreaker to be rescheduled

    According to the newspaper Kommersant, in the material of Anastasia Vedeneeva, Viktor Chernomyrdin does not give up. The epic with the construction of the icebreaker continues ”, the deadline for the delivery of the world's most powerful diesel-electric icebreaker Viktor Chernomyrdin [project 22600] is again postponed to the first quarter of 2020. As Kommersant found out, the postponement of the deadlines for December 25, 2019 was not executed by a government decree: if the United Shipbuilding Corporation (USC) transfers the vessel to the FSUE “Rosmorport” customer now, then it will face fines and penalties of up to 1 billion rubles. At the same time, according to Kommersant, the government has so far refused to issue a new resolution on the postponement of time. In addition, Rosmorport does not want to compensate for an increase in the cost of the icebreaker by 3-4 billion rubles, which the corporation insists on.

    Motor accident on the new nuclear icebreaker "Arctic"


    According to the newspaper Kommersant, in the material of Anastasia Vedeneyeva and Ilya Usov, Arktika is losing power. Nuclear-powered icebreaker may be commissioned with a faulty engine ”, one of the propeller electric motors at the Arctic nuclear icebreaker undergoing testing after the breakdown on February 4 was recognized as non-recoverable. This means that the icebreaker, apparently, will have to be docked to replace the engine, which can take at least six months. According to Kommersant’s information, “Rosatom”, in order to avoid prolonged shutdown of the vessel, is considering the option of accepting it with a faulty engine under the shipyard’s obligation to carry out repairs. Then the capacity of the Arctic will temporarily decrease by one third, to 40 MW.

    The rowing electric motor (GED) on the right shaft of the Arktika nuclear icebreaker, which broke down in early February during mooring trials, apparently cannot be restored, sources told Kommersant. This is confirmed by the brief information prepared following the results of the meeting of the expanded commission of February 14 (Kommersant has a copy). So, representatives of the Leningrad Electric Machine-Building Plant (LEZ, part of Ruselprom) said it was impossible to restore the operability of the nose winding of the engine (four out of six phases were damaged), the document says. Representatives of the Central Research Institute of Marine Electrical Engineering and Technology (Central Research Institute of Electric Networks, part of the Krylovsky State Research Center), who were involved in the development of the electric propulsion system, believe that the incident was caused by the marriage of the engine. However, in the LEZ (supplier of the HED) the voltage jump from the frequency converter to the HED is blamed.

    The Arctic icebreaker has three propeller shafts, each equipped with two 10 MW engines. One of them failed. Two engines on the middle shaft were successfully tested before an incident occurred on February 4 with the HED on the right shaft (see Kommersant on February 10).

    If the engine cannot be repaired on board, which now seems most likely, it will be necessary to replace the icebreaker in the dock and open the hull for replacement, which will lead to a significant delay in the delivery of the vessel.

    On February 13, the head of the United Shipbuilding Corporation (USC) Alexei Rakhmanov did not directly answer Kommersant’s question whether it is really impossible to fix the engine on board. He only emphasized that the “Arctic” was “a research project, a leading steamboat; this did not exist in the world.” “Nothing catastrophic happened. You can do certain work on board, you can do certain work on the dock, we have all the technological moves written down: we understand what we will do in case A, B, C, ”Mr. Rakhmanov assured. He added that he does not yet see the risks of delaying the transfer of the icebreaker, scheduled for May. In "Rosatom", "Ruselprom" and Krylovsk State Scientific Center until the findings of the commission did not comment on the topic.

    According to the source of “b” in the industry, if the cause of what happened was a power surge, this calls into question the correct design of systems. Power surges regularly occur during operation, especially in harsh Arctic conditions, he notes, and frequency converters and fuses are installed to compensate for them. Another interlocutor of Kommersant emphasizes that there are fuses, but they did not save the GED.

    One of Kommersant’s sources notes that they have not yet given up their hopes of restoring the GED without cutting the building, and additional experts have been specially involved for this. But another interlocutor claims that the damage of the four phases out of six is ​​very significant: "Most likely, it is pointless to talk about restoration, you need to change the engine, taking into account that the ED housing is not removable, you can not open it and put a patch on it."

    According to Kommersant’s interlocutors in the industry, it can take 12–18 months to create a new GED, although theoretically engines that are designed for the following serial icebreakers can be used.

    In any case, the replacement of the GED will require considerable time, Kommersant's interlocutors talk about 6-18 months.

    However, a number of Kommersant sources do not exclude the possibility that Rosatom may accept an icebreaker with a faulty right GED. Such a solution will also require reducing the load from the left screw, that is, the power will temporarily be 40 MW. Perhaps a legal compromise will be found, and the icebreaker will be accepted under the obligation to eliminate the malfunction in the future, one of Kommersant’s interlocutors notes, otherwise the Arctic will stand for a year by the wall. According to Kommersant’s sources, the test program is ongoing at the icebreaker, despite the breakdown.

    It may well be taller, but just by looking it looks shorter in length than "50 years since victory". But the specs of Arktika put it at 173.3 m while 50 years since victory is put at 159.6 m. Pretty confusing.

    No doubt Lider will be the biggest thing breaking ice ever, but I was talking about comparing the length of project 22220 ships with the previous generation Arktika class ships.
