    The third nuclear-powered icebreaker of the type "Arctic" will be launched on May 25

    As representatives of the company specified, unlike the Arctic icebreaker, the “Ural” will descend from the stocks with already loaded reactor facilities and almost fully equipped with an electric propulsion system. In addition, the plant's specialists loaded the first three tiers of the superstructure. Such technological solutions can reduce the costs and time of construction of the order.

    Russia to float out universal nuclear-powered icebreaker on May 25


    Project 22220 universal nuclear-powered icebreakers are set to become the world’s most powerful icebreaking vessels

    ST. PETERSBURG, May 14. /TASS/. The Project 22220 universal nuclear-powered icebreaker Ural will be put afloat at the Baltic Shipyard in St. Petersburg on May 25, the Shipyard’s press office reported on Tuesday.

    "On May 25, 2019, the Project 22220 second serial-produced nuclear-powered icebreaker Ural will be floated out at the Baltic Shipyard," the press office said in a statement.

    Project 22220 universal nuclear-powered icebreakers are set to become the world’s most powerful icebreaking vessels. Aside from the Ural, the Baltic Shipyard is also building the icebreakers Arktika and Sibir.

    After the construction of these vessels is over, the icebreakers of this Project are due to provide for year-round shipping in the Arctic.

    AWESOME video of Arctic icebreaker operations, chiefly of the Sevmorput (nuclear bulk carrier) but also the 50 Let Pobedy (i think..)

    Brilliant photography and seamless time lapse that makes the big nuke 'breakers zip along like speedboats :-)

    I have a question. Why are russian ice breakers painted orange at their superstructure?

    My guess is to easier spot them and evade "white out"?

    You answered your own question... but obviously during night or snow storm operations they will have lots of lights operating, but the orange colour makes them easier to spot and identify hopefully in arctic conditions.

    They don't just break ice, they often lead convoys of ships through passages they create themselves so it is important for the convoy ships to be able to see them and follow them.

    Orange often used on North Sea and other rescue and supply ships and aircraft. A well proven very visible colour.

    I thought so but was unsure.

    Our own ice breaker is not orange like that. Its more red but superstructure white

    Icebreakers - Page 10 1200px-L%27Astrolabe_e_Konk-Kerne_01

    But ours doesnt lead convois. Its used at our antarctic land and islands so i guess its a bit different.

    As far as i know we have just one and not that much experience with that.

    Apparently they decided to build additional 2 of this class as well.

    Some ppl got awful close to an unpleasant encounter with early released chain on the right pale

    Edit: Arktika is delayed till May 2020 No

    Some ppl got awful close to an unpleasant encounter with early released chain on the right

    Not really... the chain on that side is the same as the chain on the close side... it is attached to an anchor that has to deploy when the ship is in the water to stop it sailing across the short stretch of water and hitting the land on the other side... releasing the chain on both sides is not a big deal because there is a gap on both sides anyway... it just looks worse on that side because of the effects of perspective.

    There is a lot of slack for the chain tied to the edge of the vessel so that when the vessel is in the water the weight of the anchor will rip the chain free to a length that will allow it to reach the bottom... it is pretty clear that the tied up chain on the right hand side gave way as the ship started to move and so the chain got dragged along the ground...

    I would say they were lucky it didn't catch on anything on the ground because nothing on the ground would have stopped the ship at that point... it would either be dragged into the water or the chain would break depending on what it caught on.

    I know what its for but look at the video, the chain very nearly lands on a couple of dock guys & its not impossible for a length to have flicked out into the crowd, particularly as you say if it'd have caught on something.

    Stupid people. If you have half of a brain you don't get that close to a ship being release like that. It's thousands of tonnes going straight that can't be stoped if anything happens.

    The thing is that if there was more chain to reach the people it still would have largely gone straight down because of gravity... more chain length would not have reached out sideways further... more chain would mean less swing and more vertical drop... the areas on both sides of the ship are cleared for this very reason I suspect... this wont have been their first ship launch...

    When you say it could have been worse... the entire length of chain slack was released so really apart from the chain snapping and flailing everywhere there is no worse case scenario...

    That second angle shows the chain just dropped vertically down and there were no people there to injure.

    If there was a fence post or something fixed on the ground right next to the boat as it went down the chain might catch on that and break sending the remaining chain and anchor flinging around in an arc that might be dangerous but the slip sides are absent of such things probably for this very reason...

    It is hard to start litigation due to personal injury in Russia.

    I found out this when I requested business insurance, to cover US /Canadian customers for tenth of value it cost three times more than for EU customers.

    Island OPV Thor is not realy an icebreaker. Other western patrol icebreakers are with their ice breaking capabilities on the level of 22120 Purga and 22100 Okean patrol ships from Russian Coast Guard. 22100 Okean is quite on the level with ice breaking capabilities and armament.

    Shipyards make their way to the icebreakers

    "Star" and the Crimean "Gulf" will fight with Baltzavod for a new order



    After the struggle for the super-powered icebreaker Leader, an order for which the Far Eastern Zvezda received, Russian shipyards begin the race for two more nuclear-powered icebreakers with a capacity of 60 MW and a cost of 100 billion rubles. As found out by Kommersant, in addition to the Baltzavod affiliated with the United Shipbuilding Corporation, which is already building three LC-60s, Zvezda and Kerch Zaliv, which is controlled by the Ak Bars group, plan to participate in the competition. The last shipyard was already considered as a contender for the construction of the “Leader”. Experts note that Baltzavod remains the most likely winner of the competition.

    Three shipyards can compete for an order to build the fourth and fifth nuclear icebreakers with a capacity of 60 MW, industry sources told Kommersant. According to them, in addition to the Baltzavod (part of the United Shipbuilding Corporation, USC), the Far Eastern Zvezda (managed by the Rosneft and Gazprombank consortium) and the Zaliv Kerch plant, which is managed by the Gorky Zelenodolsk plant, are planning to apply for the competition.


    FSUE Atomflot announced a tender for the construction of these icebreakers on July 19. The maximum contract price is 100.1 billion rubles, the deadline is December 2024 and December 2026. The application deadline is August 5, the electronic auction will be held the next day.

    The main contender for the construction of these icebreakers has always been considered Baltzavod. The shipyard is already building three LC-60s with a total value of 121.4 billion rubles. since 2012. The deadlines for the delivery of icebreakers were repeatedly postponed, according to the latest data, for the lead ship Arktika - this is the year 2020, for the first and second production icebreakers Sibir and Ural - 2021 and 2022.

    The principal decision on the construction of two more LC-60s was made at a meeting chaired by Prime Minister Dmitry Medvedev on November 28 at Baltzavod (for details, see Kommersant-SPb on December 6, 2018 ). The project will be funded under a mixed scheme - 45 billion rubles. will give the budget, 9 billion rubles - funds from Rosatom, the rest of the money will be attracted by the state corporation in banks (see “Kommersant” of May 23 and December 17, 2018). In "Rosatom" said that the contract for the construction of icebreakers need to sign before the end of 2018, it has not yet been concluded. According to Kommersant sources, the problem is connected with the justification of the costs of building ships. Now the interlocutors of “Kommersant” do not exclude that the contract can be signed only in early 2020.


    Last week, the head of the corporation, Alexei Rakhmanov, told Prime, that USC expects to get a contract before November: “We declare as part of our understanding of the value of these icebreakers and move forward.” On “Star”, “Gulf” and in “Ak Bars” they didn’t respond to the request of “Ъ”.

    Sources of “Kommersant” in the industry remind that approximately the same composition of participants was in the struggle for the super-power icebreaker “Leader”, which was eventually transferred to the “Star” by the decision of the president. The interlocutors of “Kommersant” note that the “Star” is now claiming “in general for all orders.” They also emphasize that the Kerch "Gulf", which built the nuclear lighter "Sevmorput" in 1988, and now successfully builds patrol small rocket ships and auxiliary ships for the Navy, should not be underestimated. Two years ago, on the Gulf, they confirmed their interest in building the Leader icebreaker and assured that for this purpose there are “all the necessary facilities” - a dry dock 360 meters long and 60 meters wide, a nuclear safety department, etc. But the shipyard had to dredge ( see “Kommersant” on August 31, 2017). At the same time, the interlocutors of “Kommersant” remind that when the decision was made to give the “Leader” to the “Star”, it was understood that the Baltzavod would receive two LC-60s, without which its continued existence would be threatened. At the same time, the load on the Ak Bars shipyards is also falling, and they need to fight for new orders, sources added to Kommersant.


    The head of Infoline-Analitics, Mikhail Burmistrov, says that the chosen format of the competition makes the battle for the Baltzavod difficult for the contract. The Gulf does not look like a real competitor, the expert believes, but Zvezda can claim fulfillment of the contract, although it is obvious that this will require cooperation with Baltzavod according to a scheme that is being discussed for the construction of the Leader icebreaker. The construction period now looks extremely ambitious, it will be difficult for them to withstand even the Baltzavod building the first ships of the series, notes Mr. Burmistrov, and for Zvezda these terms objectively look impracticable (especially on the third production icebreaker).

    Anastasia Vedeneyeva

    So this is for the 4th and 5th LK-60ya nuclear icebreakers (new Artika class).
    The first 3 are in various state of construction at the Baltic Shipyard.

    The Zvezda shipyard had already won a contract for the bigger LK-110Ya (Lider class) icebreaker.
    In addition the Zvezda shipyard should build some LNG icebreakers.

    https://www.kommersant.ru/doc/4033133

    Zaliv has the size for building such a vessel, but did not build anything similar in size and complexity since 1988.

    Probably the contract will stay with the baltic shipyard, and it is possible that the competition has been opened only for transparency reasons and to push the shipyards for a more efficient work.

    Even if the Baltic shipyard should lose the contract for the last two artika class, it would not be that critical for them.

    They would have the resources to start construction of the Leader class nuclear destroyer/cruisers. Laughing

    Afterall, the whole lot of Kirov class battlecruiser has been built there.

    The Baltic Shipyard won the tender for the construction of the fourth and fifth icebreakers of project 22220.

    Baltic plant will continue to build icebreakers of project 22220

    August 6, 2019 

    The Baltic Shipyard won the tender for the construction of the fourth and fifth icebreakers of project 22220. This is reported by the UIS in the field of procurement.

    The cost of the work will be 100 billion 58 million 690 thousand rubles. It should be noted that the enterprise did not have competition - it became the only participant in the competition.

    At present, the Arctic, Siberia, and Ural icebreakers are at different stages of construction.

    Icebreaker "Ob" went to the test

    According to PJSC Vyborg Shipbuilding Plant (Vyborg, part of the United Shipbuilding Corporation), on September 5, 2019, the port icebreaker of Aker ARC 124 Ob project (serial number 232), built at the order of Atomflot, was set off at the enterprise for sea trials in the Baltic Sea During the tests, the correspondence of the real parameters and capacities of the vessel to the design characteristics, the reliability of the equipment and ship systems will be checked.

    The vessel was built under the technical supervision of the Russian Maritime Register of Shipping under the class Icebreaker 7.

    A port icebreaker with a capacity of about 12 MW with an innovative traffic system will provide navigation for LNG tankers on the approach channel and in the water area of ​​Sabetta port on the Yamal Peninsula. A distinctive feature of the vessel is an innovative propulsion system consisting of four 3-MW propeller-steering columns. The helical columns are located in pairs in the bow and stern of the vessel, which makes it possible to work as efficiently as possible in the ice both stern and bow, maneuver and perform special tasks in the water area of ​​the port of Sabetta, where the construction of a natural gas liquefaction plant is currently underway the Yamal LNG project.

    The ship was laid down on September 27, 2016. Launching took place on June 21, 2018.

    Technical characteristics of the vessel:

    Total length - 89.2 m

    Width - 21.9 m

    Draft - 7.5 m

    Power - 12 MW

    Ice penetration - 1.5 m

    Class - Icebreaker 7

    4 propulsion azimuth installations of the Azipod type with a capacity of 3 MW each


    On the part of bmpd, we recall that the contract for the construction and delivery of the Atomflot FSUE port icebreaker of the Aker Arc 124 project was concluded by PJSC Vyborg Shipyard on April 30, 2015. At the same time, the contract deadline for the delivery of the icebreaker was November 2018.

    The icebreaker's technical design was developed by the Finnish design bureau Aker Arctic Technology Inc. The design documentation was prepared by the Balsudoproekt Design Bureau with the participation of Vympel Design Bureau JSC. The laying of the vessel in Vyborg took place on September 27, 2016, the icebreaker was transferred to the Atlant self-loading barge in August 2017 and launched on June 21, 2018.

    The vessel has an ice class of RMRS Icebreaker 7 IACS Polar Class 3. The power of the icebreaker will allow it to operate efficiently in ice 1.5 meters thick at a speed of 2 knots and develop a speed of 4 knots in broken ice up to 5 meters thick.

    In 2012-2016, by order of FSUE “Rosmorport”, three modern linear diesel-electric icebreakers “Vladivostok”, “Murmansk” and “Novorossiysk” of project 21900M with a capacity of 18 MW were built at the Vyborg Shipyard. Icebreakers have proven themselves well during operation under various conditions, including in the Arctic seas, showing their high efficiency and reliability. During the period of full-scale ice testing of vessels, indicators were achieved, including ice penetration, exceeding the calculated ones. This allowed to update the project 21900M.

    It is planned to build a new icebreaker of project 21900M2 on the basis of project 21900M and a draft design of an icebreaker developed by JSC Vympel at the expense of Rosmorport own funds, taking into account modern international convention requirements, including the reduction of harmful emissions from ship engines. The ice class of the new ship will be upgraded to Icebreaker7.

    Specifications:


    Vessel Class - KM Icebreaker7 [2] AUT1-ICS FF2 EPP ECO BWM
    HELIDECK Special purpose ship
    The greatest length - 119.8 meters
    The greatest width - 27.5 meters
    Draft - 8.5 meters
    Speed ​​- 17 knots
    Displacement - 14,300 tons
    Power on screws - 18 MW


    Comment bmpd. Thus, Leningrad Shipbuilding Plant Pella OJSC (Otradnoye, Leningrad Region) unexpectedly for all participants in the shipbuilding market received a contract from the FSUE “Rosmorport” for the construction of the first of two modified linear diesel-electric icebreakers of project 21900M2 for the Far East (and, obviously, will receive contract for the construction of the second one) - despite the fact that three icebreakers of Project 21900M for the North were previously built at Vyborg Shipyard PJSC.

    This was due to the fact that Pella was the only bidder to submit an application for the Rosmorport tender announced in August 2019 for the construction of icebreakers of project 21900M2, and on September 4 it was naturally recognized as the winner of the tender.

    At the same time, Pella, at its main site in Otradnoye, does not have sufficient capacity for the construction of such large vessels as the icebreakers of Project 21900M2. Therefore, in all likelihood, the actual construction of the icebreakers will be carried out at the German company Pella, the Pella Sietas shipyard in Hamburg (the former shipyard JJ Sietas KG Schiffswerft GmbH u. Co., existing since 1635 and acquired by Pella in bankruptcy in 2014 year). Hamburg Shipyard has the ability to build ships up to 180 meters long and 40 meters wide, with a dry dock of appropriate sizes.
