    Fire breaks out during Russian nuclear sub repairs, no radiation threat

    RIA Novosti

    19:59 29/12/2011

    MOSCOW, December 29 (RIA Novosti) - A fire broke out at the Yekaterinburg nuclear submarine on Thursday during repairs at a shipyard in northern Russia, the local emergencies ministry department said.

    Fire safety violations during routine maintenance works are seen as the most likely cause of the blaze at a floating repair dock.

    "No deaths or injuries have been reported. There is no threat of nuclear pollution," the department said in a statement.

    Wooden scaffolding around the submarine caught fire, which spread to the submarine's light outer hull, Northern Fleet spokesman Capt. 1st Rank Vadim Serga said.

    "There is no possibility of fire burning through the hull and no threat to on-board equipment," Serga said.

    The K-84 Yekaterinburg nuclear submarine is one of seven Delta-IV class submarines in service, all deployed in the Northern Fleet. It carries 16 Sineva (NATO classification "Skiff") submarine-launched ballistic missiles.

    The Delta-IV class submarines are the core of the naval component of the Russian nuclear triad at present and may remain in service for another 10 years.

    When you first read about a fire on a sub, you often think the worst... am very relieved to find the fire was external.

    Wooden scaffolding setting fire to the rubberised material they coat the outside of the sub to reduce emissions of noise and to reduce the effectiveness of enemy sonar.

    That is a relief.

    Medvedev orders repair of fire-damaged sub

    RIA Novosti

    16:16 30/12/2011

    MOSCOW, December 30 (RIA Novosti) - Russian President Dmitry Medvedev has ordered the repar of a Russian submarine damaged by fire while in dry dock near Murmansk, the Kremlin said in a press release.

    The outer hull of the Yekaterinburg, a Delta-class nuclear submarine, caught fire on Thursday during repairs at a shipyard in the northwest Russian Murmansk Region, the local Emergencies Ministry department said.

    Emergencies Minister Sergei Shoigu on Friday reported that the fire has been put out. Firefighters battled the blaze for nine hours after it broke out.

    Medvedev instructed deputy prime ministers Igor Sechin and Dmitry Rogozin to take all necessary measures for the restoration of the submarine.

    Fire safety violations during routine maintenance works are seen as the most likely cause of the blaze at the floating repair dock.

    No deaths or injuries among the crew and shipyard workers have been reported. However, nine people were hospitalized due to smoke inhalation, a law enforcement source in the Murmansk region said. Two have already been discharged from hospital.

    President Dmitry Medvedev has ordered the Prosecutor General’s Office to thoroughly investigate the incident and to punish those responsible.

    The submarine’s hydro acoustic system, disabled by the fire, will need to be replaced before it is brought back into service, an expert said.

    The antennas of the submarine’s hydro acoustic system were damaged by the fire, Moscow Defense Brief chief editor Mikhail Barabanov said.

    The fire was caused when fuel and lubricants were set ablaze by welding in the system’s nose section, he said.

    The outer surface of SSBNs is covered in a thick rubber material to reduce noise, and that will burn like old tires.
    Near the nose of the sub, obviously the sonar antenna has no sound damping material over it, but likely it has ceramic or other material that is strong but is transparent to sound waves in both directions.

    If it burned for 9 hours then it is understandable that the sonar was damaged... on land if a pile of tires catches fire they normally just let it burn because it is so hard to put out.

    I did read from one source that they partially flooded the dry dock to put this fire out, but I have not seen that repeated so it might just be hearsay.

    Congrats on putting the fire out without injury or deaths.

    This is a project 667BDRM Delfin class sub, so it is worth repairing and putting back into service. (Delta IV in the west)

    Repairs of fire-damaged nuclear sub to take at least one year

    Repairs of the Yekaterinburg nuclear sub, damaged by fire while in dry dock near Murmansk, will take no less than a year, a spokesman for the Zvezdochka shipyard in Severodvinsk said.

    The outer hull of the Yekaterinburg, a Delta-class nuclear submarine, caught fire on Thursday during repairs when when fuel and lubricants were set ablaze by welding in the system's nose section. Fire safety violations during routine maintenance works are cited as the most likely cause.

    The submarine's hydro acoustic system was disabled by the fire and possibly will have to be replaced before it is brought back into service.

    "According to our specialists, the repair terms will be known as soon as the damage is assessed and when it becomes clear whether a new hydro acoustic complex is needed for the sub," Zvezdochka spokesman Yevgeny Gladyshev said. "According to our first assessments, repairs may take as long as one year."

    It is yet unclear at what facility the sub will be repaired.

    I agree, it looks bad, but that is the external rubber/synthetic material burning... and I would suspect also the sound dampening material that is several metres thick between the inner hull and outer hull also burning, but that is the front of the vessel, well away from the reactor and the missiles.

    The reports say the heat from the fire has destroyed the Sonar, and in my opinion likely also did some damage to the front sections including likely the torpedo room, but I would expect considering the fact that it is a Delta IV they will likely fix it.

    If it was a Delta III they might put it on the retirement list early.

    What a pity to see such relatively modern and important submarine like Delta 4 being burnt due to carelessness.

    Do they have a culture of safety in docks when a Nuclear submarine is going repair ? Or do they gulp few glasses of vodka before they work.

    Actually fires are a common problem in shipyards... you have probably seen people using cutting and wielding torches, or using angle grinders that send out showers of sparks.

    Normally there is only metal around so it is not really too much of an issue, but with wooden scaffolding and a highly inflammatory outer surface on the sub, they clearly should have been better prepared with fire extinguishers etc.

    Of course having said that the problem is like a car tire storage yard... when you have that much material in one place an a fire starts it is nearly impossible to put out.

    And that tire yard can burn for days or weeks or months depending on how big it is.

    I read somewhere that this fire burned for up to 9 hours and that they had to resort to filling the dock to put the fire out...

    They have had another fire with their SSBNs before... an Akula class SSBN (Typhoon in NATO speak) was being loaded with an SS-N-20 when the missile fell and burst open and burst into flames. The outer material was burned off but otherwise there were no problems. I believe that sub was hense forth know as Red October. The missile was of course without its warheads while being loaded as a precaution.

    The torpedo room was on fire. The bow of the ship is gutted.

    There were clearly no Torpedoes present on the vessel, so the destruction of the Torpedo room is less of a problem than the destruction of the sonar... which would be rather more expensive to replace.

    It shouldn't be impossible to cut off the front section and replace it... wont be cheap, but then again will be cheaper than a new sub.

    No one died, no radiation leaked... this can just be a safety reminder for shipyards everywhere.

    The sub is 27 years old, the refit was only supposed to keep it in service until 2018. It won't be cheap and it won't be done once they get around to announcing it.

    Russia’s nuclear submarine damaged by fire in a dry dock in late December will be repaired and put back into combat duty according to schedule, Russian Deputy Prime Minister Dmitry Rogozin said on Tuesday.

    On December 29, the outer hull of the Yekaterinburg Delta-class nuclear submarine caught fire during repairs at a shipyard in the northwest Russian Murmansk Region. Seven crewmembers and two rescuers were injured as they battled the fire, which was put out the following day.

    Rogozin inspected the damaged submarine on Tuesday and later told journalists that he is “now more optimistic than late last year.”

    “We have inspected the submarine, all of its compartments, and the forward compartment was damaged. We have also come to technical solutions, which would allow the submarine to be repaired and returned to the fleet in due time,” Rogozin said but did not specify the date.

    The official added that all those guilty in the incident would be named after an investigative commission completes its work.

    Military investigators already opened a criminal case under the statute “destruction or damage of military property due to negligence.”

    Fire safety violations during routine maintenance works are seen as the most likely cause of the blaze at the floating repair dock.

    The K-84 Yekaterinburg nuclear submarine is one of seven Delta-IV class submarines in service, all deployed in the Northern Fleet. It carries 16 Sineva (NATO classification "Skiff") submarine-launched ballistic missiles.

    The Delta-IV class submarines are the core of the naval component of the Russian nuclear triad at present and may remain in service for another 10 years.

    It comes down to the Sonar... it sounds like it was completely destroyed, and it will have been very expensive, but the question is do they have another sonar set from a recently retired sub that could be fitted to this sub.

    If they don't then this will not be cheap, but if they do then it might not be too much of a problem.

    It would cost $30 million just to retile the hull. It is more like $300 million to replace the bow.

    According to who?!?! The entire bow does not need replacing, as post fire pics show. Even if it, 300 million it would not cost. Rogozin denied it would even take 30 million to fix, BS or not.

    Replacing the fiber glass lower bow and a new sonar set is doable within 2012.

    The Yekaterinburg, a Russian nuclear submarine damaged by fire while in dry dock in late December, will be repaired and re-enter service in summer 2014, Russian Deputy Prime Minister Dmitry Rogozin wrote in his twitter account.

    “We plan to return the submarine to duty earlier, in summer 2014,” Rogozin wrote in his twitter account in response to a question from a blogger who suggested that the repairs would take three or four years.

    On December 29, the outer hull of the Yekaterinburg, a Delta-class nuclear submarine, caught fire during repairs at a shipyard in northwest Russia's Murmansk Region. Seven crewmembers and two responders were injured as they battled the fire, which was put out the following day.

    The repairs are scheduled to start this summer.

    We should keep in mind that the vessel was in drydock... likely for a life extension overhaul, so there were probably a few other things they wanted to do to it anyway.

    The middle of 2014 is a significant period, but not the end of the world.

    Repair, modernization of fire-damaged sub may cost $30 mln

    The cost to repair and modernize the Yekaterinburg, a Russian nuclear submarine damaged by fire late last December, could total 900 million rubles ($30 million), a representative of United Shipbuilding Corporation said on Monday.

    “Preliminary costs of repairs and modernization of the Yekaterinburg nuclear powered submarine are estimated between 600 million and 900 million rubles, depending on the price of the instruments and mechanisms that will be installed in the new hydro acoustic complex,” the USC representative said.

    Some media reports previously said the costs would exceed 1 billion rubles but Deputy Prime Minister Dmitry Rogozin denied the reports.

    Rogozin said the submarine would be repaired and re-enter service in summer 2014.

    On December 29, the outer hull of the Yekaterinburg, a Delta-class nuclear submarine, caught fire during repairs at a shipyard in northwest Russia's Murmansk Region. Seven crewmembers and two responders were injured as they battled the fire, which was put out the following day.

    There was no radiation leak because the reactors had been shut down before repairs began.

    The submarine’s hydro acoustic system was disabled by the fire and will need to be replaced before it is brought back into service.

    Delta-class submarines have an outer skin of anechoic rubber, designed to absorb sound from sonars to make the boat harder to detect, that can burn in a dry environment. The boat has a double hull of thick steel, however, which would protect its interior from external fire.

    The repairs are scheduled to start this summer.

    Exactly, they are just bundling the life extension and fire repairs into one now. Sub will be out for a number of years, but when it comes back, will be ready to go for another decade hopefully.

    After-Fire Recovery of SSBN Yekaterinburg Needs Two Years

    Repair of nuclear-powered ballistic missile submarine (SSBN) Yekaterinburg suffered fire in Dec 2011 will start on June 21 at JSC Zvezdochka Ship Repair Center and last up to the middle of 2014, reports RIA Novosti referring to a source in the shipyard.

    According to the source, SSBN Yekaterinburg (Project 667BDRM Delfin) will arrive at the yard on June 21. "Through the next two years, the sub's technical availability will be recovered; it is also planned to carry out emergency repairs of sonar system damaged by fire", reports the news agency.

    The source of RIA Novosti said that "recovery works on Yekaterinburg were supposed to start in Dec 2011, but due to the fire repair was postponed for June 2012".

    "After thorough examination of the sonar system, experts decided not to replace it but repair which is considerably cheaper", pointed out the interviewee.

    Upon termination of the all-up repairs, the sub will stay in service at least till 2018, reports RIA Novosti.

    Topwar.ru carried an Interfaks story saying Delta IV-class SSBN Novomoskovsk is nearing the end of a modernization to extend its service life to 2021. The sub went to sea for some trials last week. It is, by the way, the newest of the class. Zvezdochka is also working on Verkhoturye, and both SSBNs will reportedly return to service by the end of 2012. See this earlier-posted related item.
