In the early morning of September 6 local time, Gazprom (hereinafter referred to as Gazprom) issued an announcement on social media, saying that the failure of natural gas pipeline equipment of " Nord Stream-1" has the risk of fire and explosion. If the fault is not eliminated, it will affect the industrial safety of the entire station."
Regarding this explanation of Gazprom, Siemens directly responded on the same day that it said "do not understand", saying that the oil leakage of the engine of the turbine does not constitute a reason for the pipeline to remain closed, saying that "leakage can be sealed on site."
Previously, Russia announced that the Nord Stream pipeline was "completely cut off" indefinitely. For a time, European energy prices soared, and the people and various industries complained. Regarding the accusations that Russia has started an "energy war", on September 5 local time, Peskov, spokesman for the Kremlin, refuted that the delivery problem of natural gas was caused by Western countries' sanctions on Russia and should not be blamed on Russia. Peskov also said that the "technical problems" of the Nord Stream pipeline will continue until the West lifts sanctions on Russia.

Russian Gas announced on social media on September 3 that on September 3, the Russian Federation's Environmental, Industry and Nuclear Supervision Bureau (Rostechnadzor) issued a warning to Russian Gas, pointing out that the Portovia pump station of the "North Stream-1" pipeline had oil leakage of mixed sealing compounds at the cable connection terminal of the low-pressure and medium-pressure rotor speed sensor , and it must be stopped in accordance with relevant mandatory requirements. If the detected risks are not eliminated, continuing to operate the gas compressor unit will cause a risk of fire or explosion, that is, it will affect the industrial safety of the entire station.
Russian Gas announcement stated that no corresponding oil leakage was found when the unit was repaired in July, and this can also be confirmed by the act of signing the document by Siemens representatives at the scene at that time.
Russian Gas announcement stated that no corresponding oil leakage was found when the unit was repaired in July. It is worth noting that the working surface temperature of the place where the cable penetrates in the axial compressor in the gas turbine engine may reach more than 300 degrees Celsius, while the ignition temperature of the oil is about 288 degrees Celsius. A similar oil leakage occurred before, and the problem intensified and the scope expanded. "This problem on multiple equipment means that it has systematic characteristics."
Russian gas quoted the turbine manufacturer Siemens in Germany and said that oil leakage failures can only be eliminated by professional maintenance companies.
According to the relevant rules and regulations of Russian industrial safety, the operating company should meet the requirements of "preventing explosions and fires of process equipment and eliminating the possibility of explosions and fires in production buildings, structures and outdoor devices."
Therefore, it has been found that there is a risk Trent The operation of the 60 gas compressor unit (24 air pump unit) directly violates the requirements of Russian law.

According to an exclusive report by Reuters on the 6th local time, Gas deputy chief executive Vitaly Markelov told Reuters on the same day that "North Stream 1" will not resume supply until Siemens repairs the problematic equipment.

Report said that Siemens said on the same day that it did not understand Russian Gaz's statement on the current situation, saying that the engine oil leakage of the turbine does not constitute a reason for the pipeline to remain closed.
In a written statement, Siemens added, “This leakage does not usually affect the operation of the turbine and can be sealed on site”.
Previously, on September 2, after EU stated that it would limit the price of Russian natural gas, Gazprom announced that it would "completely stop" the natural gas transportation of the "North Stream-1" pipeline indefinitely on the grounds of technical failure.
Then on the 3rd, Gazette and Siemens staged a "match". Gazprom said Siemens is preparing to repair the Nord Stream 1 pipeline, but there is no place to do the work. Later Siemens denied this statement and said it was not required to carry out the work.
After Russia announced that the Nord Stream pipeline was "completely cut off", energy prices in Europe soared, causing complaints from European people and various industries.
Regarding the accusation that Russia has started an "energy war", on the 5th local time, Kremlin spokesman Peskov refuted that the problem of natural gas delivery was caused by Western countries' sanctions on Russia and that Russia should not be blamed on it. Peskov also said that the "technical problems" of the Nord Stream pipeline will continue until the West lifts sanctions against Russia.
