Russia to stop gas supplies to Europe (1/4/22)

I don't want to sound like a conspiracy theorist, but Biden did say this.


You only have to listen for a minute or so before he says that America can and will stop Nordstream2 if Russia invades Ukraine.

subsea infrastructure is very vulnerable. We had a case where a ship failed to notice that it's anchor had run out and was dragged the length of the mediterranean, taking out a couple of fibre optic cables...

The big one is the transatlantic internet lines.

I bet NATO is watching them carefully.

They are very long, I'm not sure you could do a great deal against a submarine launched AUV. Once they are off the continental shelf, they are very deep and a conventional submarine couldn't get down there...

Via the industrial revolution and the green revolution in agriculture we swapped one sort of fragility for another, while increasing the carrying capacity for number of humans on the planet in a rather big way. During the long period where things were on the way up in terms of ability to extract ever more fossil fuels per day, the obvious fragility was somewhat limited by the upwards march of 'progress', but this century is far messier as we hit certain limits, where the 'low hanging fruit' in terms of huge scale resource exploitation is running out, and we face an unavoidable transition due to both fossil fuel supply realities and climate change. The transition exposes much of the underlying risk, including political and peace fragility.

There's no way it was the Russians, then. The order would have gone down the chain of command and the Danes would have been alerted by a faint oinking in the pipelines.
 
It's a result for Ukraine. There will be less chance of backsliding from Germany as the energy crisis hits their industry in the coming months. No benefit to pushing for a negotiated settlement as it can't now lead to resumed flows of gas to German factories (as the pipelines are down).
 
Russia has suspended a gas supply to Italy due to issues where the pipeline crosses Austria.

Russia's Gazprom halts gas supplies to Italy due to Austrian 'regulatory changes'

Italy's Eni is to receive no Russian gas on Oct. 1 after state-controlled Gazprom said it would not be possible to flow volumes via Austria due to regulatory changes in the country.

In a statement, Gazprom said the transportation of Russian gas in Austria had been suspended due to the refusal of the Austrian pipeline operator to confirm nominated volumes.
"The reason is related to the regulatory changes that took place in Austria at the end of September," Gazprom said. "Gazprom is working on solving the problem together with Italian buyers."
Earlier Oct. 1, Eni said it had been informed by Gazprom that the Russian company was unable to confirm the gas volumes requested for Oct. 1 as it was "not possible" to supply gas through Austria.
"Therefore, today's Russian gas supplies to Eni through the Tarvisio entry point will be at zero," the Italian company said. "Eni will provide updates in case supplies will be restored."
The halt in deliveries is the latest disruption to Russian gas flows to Europe after supplies were already halted via the Yamal-Europe and Nord Stream pipelines earlier this year and deliveries via Ukraine sharply curtailed.
Eni had been importing all its Russian gas via Austria and the Tarvisio entry point on the Austrian-Italian border since Nord Stream flows were halted completely at the end of August.
Russian gas imports at Tarvisio have been volatile in recent months and averaged around 15 million cu m/d in September, according to data from S&P Global Commodity Insights.
Russian gas to Italy is delivered via the Velke Kapusany interconnection point on the border between Ukraine and Slovakia before entering Austria at Baumgarten from where it is carried in the TAG pipeline to Tarvisio.

Price discount​

Italian gas prices have been trading at a discount to prices in northwest and eastern Europe in recent weeks thanks to an increase in imports of gas from Algeria.
Platts, part of S&P Global, assessed the Italian PSV month-ahead price at Eur148.75/MWh on Sept. 30, a discount of Eur15.75/MWh to the equivalent TTF price.
European gas prices slumped on Sept. 30 despite the ongoing uncertainties over the alleged sabotage of the Nord Stream and Nord Stream 2 pipelines and concerns that Gazprom could soon halt all remaining Ukrainian transit.
Month-ahead prices at certain hubs in Europe are now trading back below Eur100/MWh, including the LNG-rich hubs in the UK, France and Spain.
Eni -- one of the EU's biggest buyers of Russian gas -- had already seen its imports of Russian gas curtailed due to the falls in flows via Nord Stream over the summer.
Italy had also been one of Russia's biggest gas export markets, with supplies totaling 29 Bcm in 2021.

looks like it broke a weld cleanly from the inside ?
It would presumably have need shaped charges to do it from the outside ?
EDIT:- or just a factor of turning off the gas and ending up with air in it ?
