Well, here is a theory that the ruptures were accidental. Presented for your entertainment. No representation on my part either way. Enjoy 
The problem with sloppy work is that the supply FAR EXCEEDS the demand

Complete and utter rubbish. I posted the same in their comment section.
Half of that rant is devoted to hydrate formation. You need free water. Gas Transmission Pipelines dry the gas and even remove most all of any petroleum compounds that might form liquids and that is done before the natural gas ever gets to the first pipeline compressors. That would happen 2000 km NE of St Petersberg. Most any remaining very small amount of liquid would not make it to St Pete, but even so, liquid knockouts and filters would be there too right in front of in front of the NS compressors.
If they happen to find hydrates now, it will be because sea water entered the pipeline through the hole left by the explosions.

So you're saying the Russians could have sabotaged the pipeline by injection some water into it 2000km NE of St Petersburg?
OK you got me. Thanks. I lost focus. I didn't think of intentional accidents. Yup. Pretty dumb under the circumstances.![[blush]](/data/assets/smilies/blush.gif "[blush] [blush]")
Hydrates would probably form in the higher pressure region. If they did manage to travel such a long way and reach the 170b design pressure limited pipe, you might get a bang there. Yes. Its theoretically possible. I'll have to go back there and confess.
They might get hydrates from produced water near Yamal, especially if the treatment plant hiccups. However most all liquids would drop out before reaching St Pete, where any that didn't surely would be captured before reaching the pipeline. But that's not to say that a slug or stream of water could not have been injected into the pipeline at the pig launcher leaving the compressor station. That is definitely possible.

The remaining problems with that theory is the pipeline was supposedly not flowing, so the hydrate glob would not be making a lot of inertia forces on the bends, which have a radii in the thousands of feet range. With gas not glowing, it could not have traveled from St Pete either. And it would have to stick to the wall enough to back up pressure to build it up to 235barg to blow the 160barg design pressure section. That doesn't fit well.
Finally. You don't need to involve hydrates. Just close the outlet, turn on the compressors and put 220+10%= 244 barg in the entire pipeline. The 160 bar pipe just passed yield at around 236 barg. Maybe that's why they needed compressor maintenance a couple of months ago. Now they got it back.

Both pipes in Nord Stream 1 was turned of and I haven't been able to find out what the pressures was in them.
But there haven't been any delivery since 1 September.
Nord Stream 2 is now empty on gas according to the Danish Energy Agency.

they have just shut off the pipeline to Italy
only one left now through Ukraine.

Italy is probably going to survive off the trans Med capacity.
Spain has assurances from Algeria that supply will continue as always.
Watch for any trouble brewing in NAfrica. RU and Turkey were both going at it in Libya a few years back. Morocco and Algeria have long standing differences that Spain is trying to navigate. That seems to have improved recently, but NAfrica is NAfrica.

Exploding 1 pipe length of 42 feet with 48″diameter at 1500 psig is roughly equivalent to 124 lbs TNT and ... a 2.2 Richter event.
Has anybody seen the seismic plots?

Nothing that shows it very well.
Largest magnitud på 2,3.
Maybe here.
The Nord Stream 2 have started leaking again in the point nearest to Russia.![[ponder]](/data/assets/smilies/ponder.gif "[ponder] [ponder]")

Well zi can't read that one.
Richter 2.2 is just one pipe exploding. There should theoretically be 4 seismic events of thT magnitude, or one bigger one. Supposedly there were two explosions 17 hours apart as well.
The lone leak is weird too. Why not put all bombs at one place where you can get both pipelines?

From what I read earlier I thought there was 2 pipes in Nord stream 1 and just 1 in Nord Stream 2 but both have 2 pipes.
And it seams like one of the pipes in Nord Stream 2 which is owned 100% by Gazprom might be intact.
Coincident??
The smaller of the gas leaks are the one in Nord stream 2 pipe A, it seems this is the only one still leaking it had stopped and then is started again, no one seems to know why.

Right. Each of NS1 and NS2 have 2 pipelines. Each of the 4 pipelines has a capacity of 75E6 SCMD (2.6E9 SCFD)

Sweden is not allowing Gazprom or Russia to investigate the damage right now, since the Swedish prosecutors office decided that it is a crime scene, Danmark and Germany will as I understand it participate.
The leak in Nord Stream 2 on SE waters is still ongoing about 20 meters in diameter.
