DEADLY ROBO-PIGS ???

Size of Nord Stream blasts equal to large amount of explosive, UN has been told !!
Experts suggest maintenance robots may have planted bombs, as concern grows over methane buildup

"If this theory proves to be right, the sophisticated nature of the attack as well as the power of the blast would add weight to suspicions that the attacks were carried out by a state power, with fingers pointed at Russia. Moscow has repeatedly underlined its capability to disrupt Europe’s energy infrastructure.

On Friday, Vladimir Putin blamed the US and its allies for blowing up the pipelines, raising the temperature in the crisis. Offering no evidence for his claim, the Russian president said in a speech to mark the annexation of four Ukrainian regions: “The sanctions were not enough for the Anglo-Saxons: they moved on to sabotage. It is hard to believe but it is a fact that they organised the blasts on the Nord Stream international gas pipelines.”

Is anybody considering the fact that a pipeline rupture at 105 BAR can be quite explosive on its own?

Using brute force to break a pipeline seems unreliable to me. They're designed to withstand pressure after all. I would expect shaped charges to be used which wouldn't require much explosive at all.

 

[spsalso]

Hmmm.


Two gas lines fail about where an electric power cable passes under them.

450 KV. 600 MW. Quite a bit of energy there.

According to their estimates the explosion was about 500 meters from the cable.

The powerline was powerless, it was shut down for maintenance, so they don't know if it is damaged or not.
They are going to make measurements on Monday before it is put into operation again.

They estimated that the larger explosion was about 100 kg of TNT or dynamit not sure exactly what that can do under water?

The damage to the Nord Stream 1 and 2 pipelines must be investigated as soon as the pipes are empty of gas. And the investigation work can take several weeks. This is announced by the company consortium Nord Stream AG, which owns Nord Stream 1.

- We expect to start the investigation on Sunday or Monday, says Dimitri Smirnov, press spokesperson at Nord Stream AG.

The gas currently flowing from the damage to the lines is still constant. This is reported by the Swedish Coast Guard, which expects that the pipes will be emptied of gas sometime during Sunday. After that, Nord Stream AG expects to have ships at the locations where the leaks were discovered to begin investigating the damage.

The Nord Stream project had a budget of 7.4 billion euros when the pipelines were built, according to Nord Stream AG themselves.

- Today it is impossible to answer how extensive the damage is and whether it can be repaired, says Dimitri Smirnov, the company's press spokesperson.

“Can take a few weeks”
The consortium Nord Stream AG is 51 percent owned by Russian Gazprom. The other owners are German Wintershall Holding, German E.ON, Dutch Gasunie and French Engie. The company consortium is based in Switzerland.

The damage that occurred in the Swedish economic zone has occurred in international waters. Therefore, no permit is required from the Swedish Coast Guard for foreign ships that want to stay there.

- It is impossible to draw any conclusions before our investigations are complete. We expect it to take a few weeks, says Dimitri Smirnov.

A bit long, but just to clarify the legal parts of this, going forward.

Sweden and Russia can be forced to cooperate in the investigation of the gas leak.

But how the investigation is to be led - and above all by whom - may be the next difficult question.

The eddy currents around Nord Stream are expected to cease from Sunday and it will then be possible to examine the site more closely to see what has happened.
But finding evidence at the scene can be difficult – and connecting it to a person or actor can be even more difficult.
In addition, there is now a risk of disputes surrounding the investigation between the countries involved.

The area where the gas pipelines have been damaged is part of Sweden's economic zone and continental shelf, but not part of Swedish territory.
If it had happened in Swedish territorial waters, Sweden would have had an exclusive right to investigate the incident.

- As a coastal state, you have exclusive rights for decisions that, for example, can affect the environment or fishing in the area, but this does not normally include gas pipelines.
Although what has occurred affects the environment, it does not have the same devastating effect as an oil leak of this size would have had, says Paula Silfverstolpe, who is a university lecturer in international law at the Department of Political Science and Law at the Norwegian Defense University.

Since Nord Stream is owned by a consortium, an association of companies, where the main owners are the state-owned Russian gas company Gazprom, Russia also has the right to investigate the incident.

- In terms of the law of the sea, you have the right to lay pipes like this on another state's economic zone and continental shelf.
That right also includes maintaining, investigating, repairing and monitoring the functionality of the management. So it is not entirely unthinkable that we will soon see some kind of presence on the site from the Russian side, she says and continues:

- One can imagine that ships from Nord Stream appear, escorted by Russian state ships, and want to investigate the incident, which they have the right to do.
Russian state ships cannot be prevented in the area as the area constitutes international waters.
Swedish navigation warnings would not legally stop such presence.

Risk of disputes surrounding the investigation
Sweden has not formally established any classification in the case, but the government has said that it is suspected of gross sabotage.
The Russian security service FSB has stated that they have opened investigations into international terrorism.

- In any case, Russia outwardly pretends to be as surprised as everyone else, says Paula Silfverstolpe.

From the Swedish side, it may be argued that it is an attack that tried to damage Swedish interests.
It may be relevant to, just like Russia, start an investigation into international terrorism, but Paula Silfverstolpe believes that it can also be classified as gross sabotage that led to environmental destruction.

- If you get hold of a suspect, you have to make an assessment based on the rules of jurisdiction which country has the strongest right to handle the investigation further, says Paula Silfverstolpe.

- If that person sets foot on Swedish soil then we can prosecute that person.
But it is important to get hold of an individual in that case, there are no indications of ships or the like in the area.

But there are risks that there could be disputes about how the investigation should proceed.

- It can get chaotic. Russia may want to use its right to investigate without external interference, where they think Sweden can wait at the scene.

- There is no good dialogue today.
And it is a balancing act not to escalate the situation, while at the same time wanting to highlight.

It is likely that neither Denmark nor Sweden will want to cooperate with Russia, but will instead continue to inform the UN Security Council of what the investigation comes to.
If connections were found to a state agent, a foreign military or even a temporary individual who received a mission from a foreign state, then it can be judged that there is state responsibility.
Such disputes between states are handled in international courts, for example the International Criminal Court in The Hague.

Water transmits pressure quite well. You don't need a direct hit to damage a submarine; in ASW and horseshoes, close counts.

Einstein gave the same test to students every year. When asked why he would do something like that, "Because the answers had changed."

 

[TugboatEng]

Many anti-submarine and anti-ship weapons don't rely upon a direct hit to do their maximum damage. Torpedoes and depth charges often work by creating a cavity below the ship or submarine so that the hull is not supported and breaks under its own weight.

 

[spsalso]

Ah, it was just a coincidence that the pipe failures happened within 500 yards of the cable. This for pipes that are 800 miles long.

I s'pose.

There are 2 x 48" pipelines in each line in above map
Total capacity 55 bcm/yr apx 2.6 MMSM3/D (5BSCF/D)
The same consumption of California in 2020
It has a fibre optic cable.
Possible to use for spying.
There are no valves in the water (to operate via FOC)

In November 2015, Nord Stream found a disabled underwater drone with a small amount of explosives on the pipeline near Öland, and requested the Swedish Navy to remove it.[51][52]

Comments I see on a YT videoclip on this topic claim there were 4 US Navy warships (Kearsarge, Arlington, Gunston Hall and one other) and a currently unidentified attack submarine right at these locations not long ago.
Would suspect they expected the pipeline operator Nordstream AG to pin the ignition source for these explosions on that HV power cable crossing these pipelines. It would be interesting to hear when this 450kV HV cable was de energised.
The threat the US President made to helpless Olaf Scholz at that White House press conference in February is like that of a devout street bully who confesses to a sin before he commits it.

If the Russians blew the pipe lines, it maybe to burn the boats of those who maybe tempted to support rolling Putin to allow their cash cow to return to work. Then we might not be looking at something done recently but the result of a plan that has been sitting waiting the detonation signal if needed for years.

 

[Alistair_Heaton]

That was one of my thoughts as well verymadmac.

It could very well have been put in while being built. But that sort of falls over with NS 1.

But I certainly don't think it's definitely Russia. And even if it is Russia, it's definitely a state ordered action.

It's quite a complicated situation surrounding it with multiple parties.

I think not, but that only points more at Russia, and it's 500 meters. ;-)

What kinda maintenance have they been doing on the cable?

I do not think they have done any maintenance on the actual cable, but to the substation that feeds it, that is my assumption, can't see what kind of maintenance could be done on a cable.
The maintenance was planed in advance.
