I love an internet…
If the pipeline is deep enough it will be a pancake now it might have compressed and be completely squishy down there.
To minimise the risk of pipe collapse during installation, buckle arrestors (pipe reinforcement) are installed at specific intervals in susceptible areas. The buckle arrestors are welded into the pipelines in those areas that are susceptible to propagation buckling, i.e., deeper sea areas.
The buckle arrestors are made of the same steel alloy as the line pipes and are equal in length to the line pipes. However, these pipes has a greater wall thickness, with machined thinner wall ends to match the adjoining line pipe.
Buckle arrestors are used along a 305 km stretch of the pipeline, and the spacing between them is 927m (equal to 76 line pipes).
Once its full of sea water its not collapsing, Shirley…
Personally, I could believe the US did it to kill any last bargaining option that Russia may have had with it. German winter gas reserves are high and I think the next day another line to Poland was opened. Ads – B have aircraft flying laps of Konigsberg so any movement would be spotted there. Biden is on record saying they have the means to do this, back in February. Its easy to pin it on Russia and get it to stick…. but this is just my way of joining the dots here and all sides closing the conversation about NS1 and 2.
We probably will never know beyond speculation and I’m thankful there are people managing the responses who are closer to the event and privy to info we don’t have…
