Each of the two nord stream links consist of two pipelines. All four exploded on the same evening, in exactly one place on each. Three of the leaks are very close to each other, the fourth is within 50 kilometers from the others, along a 1000+ km long pipeline. By accident?

All relevant authorities on different sides of the conflict agree that this was sabotage.

It can be fun to stretch the imagination and construct complicated technical causes. But it should be known that this was not an accident.
