subsea infrastructure vulnerability

It seems to be a very poorly designed system.

Surely the phones should work for calls from one property on the island to another? Surely there'd be a backup satellite/microwave connection even if this has much diminished capacity...

It doesn't take much to damage them. By their size and shape most nets will just go right over them. There's always one though, or if they drop n drag an anchor...

Thuraya sat phone as back up would be my choice.

"According to preliminary results of the damage site inspection, technogenic craters with a depth of three to five metres were found on the seabed at a distance of about 248 metres from each other," Nord Steam said.

I had to look up "technogenic" and it means man made.

Would the sea bed not be sucked up by the gas rising?

Very little of it. A thin scrim laid over mud. Depending on the angle of the gas exiting it might form a scour pit but surprising how firm seabed actually is.

WASHINGTON, March 7 (Reuters) - New intelligence reviewed by U.S. officials suggests that a pro-Ukraine group - likely comprised of Ukrainians or Russians - attacked the Nord Stream gas pipelines in September, but there are no firm conclusions, the New York Times reported on Tuesday.

I continue to think that this could have been done remote from a zodiac, sidescan sonar with a towed cam/fish, energised magnet and an acoustic trigger. Prime the lot in a 12 hr window.
