It's worth mentioning that cable breakages happen quite often; globally about 200 times per year [1] and the article itself mentions that just last year, two other cables and a gas pipeline were taken out by an anchor. The Gulf of Finland is evidently quite shallow. From what I understand, cable repair ships are likely to use ROVs for parts of repair jobs but only when the water is shallow so hopefully they can figure out whether the damage looks like sabotage before they sever the cable to repair it. Of course, if you're a bad actor and want plausible deniability, maybe you'd make it look like anchor damage or, deliberately drag an anchor right over the cables.

Cable repairs are certainly annoying and for the operator of the cable, expensive. However, they are usually repaired relatively quickly. I'd be more worried if many more cables were severed at the same time. If you're only going to break one or two a year, you might as well not bother.

This is a misleading framing. The two cables last year were not taken out by an anchor as an accident, it was literally a ship putting down its anchor just before the cable and then dragging it over the cable. In other words, sabotage. There's no point in trying to color any of this with rose tinted glasses when it's clear who's done it and why.

I don't understand. That's how I'd expect most accidents to happen. Someone decides to anchor too close to an undersea cable, the anchor fails to hold and the drifting ship drags the anchor over the cable damaging it.

I'm not saying it wasn't sabotage, but there needs to be something a bit more than that.

Source: have dragged anchors - thankfully never near undersea cables

I can only upvote. How does the anchor come into contact with the cable if not by that exact sequence of steps? The ship isn't sailing through the Gulf with its anchor down, it has to go near the cable, drop anchor then drag. Otherwise the cable and anchor will not interact. This is the only way an accident could happen (almost).

New New Polar Bear (the Nov 2023 case) was definitely sailing down the Gulf with its anchor down. Estonian defense minister stated at the time there are drag tracks in the seabed for "over 185 km".
