Have there been shipwrecks that have been damaged by undersea communication cables (or even discovered because cables were being laid)? (lemmy.ml)

Was reading about undersea com/internet cables. Then just started thinking about how wild it would have been if a wreck like the Titanic had been messed up even more if a cable (or cables) had been dropped on it (or even found due to laying them).

I started searching, but there are too many articles about the cables being damaged and/or sabotaged. But aside from some that talk about potential impact of the environments where they are laid, I haven't seen anything about damaging shipwrecks by the cables or discovering any while being placed.

Would imagine that most of the cables are placed outside of really busy shipping routes, and avoid unnecessarily deep sections. Still would be kind of interesting to know.

I mean from what I see they are spooled off the back of ships so I think its possible as they sorta land where they will. I mean I assume the boats are charting some course that minimizes overall depth or whatnot to reduce how much and the lenght of the cables. There is way to much at stake money and performance wise not to. Likely to avoid any known dangerous things or things where the cable would damage something important. This makes me think they must all be pretty close together. Thats the thing with savatoge. requires a submarine while the laying of cable is from the surface.

Sabotage can also be carried out without submarines. For example, a ship could drag its anchor along the seabed (whether in the Baltic Sea or the Taiwan Strait) near known locations of internet cables.
