Any idea how the cutting wires work?

Same method was used raising the Kursk (Russian nuclear sub that sank).
The steel wire has many bobbins of steel threaded onto it that have
carbide fused into the surface. The wire is used like a giant band saw,
the seawater acting as an effective coolant.

Thanks. I don't think I'd want to be within a few hundred metres of that
arrangement!

They have to thread it under the wreck somehow?
