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?

No reason why it should fail dramatically.

Yeah, that's what a graphic showed.

You've got this steel cable with sharp bits on it, whirling around. What
could possibly go wrong?

The graphic didn't show how they did that bit, though.

Nothing. With the two barge system they use, the
worst that can happen is that it stops for a while.

Dig a pit either side, using an item called a "mole", burrow under the
wreck (by applying compressed air to it a weight slams back and forward
inside the mole causing it to move forward) they send this under the
wreck when it emerges in the pit at the other side the cutting wire is
attached to the air line, as the air line is pulled back through, the
cutting wire is pulled under the wreck.

OK dry land and a domestic application but it is the same idea.

How else are you going to get the tension on the cutting cable from
two vessels that are floating on the surface?
Or do you reckon they could use submarines and pull the cable
downwards.

Because that is the only viable way to get
enough force on the cable into the wreck.

What exactly is the reason in 2016 that electricity has to go on pylons through forestry land?

It it only considered fit for growing giant vegetables on, it wouldn't hurt to pipe the stuff below ground would it?

Or is it a beauty spot where cutting a trench would render the view deplorable even if they did it with a mole?

Or is it that the contract for maintenance is better?

Floats does it?

In that case why not get it down there by attaching something heavy alongside?
Steel cable for instance?

Or shipments of non-sds drills from lidl?

That's the glory of that's the story of little.

Its just basic physics. To get anything like the same force on
the cable with it above the wreck you'd need at least a pulley
etc at each side and would have to attach it to the sea bed
somehow. Much easier to do it with the cable under the wreck.

Perhaps the 10x cost of underground cables has something to do with it?

It costs about four times as much for underground cable.
And faults are harder to fix.

They used a similar system to cut the exit door (for H&S reasons) in
the bottom of the Secret Nuclear Bunker at Kelvedon Hatch.

They have to thread it under the wreck somehow?

In this case of this 10' thick reinforced concrete bunker wall, they
drilled holes through the wall at the top and bottom of where they
wanted one side of the cut to be and threaded a coated wire though and
back and around a driving wheel of one sort (there may have been an
idler pulley on the other side to start with). The wire was then
circulated till it cut though (or something like that).

The cut finish feels is very smooth (but not flat) and it's
interesting to see how accurately arranged the reinforcing rods were
and how consistent the concrete mix was. I understand it was also
'poured' in a continuous process so there were no 'joints' that could
possibly weaken the structu

You can see the 'Exit door' at 9:10 here and the pattern on the walls
where the wire 'cutter' ran. [1]

Ok this is a stone wire saw but I would imagine one for cutting
multiple materials is similar.

Note no, what anyone reasonable would call, sharp bits.

Dimension stone is cut in much the same way. Although large diamond
saws are now widely used, for the largest pieces they use a long wire.
In times past, the wire was passed through a bath of sand that acted
as the abrasive, but these days the wires have silicon carbide or
diamond-impregnated ferrules along their length. See

It's funny they look just like big bench bandsaws. ;-)

Yeah, the right hand diagram is what I believe they did on the SNB
exit.

If you were cutting a plane through a rectangular block using a 'loop'
driven from one side, I wondered how the cutting wire would cope with
the initial 'corners' opposite the driven side of the loop? Like, I
wondered if you might initially use an idler pulley (or two) on the
undriven side to initially get the wire to 'round' the corners and
then the idler could be removed and the loop drawn trough?
