Submerged Volvos in Halifax Harbor?

there is also a legend of a load of early p1800s and scotch whiskey that
went down in the channel in the early sixties. unconfirmed, just thought
id add that

 

The P1800s would have bought it, but the Scotch should have aged nicely.
Except it probably wouldn't be in casks -- still a thought.

Actually, I think they cut it into five or six sections. The technique
is rather simple, just on a large scale.

For something the size of the Tricolor, use an abrasive cable (flexible
steel with carbide bits bonded to it, for example) about 1500' (457m)
long and about 2" (50mm) in diameter for a vessel in 1600' (487m) of water.

Position one barge on each side of the vessel where the cut is to be
made, each barge having a large, powerful winch on board. Each winch
needs enough cable to reach to the bottom where the vessel lies. The
abrasive cable is attached to one winch and lowered until the downward
end is at the bottom beside the vessel.

The other winch lowers its' cable to the bottom, where it is passed
under the vessel (a tunnel can be dug with a pressure hose) and attached
to the free end of the abrasive cable. The first winch then pays out
cable as the second draws in, getting the abrasive cable pulled under
the vessel. Once it's through, the barges tighten the cables, then
alternate pulling and paying cable, keeping the tension on.

Eventually, the abrasive cable grinds through the hull, decking,
bulkheads, piping, cargo, and anything else in the way.

Then, someone with a big crane on a big barge gets to hoist up a few
hundred tons of scrap...

The engines driving the winches are probably diesels, which will be
pretty noisy.

Underwater, there'd be a long scraping sound, a pause, another long
scraping sound, pause, scrape, pause, scrape, etc.

Might be an occasional clanging sound when a large piece of metal
comes loose and bounces around.

IIRC, there was a load of wine and champaigne that sunk during
WWI in the hcannel that they hauled up.

The pressure had forced seawater into the wine bottles, but the
champaigne was as good as new as its pressure counteracted the
depth.

So the Scotch would be bad as well.

 

Funny, I have actually dived that wreck! It's called the Zenobia and
its full of Volvo and Scania trucks, that where headed for Africa.
It was a strange feeling to swim around inside that boat I tell you

Yeah, this is the sound that I expect could end up being heard a great
distance. Diesel noise too, of course.

The Tricolor was in shallow water; you could see the hull under perhaps
30 feet of water. This at least made it easy for the divers to work
down there. If the wreck were in deep water or outside of the shipping
lane, perhaps they would have left it there.

 

Just out of interest the wreck has been hit by at least a couple of ships
already.

Cheers, Peter.

Three or four, as a matter of fact. Two hits within about a month of
the sinking (despite being marked with a light), and another a few
months later. I'm pretty sure there was a fourth hit too.

The ship that sank the Tricolor had apparently changed course to avoid
hitting another ship...

It was mentioned on another web site whose URL I now forget.
