In reply to aircooled :
That's my kind of engine room LOL. It actually looks somewhat similar to what I remember of the American Liberty that I was on when I was a cadet.
In the first picture the main steam line (big vertical white pipe forward and to the right) enters the steam chest on the high pressure turbine. The bar with the springs and all the pivot points are connected to individual nozzle blocks down in the steam chest. As the engineer opens the "throttle" a motorized linkage lifts the bar and opens the nozzles sequentially. The steam exits the high pressure turbine down low in the middle (another white pipe) and into the low pressure turbine on the left. Behind each of the turbines are the reduction gears, the yellow piping just above the gears is the lube oil supply piping.
The middle picture shows the main thrust bearing, that transfers the thrust from the propeller shaft to the ship's hull in the structure under the main engine and reduction gear. Inside that rounded housing there's a "kingsbury" style thrust bearing on both sides of an larger diameter area of the propeller shaft. Oil pressure keeps the shoes of the bearing from coming into contact with the rotating shaft under normal conditions, the force gets transferred through a thin wedge of oil. (All ships have these in one form or another, not unique to a steam ship.)
The last picture is the propeller shaft where it exits the hull. There's a coupling to the tail shaft under that guard and just behind that are the shaft seals that keep the seawater out. Looks like a spare bearing for the propeller shaft is stored up to the right there. Cool pictures, thanks for sharing!

So, what color is 1000 degree Fahrenheit water/steam anyway, dull red?
Yes. Glowing red is due to black-body radiation, and the color is independent of the material.

If they are in charlottown PEI today, they are.
That is the one. Got photos from PEI this morning. Safe travels! If you meet a couple called Chip and Marty, tell them their SIL says hello.

So, water glowing red is deadly hot, water glowing Cherenkov blue is also deadly hot but slower to kill you.
With all the money our government throws around at things we may or may not agree with, it seems a shame they won't offer to take this national treasure to one of the Navys mothball yards for safe keeping until a better solution is found.
In reply to Gearheadotaku (Forum Supporter) :
Is it really a national treasure, though? It's an old obsolete hulk of a ship that's been stripped. It's not like the QE2 or a ship of major significance other than the fact that it made a speed run.
I also wonder if there wouldn't be such a response if it had an " ordinary" name rather than a patriotic one.

I'm inclined to agree. Beautiful, fast ship, but she had the misfortune to come along at the tail end of the ocean liner era. She'll never have the historical significance of the Queens, Mauretania, Olympic, Normandie, etc.

It is a record setter, so there is that. But if the notes are correct, it's just an empty hull- not anything to work with. It's probably been held on to for one person wanting it.
Can't imagine a way to put new insides in it, other than somehow adapting modern ship construction techniques, including adding diesel electric propulsion.
In reply to alfadriver :
At that point, it's just a hull and some external structure. Not even the hot rod powerplant. And based on what I've read here, it's not a particularly comfortable hull to ride.

So, it's the equivalent of a hot rod that's been sitting up to its hubs in the dirt for the last few decades, but "I'm gonna fix it up someday".
And then it folds in half when the scrap truck inevitably comes to haul it away to the Granolafier.

In reply to Pete. (l33t FS) :
Looking through the wiki page had some fantastic history, but yeah more than a quite a few which were kept around so long they sank or wrecked while being towed to scrappers.
Remember those documentary films back in high school?
A Redditor took a bunch of shots of her last week with his drone. Got some really good ones:
A bunch more at this link.

Only if you bathe in it regularly. Perfectly safe to look down in the pretty blue water with a slight glow, as they are transferring fuel at a BWR reactor! The water is a huge part of the shielding. Remember, Nuclear Power, is MUCH diffent than "they" say (although Hollywood and fiction writers (including so call reporters) do like to sensationalize

You nails that one! Perfect comparison. I'da gone to see it while in Philly a couple years ago, had I know it was there, but history is in its world record.
Very well said, sir!
In reply to 11GTCS :
Thanks for all the accuracy in info! My brain hurts too much these days to remember all that, and although I had the classes, my trade was wrench puller / knuckle dragger back then. The Engine room pics did bring back some ... interesting ... memory's!
Cool stuff!

Okaloosa County buying this to sink it is comical in itself. We can't even get sidewalks along the busy stretch of highway that is the main artery of this area sandwiched between bombing range and ocean but, we can get retired ocean liners sunk for artificial reefs!
People that bike, walk, run, etc are constantly hit by motorist due to the lack of any kind of sidewalk along Highway 98. Motorcyclist are a favorite target too. I have a 4 mile commute, I would love to ride my bike or Grom to work; however, the times I've tried that were way to risky to my life.
It is a real shame that is all we can do with something like that..
