Pretty sure this is the Prelude: https://www.google.com/maps/place/%EA%B1%B0%EC%A0%9C%EC%8B%9...

Great spot!

The giant pivot-hole in the bow seems to confirm, as well as the size...

And the first word of the second paragraph being "Prelude" was a pretty good clue, too.

I'm measuring 496m long, so not that many possibilities.

[nickkline]

Yeah, I measured it as well, but couldn't say for certain, so 'pretty sure' seemed like a safe modifier.

Side note: the inversion of the map was really interesting, I spent about 10min look at all the countries South to North trying to see if I could identify them.

And a little bit north you can see that big crane on a barge in the water. Very cool.

The images in the original link show that there will be a massive flare mounted on the bow.
