Interesting choice of tourism destination, but quite cool (no pun intended...) regardless.
One of the most annoying things about working with anything metal at those temperatures, is that your tools will pretty much instantly become stuck to whatever it is you're trying to manipulate, making a propane burner an indispensable addition to your toolbox.
I saw a youtube video of a single mother who job it was to cut out the ice from underneath the ships to create space to do the repairs. Apparently its a very dangerous job because you can easily end up frozen to the river if you're not careful. Must be the same one mentioned in the article.
It's not okay to casually appreciate the vacation pictures of a corrupt Russian oligarch, even if they overlap with an area of technical interest.
Kapersky is part of a corrupt regime that has killed tens of thousands of innocent Ukrainian civilians and murdered leaders of rival political parties. You can get numb to it, but it is a horrible, historic war crime. He is complicit and his boat pictures can go to hell.
As the ice expands, I think the ship gets lifted upwards slightly. Water freezing and expanding in pipes and enclosed spaces is the real problem. There's several ways to cool a ship engine, I suspect these all use a system where the "radiator" is a hull feature where anti-freeze engine coolant goes through exposed veins in a closed loop to exchange heat with the cold water under.
Skills that aren't present in sufficient quantities for the US military to be able to invade or hold Greenland. (They have a "Space" base 1000 mi from Nuuk but it consists of 150 personnel, a 10000' runway, and facilities for missile detection.) Furthermore, the ~55k Danes and Greenlanders have 15k-20k large caliber rifles that hit out to 800-900 meters out of necessity. People there sell suppressed .30-06 and larger rifles with enormous optics on FB Marketplace for $600-800 equivalent. US invading Greenland would face 1000+ Simo Häyhäs and the dissolution of NATO.

The pictures of this technique triggers my submechanophobia - especially the photo of the two people working underneath the ship.
