As a crane technician these kinds of videos keep me up at night.
Proper maintenance and understanding of limitations goes a long way to make cranes safe.
Unfortunately plenty of people don’t care to maintain or think they know better then the computer software etc.
Some of the most unsafe cranes i have ever seen have been on board international ships as they have less stringent safety standards then anything local to Australia
Can’t park there, mate.
Special loading operation
So it was capsized by it’s own crane. That’s either bad design or operator error. I don’t know enough about how these things counter-balance to know which.
Or simply an unfinished construction that was put to active use, at least from what i could get by searching.
“Unfinished” as in “We have not installed the counterweights/ballast pumps yet”.
Cranes can generally reach well past the limit that will tip themselves over. Part of the skill when operating a crane is understanding those limits.
A good example is that when a crane is lowering its payload the length of and therefore weight of the cable increases, which can exceed the weight that the crane can support.
Yes, but how does that work on a ship?
Essentially the same way, except now you don’t even have solid ground to lever against.
A ship mounted crane is usually only going to be lifting things very close to its hull. They can’t ‘reach’ very far.
That one in the video looks like me trying to reach the TV remote on the other couch without moving my butt, and promptly falling face first into the coffee table.

So “operator error” would cover that.
What is the reason?
Internet says it was not finished yet, and being constructed by russians as cheap as possible is probably the reason the PK-700 Grigory Prosyankin capsized. It allegedly should assist in construction and loading of vessels in Severodvinsk shipyard (where nuclear submarines are constructed) - the crane is one of very few in its size class; Construction was started in 2018 but slowed to a crawl since 2020 due to financial issues. It sank during loading operations, meaning they already used their half-finished crane for years; 2 people died, and more than 20 were injured.

The front fell off
Fair enough
I don’t know the reason, but in case you didn’t know, I believe the commenter who responded to you is referencing a skit.
If you did know or I’m wrong, I apologize for wasting your time.
A skit? Is that unusual?
Oh yeah. On Lemmy? Chance in a million!
That was also a reference!
Thanks kind stranger. I know about it but many might not https://m.youtube.com/watch?v=3m5qxZm_JqM
Have a great day 😎
Should have built a jack up instead.
I’m not a boat pilot, but I’m pretty sure those aren’t built to barrel roll…
