That swimming transgression against air quality is gone at least, and the Ukrainians are funnily not the cause, it was all self inflicted.

• first, the refit was delayed for years
• then, the largest floating drydock they had sank because of an power outage, smashing a 19m² hole into the boat with a 70 ton crane
• while they tried to fix this damage and upgrade the systems, a large fire broke out that caused 8 times the amount of financial damage the crane caused
• and then they took the 1500 crewmen and sent them to the frontline

There are currently no plans to reactivate this abomination

Late Edit: And this is the reason why OSHA and comparable institutions are important. This chain of events could have never happened in a country that takes workplace safety serious.

I am still searching for the clip of the epic sludge in some batches of fuel. it was in a live stream of the "Inside Russia" Youtube Channel, and he posts very long and exhaustive videos, so it might take me a bit to find the source i was talking about, but these clips (especially the one from the guy who used a nylon stocking to filter the fuel) are a good basis, although what that guy had in his filter was childs play to some batches i have seen which were sold on the black market.

Edit: still searching, but to recreate the needed mental image, the crap in the black market stuff is somewhat like jello with strings in it. Even if your fuel filter is capable pf dealing with the more solid stuff, the amorph crap in there will probably make it beyond that barrier and will fuck up everything regarding fuel injection that is the default nowadays.
