The source of the TASS agency in the emergency services said that the workers who had fallen as a result of the incident in the Kola Bay were saved.

The representative of the Zvezdochka Center for Ship Repair, Yevgeny Gladyshev, called the preliminary reason for the “unsuitable immersion” of the floating dock PD-50, in which the aircraft-carrying cruiser Admiral Kuznetsov was under repair.

According to Gladyshev, the reason for the “unsuitable immersion in water” of the floating dock PD-50 was the shutdown of pumps caused by a surge in the electrical network on the shore during the operation of “Admiral Kuznetsov” on the water, reports TASS .

According to incoming information, power outages in a number of areas of Murmansk occurred due to bad weather, which caused accidents on power lines.

The representative of the Ship Repair Center has not yet been able to clarify whether the dock is damaged.

According to a source in the emergency services, the launch of the aircraft-carrying cruiser from the floating dock was planned, the towing of “Admiral Kuznetsov” to the regular parking place at the 35th ship repair plant in Murmansk was being prepared.

Meanwhile, the medical unit "Sevryba" reported that two of the four victims of the flooding of the floating dock independently went home, another one in intensive care.

The crane, which fell from the sunken afloat PL-50, damaged the hull and takeoff deck of the aircraft carrier Admiral Kuznetsov. This was announced by the head of USC.

At the same time, the TASS source in the operational departments clarified that "the fallen crane is still there, the scale of damage is being clarified."

According to the agency interlocutor, divers will inspect the underwater part of the aircraft carrier's hull during the day to make sure that it is not damaged.

Right, that early into refit/modernization they didn't need to re-float it, so it's a mishap. Electrical power must be supplied to drydock by underground/water cables to avoid it in the future. Pathetic!
This will set back the schedule "to the right".

Gonna presumably need K out of the water to properly fix that & K doesn't fit in Severodvinsk basin so they'll have to either raise & repair or replace the dock (was built in Sweden) before they can fix K
May need a crash program to build a new floating dock if it can't be patched up.

At most it was used for pilot training but even that is irrelevant now that Russia opted for STOVL aircraft development.

I figure a floating drydock should be a pretty good candidate for building in sections elsewhere & linking together onsite.

According to ppl at Balancer these big floating docks are built with the floor in several detachable sections & maintenance is done by dropping one out & bringing it aboard the dock.

So assuming its not an outright wreck the dock could be broken into the smaller bits, each bought to the surface & repaired separately then put back together on the water (assembly from bits might not be all that easy but I feel its doable).
Sides are a single piece but being fairly simple boxes should be no big issue to cut if needed for raising & then join back together/new sections built during repair.

Edit: via BMPD comments US recently got an 80,000ton floating drydock built in China for only $40mil, apparently only took a year from order to delivery

Thats a US supplied design but I'm sure China wouldn't be above providing a slightly modified version/Russia could provide appropriate design.

Edit2: Last year Piraeus (Greece) also recieved an 80,000ton Chinese built floating dock.

Perhaps they could buy a drydock in China.

Can't Russia just build a new improved drydock? how many more decades will it take for Russia to be able to built its own shipyards/ facilities without relying on foreign products or expertise.
