In brief
About Viktor Chernomyrdin
Viktor Chernomyrdin (Russian: Виктор Черномырдин), also known through her Russian design number Project 22600 or type size series designation LK-25, is a Russian icebreaker. Launched at Baltic Shipyard and outfitted at Admiralty Shipyard in Saint Petersburg, she is the largest and most powerful diesel-electric icebreaker built in Russia.
The construction of the 7.94 billion ruble icebreaker was awarded to Baltic Shipyard in December 2011. Initially expected to enter service in late 2015, the vessel was completed several years behind schedule and over budget. In 2017, it was announced that the unfinished vessel would be moved to nearby Admiralty Shipyard for outfitting in order to speed up the delivery. Due to a fire on board the vessel in November 2018 and a disagreement over the increased cost of the icebreaker, the delivery of Viktor Chernomyrdin was postponed to late 2020.

In context
How Viktor Chernomyrdin compares
Every figure in this section is a count, a rank or a percentile over vessels actually held in this registry — not over the world fleet, which is larger. Nothing here is estimated.
At 20,431 gross tons, Viktor Chernomyrdin is the 26,426th largest of the 84,014 vessels in this registry that report a tonnage. The median across that set is 5,994 GT, so this hull is about 3.4 times the typical vessel on record here. The largest measures 499,167 GT.
Among the 612 research / surveys held here, it ranks 14th by tonnage — larger than 97% of that group. Their median tonnage is 2,180 GT, and the largest tenth begin at 9,452 GT. The flag most often flown by this group is United States (90 ships). The yard that appears most often against it is Wärtsilä, with 36 hulls on record.
Russia is the country of registry for 2,810 vessels in this directory, of which Viktor Chernomyrdin is the 52nd largest by tonnage. The most common class under that flag is vessels this registry holds no type classification for (830 ships), and the median vessel measures 2,293 GT. Browse every ship flagged Russia.
Narrowing to both dimensions at once, this registry holds 69 research / surveys flying the Russia flag, of which 11 are larger by tonnage.
Viktor Chernomyrdin was built in 2019, making it 7 years old. It is one of 1,261 hulls in this registry delivered that year, a cohort whose median tonnage is 29,000 GT; within it this ship is the 676th largest. Across the whole of the 2010s the registry holds 20,111 vessels, median 23,456 GT. The median build year across the entire registry is 1995.
The registry attributes 43 vessels to Baltic Shipyard, with a median tonnage of 20,646 GT, delivered between 1960 and 2022. See the rest of that yard’s output.
At 142.4 m overall, Viktor Chernomyrdin is 71.4 m longer than the 71.0 m median for research / surveys on record, with a beam of 29.0 m and a draft of 8.5 m.
IMO numbers are issued in broadly chronological blocks. Within 500 either side of 9658630 this registry holds 59 other vessels, whose median build year is 2014 and which range from 2012 to 2019. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 2019.
Its IMO number, 9658630, carries its own check digit. The first six digits are weighted seven down to two and summed — 9×7 + 6×6 + 5×5 + 8×4 + 6×3 + 3×2 = 180 — and the last digit of that total, 0, must equal the seventh digit, 0. It does, so this number is well formed.
