In brief
Kapitan Khlebnikov (Russian: Капита́н Хле́бников, IPA: [kəpʲɪˈtan ˈxlʲɛbnʲɪkəf]) is a Russian (formerly Soviet) icebreaker.

In context
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 12,288 gross tons, Kapitan Khlebnikov is the 33,102nd 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 2.1 times the typical vessel on record here. The largest measures 499,167 GT.
Among the 612 research / surveys held here, it ranks 36th by tonnage — larger than 93% 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 Kapitan Khlebnikov is the 122nd 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 20 are larger by tonnage.
Kapitan Khlebnikov was built in 1970, making it 56 years old. It is one of 336 hulls in this registry delivered that year, a cohort whose median tonnage is 2,669 GT; within it this ship is the 18th largest. Across the whole of the 1970s the registry holds 17,331 vessels, median 2,774 GT. The median build year across the entire registry is 1995.
The registry attributes 118 vessels to Wärtsilä, with a median tonnage of 14,058 GT, delivered between 1938 and 1998. See the rest of that yard’s output.
At 122.5 m overall, Kapitan Khlebnikov is 51.5 m longer than the 71.0 m median for research / surveys on record, with a beam of 26.5 m and a draft of 8.5 m.
IMO numbers are issued in broadly chronological blocks. Within 500 either side of 7824417 this registry holds 41 other vessels, whose median build year is 1979 and which range from 1970 to 1981. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1970.
Its IMO number, 7824417, carries its own check digit. The first six digits are weighted seven down to two and summed — 7×7 + 8×6 + 2×5 + 4×4 + 4×3 + 1×2 = 137 — and the last digit of that total, 7, must equal the seventh digit, 7. It does, so this number is well formed.
