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 50,023 gross tons, SKS Morskoy Start is the 9,966th 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 8.3 times the typical vessel on record here. The largest measures 499,167 GT.
Among the 877 ro-ros held here, it ranks 43rd by tonnage — larger than 95% of that group. Their median tonnage is 7,395 GT, and the largest tenth begin at 34,011 GT. The flag most often flown by this group is Italy (62 ships). The yard that appears most often against it is Flensburger Schiffbau-Gesellschaft, with 16 hulls on record.
Russia is the country of registry for 2,810 vessels in this directory, of which SKS Morskoy Start is the 15th 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 9 ro-ros flying the Russia flag, of which none is larger than SKS Morskoy Start.
SKS Morskoy Start was built in 1998, making it 28 years old. It is one of 1,367 hulls in this registry delivered that year, a cohort whose median tonnage is 7,381 GT; within it this ship is the 144th largest. Across the whole of the 1990s the registry holds 12,006 vessels, median 4,956 GT. The median build year across the entire registry is 1995.
The registry attributes 5 vessels to Kvaerner Govan, with a median tonnage of 31,785 GT, delivered between 1986 and 1998. See the rest of that yard’s output.
At 182.6 m overall, SKS Morskoy Start is 57.6 m longer than the 125.0 m median for ro-ros on record, with a beam of 32.3 m and a draft of 8.3 m.
IMO numbers are issued in broadly chronological blocks. Within 500 either side of 9133812 this registry holds 62 other vessels, whose median build year is 1996 and which range from 1995 to 1998. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1998.
Its IMO number, 9133812, carries its own check digit. The first six digits are weighted seven down to two and summed — 9×7 + 1×6 + 3×5 + 3×4 + 8×3 + 1×2 = 122 — and the last digit of that total, 2, must equal the seventh digit, 2. It does, so this number is well formed.

Record
Events recorded against this vessel in the source, with the dates the source gives. An event with no date is listed last rather than assigned one.
Same yard, same years
No ship class is recorded for this vessel, so these are not asserted to be sister ships — they are contemporaries from the same builder, shown because that is what the data supports.
