At 27,526 gross tons, «Kara Sea» is the 21,481st 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 4.6 times the typical vessel on record here. The largest measures 499,167 GT.

«Kara Sea» 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 283rd 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 144 vessels to Uljanik, with a median tonnage of 25,600 GT, delivered between 1952 and 2019. See the rest of that yard’s output.

IMO numbers are issued in broadly chronological blocks. Within 500 either side of 9149251 this registry holds 54 other vessels, whose median build year is 1998 and which range from 1996 to 2000. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1998.

Its IMO number, 9149251, carries its own check digit. The first six digits are weighted seven down to two and summed — 9×7 + 1×6 + 4×5 + 9×4 + 2×3 + 5×2 = 141 — and the last digit of that total, 1, must equal the seventh digit, 1. It does, so this number is well formed.
