It is one of 1,485 hulls in this registry delivered that year, a cohort whose median tonnage is 17,188 GT; within it this ship is the 245th largest. Across the whole of the 2000s the registry holds 18,605 vessels, median 9,957 GT. The median build year across the entire registry is 1995.

The registry attributes 256 vessels to HJ Shipbuilding & Construction, with a median tonnage of 50,243 GT, delivered between 1974 and 2019. See the rest of that yard’s output.

IMO numbers are issued in broadly chronological blocks. Within 500 either side of 9275646 this registry holds 55 other vessels, whose median build year is 2004 and which range from 2002 to 2014. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 2004.

Its IMO number, 9275646, carries its own check digit. The first six digits are weighted seven down to two and summed — 9×7 + 2×6 + 7×5 + 5×4 + 6×3 + 4×2 = 156 — and the last digit of that total, 6, must equal the seventh digit, 6. It does, so this number is well formed.
