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.

IMO numbers are issued in broadly chronological blocks. Within 500 either side of 9102473 this registry holds 59 other vessels, whose median build year is 1995 and which range from 1993 to 1998. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1996.

Its IMO number, 9102473, carries its own check digit. The first six digits are weighted seven down to two and summed — 9×7 + 1×6 + 0×5 + 2×4 + 4×3 + 7×2 = 103 — and the last digit of that total, 3, must equal the seventh digit, 3. It does, so this number is well formed.
