At 75,604 gross tons, Ilse Wulff is the 6,167th 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 13 times the typical vessel on record here. The largest measures 499,167 GT.

Ilse Wulff was built in 2009, making it 17 years old. It is one of 2,834 hulls in this registry delivered that year, a cohort whose median tonnage is 11,673 GT; within it this ship is the 276th 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.

IMO numbers are issued in broadly chronological blocks. Within 500 either side of 9401271 this registry holds 75 other vessels, whose median build year is 2008 and which range from 2006 to 2012. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 2009.

Its IMO number, 9401271, carries its own check digit. The first six digits are weighted seven down to two and summed — 9×7 + 4×6 + 0×5 + 1×4 + 2×3 + 7×2 = 111 — and the last digit of that total, 1, must equal the seventh digit, 1. It does, so this number is well formed.
