At 11,320 gross tons, «Nora» is the 34,292nd 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 1.9 times the typical vessel on record here. The largest measures 499,167 GT.

Among the 604 chemical / products tankers held here, it ranks 203rd by tonnage — larger than 64% of that group. Their median tonnage is 5,979 GT, and the largest tenth begin at 25,682 GT. The flag most often flown by this group is Panama (80 ships). The yard that appears most often against it is HD Hyundai Mipo, with 35 hulls on record.

«Nora» was built in 2001, making it 25 years old. It is one of 1,268 hulls in this registry delivered that year, a cohort whose median tonnage is 14,062 GT; within it this ship is the 648th 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 18 vessels to Cantiere Navale de Poli S.p.A., with a median tonnage of 5,440 GT, delivered between 1972 and 2008. See the rest of that yard’s output.

At 138.1 m overall, «Nora» is 19.0 m longer than the 119.1 m median for chemical / products tankers on record and a draft of 9.1 m.

IMO numbers are issued in broadly chronological blocks. Within 500 either side of 9230012 this registry holds 70 other vessels, whose median build year is 2002 and which range from 2000 to 2013. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 2001.

Its IMO number, 9230012, carries its own check digit. The first six digits are weighted seven down to two and summed — 9×7 + 2×6 + 3×5 + 0×4 + 0×3 + 1×2 = 92 — and the last digit of that total, 2, must equal the seventh digit, 2. It does, so this number is well formed.
