At 107,849 gross tons, MSC Joanna is the 2,822nd 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 18 times the typical vessel on record here. The largest measures 499,167 GT.

The flag most often flown by this group is Liberia (498 ships). The yard that appears most often against it is HD Hyundai Heavy Industries, with 348 hulls on record.

MSC Joanna was built in 2006, making it 20 years old. It is one of 2,118 hulls in this registry delivered that year, a cohort whose median tonnage is 8,539 GT; within it this ship is the 41st 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 826 vessels to Samsung Heavy Industries, with a median tonnage of 75,201 GT, delivered between 1980 and 2025. See the rest of that yard’s output.

IMO numbers are issued in broadly chronological blocks. Within 500 either side of 9304435 this registry holds 73 other vessels, whose median build year is 2005 and which range from 2004 to 2007. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 2006.

Its IMO number, 9304435, carries its own check digit. The first six digits are weighted seven down to two and summed — 9×7 + 3×6 + 0×5 + 4×4 + 4×3 + 3×2 = 115 — and the last digit of that total, 5, must equal the seventh digit, 5. It does, so this number is well formed.
