At 65,059 gross tons, Rio Barrow is the 7,054th 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 11 times the typical vessel on record here. The largest measures 499,167 GT.

Rio Barrow 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 131st 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 1,092 vessels to HD Hyundai Heavy Industries, with a median tonnage of 65,131 GT, delivered between 1970 and 2025. See the rest of that yard’s output.

IMO numbers are issued in broadly chronological blocks. Within 500 either side of 9216999 this registry holds 62 other vessels, whose median build year is 2001 and which range from 1999 to 2003. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 2001.

Its IMO number, 9216999, carries its own check digit. The first six digits are weighted seven down to two and summed — 9×7 + 2×6 + 1×5 + 6×4 + 9×3 + 9×2 = 149 — and the last digit of that total, 9, must equal the seventh digit, 9. It does, so this number is well formed.
