Alfred N

At 131,479 gross tons, Alfred N is the 1,984th 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 22 times the typical vessel on record here. The largest measures 499,167 GT.

Among the 6,890 bulk carriers held here, it ranks 105th by tonnage — larger than 98% of that group. Their median tonnage is 32,837 GT, and the largest tenth begin at 85,849 GT. The flag most often flown by this group is Panama (1,548 ships). The yard that appears most often against it is Oshima Shipbuilding, with 337 hulls on record.

Alfred N was built in 1991, making it 35 years old. It is one of 1,166 hulls in this registry delivered that year, a cohort whose median tonnage is 2,997 GT; within it this ship is the 21st largest. 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.

The registry attributes 226 vessels to Fincantieri, with a median tonnage of 54,655 GT, delivered between 1935 and 2026. See the rest of that yard’s output.

At 325.0 m overall, Alfred N is 135.0 m longer than the 190.0 m median for bulk carriers on record, with a beam of 25.0 m and a draft of 10.0 m.

IMO numbers are issued in broadly chronological blocks. Within 500 either side of 8900438 this registry holds 46 other vessels, whose median build year is 1990 and which range from 1987 to 1994. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1991.

Its IMO number, 8900438, carries its own check digit. The first six digits are weighted seven down to two and summed — 8×7 + 9×6 + 0×5 + 0×4 + 4×3 + 3×2 = 128 — and the last digit of that total, 8, must equal the seventh digit, 8. It does, so this number is well formed.
