Manchzhur

At 2,618 gross tons, Manchzhur is the 54,087th 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 2.3 times smaller than the typical vessel on record here. The largest measures 499,167 GT.

Among the 58,086 vessels this registry holds no type classification for held here, it ranks 30,719th by tonnage — larger than 38% of that group. Their median tonnage is 5,358 GT, and the largest tenth begin at 54,309 GT. The flag most often flown by this group is Panama (5,698 ships). The yard that appears most often against it is HD Hyundai Mipo, with 615 hulls on record.

Manchzhur was built in 1990, making it 36 years old. It is one of 1,306 hulls in this registry delivered that year, a cohort whose median tonnage is 2,025 GT; within it this ship is the 577th 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 63 vessels to Frederikshavn Shipyard, with a median tonnage of 9,784 GT, delivered between 1935 and 1999. See the rest of that yard’s output.

IMO numbers are issued in broadly chronological blocks. Within 500 either side of 8718184 this registry holds 44 other vessels, whose median build year is 1988 and which range from 1988 to 1990. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1990.

Its IMO number, 8718184, carries its own check digit. The first six digits are weighted seven down to two and summed — 8×7 + 7×6 + 1×5 + 8×4 + 1×3 + 8×2 = 154 — and the last digit of that total, 4, must equal the seventh digit, 4. It does, so this number is well formed.
