DG Harmony

At 18,000 gross tons, DG Harmony is the 28,053rd 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 3.0 times 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 15,690th by tonnage — larger than 68% 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.

DG Harmony 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 220th 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 129 vessels to Bremer Vulkan, with a median tonnage of 18,037 GT, delivered between 1909 and 2000. See the rest of that yard’s output.

IMO numbers are issued in broadly chronological blocks. Within 500 either side of 8900218 this registry holds 39 other vessels, whose median build year is 1991 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 1990.

Its IMO number, 8900218, 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 + 2×3 + 1×2 = 118 — and the last digit of that total, 8, must equal the seventh digit, 8. It does, so this number is well formed.
