Bonn Express

At 35,919 gross tons, Bonn Express is the 15,767th 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 6.0 times the typical vessel on record here. The largest measures 499,167 GT.

Among the 3,881 container ships held here, it ranks 1,787th by tonnage — larger than 52% of that group. Their median tonnage is 33,698 GT, and the largest tenth begin at 140,096 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.

Bonn Express was built in 1989, making it 37 years old. It is one of 1,131 hulls in this registry delivered that year, a cohort whose median tonnage is 1,938 GT; within it this ship is the 118th largest. Across the whole of the 1980s the registry holds 13,213 vessels, median 3,004 GT. The median build year across the entire registry is 1995.

The registry attributes 210 vessels to Howaldtswerke-Deutsche Werft, with a median tonnage of 30,285 GT, delivered between 1905 and 2010. See the rest of that yard’s output.

At 235.0 m overall, Bonn Express is 13.4 m longer than the 221.6 m median for container ships on record.

IMO numbers are issued in broadly chronological blocks. Within 500 either side of 8711368 this registry holds 50 other vessels, whose median build year is 1989 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 1989.

Its IMO number, 8711368, carries its own check digit. The first six digits are weighted seven down to two and summed — 8×7 + 7×6 + 1×5 + 1×4 + 3×3 + 6×2 = 128 — and the last digit of that total, 8, must equal the seventh digit, 8. It does, so this number is well formed.
