Heinrich S

At 25,624 gross tons, Heinrich S is the 22,628th 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 4.3 times the typical vessel on record here. The largest measures 499,167 GT.

Among the 3,881 container ships held here, it ranks 2,159th by tonnage — larger than 42% 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.

Heinrich S was built in 1998, making it 28 years old. It is one of 1,367 hulls in this registry delivered that year, a cohort whose median tonnage is 7,381 GT; within it this ship is the 345th 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 216 vessels to Volkswerft, with a median tonnage of 3,869 GT, delivered between 1955 and 2016. See the rest of that yard’s output.

At 207.4 m overall, Heinrich S is 14.2 m shorter than the 221.6 m median for container ships on record.

IMO numbers are issued in broadly chronological blocks. Within 500 either side of 9158513 this registry holds 65 other vessels, whose median build year is 1998 and which range from 1996 to 2005. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1998.

Its IMO number, 9158513, carries its own check digit. The first six digits are weighted seven down to two and summed — 9×7 + 1×6 + 5×5 + 8×4 + 5×3 + 1×2 = 143 — and the last digit of that total, 3, must equal the seventh digit, 3. It does, so this number is well formed.
