Helga

At 8,999 gross tons, Helga is the 37,414th 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 1.5 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 21,347th by tonnage — larger than 57% 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.

Helga was built in 2009, making it 17 years old. It is one of 2,834 hulls in this registry delivered that year, a cohort whose median tonnage is 11,673 GT; within it this ship is the 1,512th largest. Across the whole of the 2000s the registry holds 18,605 vessels, median 9,957 GT. The median build year across the entire registry is 1995.

The registry attributes 353 vessels to Damen Shipyards Gorinchem, with a median tonnage of 294 GT, delivered between 1972 and 2021. See the rest of that yard’s output.

At 142.9 m overall, Helga is 27.9 m longer than the 115.0 m median for vessels this registry holds no type classification for on record.

IMO numbers are issued in broadly chronological blocks. Within 500 either side of 9456719 this registry holds 60 other vessels, whose median build year is 2010 and which range from 2007 to 2014. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 2009.

Its IMO number, 9456719, carries its own check digit. The first six digits are weighted seven down to two and summed — 9×7 + 4×6 + 5×5 + 6×4 + 7×3 + 1×2 = 159 — and the last digit of that total, 9, must equal the seventh digit, 9. It does, so this number is well formed.
