Vox Ariane

At 11,910 gross tons, Vox Ariane is the 33,570th 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 2.0 times the typical vessel on record here. The largest measures 499,167 GT.

Among the 360 dredgers held here, it ranks 33rd by tonnage — larger than 90% of that group. Their median tonnage is 2,086 GT, and the largest tenth begin at 11,701 GT. The flag most often flown by this group is People's Republic of China (43 ships). The yard that appears most often against it is Royal IHC, with 21 hulls on record.

Vox Ariane was built in 2022, making it 4 years old. It is one of 158 hulls in this registry delivered that year, a cohort whose median tonnage is 25,795 GT; within it this ship is the 63rd largest. Across the whole of the 2020s the registry holds 1,769 vessels, median 29,777 GT. The median build year across the entire registry is 1995.

The registry attributes 4 vessels to Keppel Singmarine, with a median tonnage of 11,910 GT, delivered between 2005 and 2023. See the rest of that yard’s output.

At 137.5 m overall, Vox Ariane is 57.5 m longer than the 80.0 m median for dredgers on record.

IMO numbers are issued in broadly chronological blocks. Within 500 either side of 9867085 this registry holds 41 other vessels, whose median build year is 2020 and which range from 2017 to 2022. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 2022.

Its IMO number, 9867085, carries its own check digit. The first six digits are weighted seven down to two and summed — 9×7 + 8×6 + 6×5 + 7×4 + 0×3 + 8×2 = 185 — and the last digit of that total, 5, must equal the seventh digit, 5. It does, so this number is well formed.
