Proliv Nadezhdy

Proliv Nadezhdy was built in 1981, making it 45 years old. It is one of 1,653 hulls in this registry delivered that year, a cohort whose median tonnage is 3,186 GT. 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 74 vessels to Mykolayiv Shipyard, with a median tonnage of 844 GT, delivered between 1958 and 2008. See the rest of that yard’s output.

At 172.1 m overall, Proliv Nadezhdy is 57.1 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 7941887 this registry holds 38 other vessels, whose median build year is 1981 and which range from 1945 to 1981. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1981.

Its IMO number, 7941887, carries its own check digit. The first six digits are weighted seven down to two and summed — 7×7 + 9×6 + 4×5 + 1×4 + 8×3 + 8×2 = 167 — and the last digit of that total, 7, must equal the seventh digit, 7. It does, so this number is well formed.
