Orsk

Orsk was built in 1953, making it 73 years old. It is one of 179 hulls in this registry delivered that year, a cohort whose median tonnage is 3,502 GT. Across the whole of the 1950s the registry holds 2,005 vessels, median 960 GT. The median build year across the entire registry is 1995.

The registry attributes 55 vessels to Meyer Turku, with a median tonnage of 10,834 GT, delivered between 1951 and 2027. See the rest of that yard’s output.

At 69.0 m overall, Orsk is 46.0 m shorter 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 5265746 this registry holds 15 other vessels, whose median build year is 1956 and which range from 1909 to 1962. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1953.

Its IMO number, 5265746, carries its own check digit. The first six digits are weighted seven down to two and summed — 5×7 + 2×6 + 6×5 + 5×4 + 7×3 + 4×2 = 126 — and the last digit of that total, 6, must equal the seventh digit, 6. It does, so this number is well formed.
