Halvgrim was built in 1958, making it 68 years old. It is one of 267 hulls in this registry delivered that year, a cohort whose median tonnage is 718 GT; within it this ship is the 105th largest. 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.

IMO numbers are issued in broadly chronological blocks. Within 500 either side of 8968117 this registry holds 20 other vessels, whose median build year is 2001 and which range from 1958 to 2002. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1958.

Its IMO number, 8968117, carries its own check digit. The first six digits are weighted seven down to two and summed — 8×7 + 9×6 + 6×5 + 8×4 + 1×3 + 1×2 = 177 — and the last digit of that total, 7, must equal the seventh digit, 7. It does, so this number is well formed.
