IMO 8758847

IMO 8758847 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 65 vessels to Götaverken, with a median tonnage of 7,041 GT, delivered between 1910 and 1989. See the rest of that yard’s output.

At 124.0 m overall, IMO 8758847 is 50.0 m longer than the 74.0 m median for rig / offshore units on record.

IMO numbers are issued in broadly chronological blocks. Within 500 either side of 8758847 this registry holds 32 other vessels, whose median build year is 1977 and which range from 1929 to 1984. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1981.

Its IMO number, 8758847, carries its own check digit. The first six digits are weighted seven down to two and summed — 8×7 + 7×6 + 5×5 + 8×4 + 8×3 + 4×2 = 187 — and the last digit of that total, 7, must equal the seventh digit, 7. It does, so this number is well formed.
