Grafitovyy

At 679 gross tons, Grafitovyy is the 70,404th 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 8.8 times smaller than the typical vessel on record here. The largest measures 499,167 GT.

Among the 58,086 vessels this registry holds no type classification for held here, it ranks 39,473rd by tonnage — larger than 21% of that group. Their median tonnage is 5,358 GT, and the largest tenth begin at 54,309 GT. The flag most often flown by this group is Panama (5,698 ships). The yard that appears most often against it is HD Hyundai Mipo, with 615 hulls on record.

Grafitovyy was built in 1978, making it 48 years old. It is one of 1,698 hulls in this registry delivered that year, a cohort whose median tonnage is 3,556 GT; within it this ship is the 1,161st largest. Across the whole of the 1970s the registry holds 17,331 vessels, median 2,774 GT. The median build year across the entire registry is 1995.

At 55.0 m overall, Grafitovyy is 60.0 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 7733448 this registry holds 25 other vessels, whose median build year is 1978 and which range from 1944 to 1978. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1978.

Its IMO number, 7733448, carries its own check digit. The first six digits are weighted seven down to two and summed — 7×7 + 7×6 + 3×5 + 3×4 + 4×3 + 4×2 = 138 — and the last digit of that total, 8, must equal the seventh digit, 8. It does, so this number is well formed.
