Firmeza

At 36,152 gross tons, Firmeza is the 15,632nd 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 6.0 times 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 8,615th by tonnage — larger than 83% 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.

Firmeza was built in 1986, making it 40 years old. It is one of 866 hulls in this registry delivered that year, a cohort whose median tonnage is 4,769 GT; within it this ship is the 106th largest. 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 181 vessels to NKK, with a median tonnage of 56,076 GT, delivered between 1958 and 2003. See the rest of that yard’s output.

At 194.9 m overall, Firmeza is 79.9 m longer than the 115.0 m median for vessels this registry holds no type classification for on record and a draft of 10.5 m.

IMO numbers are issued in broadly chronological blocks. Within 500 either side of 8519370 this registry holds 14 other vessels, whose median build year is 1986 and which range from 1985 to 1989. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1986.

Its IMO number, 8519370, carries its own check digit. The first six digits are weighted seven down to two and summed — 8×7 + 5×6 + 1×5 + 9×4 + 3×3 + 7×2 = 150 — and the last digit of that total, 0, must equal the seventh digit, 0. It does, so this number is well formed.
