Rokia Delmas

At 32,924 gross tons, Rokia Delmas is the 17,583rd 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 5.5 times the typical vessel on record here. The largest measures 499,167 GT.

Among the 3,881 container ships held here, it ranks 1,865th by tonnage — larger than 50% of that group. Their median tonnage is 33,698 GT, and the largest tenth begin at 140,096 GT. The flag most often flown by this group is Liberia (498 ships). The yard that appears most often against it is HD Hyundai Heavy Industries, with 348 hulls on record.

Rokia Delmas was built in 1985, making it 41 years old. It is one of 1,312 hulls in this registry delivered that year, a cohort whose median tonnage is 4,782 GT; within it this ship is the 127th 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 185.0 m overall, Rokia Delmas is 36.6 m shorter than the 221.6 m median for container ships on record.

IMO numbers are issued in broadly chronological blocks. Within 500 either side of 8315190 this registry holds 39 other vessels, whose median build year is 1984 and which range from 1983 to 1989. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1985.

Its IMO number, 8315190, carries its own check digit. The first six digits are weighted seven down to two and summed — 8×7 + 3×6 + 1×5 + 5×4 + 1×3 + 9×2 = 120 — and the last digit of that total, 0, must equal the seventh digit, 0. It does, so this number is well formed.
