Luminous Sky

At 45,011 gross tons, Luminous Sky is the 10,976th 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 7.5 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 6,021st by tonnage — larger than 88% 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.

Luminous Sky was built in 2005, making it 21 years old. It is one of 1,690 hulls in this registry delivered that year, a cohort whose median tonnage is 12,046 GT; within it this ship is the 302nd largest. Across the whole of the 2000s the registry holds 18,605 vessels, median 9,957 GT. The median build year across the entire registry is 1995.

At 203.5 m overall, Luminous Sky is 88.5 m longer 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 9303118 this registry holds 80 other vessels, whose median build year is 2005 and which range from 2003 to 2007. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 2005.

Its IMO number, 9303118, carries its own check digit. The first six digits are weighted seven down to two and summed — 9×7 + 3×6 + 0×5 + 3×4 + 1×3 + 1×2 = 98 — and the last digit of that total, 8, must equal the seventh digit, 8. It does, so this number is well formed.
