Thasos

At 25,499 gross tons, Thasos is the 22,738th 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 4.3 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 12,707th by tonnage — larger than 74% 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.

Thasos was built in 1998, making it 28 years old. It is one of 1,367 hulls in this registry delivered that year, a cohort whose median tonnage is 7,381 GT; within it this ship is the 351st largest. Across the whole of the 1990s the registry holds 12,006 vessels, median 4,956 GT. The median build year across the entire registry is 1995.

The registry attributes 111 vessels to Nordseewerke, with a median tonnage of 21,699 GT, delivered between 1916 and 2010. See the rest of that yard’s output.

At 199.9 m overall, Thasos is 84.9 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 9166651 this registry holds 62 other vessels, whose median build year is 1998 and which range from 1997 to 2001. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1998.

Its IMO number, 9166651, carries its own check digit. The first six digits are weighted seven down to two and summed — 9×7 + 1×6 + 6×5 + 6×4 + 6×3 + 5×2 = 151 — and the last digit of that total, 1, must equal the seventh digit, 1. It does, so this number is well formed.
