Seaturbot

At 21,353 gross tons, Seaturbot is the 25,738th 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 3.6 times the typical vessel on record here. The largest measures 499,167 GT.

Among the 3,060 oil tankers held here, it ranks 1,504th by tonnage — larger than 49% of that group. Their median tonnage is 22,184 GT, and the largest tenth begin at 149,274 GT. The flag most often flown by this group is Panama (301 ships). The yard that appears most often against it is HD Hyundai Mipo, with 190 hulls on record.

Seaturbot was built in 2000, making it 26 years old. It is one of 1,296 hulls in this registry delivered that year, a cohort whose median tonnage is 8,737 GT; within it this ship is the 440th 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.

The registry attributes 76 vessels to Lindenau Shipyard, with a median tonnage of 7,894 GT, delivered between 1956 and 2011. See the rest of that yard’s output.

At 177.7 m overall, Seaturbot is 1.3 m shorter than the 179.0 m median for oil tankers on record and a draft of 11.0 m.

IMO numbers are issued in broadly chronological blocks. Within 500 either side of 9204764 this registry holds 53 other vessels, whose median build year is 2000 and which range from 1993 to 2003. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 2000.

Its IMO number, 9204764, carries its own check digit. The first six digits are weighted seven down to two and summed — 9×7 + 2×6 + 0×5 + 4×4 + 7×3 + 6×2 = 124 — and the last digit of that total, 4, must equal the seventh digit, 4. It does, so this number is well formed.
