Ternvag

At 9,993 gross tons, Ternvag is the 35,702nd 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 1.7 times the typical vessel on record here. The largest measures 499,167 GT.

Among the 2,402 tankers held here, it ranks 1,064th by tonnage — larger than 53% of that group. Their median tonnage is 8,256 GT, and the largest tenth begin at 42,340 GT. The flag most often flown by this group is Panama (219 ships). The yard that appears most often against it is HD Hyundai Mipo, with 175 hulls on record.

Ternvag was built in 2003, making it 23 years old. It is one of 1,383 hulls in this registry delivered that year, a cohort whose median tonnage is 11,954 GT; within it this ship is the 691st 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 141.2 m overall, Ternvag is 2.2 m longer than the 139.0 m median for tankers on record, with a beam of 21.9 m and a draft of 9.0 m.

IMO numbers are issued in broadly chronological blocks. Within 500 either side of 9277371 this registry holds 69 other vessels, whose median build year is 2003 and which range from 2002 to 2009. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 2003.

Its IMO number, 9277371, carries its own check digit. The first six digits are weighted seven down to two and summed — 9×7 + 2×6 + 7×5 + 7×4 + 3×3 + 7×2 = 161 — and the last digit of that total, 1, must equal the seventh digit, 1. It does, so this number is well formed.
