At 17,496 gross tons, Seven Atlantic is the 28,524th 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 2.9 times the typical vessel on record here. The largest measures 499,167 GT.
Among the 1,423 offshore supplys held here, it ranks 26th by tonnage — larger than 98% of that group. Their median tonnage is 2,061 GT, and the largest tenth begin at 4,961 GT. The flag most often flown by this group is United States (283 ships). The yard that appears most often against it is North American Shipbuilding, with 55 hulls on record.
Seven Atlantic was built in 2010, making it 16 years old. It is one of 3,028 hulls in this registry delivered that year, a cohort whose median tonnage is 20,204 GT; within it this ship is the 1,561st largest. Across the whole of the 2010s the registry holds 20,111 vessels, median 23,456 GT. The median build year across the entire registry is 1995.
The registry attributes 85 vessels to Royal IHC, with a median tonnage of 9,125 GT, delivered between 1947 and 2024. See the rest of that yard’s output.
At 144.8 m overall, Seven Atlantic is 77.7 m longer than the 67.1 m median for offshore supplys on record.
IMO numbers are issued in broadly chronological blocks. Within 500 either side of 9419125 this registry holds 80 other vessels, whose median build year is 2009 and which range from 2006 to 2013. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 2010.
Its IMO number, 9419125, carries its own check digit. The first six digits are weighted seven down to two and summed — 9×7 + 4×6 + 1×5 + 9×4 + 1×3 + 2×2 = 135 — and the last digit of that total, 5, must equal the seventh digit, 5. It does, so this number is well formed.
