In context
Every figure in this section is a count, a rank or a percentile over vessels actually held in this registry — not over the world fleet, which is larger. Nothing here is estimated.
At 11,071 gross tons, Seven Falcon is the 34,550th 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 1.8 times the typical vessel on record here. The largest measures 499,167 GT.
Among the 1,423 offshore supplys held here, it ranks 53rd by tonnage — larger than 96% 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.
Isle of Man is the country of registry for 211 vessels in this directory, of which Seven Falcon is the 121st largest by tonnage. The most common class under that flag is vessels this registry holds no type classification for (152 ships), and the median vessel measures 18,311 GT. Browse every ship flagged Isle of Man.
Narrowing to both dimensions at once, this registry holds 7 offshore supplys flying the Isle of Man flag, of which 3 are larger by tonnage.
Seven Falcon was built in 2011, making it 15 years old. It is one of 2,848 hulls in this registry delivered that year, a cohort whose median tonnage is 23,456 GT; within it this ship is the 1,783rd 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 76 vessels to Havyard Ship Technology, with a median tonnage of 2,807 GT, delivered between 1957 and 2021. See the rest of that yard’s output.
At 120.0 m overall, Seven Falcon is 52.9 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 9455167 this registry holds 36 other vessels, whose median build year is 2010 and which range from 2008 to 2015. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 2011.
Its IMO number, 9455167, carries its own check digit. The first six digits are weighted seven down to two and summed — 9×7 + 4×6 + 5×5 + 5×4 + 1×3 + 6×2 = 147 — and the last digit of that total, 7, must equal the seventh digit, 7. It does, so this number is well formed.

No ship class is recorded for this vessel, so these are not asserted to be sister ships — they are contemporaries from the same builder, shown because that is what the data supports.
