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 7,320 gross tons, Atlantic Challenger is the 39,737th 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 1.2 times the typical vessel on record here. The largest measures 499,167 GT.
Among the 1,423 offshore supplys held here, it ranks 78th by tonnage — larger than 94% 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.
Mexico is the country of registry for 471 vessels in this directory, of which Atlantic Challenger is the 58th largest by tonnage. The most common class under that flag is vessels this registry holds no type classification for (370 ships), and the median vessel measures 1,019 GT. Browse every ship flagged Mexico.
Narrowing to both dimensions at once, this registry holds 41 offshore supplys flying the Mexico flag, of which none is larger than Atlantic Challenger.
Atlantic Challenger was built in 1990, making it 36 years old. It is one of 1,306 hulls in this registry delivered that year, a cohort whose median tonnage is 2,025 GT; within it this ship is the 334th 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 216 vessels to Volkswerft, with a median tonnage of 3,869 GT, delivered between 1955 and 2016. See the rest of that yard’s output.
At 120.0 m overall, Atlantic Challenger 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 8607311 this registry holds 23 other vessels. That places this hull’s registration in the same part of the series.
Same yard, same years
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.

Measurements
Its IMO number, 8607311, carries its own check digit. The first six digits are weighted seven down to two and summed — 8×7 + 6×6 + 0×5 + 7×4 + 3×3 + 1×2 = 131 — and the last digit of that total, 1, must equal the seventh digit, 1. It does, so this number is well formed.
