In brief
MV Carolyn Chouest is a chartered support ship for the United States Navy that was originally assigned to the Special Missions Program to support NR-1, the deep submergence craft. She towed NR-1 between work areas, served as a floating supply warehouse and provided quarters for extra crew until the NR-1 was removed from service in 2008.
Since the 2010s the ship has been used to support American special forces units in the Pacific region.

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 3,220 gross tons, Carolyn Chouest is the 50,760th 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 1.9 times smaller than the typical vessel on record here. The largest measures 499,167 GT.
Among the 1,423 offshore supplys held here, it ranks 392nd by tonnage — larger than 72% 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.
United States is the country of registry for 2,278 vessels in this directory, of which Carolyn Chouest is the 534th largest by tonnage. The most common class under that flag is vessels this registry holds no type classification for (977 ships), and the median vessel measures 1,706 GT. Browse every ship flagged United States.
Narrowing to both dimensions at once, this registry holds 283 offshore supplys flying the United States flag, of which 58 are larger by tonnage.
Carolyn Chouest was built in 1994, making it 32 years old. It is one of 1,047 hulls in this registry delivered that year, a cohort whose median tonnage is 5,680 GT; within it this ship is the 608th 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 95 vessels to North American Shipbuilding, with a median tonnage of 2,912 GT, delivered between 1978 and 2018. See the rest of that yard’s output.
At 69.5 m overall, Carolyn Chouest is 2.4 m longer than the 67.1 m median for offshore supplys on record, with a beam of 15.8 m and a draft of 17.0 m.
IMO numbers are issued in broadly chronological blocks. Within 500 either side of 8875384 this registry holds 30 other vessels, whose median build year is 1993 and which range from 1960 to 1994. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1994.
Its IMO number, 8875384, carries its own check digit. The first six digits are weighted seven down to two and summed — 8×7 + 8×6 + 7×5 + 5×4 + 3×3 + 8×2 = 184 — and the last digit of that total, 4, must equal the seventh digit, 4. It does, so this number is well formed.

Record
Events recorded against this vessel in the source, with the dates the source gives. An event with no date is listed last rather than assigned one.
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.
