In brief
USNS Titan (T-AGOS-15) was a Stalwart-class modified tactical auxiliary general ocean surveillance ship in service in the United States Navy from 1989 to 1993. From 1996 to 2014, she was in commission in the National Oceanic and Atmospheric Administration (NOAA) fleet as the oceanographic research ship NOAAS Ka'imimoana (R 333).

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 2,014 gross tons, Ocean Titan is the 57,673rd 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 3.0 times smaller than the typical vessel on record here. The largest measures 499,167 GT.
Among the 612 research / surveys held here, it ranks 256th by tonnage — larger than 47% of that group. Their median tonnage is 2,180 GT, and the largest tenth begin at 9,452 GT. The flag most often flown by this group is United States (90 ships). The yard that appears most often against it is Wärtsilä, with 36 hulls on record.
United States is the country of registry for 2,278 vessels in this directory, of which Ocean Titan is the 712th 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 90 research / surveys flying the United States flag, of which 35 are larger by tonnage.
The registry attributes 40 vessels to Bollinger Mississippi Shipbuilding, with a median tonnage of 2,218 GT, delivered between 1972 and 2018. See the rest of that yard’s output.
At 68.3 m overall, Ocean Titan is 2.7 m shorter than the 71.0 m median for research / surveys on record, with a beam of 13.1 m and a draft of 4.6 m.
IMO numbers are issued in broadly chronological blocks. Within 500 either side of 8835231 this registry holds 52 other vessels, whose median build year is 1984 and which range from 1944 to 1990. That places this hull’s registration in the same part of the series; no build year is recorded for this vessel itself.
Its IMO number, 8835231, carries its own check digit. The first six digits are weighted seven down to two and summed — 8×7 + 8×6 + 3×5 + 5×4 + 2×3 + 3×2 = 151 — and the last digit of that total, 1, must equal the seventh digit, 1. It does, so this number is well formed.
