How Blue Dolphin compares

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 4,769 gross tons, Blue Dolphin is the 45,200th 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 1.3 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 149th by tonnage — larger than 89% 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 Blue Dolphin is the 428th 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 9 are larger by tonnage.

Blue Dolphin was built in 2009, making it 17 years old. It is one of 2,834 hulls in this registry delivered that year, a cohort whose median tonnage is 11,673 GT; within it this ship is the 1,822nd largest. Across the whole of the 2000s the registry holds 18,605 vessels, median 9,957 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 91.6 m overall, Blue Dolphin is 24.5 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 9529724 this registry holds 63 other vessels, whose median build year is 2011 and which range from 2008 to 2014. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 2009.

Its IMO number, 9529724, carries its own check digit. The first six digits are weighted seven down to two and summed — 9×7 + 5×6 + 2×5 + 9×4 + 7×3 + 2×2 = 164 — and the last digit of that total, 4, must equal the seventh digit, 4. It does, so this number is well formed.
