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 149,282 gross tons, Ruby IV is the 1,502nd 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 25 times the typical vessel on record here. The largest measures 499,167 GT.
Among the 3,060 oil tankers held here, it ranks 293rd by tonnage — larger than 90% of that group. Their median tonnage is 22,184 GT, and the largest tenth begin at 149,274 GT. The flag most often flown by this group is Panama (301 ships). The yard that appears most often against it is HD Hyundai Mipo, with 190 hulls on record.
Comoros is the country of registry for 506 vessels in this directory, of which Ruby IV is the 9th largest by tonnage. The most common class under that flag is vessels this registry holds no type classification for (295 ships), and the median vessel measures 8,205 GT. Browse every ship flagged Comoros.
Narrowing to both dimensions at once, this registry holds 46 oil tankers flying the Comoros flag, of which 5 are larger by tonnage.
Ruby IV was built in 2000, making it 26 years old. It is one of 1,296 hulls in this registry delivered that year, a cohort whose median tonnage is 8,737 GT; within it this ship is the 33rd 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 240 vessels to IHI Marine United, with a median tonnage of 52,902 GT, delivered between 1963 and 2013. See the rest of that yard’s output.
At 330.0 m overall, Ruby IV is 151.0 m longer than the 179.0 m median for oil tankers on record.
IMO numbers are issued in broadly chronological blocks. Within 500 either side of 9197856 this registry holds 78 other vessels, whose median build year is 2000 and which range from 1998 to 2005. That places this hull’s registration in the same part of the series.

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.

Measurements
Its IMO number, 9197856, carries its own check digit. The first six digits are weighted seven down to two and summed — 9×7 + 1×6 + 9×5 + 7×4 + 8×3 + 5×2 = 176 — and the last digit of that total, 6, must equal the seventh digit, 6. It does, so this number is well formed.
