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 157,833 gross tons, Impalas is the 994th 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 26 times the typical vessel on record here. The largest measures 499,167 GT.
Among the 3,060 oil tankers held here, it ranks 202nd by tonnage — larger than 93% 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.
Panama is the country of registry for 9,598 vessels in this directory, of which Impalas is the 151st largest by tonnage. The most common class under that flag is vessels this registry holds no type classification for (5,698 ships), and the median vessel measures 18,203 GT. Browse every ship flagged Panama.
Narrowing to both dimensions at once, this registry holds 301 oil tankers flying the Panama flag, of which 44 are larger by tonnage.
Impalas was built in 1999, making it 27 years old. It is one of 1,252 hulls in this registry delivered that year, a cohort whose median tonnage is 8,594 GT; within it this ship is the 18th 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 1,090 vessels to Hanwha Ocean, with a median tonnage of 84,214 GT, delivered between 1982 and 2025. See the rest of that yard’s output.
At 332.0 m overall, Impalas is 153.0 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 9171448 this registry holds 60 other vessels, whose median build year is 1999 and which range from 1997 to 2002. 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, 9171448, carries its own check digit. The first six digits are weighted seven down to two and summed — 9×7 + 1×6 + 7×5 + 1×4 + 4×3 + 4×2 = 128 — and the last digit of that total, 8, must equal the seventh digit, 8. It does, so this number is well formed.
