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 156,692 gross tons, Dai Sy is the 1,108th 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 244th by tonnage — larger than 92% 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.
Palau is the country of registry for 364 vessels in this directory, of which Dai Sy is the 7th largest by tonnage. The most common class under that flag is vessels this registry holds no type classification for (144 ships), and the median vessel measures 8,686 GT. Browse every ship flagged Palau.
Narrowing to both dimensions at once, this registry holds 64 oil tankers flying the Palau flag, of which 4 are larger by tonnage.
Dai Sy was built in 1998, making it 28 years old. It is one of 1,367 hulls in this registry delivered that year, a cohort whose median tonnage is 7,381 GT; within it this ship is the 6th 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 1,480 vessels to HD Hyundai Mipo, with a median tonnage of 29,375 GT, delivered between 1979 and 2025. See the rest of that yard’s output.
At 330.0 m overall, Dai Sy 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 9158898 this registry holds 73 other vessels, whose median build year is 1997 and which range from 1996 to 2000. That places this hull’s registration in the same part of the series.
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.

Measurements
Its IMO number, 9158898, carries its own check digit. The first six digits are weighted seven down to two and summed — 9×7 + 1×6 + 5×5 + 8×4 + 8×3 + 9×2 = 168 — and the last digit of that total, 8, must equal the seventh digit, 8. It does, so this number is well formed.
