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 212 gross tons, «Wulf 4» is the 80,513th 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 28 times smaller than the typical vessel on record here. The largest measures 499,167 GT.
Among the 1,471 tugs held here, it ranks 990th by tonnage — larger than 22% of that group. Their median tonnage is 393 GT, and the largest tenth begin at 1,733 GT. The flag most often flown by this group is United States (239 ships). The yard that appears most often against it is Damen Shipyards Gorinchem, with 62 hulls on record.
Germany is the country of registry for 885 vessels in this directory, of which «Wulf 4» is the 597th largest by tonnage. The most common class under that flag is vessels this registry holds no type classification for (446 ships), and the median vessel measures 916 GT. Browse every ship flagged Germany.
Narrowing to both dimensions at once, this registry holds 70 tugs flying the Germany flag, of which 62 are larger by tonnage.
«Wulf 4» was built in 2011, making it 15 years old. It is one of 2,848 hulls in this registry delivered that year, a cohort whose median tonnage is 23,456 GT; within it this ship is the 2,713th largest. Across the whole of the 2010s the registry holds 20,111 vessels, median 23,456 GT. The median build year across the entire registry is 1995.
The registry attributes 76 vessels to Damen Shipyards Hardinxveld, with a median tonnage of 309 GT, delivered between 1975 and 2024. See the rest of that yard’s output.
At 26.0 m overall, «Wulf 4» is 6.3 m shorter than the 32.3 m median for tugs on record, with a beam of 9.1 m and a draft of 2.6 m.
IMO numbers are issued in broadly chronological blocks. Within 500 either side of 9639737 this registry holds 65 other vessels, whose median build year is 2013 and which range from 2011 to 2020. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 2011.
Its IMO number, 9639737, carries its own check digit. The first six digits are weighted seven down to two and summed — 9×7 + 6×6 + 3×5 + 9×4 + 7×3 + 3×2 = 177 — and the last digit of that total, 7, must equal the seventh digit, 7. It does, so this number is well formed.
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.
