Bigroll Barentsz was built in 2016, making it 10 years old. It is one of 1,628 hulls in this registry delivered that year, a cohort whose median tonnage is 26,388 GT; within it this ship is the 888th 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.

At 173.0 m overall, Bigroll Barentsz is 92.5 m longer than the 80.5 m median for heavy lifts on record, with a beam of 42.0 m.

IMO numbers are issued in broadly chronological blocks. Within 500 either side of 9710464 this registry holds 68 other vessels, whose median build year is 2015 and which range from 2013 to 2019. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 2016.

Its IMO number, 9710464, carries its own check digit. The first six digits are weighted seven down to two and summed — 9×7 + 7×6 + 1×5 + 0×4 + 4×3 + 6×2 = 134 — and the last digit of that total, 4, must equal the seventh digit, 4. It does, so this number is well formed.
