Happy Delta 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 1,690th 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.

IMO numbers are issued in broadly chronological blocks. Within 500 either side of 9551935 this registry holds 65 other vessels, whose median build year is 2011 and which range from 2008 to 2017. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 2011.

Its IMO number, 9551935, carries its own check digit. The first six digits are weighted seven down to two and summed — 9×7 + 5×6 + 5×5 + 1×4 + 9×3 + 3×2 = 155 — and the last digit of that total, 5, must equal the seventh digit, 5. It does, so this number is well formed.
