At 190,000 gross tons, Thunder Horse PDQ is the 253rd 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 32 times the typical vessel on record here. The largest measures 499,167 GT.

Across the whole of the 2000s the registry holds 18,605 vessels, median 9,957 GT. The median build year across the entire registry is 1995.

IMO numbers are issued in broadly chronological blocks. Within 500 either side of 8765199 this registry holds 52 other vessels, whose median build year is 2002 and which range from 1972 to 2009. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 2007.

Its IMO number, 8765199, carries its own check digit. The first six digits are weighted seven down to two and summed — 8×7 + 7×6 + 6×5 + 5×4 + 1×3 + 9×2 = 169 — and the last digit of that total, 9, must equal the seventh digit, 9. It does, so this number is well formed.
