ONE Olympus

At 98,799 gross tons, ONE Olympus is the 3,366th 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 16 times the typical vessel on record here. The largest measures 499,167 GT.

Among the 3,881 container ships held here, it ranks 553rd by tonnage — larger than 85% of that group. Their median tonnage is 33,698 GT, and the largest tenth begin at 140,096 GT. The flag most often flown by this group is Liberia (498 ships). The yard that appears most often against it is HD Hyundai Heavy Industries, with 348 hulls on record.

ONE Olympus was built in 2008, making it 18 years old. It is one of 2,764 hulls in this registry delivered that year, a cohort whose median tonnage is 8,971 GT; within it this ship is the 115th largest. 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.

The registry attributes 240 vessels to IHI Marine United, with a median tonnage of 52,902 GT, delivered between 1963 and 2013. See the rest of that yard’s output.

At 336.0 m overall, ONE Olympus is 114.4 m longer than the 221.6 m median for container ships on record and a draft of 14.1 m.

IMO numbers are issued in broadly chronological blocks. Within 500 either side of 9312987 this registry holds 79 other vessels, whose median build year is 2006 and which range from 2004 to 2011. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 2008.

Its IMO number, 9312987, carries its own check digit. The first six digits are weighted seven down to two and summed — 9×7 + 3×6 + 1×5 + 2×4 + 9×3 + 8×2 = 137 — and the last digit of that total, 7, must equal the seventh digit, 7. It does, so this number is well formed.
