Sleipnir

Sleipnir was built in 2019, making it 7 years old. It is one of 1,261 hulls in this registry delivered that year, a cohort whose median tonnage is 29,000 GT. 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 12 vessels to Seatrium Limited, with a median tonnage of 29,631 GT, delivered between 1997 and 2024. See the rest of that yard’s output.

At 220.0 m overall, Sleipnir is 139.5 m longer than the 80.5 m median for heavy lifts on record, with a beam of 102.0 m and a draft of 32.0 m.

IMO numbers are issued in broadly chronological blocks. Within 500 either side of 9781425 this registry holds 46 other vessels, whose median build year is 2018 and which range from 2016 to 2021. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 2019.

Its IMO number, 9781425, carries its own check digit. The first six digits are weighted seven down to two and summed — 9×7 + 7×6 + 8×5 + 1×4 + 4×3 + 2×2 = 165 — and the last digit of that total, 5, must equal the seventh digit, 5. It does, so this number is well formed.
