About Pioneering Spirit
Pioneering Spirit, formerly Pieter Schelte, is a split hull crane vessel owned by Allseas designed for the single-lift installation and removal of large oil and gas platforms, and pipelines. The 382-metre-long (1,253 ft), 124-metre-wide (407 ft) vessel is the world's largest vessel by gross tonnage, the heaviest vehicle ever made and since September 2021 also the largest floating sheerleg in the world. It was built in South Korea by Daewoo Shipbuilding & Marine Engineering in 2013 at a cost of €2.6 billion. It commenced offshore operations in August 2016.

In context
How Pioneering Spirit compares
Every figure in this section is a count, a rank or a percentile over vessels actually held in this registry — not over the world fleet, which is larger. Nothing here is estimated.
At 403,342 gross tons, Pioneering Spirit is the 2nd 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 67 times the typical vessel on record here. The largest measures 499,167 GT.
Among the 255 heavy lifts held here, it ranks 1st by tonnage — larger than 100% of that group. Their median tonnage is 1,670 GT, and the largest tenth begin at 24,484 GT. The flag most often flown by this group is Russia (41 ships). The yard that appears most often against it is Pella Sietas, with 8 hulls on record.
Malta is the country of registry for 2,640 vessels in this directory, of which Pioneering Spirit is the 1st largest by tonnage. The most common class under that flag is vessels this registry holds no type classification for (1,614 ships), and the median vessel measures 23,204 GT. Browse every ship flagged Malta.
Narrowing to both dimensions at once, this registry holds 4 heavy lifts flying the Malta flag, of which none is larger than Pioneering Spirit.
Pioneering Spirit was built in 2014, making it 12 years old. It is one of 1,868 hulls in this registry delivered that year, a cohort whose median tonnage is 21,828 GT; within it this ship is the 1st 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.
The registry attributes 1,090 vessels to Hanwha Ocean, with a median tonnage of 84,214 GT, delivered between 1982 and 2025. See the rest of that yard’s output.
At 382.0 m overall, Pioneering Spirit is 301.5 m longer than the 80.5 m median for heavy lifts on record, with a beam of 124.0 m and a draft of 27.0 m.
IMO numbers are issued in broadly chronological blocks. Within 500 either side of 9593505 this registry holds 72 other vessels, whose median build year is 2012 and which range from 2010 to 2015. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 2014.
Its IMO number, 9593505, carries its own check digit. The first six digits are weighted seven down to two and summed — 9×7 + 5×6 + 9×5 + 3×4 + 5×3 + 0×2 = 165 — and the last digit of that total, 5, must equal the seventh digit, 5. It does, so this number is well formed.
