In brief
Seabed Constructor is a multipurpose offshore vessel owned by Swire Seabed and contracted since December 2016 to British-owned hydrographic survey company Ocean Infinity, based in Houston, Texas, United States. Previously known as Olympic Athene and originally Olympic Boa, the ship was launched in 2013 and is flagged in Norway. The ship is designed to conduct geophysical and geotechnical surveys of the seabed, support the construction or demolition of underwater structures, conduct trenching and excavation operations, and serve as a ROV platform for the company's autonomous underwater vehicles and unmanned surface vehicles. The ship is 114 metres (374 ft) in length, with a 22 metres (72 ft) beam, a gross tonnage of 7,883, and deadweight tonnage of 6,480 metric tons. Its maximum speed is 14.1 knots (26.1 km/h; 16.2 mph).
Seabed Constructor participated in the search for Malaysia Airlines Flight 370. It was operated by Ocean Infinity on a 90-day search contract for the missing aircraft; the mission ended unsuccessfully in mid-June 2018.
Seabed Constructor was then contracted by the Argentine Navy to search for the missing submarine ARA San Juan. On 17 November 2018, Seabed Constructor found San Juan a year and two days after the submarine's disappearance. The submarine lies on the seabed at a depth of 920 metres (3,020 ft) below sea level.

In context
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 7,883 gross tons, Orient Constructor is the 38,869th 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 1.3 times the typical vessel on record here. The largest measures 499,167 GT.
Among the 58,086 vessels this registry holds no type classification for held here, it ranks 22,236th by tonnage — larger than 55% of that group. Their median tonnage is 5,358 GT, and the largest tenth begin at 54,309 GT. The flag most often flown by this group is Panama (5,698 ships). The yard that appears most often against it is HD Hyundai Mipo, with 615 hulls on record.
Norway is the country of registry for 3,032 vessels in this directory, of which Orient Constructor is the 783rd largest by tonnage. The most common class under that flag is vessels this registry holds no type classification for (2,126 ships), and the median vessel measures 3,102 GT. Browse every ship flagged Norway.
Narrowing to both dimensions at once, this registry holds 2,126 vessels this registry holds no type classification for flying the Norway flag, of which 562 are larger by tonnage.
Orient Constructor 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 1,086th 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 103 vessels to Kleven Verft, with a median tonnage of 5,388 GT, delivered between 1963 and 2019. See the rest of that yard’s output.
At 115.4 m overall, Orient Constructor is within a metre of the 115.0 m median length for vessels this registry holds no type classification for on record, with a beam of 22.0 m and a draft of 7.1 m.
IMO numbers are issued in broadly chronological blocks. Within 500 either side of 9682148 this registry holds 62 other vessels, whose median build year is 2014 and which range from 2010 to 2016. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 2014.
Its IMO number, 9682148, carries its own check digit. The first six digits are weighted seven down to two and summed — 9×7 + 6×6 + 8×5 + 2×4 + 1×3 + 4×2 = 158 — and the last digit of that total, 8, must equal the seventh digit, 8. It does, so this number is well formed.
