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.[1][2] Previously known as Olympic Athene and originally Olympic Boa, the ship was launched in 2013 and is flagged in Norway.[3] 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).[4]

Seabed Constructor participated in the search for Malaysia Airlines Flight 370.[5][6] It was operated by Ocean Infinity on a 90-day search contract for the missing aircraft; the mission ended unsuccessfully in mid-June 2018.[7]

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.[8]

On 22 July 2019, the French government announced that drones launched from Seabed Constructor had found the French submarine Minerve, lost at sea in 1968.[9]

On 4 December 2019, search teams from Seabed Constructor located the wreckage of SMS Scharnhorst, the flagship of the German Empire's East Asia Squadron during World War I, at a depth of 1,610 m (5,280 ft), some 98 nmi (181 km; 113 mi) southeast of the Falkland Islands.[10]
