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]

Ownership and operational history

Early ownership and naming

The Seabed Constructor was originally delivered in April 2014 to Olympic Shipping, a Norwegian offshore support vessel operator based in Fosnavåg, as the Olympic Boa, a multipurpose subsea support and construction vessel designed by Marin Teknikk.https://www.ship-technology.com/projects/mv-olympic-boa-subsea-support-and-construction-vessel/ The vessel was built by Kleven Verft in , , and immediately entered service under the Norwegian flag for general subsea construction, inspection, maintenance, and repair (IMR) tasks, as well as survey operations in the and other offshore regions.https://www.offshore-energy.biz/olympic-boa-marine-in-dispute-over-olympic-boa/ Upon delivery, Olympic Shipping chartered the vessel to Boa Marine Services for a three-year period plus options, during which it was briefly renamed Olympic Athene to reflect the arrangement.https://www.offshore-energy.biz/boa-marine-charters-olympic-boa-ocv/ The Olympic Athene continued its role in subsea operations, supporting tasks such as pipeline installation, ROV deployments, and seabed surveys, leveraging its helideck, system, and crane capabilities.https://www.offshore-energy.biz/olympic-boa-marine-in-dispute-over-olympic-boa/ In December 2016, Olympic Shipping sold the vessel to Pacific Offshore's subsea division, which was rebranded as Swire Seabed, for an undisclosed sum.https://www.tradewindsnews.com/ship-sales/olympic-ship-sells-vessel-to-swire-pacific/1-1-1196944 Following the acquisition, the vessel was renamed Seabed Constructor in preparation for specialized survey charters, marking the transition to its next phase of operations while retaining its Norwegian registry.https://splash247.com/swire-pacific-offshore-takes-olympic-vessel/

Charter to Ocean Infinity

In December 2016, Swire Seabed entered into a six-year charter agreement with Ocean Infinity, a UK-based marine technology company specializing in hydrographic surveys and seabed exploration. Under the terms of the deal, the vessel—previously known as Olympic Athene—was renamed Seabed Constructor and equipped for advanced subsea operations, including the deployment of autonomous underwater vehicles (AUVs) and remotely operated vehicles (ROVs). This partnership enabled Ocean Infinity to leverage the ship's capabilities for large-scale seabed mapping and data collection missions worldwide. In late 2019, Swire Pacific Offshore closed its Norwegian-based Swire Seabed AS subsidiary, integrating the vessel into its Singapore operations, after which it was renamed Pacific Constructor in early 2020 while continuing under the Ocean Infinity charter. The vessel operated primarily from Swire Seabed's headquarters in Bergen, Norway, serving as a base for coordinating global expeditions focused on high-resolution seabed surveys. During the charter period, Pacific Constructor supported Ocean Infinity's innovative approach to exploration, emphasizing the use of multiple AUVs for efficient, wide-area coverage of unmapped ocean floors, complemented by ROVs for detailed inspections. The operations aligned with Ocean Infinity's business model, particularly its "no find, no fee" structure for high-risk search and recovery projects, where compensation was contingent on successful outcomes. The multi-year contract supported a comprehensive scope of activities, including hydrographic surveys, environmental assessments, and exploratory missions, with the vessel accommodating up to 102 personnel to facilitate extended offshore deployments. This size allowed for integrated teams of surveyors, engineers, and technicians to manage the complex deployment and from AUVs and ROVs in water depths up to 6,000 meters. The charter concluded in early 2021, ahead of the original six-year term, as transitioned operations to its newly developed Armada fleet of robotic vessels designed for enhanced autonomy and sustainability. This shift marked a strategic pivot toward uncrewed and low-emission technologies, reducing reliance on traditional chartered support ships like Pacific Constructor.

Post-charter developments

Following the conclusion of its charter with in early 2021, the vessel, then known as Pacific Constructor, was returned to its owner, Pacific Offshore Operations Pte Ltd., based in . In April 2021, Swire Pacific Offshore sold the vessel to Dong Fang Offshore Co., Ltd., a of Hung Hua Construction Co., Ltd., for deployment in Asian offshore wind projects. Upon acquisition, it was initially renamed Constructor 1 and reflagged under , with MMSI 416007369. Subsequently, the vessel underwent a major refit in , completed in late 2021, converting it into 's first walk-to-work (W2W) vessel equipped with a motion-compensated gangway for safe access to offshore wind turbines. It was then renamed Orient Constructor and entered service in October 2021, chartered to a turbine manufacturer for commissioning and maintenance in , . As of 2025, Orient Constructor remains owned by Dong Fang Offshore Co., Ltd., operates under the flag, and is primarily engaged in offshore wind operations and maintenance (O&M) in Asian waters, with no reported involvement in deep-sea search missions.

Notable operations

Search for

In January 2018, the Malaysian government entered into a "no find, no fee" contract with Ocean Infinity, chartering the Seabed Constructor for a 90-day underwater search operation targeting an initial 25,000 km² area in the southern Indian Ocean, based on refined analysis of the flight's possible crash site north of the previous search zone. Under the agreement, Ocean Infinity would receive payment—up to US$70 million—only if wreckage was located, with rewards scaled by the size of the searched area in which the discovery occurred. The Seabed Constructor departed from Durban, South Africa, on January 2, 2018, carrying a team of approximately 65 crew members, including Malaysian military observers, and arrived in the search region near Perth, Australia, by late January to begin operations. The vessel deployed up to eight Kongsberg HUGIN autonomous underwater vehicles (AUVs), each capable of operating at depths up to 6,000 meters but focused on the 3,000–4,000 meter depths of the target seabed, to conduct high-resolution multibeam sonar mapping and synthetic aperture sonar imaging for debris detection. The search proceeded in multiple phases across several priority sites identified by drift and satellite data analyses, utilizing the AUVs' 48-hour endurance to cover up to 1,300 km² per day while the vessel provided real-time monitoring and data processing. By May 2018, after extending beyond the initial 90 days at the Malaysian government's request, the operation had surveyed over 112,000 km² of challenging terrain without locating any wreckage from MH370, leading to the contract's suspension on May 29. Although unsuccessful, the mission highlighted the Seabed Constructor's advanced capabilities in large-scale deep-sea surveys, informing subsequent MH370 discussions, including Ocean Infinity's 2025 renewal with a different vessel.

Discovery of ARA San Juan

In late September 2018, was contracted by the on a "no find, no fee" basis to search for the ARA San Juan, a TR-1700-class diesel-electric that had disappeared on November 15, 2017, during a training patrol in the South with 44 crew members aboard. The Seabed Constructor, 's multi-purpose offshore survey vessel, commenced operations in the search area off the coast of in early November 2018, having recently returned from its involvement in the prolonged search for in the . The contract allowed for up to 60 days of search efforts, with the company assuming the financial risk. The mission employed five autonomous underwater vehicles (AUVs) launched from the Seabed Constructor, equipped with side-scan sonar, synthetic aperture sonar, multi-beam echo sounders, and high-definition cameras to systematically map extensive seabed areas at depths ranging from 5 meters to 6,000 meters. On November 17, 2018, in the early hours, one of the AUVs detected an anomaly in a ravine approximately 500 kilometers east of Comodoro Rivadavia, near the Golfo San Jorge. Two work-class remotely operated vehicles (ROVs) were subsequently deployed to the site at a depth of 907 meters, capturing visual imagery that confirmed the wreckage as the ARA San Juan through identifiable sections including the hull, bow, stern, and sail, along with a debris field indicating an implosion. The discovery brought significant emotional closure to the families of the lost crew, who had endured a year of uncertainty following the submarine's sudden loss due to a catastrophic implosion beyond its crush depth of 600 meters. It also underscored the Seabed Constructor's operational versatility, demonstrating its rapid adaptability from deep-ocean aerial debris surveys to targeted submarine wreck location using advanced unmanned systems. The Argentine government later awarded a US$7.5 million reward for the successful find.

Search for French submarine Minerve

In June 2019, the French Ministry of Armed Forces contracted Ocean Infinity to conduct a search for the wreck of the Minerve, a Daphne-class diesel-electric submarine that sank with all 52 crew members on January 27, 1968, during a training exercise in the Mediterranean Sea off Toulon. This effort followed a decision by President Emmanuel Macron in late 2018 to resume investigations into the loss, prompted by appeals from the victims' families and advancements in deep-sea technology. The mission aimed to provide closure after decades of uncertainty, focusing on a search area approximately 45 kilometers southeast of Toulon where the submarine was last reported. The Seabed Constructor, Ocean Infinity's multi-purpose offshore vessel equipped with autonomous underwater vehicles (AUVs) and high-resolution synthetic aperture sonar, arrived at the site on July 16, 2019. Over the next five days, the vessel deployed multiple AUVs for systematic seabed mapping, covering a challenging deep-water environment with low sedimentation that preserved potential wreckage. On July 21, 2019, the team detected sonar contacts consistent with a submarine hull, and subsequent deployment of remotely operated vehicles (ROVs) confirmed the location of the Minerve at a depth of approximately 2,370 meters. The wreck was found broken into three major sections scattered over about 300 meters of seabed, likely due to implosion from extreme pressure during descent. This depth tested the operational limits of the ROVs and AUVs, requiring precise control to capture high-definition imagery without risking equipment failure. French naval authorities, in collaboration with the Service Hydrographique et Océanographique de la Marine (SHOM), reviewed the ROV footage and sonar data, officially confirming the identity of the wreck on July 22, 2019. The visual evidence included distinctive features of the Daphne-class design, such as the and hull markings, ruling out other debris. The operation's success highlighted the Seabed Constructor's advanced capabilities, including real-time data processing and integration of multiple unmanned systems, which enabled rapid identification in conditions that had thwarted prior searches. The discovery brought significant emotional relief to the families of the lost crew, allowing for a memorial ceremony and designating the site as a protected naval cemetery where the remains would not be disturbed. Armed Forces Minister Florence Parly described the find as "a success, a relief, and a technical feat," emphasizing its role in honoring the sailors and advancing understanding of the incident without immediate plans for salvage. President Emmanuel Macron echoed this sentiment, noting the importance of the recovery effort in providing long-overdue answers. The mission underscored the value of private-sector expertise in historical military recoveries, paving the way for further analysis of the sinking's cause through non-invasive surveys.

Discovery of SMS Scharnhorst

In 2019, the Seabed Constructor undertook a private expedition funded by the Falklands Maritime Heritage Trust to locate the wreck of the German armored cruiser in the waters southeast of the . Led by Falkland-born maritime archaeologist , the mission aimed to find the flagship of Vice-Admiral Maximilian von Spee's , which had been sunk during . The search built on earlier attempts dating back to 2014 and utilized advanced aboard the vessel operated by . The wreck was discovered on April 12, 2019, at a depth of 1,610 meters, approximately 98 nautical miles southeast of Port Stanley. Lying upright and largely intact on the seabed, the Scharnhorst had not been disturbed since its sinking on December 8, 1914, during the Battle of the Falkland Islands, where it was overwhelmed by British battlecruisers HMS Invincible and HMS Inflexible. Remotely operated vehicles (ROVs) deployed from the Seabed Constructor captured high-resolution images, revealing the ship's main turrets still in place and an extensive debris field. This discovery marked the first location of a major warship from , providing new insights into the battle that effectively ended German in the South Atlantic and resulted in the loss of over 860 lives aboard the Scharnhorst. Observations from the ROV surveys highlighted significant battle damage, including shell holes from British gunfire and an near the hull, underscoring the intensity of the engagement. The findings contribute to naval historical understanding by preserving the site's integrity as a war grave and enabling detailed analysis of early 20th-century warship construction and combat effects.

Other survey and construction missions

In addition to its high-profile search operations, Seabed Constructor performed routine inspection, maintenance, and repair (IMR) tasks, as well as subsea construction support including trenching and decommissioning for the oil and gas industry under Swire Seabed from its delivery in 2016 until the charter to Ocean Infinity later that year. The vessel's operations during this period focused on North European markets, including the North Sea, where it supported geophysical surveys and light construction activities to maintain subsea infrastructure. Following the end of the Ocean Infinity charter in 2021, the vessel returned to similar commercial roles under Swire Seabed management before its acquisition and refit by Dong Fang Offshore, emphasizing excavation, dredging, and survey work for subsea asset integrity. As part of its contract with Ocean Infinity, Seabed Constructor participated in the 2019 search for the sunken bulk carrier MV Stellar Daisy in the South Atlantic Ocean, departing from Cape Town on February 8 and locating the wreck at a depth of 3,461 meters within 10 days using a fleet of autonomous underwater vehicles (AUVs). The mission, commissioned by the South Korean government, successfully identified debris fields and supported subsequent recovery efforts, including the retrieval of the vessel's voyage data recorder in 2021. Beyond targeted wreck searches, the vessel contributed to broader seabed mapping initiatives in the North Sea and other regions through its advanced survey systems, aiding in geotechnical assessments and environmental monitoring for offshore energy projects during its Swire Seabed tenure. After acquisition by Dong Fang Offshore in 2021 and refit as Orient Constructor, the vessel has been deployed for offshore wind operations and maintenance (O&M) in Asia, particularly in Taiwan, where it serves as the country's first walk-to-work (W2W) vessel equipped for safe technician transfers to wind turbines via gangway and motion-compensated systems. Since entering service in 2022 following W2W trials, it has supported turbine inspections and geotechnical investigations for wind farm developments in challenging marine environments.
