Deep Ocean Search, and Deep Sea Vision, specialist of worldwide solutions in ultra-deep-water activities launches common solutions AUV (Autonomous Underwater Vehicle) and new ROV (Remotely Operated Vehicles) 19,700 feet (6,000m) depth rated
USA – 10 July 2025
Memorandum of Understanding (MoU) between Deep Ocean Search and Deep Sea Vision
In conjunction with the launch of its brand-new Mariner XL ROV, DOS ltd entered MoU with the US company Deep Sea Vision (DSV).
DSV is a deep-water survey company using Autonomous Underwater vehicles such as Kongsberg Hugin 6000 able to dive at 6,000msw depth with a long track record in the deep ocean space.
Through combined efforts to common clients DSV and DOS can offer AUV+ROV services from the same platform with shared multirole personnel. Minerals survey, O&G industry or NOG those looking for turnkey solutions are offered full operational solutions of inspection/sampling down to 6000m
This very compact spread reduces mobilization costs and support vessel specifications, for a lower carbon footprint, less people and less risk
DSV and DOS redefine the standards of deep-sea operations by combining technology, precision and simplicity.
SIMPLIFIED CONTROL OF DEEP-WATER OPS
With Mariner XL, Deep Ocean Search (is offering for hire a 6000msw capable WROV which can be mobilized quickly and easily for rapid deployment anywhere in the world: a launch & recovery system, an ultra-long range inertial and acoustic positioning system, a pilot station and a store space, all in only 4 x 20’ containers. Deployment on board requires no major structural modifications of the support vessel and no calibration. The Argus Mariner XL is a light work-class ROV designed ultra-deep operations, inspection, sampling, object recovery, imaging and data acquisition.
Mariner XL deepwater WROV is offering Deep Ocean Search Ltd clients a full range of services based on our 20 years of experience in deepwater projects. Capable of reaching depths of up to 6,000 msw, it is an advanced piece of equipment used for subsea operations (survey, IMR, construction…) in various industries, including oil & gas, field inspection, minerals survey or sampling, scientific research and military applications.
Nicolas Vincent, Operations Manager of DOS comments about this launch: “ following recent launch of our new Mariner XL ROV, we are very happy of the opportunity to join forces with Deep Sea Vsion who share same philosophy of operations than DOS. Our latest generation of assets (ROV + AUV) will be offering for hire a 6,000msw capable solution which can be mobilized quickly and easily for rapid deployment anywhere in the world. This joined effort shows our common concept that unites everyone at DOS: team spirit and teamwork.”
Tony Romeo, CEO of DSV comments: The opportunity to team with DOS in the commercial sector continues in Deep Sea Visions focus on autonomy in the very deep ocean sector. Traditionally clients will consider operations with multiple vessels. With the trust in our autonomous vehicles, they can run independently from the mothership allowing concurrent ROV operations. The cost saving and faster access to data can then be passed directly to the end clients.
READY FOR SUBSEA and SURVEY SERVICES
DOS carrying out survey services for various industries such as Oil & Gas: Geophysical acquisitions, photogrammetry, metrology, sampling, rig move or ROV survey/sampling, field development/construction survey, subsea structure inspection, TDP monitoring, pre-lay/post lay survey, debris survey, and, out of Straightness survey. It is a pioneer in deep water survey, salvage and positioning, providing unique expertise to its customers with long track record on deep water heavy subsea operations, such as salvage for the industry, government, NOG, and private clients. As a seasoned project manager, DOS is able to supply consultancy, R&D and engineering for its clients. DOS has manufactured the first Full Ocean Depth (11.000m depth rated) Side scan, supported launch of the first swarm of AUVs Hugin6000 (up to 8 vehicles), supported integration of Geotech devices on crewless vessels (78m length) and creating Full Ocean Depth subsea tracking for manned submarine.
Deep Sea Vision (DSV) comprises a team of seasoned subsea professionals gathered to perform selected operations for targeted specialized clientele. The core of the search technology is the latest in deepwater mapping equipment based upon the Kongsberg HUGIN 6000 Autonomous Underwater Vehicle (AUV) platform. The main search sensor for this system is the cutting-edge Kongsberg Maritime HiSAS 1032 Synthetic Aperture Sonar (SAS) system. implementing the HiSAS is the EM2040 Bathymetric mapping sonar, CathX Color Camera/Laser permitting final optical imaging of targets, Sub Bottom Profiler 2-16kHz for sub surface stratification and magnetometer for magnetic anomalies both geological and man made. This vehicle also houses an extended environmental section to integrate any 3rd part sensor a client may request.

About Deep Ocean Search
Deep Ocean Search is an innovative and inventive company providing worldwide solutions in ultra-deep-water activities and/or subsea operations (survey, IMR, construction…) in various industries, including oil & gas, field inspection, minerals survey or sampling, scientific research and military applications.
DOS hold four world records, including the recovery of the world’s deepest cargo of silver coins from the wreck of SS City of Cairo (100T) on behalf of the U.K. government; supported the location of the fighter plane of Antoine de Saint-Exupéry; and, worked with explorer Victor Vescovo to discover the world’s deepest wreck: the USS Samuel B. Roberts, a World War II destroyer escort found 22,621 feet (6,895 meters) deep in the Philippine Sea. They have also located the missing naval submarines AJA San Juan and La Minerve and helped investigate significant air accidents, including Air France AF447 in 2009, Malaysia Airlines Flight MH370 in 2014 and EgyptAir Flight MS804 in 2022. Operations are led by Nico Vincent. He worked for over three years to plan the search and discovery of Sir Ernest Shackleton Endurance in Antarctica. He created unique procedures for subsea operations, chose new, never-before-used technology and developed all operations plans for the project. Vincent co-authored with Dr. John Shears the National Geographic book “Endurance: The Discovery of Shackleton’s Legendary Ship,” Vincent is a member of The Explorer Club, who awarded their prestigious Citation of Merit in 2024 on behalf of the Endurance22 team for the discovery of Endurance.
DOS operates at extreme depths on a daily basis and has been doing so for more than 10 years. The company was created in 2010 to fulfill a wide range of survey and subsea operations in water depths of up to six thousand meters. Specially adapted survey vessels and robotic systems were brought together with a highly experienced team. DOS’s unique capabilities are made available to other organizations that want to operate in ultra-deep water. DOS operates at extreme depths (up to 11000m) on a daily basis, 24 hours a day, offering advanced subsea services worldwide from shallow to ultra-deep areas. Find out more at deepoceansearch.com

(https://www.latimes.com/california/story/2024-01-30/amelia-earhart-plane-deep-sea-exploration-company)
- Completed mineral survey projects in Cook Islands and around American Samoa – groundbreaking work which involved using SAS to identify polymetallic nodules.
- Completed search in treacherous ravines and cliffs around American Samoa for missing aircraft and collected more data on sea floor composition.
- Completed long term training for Pacific Island government on use of deep sea AUVs.
- Oil and gas work in the Atlantic Ocean for large oil companies.
DSV is led by Craig Wallace as President of Operations. Craig was the former product manager at Kongsberg Maritime for the HUGUN line of products – the world’s best deep ocean sonar equipment. Taking ground-breaking work Kongsberg Maritime allows Deep Sea Vision to conduct commercialization of what was predominantly military grade technology Craig has published white papers and academic papers in the industry and is well know for leading high end projects such as the X-Prize mapping competitions.
