In conjunction with the launch of its brand-new Mariner XL ROV, Deep Ocean Search (DOS) entered in a MoU with the Deep Sea Vision (DSV). DSV is a deep-water survey company using Autonomous Underwater vehicles (AUV) 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 riskz. 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.
