Deep Ocean Search (DOS) Adds The Sabertooth Hybrid ROV/AUV To Its Fleet
DOS announces planned upcoming integration of a Saab Seaeye Sabertooth 3,000msw hybrid ROV/AUV into its operational fleet. Available from Q3 2026, the Sabertooth extends DOS’s subsea service portfolio alongside the Mariner XL WROV and, in cooperation, Hugin 6000 AUV, offering industry a rapidly deployable platform for survey, inspection and IMR from nearshore to 3,000msw depth.
An Industrial platform for every sector. The Sabertooth is a high-performance industrial tool. DOS will deploy it for:
• Oil & Gas: pipeline & riser inspection, pre-/post-lay survey, CP measurement;
• Marine Renewable Energy: wind farm foundation inspection, cable route survey, scour & mooring monitoring;
• Hydrography & Geophysics: MBES bathymetry, SSS, SBP, magnetometry, seabed characterization, UXO survey;
• Positioning & Metrology: acoustic/inertial positioning, spool metrology, dimensional control;
• Photogrammetry & 3D imaging: structure documentation, 3D modeling;
•
Defence & Science: object location, strategic surveys, scientific expeditions, under-ice operations.
“The addition of the Sabertooth to the DOS fleet is part of a broader strategy to offer industry the widest possible range of subsea survey and inspection capabilities from a single, experienced operator.
“DOS already operates two complementary platforms, each addressing a distinct segment of the market.” Nicolas Vincent, Head of Operations, Deep Ocean Search

A true hybrid: AUV And ROV in one.
The Sabertooth operates in both fully autonomous AUV mode (long-range survey missions, up to 50 km per dive, ~20 h endurance) and tethered ROV mode (real-time video, close-range inspection, intervention) — switchable within the same deployment. Six vectorized thrusters deliver full 6 DOF manoeuvrability, forward speed to 4 knots, and auto depth/altitude/ heading. The SaberAvoid obstacle- avoidance system enables safe autonomous navigation in complex environments. Payload capacity supports MBES, SSS/SBP, SAS, CP arrays, magnetometer, photogrammetry heads and custom sensors.
“The Sabertooth gives us an industrial- grade AUV that we can put in the water quickly, configure for the client’s specific survey or inspection requirements, and operate from nearshore all the way to 3,000 metres. For offshore energy, cable operators, port authorities, defence clients or scientific institutions — anyone who needs precise, autonomous or tethered subsea data acquisition — this vehicle is a serious working tool, not only an exploration unit.”
