Saildrone Inc., in partnership with Meta, this week introduced that it has accomplished a deep-water cable route survey within the North Atlantic utilizing the Saildrone Surveyor, a 20-m (65.6 ft.) uncrewed floor car, or USV. The corporate mentioned the demonstration proves that autonomous platforms can ship knowledge high quality and efficiency on par with conventional crewed survey vessels whereas lowering danger and value.
“This mission demonstrated that autonomous ocean mapping isn’t just doable—it’s right here, and it’s extremely efficient,” mentioned Andy Palmer-Felgate, subsea cable engineer at Meta. “Saildrone delivered knowledge that matched legacy surveys with distinctive accuracy, all whereas working remotely and with minimal environmental influence.”
“As capability wants improve, Meta continues to spend money on cutting-edge infrastructure applied sciences — and our subsea cable technique work is important to those efforts,” he mentioned. “Ocean mapping performs an vital function, and the implications for subsea cable route surveys are profound.”
The businesses accomplished the 26-day survey between June and July 2024. Throughout the demonstration, the Saildrone Surveyor mapped greater than 4,500 km (2,796 mi.) of seabed. This included advanced topographies and difficult circumstances, and not using a port name or outdoors help, mentioned Saildrone.
Working underneath sail and motor-sail modes and outfitted with a Kongsberg EM304 MKII multibeam sonar, Surveyor achieved swath protection of as much as 10 km (6.2 mi.) in water depths of as much as 5,500 m (3.4 mi.), the firm mentioned.
Alameda, Calif.-based Saildrone’s USVs use subtle sensors mixed with proprietary AI algorithms. These present a full image of the maritime atmosphere above and beneath the ocean floor.
The Voyager USV earned Saildrone a 2025 RBR50 Robotics Innovation Award for mapping beforehand unexplored areas of the Gulf of Maine.
Surveyor exceeds expectations
The demonstration targeted on accumulating bathymetric knowledge alongside the established Anjana cable route and the just lately surveyed Aurora route. This allowed the groups to instantly examine the Saildrone Surveyor’s efficiency towards conventional crewed survey vessels. Key operational metrics—route constancy, line holding, knowledge transmission, and depth accuracy—met or exceeded expectations throughout the board, Saildrone mentioned.
Utilizing the Saildrone Mission Portal and real-time, high-bandwidth satellite tv for pc connectivity, Saildrone hydrographic surveyors and pilots monitored car efficiency. The surveyors have been in a position to dynamically re-task it to analyze options of curiosity, similar to seamounts and canyons, important for route optimization. Beforehand restricted to crewed vessels, this functionality opens the door to extra agile, responsive, and distributed survey operations, Saildrone mentioned.
A important focus of the mission was minimizing well being, security, and environmental (HSE) dangers related to offshore operations. The staff aimed to display vital advantages to the standard of life for hydrographic surveyors, cable route engineers, and consumer representatives.
With the Surveyor, these individuals can now carry out their work remotely from shore-based workplaces or residence workplaces, lowering time away from household and minimizing the bodily and psychological pressure related to offshore deployments, mentioned Saildron. Moreover, the mission prevented an estimated 243 tons of CO₂ emissions, over 50 occasions lower than a traditional vessel, highlighting the sustainability benefits of uncrewed programs.

Saildrone seems to wider USV functions
This demonstration paves the best way for broader adoption of USVs in subsea telecommunications, offshore vitality, and nationwide hydrographic packages, based on Saildrone. Future developments will concentrate on increasing operational vary, bettering climate resilience, and integrating new applied sciences like AI-based navigation and expendable bathythermographs.
“It is a turning level for deep-ocean survey,” mentioned Brian Connon, vp of ocean mapping at Saildrone. “The Surveyor’s efficiency on this mission proves that we are able to ship high-resolution, deep-water bathymetry with a fraction of the gasoline, price, and danger. As our fleet expands, we envision a world community of Surveyor USVs supporting offshore industries with protected, environment friendly, and scalable knowledge options.”
In Might, Saildrone closed a $60 million funding spherical. The firm mentioned it would use the funding to convey its know-how to Europe to handle the pressing want for maritime safety for important infrastructure and wider protection functions.
