Geared up with a set of superior sensors, Surveyor delivers real-time intelligence, surveillance, and reconnaissance (ISR) above and beneath the floor. | Supply: Saildrone
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 stated the demonstration proves that autonomous platforms can ship information high quality and efficiency on par with conventional crewed survey vessels whereas lowering threat and value.
“This mission demonstrated that autonomous ocean mapping isn’t just attainable—it’s right here, and it’s extremely efficient,” stated Andy Palmer-Felgate, subsea cable engineer at Meta. “Saildrone delivered information that matched legacy surveys with distinctive accuracy, all whereas working remotely and with minimal environmental impression.”
“As capability wants improve, Meta continues to spend money on cutting-edge infrastructure applied sciences — and our subsea cable technique work is essential to those efforts,” he stated. “Ocean mapping performs an vital position, 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 situations, with no port name or exterior help, stated 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 stated.
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 gathering bathymetric information alongside the established Anjana cable route and the lately surveyed Aurora route. This allowed the groups to instantly examine the Saildrone Surveyor’s efficiency in opposition to conventional crewed survey vessels. Key operational metrics—route constancy, line conserving, information transmission, and depth accuracy—met or exceeded expectations throughout the board, Saildrone stated.
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, essential for route optimization. Beforehand restricted to crewed vessels, this functionality opens the door to extra agile, responsive, and distributed survey operations, Saildrone stated.
A essential focus of the mission was minimizing well being, security, and environmental (HSE) dangers related to offshore operations. The group aimed to display important advantages to the standard of life for hydrographic surveyors, cable route engineers, and consumer representatives.
With the Surveyor, these folks can now carry out their work remotely from shore-based workplaces or house workplaces, lowering time away from household and minimizing the bodily and psychological pressure related to offshore deployments, stated Saildron. Moreover, the mission prevented an estimated 243 tons of CO₂ emissions, over 50 instances lower than a traditional vessel, highlighting the sustainability benefits of uncrewed methods.

Saildrone appears to wider USV functions
This demonstration paves the way in which for broader adoption of USVs in subsea telecommunications, offshore power, and nationwide hydrographic applications, in accordance with Saildrone. Future developments will give attention to increasing operational vary, enhancing climate resilience, and integrating new applied sciences like AI-based navigation and expendable bathythermographs.
“It is a turning level for deep-ocean survey,” stated 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 gas, price, and threat. As our fleet expands, we envision a world community of Surveyor USVs supporting offshore industries with protected, environment friendly, and scalable information options.”
In Might, Saildrone closed a $60 million funding spherical. The firm stated it would use the funding to convey its know-how to Europe to deal with the pressing want for maritime safety for essential infrastructure and wider protection functions.
