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 automobile, 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 decreasing threat and value.
“This mission demonstrated that autonomous ocean mapping is not only potential—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 enhance, Meta continues to spend money on cutting-edge infrastructure applied sciences — and our subsea cable technique work is vital to those efforts,” he mentioned. “Ocean mapping performs an necessary function, and the implications for subsea cable route surveys are profound.”
The businesses accomplished the 26-day survey between June and July 2024. In the course of the demonstration, the Saildrone Surveyor mapped greater than 4,500 km (2,796 mi.) of seabed. This included complicated topographies and difficult situations, and not using a port name or outdoors help, mentioned Saildrone.
Working below sail and motor-sail modes and geared up 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 refined sensors mixed with proprietary AI algorithms. These present a full image of the maritime surroundings 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 knowledge alongside the established Anjana cable route and the lately surveyed Aurora route. This allowed the groups to straight examine the Saildrone Surveyor’s efficiency in opposition to conventional crewed survey vessels. Key operational metrics—route constancy, line protecting, 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 automobile efficiency. The surveyors have been in a position to dynamically re-task it to research options of curiosity, comparable to seamounts and canyons, vital for route optimization. Beforehand restricted to crewed vessels, this functionality opens the door to extra agile, responsive, and distributed survey operations, Saildrone mentioned.
A vital 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 shopper representatives.
With the Surveyor, these folks can now carry out their work remotely from shore-based places of work or dwelling places of work, decreasing time away from household and minimizing the bodily and psychological pressure related to offshore deployments, mentioned Saildron. Moreover, the mission averted an estimated 243 tons of CO₂ emissions, over 50 instances lower than a standard 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 power, and nationwide hydrographic packages, in line with Saildrone. Future developments will deal with 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,” mentioned Brian Connon, vp of ocean mapping at Saildrone. “The Surveyor’s efficiency on this mission proves that we will ship high-resolution, deep-water bathymetry with a fraction of the gasoline, value, and threat. As our fleet expands, we envision a worldwide community of Surveyor USVs supporting offshore industries with protected, environment friendly, and scalable knowledge options.”
In Could, Saildrone closed a $60 million funding spherical. The firm mentioned it’s going to use the funding to carry its know-how to Europe to deal with the pressing want for maritime safety for vital infrastructure and wider protection functions.
