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 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 price.
“This mission demonstrated that autonomous ocean mapping is not only attainable—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 impression.”
“As capability wants improve, Meta continues to put money into cutting-edge infrastructure applied sciences — and our subsea cable technique work is vital to those efforts,” he mentioned. “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, mentioned Saildrone.
Working beneath 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 refined sensors mixed with proprietary AI algorithms. These present a full image of the maritime setting 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 centered on gathering bathymetric knowledge alongside the established Anjana cable route and the lately surveyed Aurora route. This allowed the groups to straight evaluate the Saildrone Surveyor’s efficiency in opposition to conventional crewed survey vessels. Key operational metrics—route constancy, line preserving, 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 had been capable of dynamically re-task it to analyze options of curiosity, corresponding 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 staff aimed to reveal 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 house places of work, 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 standard vessel, highlighting the sustainability benefits of uncrewed techniques.

Saildrone seems to wider USV purposes
This demonstration paves the best way 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, 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, vice chairman 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 danger. As our fleet expands, we envision a world community of Surveyor USVs supporting offshore industries with secure, environment friendly, and scalable knowledge options.”
In Could, Saildrone closed a $60 million funding spherical. The firm mentioned it would use the funding to deliver its know-how to Europe to deal with the pressing want for maritime safety for vital infrastructure and wider protection purposes.
