Saildrone Surveyor maps 4,500 km of seabed, marking a serious shift in ocean survey capabilities
In a landmark achievement for maritime expertise, Saildrone and Meta have efficiently accomplished a first-of-its-kind deep-water cable route survey utilizing an uncrewed floor automobile (USV). The 26-day mission happened within the North Atlantic throughout June and July 2024, utilizing the 20-meter Saildrone Surveyor.
This milestone proves that uncrewed programs can match conventional crewed survey vessels in information high quality and efficiency—whereas significantly decreasing environmental affect and operational danger.
Mapping the Seafloor with Autonomy
The Saildrone Surveyor mapped over 4,500 kilometers of seabed with out requiring a port name or exterior help. It operated in each sail and motor-sail modes and was outfitted with a Kongsberg EM304 MKII multibeam sonar system. The automobile achieved swath protection of as much as 10 kilometers in water depths as deep as 5,500 meters.
The mission centered on mapping bathymetric information alongside two subsea cable routes—Anjana and Aurora. This allowed direct comparability between the Surveyor’s efficiency and that of standard survey ships. In response to the mission crew, the Surveyor exceeded expectations in key efficiency areas, together with route constancy, line conserving, information transmission, and depth accuracy.
“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 information that matched legacy surveys with distinctive accuracy, all whereas working remotely and with minimal environmental affect.”
New Requirements in Distant Operations
The crew used the Saildrone Mission Portal and real-time satellite tv for pc communications to trace the USV’s efficiency. Operators may re-task the automobile mid-mission to research seafloor options akin to canyons and seamounts. This versatile method was beforehand solely doable with crewed vessels and opens new potentialities for responsive survey missions.
Along with bettering efficiency, the mission considerably diminished Well being, Security, and Environmental (HSE) dangers. Surveyors and engineers may work remotely from residence or workplace, decreasing the necessity for lengthy deployments and time away from households.
The mission additionally prevented an estimated 243 tons of CO₂ emissions—greater than 50 instances lower than emissions from an ordinary crewed survey vessel.
Wanting Forward: A Shift in Ocean Survey Technique
“This can be a turning level for deep-ocean survey,” mentioned Brian Connon, VP 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.”
Saildrone plans to increase its fleet of Surveyor USVs to help a variety of industries. These embody subsea telecom, offshore vitality, and nationwide hydrography packages. Future enhancements will deal with longer mission vary, climate resilience, and integration of applied sciences like AI navigation and expendable bathythermographs.
About Saildrone
Saildrone is a U.S.-based protection firm that gives maritime intelligence and uncrewed ocean survey options. Its USVs are outfitted with superior sensors and proprietary AI to ship real-time insights above and beneath the ocean floor. With over 2 million nautical miles sailed, Saildrone programs are utilized by governments and industrial shoppers world wide for border safety, hydrography, undersea infrastructure safety, and extra.
