Saildrone, a developer of autonomous unmanned surface vehicles (USVs) for maritime operations, has registered its first four Saildrone Voyager USVs in Denmark, allowing them to operate under the Danish flag.
The registration was completed in cooperation with the Danish Maritime Authority (DMA), which worked with Saildrone to develop a regulatory framework for registering and operating uncrewed surface vehicles under the Danish flag.
The four 10-meter Voyager USVs will operate under the Danish flag as Saildrone expands its operations across Europe. The company said the registration provides a formal flag-state framework for its USVs operating internationally.
For Saildrone, registration under the Danish flag establishes a formal regulatory foundation for continued expansion across Europe, supporting a growing fleet and deeper operational integration with European customers.
The registration builds on Saildrone’s history of integrating USVs into established maritime regulatory structures. Saildrone is the only company to have achieved classification from a class society—the American Bureau of Shipping—for autonomous unmanned surface vehicles and to have achieved flag-state registration.
Unlike classification, which involves an independent technical assessment of a vessel, flag-state registration establishes the national regulatory framework under which a vessel operates.
The Danish Maritime Authority said the registration demonstrates Denmark’s efforts to develop practical regulatory approaches for emerging maritime technologies.
“We are pleased that Saildrone has chosen Denmark as the flag state for the company’s uncrewed vessels. This underscores that Denmark, as a leading maritime nation, has both the willingness and the ability to manage and certify future maritime technologies," said Brian Adrian Wessel, director general of the Danish Maritime Authority.
"At the same time, the registration serves as a strong example of the work carried out through the DMA Regulatory Future Lab, where we collaborate with industry to develop safe and practical solutions when new maritime technologies challenge existing regulations. As a regulatory authority, we must create room for innovation, and this is one way we can do so."
This summer, Saildrone Europe established a permanent headquarters in Copenhagen and announced partnerships with three European companies—Van Der Valk Shipyard in the Netherlands, Umoe Mandal in Norway, and Southern Spars in Poland—to create greater production capacity for regional customers.
Earlier this year, Saildrone completed a six-month mission in the Baltic Sea, supporting the Royal Danish Navy. During that time, Saildrone detected more than 170,000 unique vessels, sailed over 20,000 nautical miles, and achieved 92% uptime across its fleet under a range of harsh weather and sea states.
