US company Saildrone, Inc. has launched a 22m version of its uncrewed surface vehicles, known as saildrones.

Powered by wind and solar energy, saildrones are capable of extreme-duration missions of up to 12 months in the open ocean. This latest and largest version, the first in the Surveyor class of USVs, is called the Saildrone Surveyor, and carries sonar equipment capable of seafloor mapping down to 7,000m.

Coinciding with the start of the United Nations Decade of Ocean Science for Sustainable Development, the launch of the Saildrone Surveyor is claimed to present a paradigm shift in enhanced seabed mapping, which is currently done with very large and expensive manned ships. The Surveyor, uncrewed and powering its robust sensor suite by harvesting renewable energy, delivers an equivalent survey capability, but at a fraction of the cost and carbon footprint of a traditional survey ship.

"We are excited to see the launch of the Saildrone Surveyor," said Alan Leonardi, director of the NOAA Office of Ocean Exploration and Research. “NOAA is supporting the development and testing of this new uncrewed system because we are confident it will expand the capability of our existing fleet of ships to help us accelerate in a cost-effective way our mission to map, characterize and explore our nation’s deep ocean territory, monitor valuable fisheries and other marine resources, and provide information to unleash the potential of our nation’s Blue Economy.”

In 2019, NOAA provided a three-year grant through the National Oceanographic Partnership Program to the University of New Hampshire, in partnership with the Monterey Bay Aquarium Research Institute and Saildrone, to integrate and test sensors on the Saildrone Surveyor for mapping the seafloor and revealing life in the water column. While conducting the mapping, samples of DNA, referred to as "environmental DNA," will be collected to reveal the genetic composition of organisms inhabiting the water.

“The launch of the Surveyor is a huge step up, not just for Saildrone’s data services but for the capabilities of uncrewed systems in our oceans,” said Richard Jenkins, founder & CEO of Saildrone. “For the first time, a scalable solution now exists to map our planet within our lifetime, at an affordable cost.”
