Groundbreaking Fisheries Research Conducted by Exail’s DriX Uncrewed Surface Vessel at US Offshore Wind Sites
March 8, 2024, Written by Zerina Maksumic
Exail’s DriX uncrewed surface vessel (USV) has recently completed a pioneering fisheries research survey to evaluate the impact on biomass and fish stock before, during, and after the construction of offshore wind farms in the United States.


Conducted off the coasts of Massachusetts, Rhode Island, and New York, the survey was carried out for the NOAA Fisheries Northeast Fisheries Research Science Center (NEFSC) in conjunction with NOAA USxOC, Kongsberg, and Nortek.
The DriX USV was equipped with a SeapiX-R 3D high-resolution multibeam echosounder from Exail, two Kongsberg EK80 single-beam echosounders, and a Nortek ADCP.
The objective of the operations was to gather data on ocean conditions, marine life, and seafloor structures within both existing and future offshore wind farm areas utilizing various scientific sensors such as sonars and echosounders.
By collecting information at proposed turbine locations, NOAA can analyze environmental changes pre and post turbine installation.
Operating under supervised autonomous mode, the DriX USV covered over 5,000 kilometers of navigation lines, maintaining a distance of 20 meters from wind farm monopiles while avoiding obstacles like ships, fishing nets, and buoys.
Data was transmitted to the remote operation center (ROC) located at the University of Rhode Island’s Inner Space Center in Narragansett, Rhode Island, as well as Exail’s Maritime Autonomy hub in La Ciotat, France.
“We extend our gratitude to NOAA Fisheries Northeast Fisheries Research Science Center for their confidence in Exail’s USV and sensors,” stated Shayan Haque, Business Development Manager at Exail.
“We take pride in delivering highly precise scientific data to our clients, ranging from biomass identification in the water column to the intricacies of sand displacement bathymetry.”
Exail highlighted their cooperation with the U.S. Coast Guard Sector Southeast New England, wind farm developers, and local mariners to ensure the safe autonomous operation of the system within busy shipping channels and intricate wind farm construction areas.
According to the company, the DriX USV executed its mission with minimal environmental impact, achieving a 90% reduction in CO2 emissions compared to traditional survey vessels.
The DriX USV, developed by iXblue and ECA Group under the Exail joint brand, has obtained Approval in Principle (AiP) from Bureau Veritas and certification from Lloyd’s Register.
