AUV Completes Record-Breaking Multi-Week Fully Autonomous Mission

Kongsberg Discovery has reached another milestone in the development of HUGIN Endurance Autonomous Underwater Vehicle (AUV) following a record setting multi-week fully autonomous mission.

After receiving a final navigation update from a pre-deployed transponder 10 hours into the dive, the 8-ton, 40ft, AUV operated completely independent of all human interaction and with no external navigation aiding for the duration of the sortie.

This mission was conducted at depths ranging from 50m to 3400m and met the advertised 1,200 nautical mile range. Most impressive of all, was that HUGIN Endurance returned with a position error of approximately 0.02% of total distance traveled.

The complex mission plan was designed to validate the design specifications of the AUV and put the vehicle through its paces in a real-world environment. The mission consisted of straight-line transits spanning 60-300nm legs and survey areas. The survey areas covered 36nm2 with very high resolution synthetic aperture sonar (SAS) imagery and bathymetry, using Kongsberg’s HISAS 1032 Dual Rx, in less than 48 hours. Camera imagery and laser profiling data was also collected, at altitudes down to 9m.

Espen Henriksen, Executive Vice President Uncrewed Platforms Division, said; “The success of this mission proves HUGIN Endurance’s shore-to-shore operational capability. Removing the need for a surface ship provides a huge savings to our customers, in both time and resources. We are proud of our exceptional team has been working very hard to add this capability to our AUV portfolio.”

Rich Patterson, Vice President of Sales, Uncrewed Platforms Division, added; “All credit goes to our phenomenal team of engineers and operators that have made HUGIN Endurance the most capable AUV on the market. The mission we’ve just completed validates the design specifications of the system and provides proof that our HUGIN autonomy framework is fully capable of performing complex multi-day missions with no human interaction. We are extremely excited about the vast operational capabilities we can bring to our customers with HUGIN Endurance.”
