Our Sirena Autonomous Underwater Vehicles - AUV / marine robot offer the ultimate in autonomous remote subsea survey capability. These free-swimming autonomous underwater vehicles are characterized by great maneuverability and high accuracy of stabilization. Hydrodynamic shape, accurate instruments and excellent battery capacity makes these AUV's ideal choices.

Sirena is available in several configurations and depth ratings. The main depth ratings are:

3000 meter
4500 meter
6000 meter

Because our HUGIN autonomous underwater vehicles can function without tethers, cables, or remote control, they have a multitude of applications in oceanography, environmental monitoring, and underwater resource studies. A key element in the HUGIN concept is the application of a common technology that makes the systems adaptable for navy and commercial applications. Our modular design allows different payload configurations, depending on the customers needs.
