Echo Surveyor IV configuration

Platform: Hugin 3000
Manufacturer: Kongsberg Maritime
Commercial Operator: Fugro Survey


Fugro’s latest addition to their Autonomous Underwater Vehicles (AUV) fleet is the Echo Surveyor IV which is a “ state of the art” Kongsberg Hugin 1000, specifically designed for high resolution and efficient survey operations in water depths down to 3000 metres. AUV’s are the ultimate choice of instrument platform for deep sea and remote surveys. Placing survey sensors onboard an AUV means the geophysical measurements take place close to the seafloor, dramatically improving data resolution and accuracy.

Engineering grade high resolution data
Echo Surveyor IV is the latest generation of Kongsberg Maritime Hugin 1000 depth rated to 3000m with a payload selected by Fugro to meet the demands of the offshore survey industry. Fugro’s Fleet of Kongsberg Hugin AUV’s are successfully proven in many deep water and often remote environments around the Globe. Use of such a proven survey platform and experience will provide enhanced productivity, continuity and reliability ensuring optimum adherence to project schedules.

The Hugin 1000 is a modular design with improved obstacle avoidance and we offer our clients the option of two sub-bottom profiers that best suits the geology. The AUV also has a LED illuminated Digital stills camera to identify seabed features of interest.

Kongsberg Maritime’s next generation multibeam echosounder the EM 2040 is now available with the Echo Surveyor IV. With improved resolution, this provides a substantial improvement from the EM 2000 used in deep-water HUGIN versions up to now.

Fugro own and operate five deep water Echo class AUV’s which are mobilised either from one of Fugro’s dedicated fleet of international survey vessels or from 3rd party charter ships.
