Review of Autonomous Undersea Vehicle (AUV) Developments 
HUGIN 3000 [17,18,19,20,21] 
The HUGIN 3000 is the new and third generation of the HUGIN vehicles that were developed 
and operated in partnership with the Norwegian oil company, Statoil, the Norwegian Defense 
Research Establishment (FFI), and Norwegian Underwater Intervention (NUI). The HUGIN 
(figures 13, 14) project started in 1995, and the HUGIN vehicles have now performed more than 
100 missions, including several commercial pipeline route surveys for Statoil in Norwegian 
waters. The HUGIN vehicles have so far proven very cost effective and will enhance quality of 
survey data compared to existing methods. 
The Hugin 3000, rated to 3000 meters, is 5 meters 
long and powered by a state-of-the-art aluminum 
oxygen fuel cell, providing a mission capacity of 
up to 48 hours before resurfacing. The AUV will 
carry a variety of sensors, including the EM 2000 
multibeam echo sounder for bathymetry and 
imagery. Underwater positioning will be | 
performed using a HiPAP® Super Short Base Line 
(SSBL) system integrated with Doppler speed log, 
Inertial Navigation System, and for surface 
reference, Differential Global Positioning System eX Bsus 
(DGPS). Acoustic links for control of the AUV, reading of Figure 13. HUGIN 3000 Recovery 
sensor data, and emergency control are part of the 
delivery. 
C&C Technologies, an international hydrographic surveying company, has acquired and plans 
to use the HUGIN AUV as a deep-water survey tool for Minerals Management Service (MMS) 
Pipeline Hazard Surveys and Block Surveys. The HUGIN will provide the customer with 
engineering quality bathymetry data for the design of pipelines, pipeline risers, templates, and 
other sea floor equipment. 
Kongsberg Simrad's new deep-water dynamic Be==—= 
positioning (DP) and vessel-control functions and 
systems for the company's SDP/SVC/STC systems 
are designed to improve the safety and reliability of DP 
operations in deep water. These functions are 
enabling AUVs to be used for drilling, production, 
testing, and _ intervention operations that are 
traditionally accomplished with moored systems. [iipssssgaaeme ; - *s,

and designed to improve drilling, workover, and completion of operations in deep water. 
These developments by Kongsberg Simrad are demonstrating that AUVs not only have 
significant cost advantages over current methods, but can also reliably undertake commercial 
survey work. Due to inherent low noise and high stability, HUGIN 3000-acquired survey data
