KONGSBERG, Norway – C-Innovation (C-I), a member of the Edison Chouest Offshore group of companies, has signed an agreement with Kongsberg Maritime to acquire four new autonomous underwater vehicles (AUV). The order adds AUV capabilities to its ROV fleet.
The Kongsberg Maritime AUV delivery includes two HUGIN AUVs and two MUNIN AUVs. The HUGINs are depth rated to 4,500 m (14,763 ft) and equipped with the latest generation of HISAS 1032, Kongsberg Maritime’s Synthetic Aperture Sonar (SAS). They also carry an EM 2040 multibeam echo sounder, sub-bottom profiler, color still image camera and laser profiler. The MUNIN AUVs are rated to 1,500 m (4,921 ft) and equipped with a Kongsberg Maritime EM 2040M multibeam echo sounder, sidescan sonar, sub-bottom profiler and color still image camera.
The new AUVs are specially designed for subsea inspection, mapping and pipeline surveys. They feature autonomous pipeline tracking software, developed by Kongsberg Maritime, enabling the AUV to track and follow alongside a pipe using either the SAS or sidescan. The vehicles can also fly directly overhead a pipe, tracking it with the EM 2040 to collect high resolution bathymetry, photo imagery, and a laser profile of the pipe.
The company said that this purchase allows it to complete more advanced and faster surveys in deeper water.
Richard Bourque, general manager of C-Innovation, said: “We can now offer HiSAS data from the 4,500 m HUGIN to the offshore industry. All vehicles are portable to some extent but especially the MUNIN vehicles can be mobilized anywhere in a very short time.”
The HUGIN includes swappable batteries and removable data storage. The C-I MUNINs have a fast charge system and data download facility designed to maximize productivity and minimize down-time between dives. They are also supplied with the Kongsberg Maritime Reflection AUV post-mission analysis software.
In-mission supervision including real-time data transmission and position aiding is provided by Kongsberg Maritime’s HiPAP acoustic system. The position solution is calculated by NavLab navigation post-processing software.
