The ultimate end user is the Naval Oceanographic Office (NAVOCEANO), which acquires and analyzes global ocean and littoral data and provides specialized and oper- ationally significant products and services to all elements within the Department of Defense.

Kongsberg is introducing the portable shallow water

REMUS 100 AUV system to its equipment lease pool in

Aberdeen, Scotland, to complement the existing subsea rental inventory. The product already has a proven track record and introducing it into the rental marketplace will create opportunities for customers to use this technology to support and expand their subsea operational activities.

Kongsberg Maritime will begin offering the REMUS 100 for rent beginning in April of 2011.

We have developed a complete and portable mine local- ization and neutralization system. This spring we will on a vessel of opportunity demonstrate this capacity with

HUGIN 1000 and the Minesniper mine disposal weapon, the latter which is made by Kongsberg Defence

Systems.

Another new offering is a fully auto- mated multi sensor pipeline inspection system. In February 2011 a HUGIN 1000 vehicle equipped with HISAS 1030 synthetic aperture sonar,

EM3002 multibeam echo sounder and an optical camera with LED lighting, was used to inspect around 30 km of subsea pipeline in an 8-hour, two-pass mission: In the first pass, side-scan data from the HISAS 1030 sonar was used to detect and track the pipelines in real-time. Software for pipeline detec- tion and tracking extracted pipe-like features in the sonar images, with a high degree of robustness towards false detections. The PipeTracker software runs as a plug-in module in the standard HUGIN payload system. The vehicle control system in turn uses the iden- tified pipeline tracks to position the vehicle at an optimal range for HISAS imaging.

The whole process is fully automated inside the AUV and requires no operator intervention. In the second pass,

HUGIN followed the pipeline tracks identified in the first pass at low altitude and inspected the pipelines using the

EM3002 multibeam and the optical camera. After the mission, the recorded HISAS 1030 data was post- processed into high-resolution (4x4 cm) sonar images and bathymetry maps of the pipeline. Together with the opti- cal images and the multi-beam data recorded in the sec- ond pass, this gave a detailed view of the pipeline sur- roundings and the pipeline itself. The collected data was spectacular. The complete procedure was repeated the next day over another pipeline in a new 8-hour, two-pass mission. von Alt (left) & Jalving (right)

Our customers can look forward to continued improvements in the capabilities and performance of our AUVs as well as increased synergy within the HUGIN/REMUS AUV product lines.
