![]() ![]() Furthermore, the stability of the HUGIN platform and the ability to simultaneously operate both at high speed and at low altitude resulted in an efficient survey with crystal clear images from the onboard optical camera. The greater speed of the HUGIN 1000 compared to that of a ROV meant that 60km of pipeline could be inspected in a little over 16 hours during the two passes. The complete procedure was repeated the next day over the second pipeline in a new 8-hour, two-pass mission.īoth pipelines were surveyed at a constant speed of 4 knots and at 4-25m altitude, depending on the sensor in use. Together with the optical images and the multi-beam data recorded in the second pass, this gave a detailed view of the pipeline surroundings and the pipeline itself. After the mission, the recorded HISAS 1030 data was post-processed into high-resolution (4x4 cm) sonar images and bathymetry maps of the pipeline. In the second pass, HUGIN followed the pipeline tracks identified in the first pass at low altitude and inspected the pipelines using the EM 3002 multibeam and the optical camera. ![]() The whole process is fully automated inside the AUV and requires no operator intervention. The HUGIN 1000 control system in turn uses the identified pipeline tracks to position the vehicle at an optimal range for HISAS imaging. Norwegian Research Council, runs as a plug-in module in the standard HUGIN payload system. The PipeTracker software, which was developed in a collaborative effort with the Norwegian Defence Research Establishment (FFI) in a project funded by the In the first pass, side-scan data from the HISAS 1030 sonar was used to detect and track the pipelines in real-time, using PipeTracker software for pipeline detection and tracking extracted pipe-like features in the sonar images, with a high degree of robustness towards false detections. The instruments were used to inspect around 30 km of subsea pipeline in an 8-hour, two-pass mission. The HUGIN 1000 AUV was equipped with a an advanced suite of KONGSBERG imaging equipment including the HISAS 1030 synthetic aperture sonar, EM3002 multibeam echo sounder and an optical camera with LED lighting. The subject of the inspection was two subsea pipelines going to the Mongstad oil refinery. The pipeline inspection took place February 9th ? 11th 2011, in the Hjelte fjord near Bergen, Norway and the HUGIN 1000 was operated from the Royal Norwegian Navy vessel HNoMS Maloy.

Whether it is long-range military survey wide-area mine detection, classification and identification or even patrolling a choke point listening for submarines, this extended range capability offers new solutions to existing and future challenges. KONGSBERG has added its Maritime Broadband Radio (MBR) communications system to HUGIN Endurance’s payload, allowing it to surface and share large quantities of data swiftly with any suitably equipped installation, such as another vessel, shore station or a wind turbine fitted with an MBR antenna.įor defense applications, HUGIN Endurance makes persistence a reality. Shore-to-shore operations offer the opportunity to reduce carbon footprint for commercial activities and yet retain unrivaled data resolution and accuracy. This longevity allows HUGIN Endurance to undertake extensive missions without the support of a mothership. Named HUGIN Endurance, the new AUV boosts operational duration to approximately 15 days, enabling extended survey and inspection missions far from shore. Kongsberg Maritime has launched the next generation of its advanced HUGIN AUV. ![]()
