Kongsberg Maritime 3D Monitoring

Posted by Irina Tabakina

Kongsberg Maritime launched a new solution for the detection of scouring, corrosion, deformation and marine growth, which can destabilize wind turbines and underwater structures. The new K-Observer system, which is part of Kongsberg Maritime’s Modular Subsea Monitoring Network (MSM), is designed to provide accurate, remote hydroacoustic 3D monitoring using the Dual Axis Scanning Sonar (DAS) to continuously monitor the seabed and the substructure.
The 3D point cloud data created by the DAS is logged and transmitted to shore via the telemetry infrastructure of the K-Observer System (cabled, wireless or satellite) installed on the turbine. The system is designed for long-term installations and performs fully autonomously, from sensor control, data acquisition, to data processing, presentation of results and issuing of alarms (e.g. by text message or email).
K-Observer scans and interprets the condition of the seabed around the base of the structure (scouring and sediment displacement), as well as the state of the substructure itself (deformation, marine growth and corrosion) so people on shore can initiate immediate action or preventative maintenance if required.
