Kongsberg Discovery Announces Echo Sounder Upgrade

the expense and time needed for repeated CTD probes. In addition, improved understanding of sound propagation serves as important input for various acoustic instruments used for water-column object detection.Seabed classification and suspended sediments in water columnThe EK80 is the only calibrated broadband acoustic system that can measure backscatter to provide absolute values across sites and sensor platforms. Serving as a supplement to high-resolution seafloor mapping systems, the EK80 provides valuable information required to classify seafloor composition from acoustic surveys. In addition, recent

Kongsberg Discovery Launches HiPOS – HiPAP Positioning Software

essentially splits the workload of Kongsberg Discovery’s HiPAP systems, with the positioning and processing managed onboard the vessel processor, while a client user interface is run remotely over a lower bandwidth VPN connection. The remote connection can be via satellite, 4G, 5G or Maritime broadband radio.The user interface can also be operated directly on the vessel, as in a traditional setup, whilst at the same time having the option for shore-based operators to log in and take over for a shift, or provide expert support.Spencer Collins, Vice President for Sales, Kongsberg Discovery, comments:

Harvest, 3D at Depth Team in North Sea Project

;s Harvest Technology Group Limited completed a milestone project in the North Sea, partnering with LiDAR technology provider 3D at Depth to deliver remote metrology services for a global subsea services company. The entire operation was conducted with less than 1Mbs of bandwidth and usedboth 4G (broadband cellular network) and VSAT (two-way satellite) connectivity. “We chose Harvest because the technology provides high-fidelity, two-way audio communications, frame-synchronized video, and optimal bandwidth efficiency. This was essential in providing our remote personnel onshore with the
