Kongsberg Discovery has upgraded its Kongsberg Listen electromagnetic sensor system, setting new standards for inspections, surveys and knowledge acquisition in complex underwater environments.
Formerly known as Argeo Listen, the system has undergone comprehensive hardware and software enhancements, delivering much-improved data processing and visualisation capabilities. The platform agnostic technology is now available for a huge range of applications across the ocean science, defence, energy and minerals sectors, amongst others.
Accelerating innovation
Kongsberg Discovery acquired Argeo’s electromagnetic sensing technologies, and recruited its expert staff, in August 2025, and has since focused on integrating the solutions into its existing portfolio.
The system has already been integrated and extensively operated on Kongsberg’s HUGIN family of AUVs, demonstrating excellent results in commercial surveys, and is now being rolled out commercially. Next month’s Oceanology International in London marks its trade show debut as Kongsberg Listen.
Flexible approach
Users familiar with Argeo Listen will immediately recognise the significantly enhanced software environment, now tightly integrated with Kongsberg’s Blue Insight ecosystem. The upgraded suite enables streamlined, end‑to‑end workflows, delivering seamless data processing from raw electromagnetic measurements through to client‑ready information and visualisation within a common operational framework.
The flexibility of the system is also a key selling point, with ease of installation and use on an array of industry-essential platforms, from AUVs and ROVs through to towed sensing assets.
