Analytics System for Subsea Power Cable Maintenance Launched
Indeximate, a provider of fiber sensing-based subsea power cable health monitoring to the offshore wind energy industry, has officially launched its Scattersphere® platform.Scattersphere is a non-intrusive, hardware-agnostic solution to replace one-off alarms with analysis of continuous health behavior and highlight cable failure risks before they become a threat to asset integrity.Proprietary data compression technology allows Scattersphere to access and analyze petabytes of data stored in the cloud without loss of fidelity and to continually process long-term risk profiles for monitored cables.
Advanced Navigation Unveils Compact Boreas 50 Series
Advanced Navigation has announced the expansion of its Boreas range with the new 50 series - the company’s most compact fiber-optic gyroscope (FOG) inertial navigation system (INS), delivering rapid North-seeking in challenging GNSS-denied maritime environments.The 50 Series includes two high-performing variants: the A50 - an attitude and heading reference system (AHRS), and the D50 - a strategic-grade INS.Each is equipped with a North-seeking gyrocompass capable of rapidly determining true North. Powered by Advanced Navigation’s advanced sensor fusion, the series delivers intelligent
Offshore Industry Majors Join Forces for Next-Gen Subsea Flowline Tech
breakthrough in subsea pipeline heating, offering significant cost savings, improved efficiency, and environmental benefits. The key advantages include reduced topside weight, lower power consumption, and less complex installation. The cable is also repairable and enables real-time monitoring via optical fiber,” said Andries Ferla, DeepOcean’s Technology Director and project owner.The system can be deployed after pipeline installation and is suitable for tiebacks of up to 30 km, potentially extending to 50 km, and water depths reaching 3,000 meters. It allows heating installation using smaller

Exail to Supply Next-Gen Navigation System for Deep Sea Exploration Firm
will deploy Exail’s Rovins 9-DVL navigation system and Gaps M7 acoustic positioning system, enabling operations at depths of up to 6,000 meters.The Rovins 9-DVL will be integrated into DOS’ XL Mariner work-class remotely operated vehicle (ROV), built by Argus in Norway.Combining Exail’s fiber-optic gyroscope technology with Nortek’s DVL (Doppler Velocity Log), Rovins 9-DVL ensures accurate seabed-relative navigation in GNSS-denied environments. By reducing drift and maintaining precise velocity tracking, it enhances the efficiency and predictability of subsea operations.The Gaps
Pioneer Consulting Completes Submarine Cable Marine Route Surveys in Alaska
Pioneer Consulting, a full-service submarine fiber optic telecommunications consulting and project management company, announced the completion of the marine route surveys for the “Fiber Internet Serving Homes” projects, which consist of the FISH West and FISH South submarine cable systems in Alaska. Contracted by Cordova Telecom Cooperative, Inc., a member-owned telecommunications cooperative, the survey was completed in cooperation with Benthic GeoScience.Pioneer Consulting supervised the survey and provided a representative on board the main survey vessel. Survey activities included:Inves
TenneT Hires Asso.subsea for Cabling Work off Germany
Germany, and mark the beginning of a new collaboration with Jan De Nul, acting as the main contractor, with TenneT as the end client.Each project involves the transportation and nearshore installation of a complex cable bundle comprising 2 x HVDC power cables, one metallic return cable, and one fiber optic cable.Installation will be executed in 2027 (BalWin4), 2028 (LanWin1), and 2029 (LanWin5) respectively.The scope of work includes cable transpooling from load-out ports in the Netherlands or Germany, nearshore installation operations using the cable laying vessel (CLV) Atalanti, which will be
Nokia to Power Medusa Submarine Cable System Between Europe and North Africa
Nokia announced that it will power the Medusa Submarine Cable System, a project owned by AFR-IX Telecom. The new subsea fiber-optic network will connect the Atlantic coast, Mediterranean Sea and the Red Sea, creating a new high-capacity digital corridor in the region, driving connectivity, innovation, and economic growth across the region.The Medusa subsea cable is a significant step toward closing the digital divide between Europe and North Africa, connecting countries such as Morocco, Tunisia, Libya, Algeria, and Egypt with high-capacity fiber-optic links. Designed as an open-access system
