From Trials to Cable Lay: SMD Quantum ROV Set for Fleeming Jenkin Integration
renewable energy transmission, the vessel has a cable carrying capacity of 28,000 tons, making it the largest cable-laying vessel in the world.Fleeming Jenkin is equipped with three cable carousels—two 11,000-ton turntables above deck and one 7,500-ton turntable below deck—along with two fiber optic tanks, enabling the vessel to bundle and lay up to five cables simultaneously, with combined carousel capacity described by Jan De Nul as double that of any other cable-laying vessel currently on the market.On the aft deck, the vessel features a cable laying chute for shallow-water operations
Underwater Infrastructure Security Project Launched in Norway
limited monitoring approaches.INSURE will address this challenge by developing a cost-effective, long-range, and continuous monitoring solution based on Distributed Acoustic Sensing (DAS), combined with advanced signal processing, machine learning, and multi-source data fusion. By transforming existing fiber-optic cables into real-time sensing systems and analyzing underwater acoustic intelligence with vessel tracking data, INSURE enables early threat detection, precise geo-localisation, and predictive risk assessment.This provides actionable, real-time decision support for first responders and maritime
The Impact of AI Traffic on Subsea Fiber Networks
Fiber optic networks provide the connectivity ubiquitous to modern society, enabling financial transactions, business critical traffic, national defense, entertainment, and personal interactions across the globe. Optical fiber extends to homes, businesses, and 5G radios in metro networks, connects cities within countries, and countries within continents. Subsea fiber cables spanning seas and oceans extend that connectivity between continents. The massive data-carrying capacity of optical fiber has led to wide deployment of subsea fiber cables. Today, over 570 in-service subsea cables carry
New Rayfin Uplink Camera Unlocks HD & 4K Imaging for Legacy ROVs
already own. The system provides a direct digital connection between the Rayfin Uplink ROV camera and a topside control unit or laptop.SubC’s Uplink technology uses the coax or twisted pair already inside many ROV tethers, giving established fleets access to modern imaging performance without fiber optic upgrades.It also includes built-in single channel DVR+ recording, with an option to upgrade to multi-channel, so operators can get more capability from the same camera.The Rayfin Uplink was developed for energy, marine science, environmental, defense, and subsea engineering teams that need higher
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
