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
US Lawmakers Tech CEOs to Address Security Concerns About Subsea Cables
companies from connecting undersea submarine communication cables to the United States that include Chinese technology or equipment.Since 2020, U.S. regulators have been instrumental in the cancellation of four cables whose backers had wanted to link the United States with Hong Kong.In November 2024, two fiber-optic undersea telecommunication cables in theBaltic Sea were cut, prompting investigations of possible sabotage. In 2023, Taiwan accused two Chinese vessels of cutting the only two cables that support internet access on the Matsu Islands. In addition, Houthi attacks in the Red Sea may have been

What is the jacket material, construction, and fillers? Is it suitable for overmolding?Is the instrument
Upscaling Power Subsea: Cables and Connectors
and HV connectors for production and processing are also under development.Demand for greater subsea connectivity is pushing the cable and connector market forward. Hardisty says big data is being utilized subsea to improve well efficiency and economic performance. This trend requires ethernet and fiber optic products. “Recently, we completed a project that involved installing a fiber optic subsea network to facilitate communication between onshore locations and multiple offshore oil and gas production units.”There is also a transition towards all-electric trees. Siemens Energy has introduced
SubCom Deploys One Million Kilometers of Subsea Cable Systems Globally
;s industry-first achievement.SubCom, whose origins date back to the mid-1800s, has been a global leader in subsea cable design, manufacturing, and deployment since its entry into the communications industry in 1955. INearly all of the world’s data is transmitted via secure, high-speed fiber optic cables that connect continents and propel the global economy. No company on the planet has deployed more cable and system components than SubCom—enough to circle the Earth more than 25 times.“On behalf of the entire team at SubCom, we are honored and grateful to have the opportunity
Quantum Sensing Beats GPS-Denied Navigational Challenges
Opal, is completely passive and undetectable and cannot be jammed or spoofed by known conventional techniques. It combines in-house-developed hardware and various software-level innovations. Key is the inclusion of a quantum magnetometer along with classical inertial navigation hardware such as a fiber-optic gyroscope. These sensors detect tiny, otherwise imperceptible signals arising from Earth’s structure that serve as magnetic “landmarks” for navigation. Only quantum sensors provide the sensitivity and stability needed to continuously “see” these landmarks from
