Subsea Warfare Need Not Involve Target Destruction
of Ukraine in 2022, including sabotage of the Nord Stream gas pipelines.As defense analyst David R. Strachan points out in the May/June issue of Marine Technology Reporter: “Seabed warfare will increasingly be defined by the need to contest a dense battlespace teeming with sensor networks, communications nodes, autonomous vehicle hubs and energy systems, with a range of commercial, scientific and military assets, potentially finding themselves on a subsea strike target list.”Strachan explains the potential targets, and the weapons, and points out that a subsea strike would not require a
Blue Logic and Hydromea to Accelerate Subsea WLAN Deployments
Hydromea, a leader in high-speed wireless subsea optical communication, and Blue Logic, a pioneer in underwater inductive power and data transfer, have announced a strategic partnership they say will revolutionize wireless subsea communications.They aim to enable enabling humans in the loop remotely piloting an underwater drone without an umbilical.The collaboration integrates Blue Logic’s advanced inductive technology with Hydromea’s free-space optical (FSO) solutions, enabling unprecedented speed, reliability and flexibility in subsea WLAN deployments for critical data offloads and
CCG's New Offshore Oceanographic Science Vessel Begins Sea Trials
on the West Coast by specialists from Seaspan, the Canadian Coast Guard and major equipment suppliers to test performance of key systems and seaworthiness. The tests ensure that the ship operates as designed and that all systems—including mechanical, electrical, hydraulics, scientific, communications, navigation, as well as fire and safety systems—are fully operational.On completion of sea trials, CCGS Naalak Nappaaluk will be prepared for delivery to the Canadian Coast Guard by the end of the summer, before sailing to the Bedford Institute of Oceanography in Halifax, NS, where the
Upscaling Power Subsea: Cables and Connectors
Cable and connector manufacturers are rushing to meet the growing demand for subsea cables and connectors as renewables upscale, but whether it’s renewables or oil and gas, there’s also growing demand for high-tech subsea communications.The export cables that bring offshore wind power to shore are already so massive that one meter of cable can weigh 300kg. Nexans had previously upscaled its production facilities to cater for increasing demand; now it is upscaling its HVDC cables, typically 400kV, to 525kV. The company will be supplying at least 10 of these cable systems to European grid
Deep Strike: Seabed Warfare Will Target More Than Cables and Pipelines
rugged terrain. Except the craft aren’t stealth bombers—they’re BWBUGs. And the terrain isn’t rolling countryside—it’s the ocean floor.Discussions of seabed warfare are usually centered around attacks on critical underwater infrastructure (CUI)—power and telecommunications cables, oil and gas pipelines. But while these nodes in the global information and energy grids are indeed critical, they represent just one target set within a rapidly evolving undersea domain. Seabed warfare will increasingly be defined by the need to contest a dense battlespace teeming with
Mother Ship with USV Flotilla Could Boost Coast Guard Capabilities
could be a mother ship suitable and seaworthy for the purpose intended. For instance, for the Labrador Sea, the mother ship could be based on a 45-50m offshore tug or standby emergency response vessel. The ship layout could include rescue facilities, towing capability, winches, a flotilla communications hub, and fuel and stores capacity for 60 days of operation.The intent is for the mother ship to sail with a small crew (say 10 to 20) and work on a lay day system – such as month on month off. It could be small enough to work from a northern Arctic base but able to return to a southern
Trapped Wave Mystery Solved
, even for periods which the satellite did not observe. The researchers also reconstructed weather and tidal conditions to confirm that the observations could not have been caused by winds or tides.The study ‘Observations of the seiche that shook the world’ has been published in Nature Communications
Sonardyne to Deliver Seabed Monitoring Kit for North Sea CCS Project
of the site will begin in the summer of 2026 to provide baseline data for a duration of two years before the transportation and storage of captured CO2 starts.The seabed landers will be equipped with Sonardyne’s Edge data processing application, power management and acoustic through-water communications to enable long-term, remote battery-operated deployment.Each lander will also contain a suite of hardware including Sonardyne’s Origin 600 ADCP, Wavefront’s passive sonar array and multiple third-party sensors. Together, this technology can detect small changes in water chemistry
Fincantieri Presents Underwater Segment, Revenue Expected to Reach 920 Million in 2027
at around USD$741 million and USD$808 million (660 million and 720 million euros) and EBITDA margins of 17.4% and 18.0%, well above the Group’s traditional shipbuilding activities.Today, the underwater domain is a strategic area for security, energy, environmental monitoring, and underwater communications. Fincantieri aims to be a leading player in the development of this new strategic infrastructure, leveraging its ability to integrate complex capabilities and high-tech industrial assets. To oversee this transformation with consistency and vision, the Group has established the Underwater Technology
