Powering the Deepest Frontiers: Choosing Lithium Batteries for Extreme Subsea Vehicles
, embedded Battery Management System with individual cell monitoring, redundant temperature sensing, and intelligent fault protection.Solid-state relays provide rapid, arc-free disconnection in abnormal conditions, including high-voltage configurations. Internal fire-propagation barriers, water-detection systems, controlled exhaust pathways, and pressure-tolerant construction further elevate safety margins. These designs are validated through environmental testing and are certified to DNV rules for Electrical Energy Storage Systems, a critical benchmark for deep-sea and manned operations.Proven at
New Year, New Gear: Threats, Modularity, and Agility to Drive Subsea Defense in 2026
Black Sea Fleet, the strike exposed the vulnerability of well-protected, high-value harbors to uncrewed systems, and highlighted the ongoing convergence of mines, torpedoes, and UUVs. As a result, 2026 may see heightened interest in port and harbor security, including underwater barriers, intrusion detection systems, and non-kinetic counter-UUV systems, such as the Stingray net system from Annapolis-based Oceanetics.Critical Underwater Infrastructure DefenseRecent subsea incidents continue to underscore the vulnerability of critical underwater infrastructure (CUI) and the growing need for systematic protection
US pushes Fisheries Tech at APEC Amid China Rivalry
can’t be ignored across the Pacific,” Perry told Reuters, noting reports that suggest an unusual level of state coordination among its actions.Perry said U.S. companies were developing technologies including satellite vessel tracking, artificial intelligence-based analytics, acoustic detection systems and sensor-equipped ocean buoys to help governments monitor fishing activity.Illegal fishing is frequently linked to other transnational crimes including forced labour, trafficking and smuggling, Perry said.Perry noted that China's revised Fisheries Law is due to take effect from May. &ldquo
NOAA Invests $95M in Mid-Life Vessel Renovation
a new standard for energy-efficient research vessels.Commissioned in 2005, the Oscar Dyson plays a vital role in fisheries surveys and ecosystem assessments in Alaskan waters. The upcoming upgrades will include advanced, Tier 4 variable-speed generators, quiet air conditioning motors, improved fire detection systems, new pumps, fans, cranes, and radars, as well as additional single-occupancy staterooms, all designed to enhance operational efficiency, scientific capabilities, and crew comfort.To ensure uninterrupted data collection during Oscar Dyson’s yearlong maintenance period, NOAA is modifying
Kongsberg Discovery Announces Passive Acoustic Technology
happening below the waves, delivering compelling benefits for diverse user groups, explained Martin Wien Fjell, President Kongsberg Discovery.The passive acoustic solutions are as flexible as they are effective. For example, the sensors can be easily installed on subsea structures as permanent leak detection systems, or on equipment such as subsea pumps and compression systems, continuously analyzing performance to inform maintenance and operational decisions. Used as scalable array configurations, on ROVs or other mobile assets, the solutions can monitor and inspect installations, or be utilized for monitoring
Wavefront, MARSS, Forcys Showcase Multi-Domain Threat Detection Systems
Wavefront Systems, MARSS and Forcys have concluded a week-long demonstration of underwater and multi-domain security systems, hosted at Portland Port, in Dorset, UK. The event gave defense and commercial maritime stakeholders a rare opportunity to witness integrated detection systems responding to live staged threats across air, surface and sub-surface domains.Running June 10-13, each day culminated in a stealth insertion scenario, with a high-speed insertion craft deploying a dive team in an attempt to breach port security—supported by an airborne drone, simulating a simultaneous incursion.

areas ranging from renewable energy and infrastructure, through to search and rescue, all of whom rely on high resolution sonar systems and acoustic technology to unlock in-depth ocean understanding.Mesotech, which employs 50 local experts manufacturing more than 100 marine surveillance and detection systems, has been a part of the Norway-headquartered Kongsberg Group since 1997.Kongsberg Discovery launched as a standalone company last year, drawing together the Kongsberg Group’s advanced underwater robotics and sensor portfolio in a separate entity for the first time.“This is a new
Aker BP Hires Contractor for New Oil Spill Detection Solution
involved,” said Håvard Odden, director of Vissim’s North Sea operations. The system also capitalizes on machine learning to classify detected phenomena, thus preventing that the system generates false alarms which has traditionally been a concern in radar-based oil spill detection systems.The two-in-one solution from Vissim allows both vessel tracking and oil spill detection through the same radar. A higher degree of sensitivity in image processing makes the new system less susceptible to false alarms caused by heavy rain, vessel wake and other phenomena.Last autumn, Aker BP
New Sensors Expected to Reduce Illegal Immigration Across English Channel
French and British authorities have ordered infrared panoramic detection systems from French company HGH to help reduce illegal immigration across the English Channel.The two countries have previously signed a “smart border” agreement worth 72.2 million euros for the period 2022-2023. The aim is to use advanced technologies to secure the coastline and prevent people drowning onboard makeshift boats.HGH will provide its SPYNEL solutions which allow for permanent and continuous surveillance. They will be used in addition to the surveillance provided by patrols, drones and planes already used
