KIMM Cracks the Code for Underwater Radiated Noise Prediction
Researchers in South Korea at the Korea Institute of Machinery and Materials (KIMM) have reportedly developed a hull-attached sensor-based system for predicting underwater radiated noise (URN), a key factor in naval stealth operations.KIMM Develops First Hull-Attached Sensor System for Predicting Underwater Radiated NoiseNew algorithm predicts underwater noise in real timeBoosts naval stealth and operational efficiencyThe new technology allows real-time monitoring of underwater noise levels generated by naval vessels, enabling early detection of abnormal vibrations and improving operational efficiency
MacArtney to Equip N-Sea’s Altera CLV Newbuild
."By joining forces with SCA and Enersea, we’ve brought together the best of three worlds—innovative technology, smart engineering, and robust execution,” said Mike Welling, Business Development Manager at MacArtney Offshore Wind Solutions. Altera CLV is being built by Neptune Marine and will transfer to The Netherlands in Q4 2025 for fitting and commissioning in Q2 2026. The DP2 vessel will be dual fuel (methanol) prepared, equipped with a 25t offshore knuckle boom crane, mooring system and can accommodate up to 99 people
Sea.AI Technology Supports European Initiative to Protect Whales
In the continuing effort to protect whales from deadly ship strikes, Sea.AI is collaborating with the Irish Whale and Dolphin Group (IWDG) and the University of La Laguna (ULL) to support efforts under the European Union’s ATLANTIC WHALE DEAL project.Whales face increasing threats from ship collisions in busy maritime routes. The ATLANTIC WHALE DEAL brings together scientists, conservationists and technology experts from across Europe to tackle the problem.Sea.AI will provide its AI-powered machine vision technology which detects and classifies objects on the water’s surface. This technology
Kongsberg Discovery Launches FS80 Trawl Sonar
Trawl Sonar.The compact, modular and multifrequency solution is the market’s first sonar system to combine net monitoring, intake profiling and bottom detection in a single unit, making the very latest sonar technology accessible to fishery operators, big and small. Originally unveiled at Pacific Marine Expo (PME) in November last year, the innovation has now been put through its paces in extensive sea trails, with first class results.The FS80 builds on the legacy of the enduringly popular FS70, which has been a trusted market leader for the past 20 years. Alongside the upgrade in performance and
ECOsubsea: Closed-Loop Hull Cleaning Is a Regulatory Imperative
consumption to environmental degradation and potential regulatory penalties – there remains a significant regulatory gap. Unlike ballast water, which is now subject to international regulations, hull biofouling remains underregulated despite profound implications for both vessel performance and marine ecosystems.In-water hull cleaning introduces additional pollution risks. Many antifouling coatings work by leaching heavy metal-based toxins to deter biofouling growth. These products are typically polymer based and a large source of micro-plastic pollution into the ocean over time. It is estimated
FLANQ Debuts USV for Maritime Surveillance, Special Forces Ops
FLANQ, a German-based maritime defense solutions provider, launched Q-RECON, a European designed and built uncrewed surface vessel (USV) for operations in the littoral domain.Developed in response to an urgent operational requirement from a European customer, Q-RECON is a lightweight, two-meter long, two-man portable USV purpose-built for intelligence, surveillance, reconnaissance, and tactical interdiction.A 30 kg internal payload bay supports a range of sensors, including 360°-night vision and multi-spectral cameras, ideal for covert monitoring, infrastructure inspections and beach landing

ice and open water, as well as myriad combinations of these conditions,” according to Cornell University professor Christopher W. Clark. “All Arctic whales, even adult bowheads, can get trapped or die in ice, so there is clearly a selective advantage for specialized attributes that enable marine mammal to sense such threats. A naturally occurring ocean soundscape is essential for these mammals to take full advantage of their adaptations for listening to and producing sounds.”The Arctic Council’s Protection of the Arctic Marine Environment Working Group (PAME) has been studying

As naval demand for Saildrone services grows exponentially, John will deliver the leadership firepower I need to grow both the team
NOC: Natural Disasters Responsible for 25% of Subsea Cable Damage
underpinning global connectivity.While human activities like fishing and anchoring remain the primary causes of damage, the study warns that climate change is intensifying many natural hazards, increasing risks to these vital networks.The threats from natural hazards range from earthquakes and submarine landslides to powerful underwater currents triggered by river floods.“These events can damage cables, bury them under sediment, or render them inoperable,” said Dr. Isobel Yeo, a researcher at NOC and co-lead on the project. “With climate change driving more extreme weather, rising
