FreeStar Delivers Rapid Multi-Technology Cable Survey for TenneT
system operator TenneT, mobilizing multiple survey technologies aboard FreeStar’s vessel Navicula Star to inspect power cables off the Dutch coast.The project took place in February 2026 near Eemshaven and focused on sections of the COBRA interconnector cable linking the Netherlands and Denmark. TenneT commissioned FreeStar to carry out a 4K ultra-high-definition video survey to carry out a depth of cable burial survey. For this project, Seekable introduced its new electro-magnetometer-based survey system to determine cable positioning and burial depth.Operating in water depths of around

More to Consider than CO2 in CCS Leakage Risks
Researchers from the Technical University of Denmark have highlighted that taking a comprehensive view of the chemical composition of potential fluids leaking from geological CO2 storage reservoirs raises new questions about the potential risks.The study, published in the Journal of Environmental Management, says, albeit small, the risk of failures during operations and storage does exist.Different environmental modelling studies have suggested that different annual leakage rates (0.001%–0.01% of stored CO2) are acceptable for the climate mitigation benefits of carbon capture and storage (CCS).
New Study Reveals How Greenland’s Seaweed Stores Carbon in the Deep Ocean
after leaving coastal rocky shores.To address this knowledge gap, the study team, co-led by the Leibniz Institute for Baltic Sea Research Warnemünde and Helmholtz-Zentrum Hereon in Germany and involving scientists from Plymouth Marine Laboratory, University of Exeter, Portugal, Saudi Arabia and Denmark, used a combination of satellite imagery, ocean drifter tracking, numerical modelling and advanced turbulence analyses to demonstrate that extensive mats of macroalgae can travel hundreds of kilometres offshore. Eventually these mats may sink to great depths where their organic carbon may be stored
NUWC Division Newport’s AUTEC Range Performs Sensor Accuracy Test of German Ship for NATO FORACS
;s longest-running technical programs, providing standardized testing for shipboard sensors, navigation equipment and combat systems.The effort began in 1971, when NATO approved a study group to outline requirements for a multinational accuracy-checking range. Three years later, seven nations — Denmark, Germany, Greece, Italy, Norway, the U.K. and the U.S. — signed a memorandum of understanding formalizing the project, and in 1977 the NATO FORACS Office was established. The first test site opened near Stavanger, Norway, in 1978, followed by Greece’s Souda Bay range in 1984.NATO FORACS
Freire Shipyard Celebrates Keel-Laying of Dana V Research Vessel
Freire Shipyard has celebrated the keel laying of the new flagship research vessel for the Danmarks Tekniske Universitet (DTU -Technical University of Denmark). Measuring 70 meters length and 16 meters beam, with accommodation for 38 people, the Dana V is set to become a world-class platform for research and education.Successor to the Dana IV, the Dana V was designed by the Knud E. Hansen A/Sconsortium, Odense Maritime Technology A/S and Naval Architects, with environmental sustainability at its core. The vessel can operate on either biodiesel or electric batteries, switching between propulsion
Another TSO Enlists Njord Survey for Offshore Wind Support Services
Swedish firm Njord Survey has entered into a frame agreement with Energinet, Denmark’s national transmission system operator (TSO), covering site and route survey services for offshore wind and subsea cable projects.The long-term collaboration reinforces Njord Survey’s position as provider of services to the offshore renewable sector.It follows the agreement company signed earlier in October with German TSO 50Hertz to deliver geophysical and ROV seabed survey service in support of offshore wind developments in Baltic Sea.Swedish Firm to Deliver Carbon-Neutral Surveys for Baltic Sea OW
Marine Heatwaves Impact Food Webs
journal Nature Communications today, was conducted by an interdisciplinary team of researchers from MBARI, the University of Miami Rosenstiel School of Marine, Atmospheric, and Earth Science, the Hakai Institute, Xiamen University, the University of British Columbia, the University of Southern Denmark, and Fisheries and Oceans Canada.To explore the impacts of marine heatwaves on ocean food webs and carbon flows, the research team combined multiple datasets that tracked biological conditions in the water column in the Gulf of Alaska for more than a decade. This region experienced two successive
