UK Firm Installs Floating OTEC Prototype in Atlantic Ocean
niche technology to a powerful resource. We now have a new class of standardized and replicable baseload power on a learning curve akin to wind, solar, and batteries,” said Dan Grech, Founder and CEO of Global OTEC.The prototype forms part of a $4.1 million (€3.5 million) project funded by the European Union’s Horizon Europe programme and led by Global OTEC.The company said offshore validation is now underway, with plans to deploy an OTEC Power Module in Hawaii as part of further development efforts.Global OTEC claims the technology could provide continuous baseload power for tropical island
Maersk’s Stillstrom Unveils Standalone Offshore Charging Solutions for Vessels
Stillstrom, a unit of A.P. Moller - Maersk, has launched two offshore charging systems aimed at supporting vessel electrification in the offshore wind sector.The new solutions, Power Hub and Power Tower, are designed as standalone systems that can be deployed independently of wind turbine infrastructure, enabling flexible charging options for vessels operating at sea.The systems are based on monopile designs and target one of the key challenges in offshore wind operations - the reliable supply of electric power for service vessels used in installation, maintenance and long-term operations.Stillstrom

Nor do we employ aggressive rhetoric in this regard," the embassy said in a statement.Moscow has previously denied allegations of involvement in a series of incidents in which European countries' cables were damaged.Britain Sent Warship and Patrol AircraftHealey said the Russian operation involved a Russian Akula-class attack submarine and two specialist submarines from Moscow's Main Directorate for Deep-Sea Research (GUGI)."They are designed to survey underwater
European Consortium Targets Marine Noise from Offshore Wind Projects
A group of European offshore wind and marine engineering companies has launched a consortium to develop technology aimed at reducing underwater noise from offshore construction.The Searénité consortium brings together Chantiers de l’Atlantique, EDF power solutions, Heerema Marine Contractors, Menck, RTE, Sealence and Smulders.The group aims to develop a noise mitigation system tailored to offshore wind installations, where activities such as piling and vessel operations can affect marine ecosystems.The project will focus on adapting SubSea Quieter, a patented technology developed
Nexans Completes Record-Depth Subsea Cable Project in Norway
Nexans and Statnett have completed a 420 kV subsea cable project across the Fensfjord in western Norway, strengthening power supply to Bergen and surrounding industrial areas.The project, awarded in 2022, included the engineering, manufacturing and installation of two high-voltage HVAC subsea cables spanning about 7.8 km between Haugsvær and Lindås, linking the Mongstad area to Iledalsvågen.The new connection doubles transmission capacity across the fjord and forms part of broader efforts to reinforce Norway’s high-voltage grid as energy demand rises.Nexans said the project
Jan De Nul Launches Second Giant Cable Laying Vessel
being developed to connect offshore wind farms and strengthen interconnections between North Sea countries.The new vessels incorporate hybrid power systems with a 2.5 MWh battery and engines capable of running on biofuel and green methanol, alongside emission-reduction technology designed to meet strict European standards.The company is also expanding its subsea fleet with additional vessels for cable protection, including trenching support and rock installation units, as it positions for increased demand in offshore renewable infrastructure
Decom Engineering Secures US Patent for Subsea Cutting Tech
Aberdeen-based subsea technology specialist Decom Engineering has secured a United States patent covering key elements of its Chopsaw cutting technology, strengthening its position in the subsea and onshore cutting market.The patent protects a combination of mechanical and operational features, including a linear drive cutting system, modular drive arrangement and adaptable clamping methodology, the company said.Decom Engineering said its system differs from traditional cutting tools by using a controlled linear motion to guide the blade through materials, improving precision, control and consistency
