Space Norway, SubCom Announce Contract-in-Force for Arctic Way Cable System
, NH, USA. The trunk-and-branch, repeatered system will be approximately 2,350 km in length with direct shore end landings in Bodø, Norway, Jan Mayen, andLongyearbyen, Svalbard. Located entirely within the Arctic Circle (between 67-78°N), the system will be the world’s northernmost subsea cable system and will be installed by one of SubCom’s polar-certified, Reliance Class cable ships.“Establishing the new Arctic Way cable system is imperative to ensure that data connectivity for the Arctic community is effective and uninterrupted for decades to come,” said Morten
UK Researchers Tackle Landslide Risks for Offshore Wind Turbines with New Tool
Researchers at Heriot-Watt University have developed an advanced simulation tool that accurately predicts underwater landslides caused by offshore wind turbines.The new method enables developers to assess seabed stability not only at the design stage but throughout a wind farm’s lifespan, helping to optimize placement and ensure long-term resilience.Underwater landslides - when sections of the seabed suddenly shift - can impact the stability of wind turbines, particularly in areas with soft seabeds and gentle slopes.While engineering structures like monopiles (the foundations of some offshore
Belgian Energy Island in North Sea Starts Taking Shape (Video)
TM Edison, a consortium of Belgian marine construction companies DEME and Jan De Nul, has installed the first two of a total 23 caissons in the Belgian North Sea, marking the start of construction for the Princess Elisabeth Island, the ‘world’s first’ artificial energy island.Caissons are concrete building blocks that form the outline of the future island. In a later phase, the interior will be filled with sand to build high-voltage infrastructure that will connect new offshore wind farms.TM Edison is carrying out the work on behalf of grid operator Elia Transmission Belgium (Elia).

CRP Subsea to Supply Well Equipment for Shell’s Whale Development
CRP Subsea, an AIS company, has secured a contract with Shell for the supply of crushable foam wrap (CFW) for the Whale deepwater development in the Gulf of America.The initial order is for one well-set, with additional orders for four more well-sets expected throughout 2025. Each well-set comprises 1,798 CFW quadrants, each one meter in length.The package also includes installation equipment, such as adhesive (one tube per two quadrants), adhesive dispensing guns, tie wraps, and Spanset straps. CFW is an engineered syntactic foam, comprised of a thermoset resin and hollow glass microspheres (HGMS).
Nexans to Deliver Subsea Cables for Second Malta-Sicily Interconnector
Nexans has secured a contract by Interconnect Malta (ICM) to deliver high-voltage subsea cable for Malta’s second interconnector.The new high-voltage alternating current (HVAC) link will reinforce Malta’s electricity system, ensuring a stable and resilient energy supply.The cables for this project will be produced at Nexans’ facility in Charleston, United States.The 225 MW interconnector will operate at 220 kV and consists of subsea cable linking Maghtab, Malta, and Ragusa, Sicily. It will be installed in parallel with the existing interconnector, previously delivered by Nexans in
Van Oord Expands its Trencher Fleet
system which uses high-pressure water to fluidize the substrate and create a trench.“Each trencher in our fleet has its own strengths, allowing us to tailor our approach to soil conditions, trench depth, and project requirements. With the arrival of Jet-It, we can offer even greater efficiency in subsea cable installation,” Vann Oord said on social media.It is said to be ideally suited for the burial of inter-array and export cables in sandy and light clay soils.With two high-pressure, frequency-driven water pumps, it is capable of trenching to depths of up to 3 meters. Multiple integrated
