Gennaker Offshore Substations Depart for Baltic Sea Installation (Video)
The topsides and jackets for two offshore substations serving Germany's 927 MW Gennaker offshore wind farm have departed the Netherlands for installation in the Baltic Sea as part of the OST-6-1 offshore grid connection project.The OSS Zingst and OSS Darß substations are being delivered by the HSI joint venture, comprising Smulders HSM and Iv, under an engineering, procurement, construction, installation and commissioning (EPCIC) contract.The substations, each with a capacity of approximately 450 MW, will form part of the infrastructure connecting Skyborn Renewables' Gennaker offshore
TenneT Joins Subsea Cable Decommissioning Tool Development
TenneT Germany has joined DEME and Subsea Cable Assets (SCA) as a development sponsor of Frequensea's subsea cable decommissioning tool, which is being developed to recover buried offshore cables while reducing seabed disturbance.The technology uses patented vibration-induced fluidisation to reduce soil resistance around buried subsea infrastructure, allowing cables, umbilicals and pipelines to be recovered with potentially smaller vessels and lower energy consumption.TenneT Germany will contribute its experience as an offshore transmission system operator, particularly in subsea power cable
DNV Certifies Buchan Floating Offshore Wind Foundation Design
Buchan Offshore Wind has secured DNV Basic Design Certification for the BW Ideol-designed concrete Damping Pool floating foundation planned for its nearly 1 GW project off Scotland, marking a further engineering milestone ahead of commercial-scale development.The certification provides independent validation of the project-specific foundation design selected for Buchan, which is being developed around 75 km northeast of Fraserburgh in the North Sea.“Achieving DNV Basic Design Certification is a significant milestone for the Buchan project, reflecting the expertise, commitment and hard work of
Verlume Clears Key Test for Offshore Wind Subsea Battery
Verlume has completed hyperbaric testing of the enclosure for its Orah subsea energy storage system, clearing a qualification milestone ahead of its planned deployment at the OranjeWind offshore wind farm in the Dutch North Sea.The testing was carried out at JFD's hyperbaric facility in Aberdeen and subjected the enclosure to a controlled pressure profile representative of its intended subsea operating environment.The 10-tonne enclosure, measuring 7.2 meters long, 2.4 meters wide and 2.4 meters high, was the largest vessel tested at JFD's hyperbaric center to date.Testing covered pressure and
Chevron Joins SLB, TotalEnergies Digital Subsurface Collaboration
Chevron Technical Center has joined a long-term digital subsurface collaboration between SLB and TotalEnergies to co-develop technologies for reservoir engineering and geoscience.The collaboration, known as Arena, was established by SLB and TotalEnergies in 2024 and will now include Chevron as its second global operator.Chevron will contribute investment, intellectual property and technical expertise, including capabilities in uncertainty analysis, optimization and field development planning, to help shape the development of scalable digital subsurface technologies.Arena is focused on technologies
Orcadian Terminates UK Offshore Data Center Development Deal
Orcadian Energy and an unnamed U.S. offshore data center developer have terminated an agreement to jointly develop an offshore energy-to-compute project using gas resources from Orcadian's Earlham and Orwell discoveries in UK waters.The companies ended the agreement because the development scope and timeline for Earlham did not align with the U.S. developer's near-term deployment priorities, Orcadian said.The Earlham Gigagrid concept envisages using gas resources within Orcadian's P2680 license to provide power and infrastructure for offshore computing capacity, disconnected from the UK
ACUA, Forssea Complete Remote ROV-USV Trials
and light intervention operations off Plymouth in the UK.The three-week campaign paired Forssea's 170-kg ARGOS ROV with ACUA's USV Pioneer, completing more than 40 deployments with launches, dives and recoveries commanded remotely from shore.The integration, carried out under a contract with the European Space Agency, included operations in two-meter waves south of the Plymouth breakwater, with no impact on the ROV, according to the companies.Over six days at sea, the partners completed as many as eight launch-and-recovery cycles in a single day. The ROV reached and inspected the seabed in more
Shearwater Lines Up Three-Year South America OBN Campaign
Shearwater Geoservices has been awarded a three-year ocean bottom node (OBN) seismic acquisition contract by an undisclosed oil and gas company for work offshore South America, with operations set to begin in the fourth quarter of 2026.The contract includes firm scopes in the first and third years of the award period, as well as a framework for potential additional projects during the three-year term.Shearwater will deploy the SW Tasman using its internally developed Pearl node technology, while the SW Gallien will carry out source operations.Both vessels are expected to work on the campaign through
Omega Subsea to Deploy ROVs on NKT’s Cable Laying Vessels
announced in June for NKT Victoria, with mobilization activities for the two vessels now underway at shipyards in Ulsteinvik and Brattvåg.Eleonora, due to enter service in 2027, will have capacity to carry more than 23,000 tonnes of cable and will work on high-voltage power cable projects across Europe. The Salt Ship Design vessel is being built and outfitted by Vard for NKT.“NKT is one of the leading players in the cable installation industry, and being selected to support two of their modern cable-laying vessels is a strong vote of confidence. We are expanding both our equipment base and
