JDR Wraps Up Type Test Qualification of Next-Gen Offshore Wind Cables
JDR Cable Systems (JDR), part of the TFKable Group, has completed two new type test qualifications at 132kV for static and dynamic array cables, supporting the next generation of fixed and floating offshore wind projects.The successful testing marks a critical step in delivering U.K.-manufactured high-voltage cables, ready to support larger turbines and deliver power over longer distances, enabling more efficient and cost-effective offshore wind energy.JDR’s static cable development and testing was supported by a Development Grant from the Offshore Wind Growth Partnership, and produced in
Upscaling Power Subsea: Cables and Connectors
offshore wind power to shore are already so massive that one meter of cable can weigh 300kg. Nexans had previously upscaled its production facilities to cater for increasing demand; now it is upscaling its HVDC cables, typically 400kV, to 525kV. The company will be supplying at least 10 of these cable systems to European grid operator TenneT for multiple 2GW projects.The cables will be heavier, and they have the potential to get hotter, necessitating deeper burial in the seabed. The potential risks can be a determining factor in the design of the cable. If a live cable were to be damaged, says Pascal
SubCom Deploys One Million Kilometers of Subsea Cable Systems Globally
SubCom recognized a historic organizational milestone: the deployment of more than one million kilometers of subsea cable. At a ceremony held at SubCom’s campus in Newington, CEO David Coughlan accepted a special commendation from the State of New Hampshire by Governor Kelly A. Ayotte in celebration of the company’s industry-first achievement.SubCom, whose origins date back to the mid-1800s, has been a global leader in subsea cable design, manufacturing, and deployment since its entry into the communications industry in 1955. INearly all of the world’s data is transmitted via secure
Space Norway, SubCom Announce Contract-in-Force for Arctic Way Cable System
decades to come,” said Morten Tengs, CEO of Space Norway.“While establishing new subsea cable infrastructure, we will continue to utilize the two existing cables to Svalbard as long as they remain functional, serving as a backup for Arctic Way," said Rune Jensen, Director of Subsea Cable Systems at Space Norway. "Although these cables are approaching the end of their 25-year service lifespan, we expect them to remain operational for several years past 2028.” The Arctic Way Cable System is expected to be ready for service by Q2 2028
Belgian and Greek Contractors Reel In UK’s HVDC Interconnections Deal
Cables has signed a framework agreement with National Grid for strategic HVDC interconnections in the U.K.This agreement will entitle the consortium to participate in upcoming tenders for call-off projects for the design, manufacturing, supply, installation, testing, and commissioning of HVDC cable systems as part of National Grid’s large-scale offshore and onshore transmission infrastructure investment program.The deal, which has an initial term of five years with an option for extension of up to three additional years, is a key component of National Grid’s strategy to secure long-term
Tadek Ocean Engineering expands UK office
Tadek Ocean Engineering is celebrating 15 years in business with an expansion into new UK offices and a landmark 300 projects. Tadek specialises in the delivery of pioneering cable systems, risk advisory and analysis work to developers and owners of fixed and floating assets across marine, offshore and subsea sectors. They also focus on grassroots work in installation analysis and project engineering and management.They are also rapidly enhancing expertise in offshore renewables, including pre-FEED optioneering studies to FOW (Floating Offshore Wind) developers plus MRE (Marine Renewable Energy)
Turbidity Currents and Their Effects on Subsea Fibre Optic Cables
by human activity or intrinsic failure of the cable’s systems, this leaves 118 faults since 1965 after apportioning unknowns based on the known fault causes. This equates to two faults per year, although they are more common in our database in recent years due to both the increasing number of cable systems and improved recording of faults.Since January 2020, 37 faults have been recorded within submarine canyons, of which 24 (65%) are thought to have been due to natural processes. By comparison, faults originating from all natural causes over the same time period made up less than 18% of the global
Siemens Hires Pfisterer for DolWin4 and BorWin4 Grid Connection Cable Package
Germany-based electrical connection technology supplier Pfisterer has secured a contract from Siemens Energy to provide turnkey cable systems for the BorWin4 and DolWin4 offshore grid connections.The two platforms will enable the transmission of offshore wind energy to the German mainland, making a significant contribution to a renewable energy supply.Pfisterer is in charge of implementing the entire 66 kV AC cable infrastructure between the gas insulated switchgear (GIS), transformer and submarine cable connection on the DolWin4 and BorWin4 platforms.This involves planning, comprehensive engineering
Space Norway Launches World's Northernmost Subsea Cable

Although these cables are approaching the end of their 25-year service lifespan, we expect them to remain operational for several years past 2028," said Rune Jensen, Director of Subsea Cable Systems at Space Norway.The trunk-and-branch, repeatered subsea cable system will have direct shore end landings in Bodø, Norway, Jan Mayen and Longyearbyen, Svalbard. The 2,350-kilometer cable will be situated entirely within the Arctic Circle, between 67-78°N
