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

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
the two existing cables to Svalbard as long as they remain functional, serving as a backup for Arctic Way. 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
Global Underwater Hub Forms Taskforce to Improve Subsea Cable Reliability and Performance
a white paper on its approach to tackling a crucial issue that could derail the UK’s clean energy ambitions. The trade and development body, representing the UK’s £ 9.2 billion underwater industry, has set out how it aims to improve the performance and reliability of subsea cable systems, critical elements of offshore wind infrastructure essential to transmitting electricity from offshore wind farms to the grid.Globally, over $ 800 billion of investment in offshore wind farms is anticipated by 2030, and for the world to hit net-zero emissions by 2050, the generating capacity
TenneT Hires Nexans for LanWin 2 Export Cables Scope
for LanWin 2, valued over $1 billion, under the TenneT frame agreement awarded in May 2023.The project involves the Engineering, Procurement, Construction, and Installation (EPCI) of 250 km of 525 kV High-Voltage Direct Current, Cross-Linked Polyethylene (HVDC, XLPE) onshore and offshore export cable systems.The project is part of the development of TenneT’s 2 GW offshore grid connection program in the German North Sea. Commissioning of the project is expected in 2030.It further sterngthens Nexans’s ongoing partnership with TenneT, following the BalWin3 and LanWin4 projects announced
NKT Secures Two High-Voltage Cable Projects for TenneT’s 2GW Program
The Dutch-German transmission system operator (TSO) TenneT has selected Danish subsea cable and services firm NKT to provide onshore and offshore high-voltage cable systems for two projects in Germany as part of its 2 GW grid infrastructure program.Under the existing multi-year framework agreement with TenneT. NKT will provide 525 kV XLPE high-voltage direct current (HVDC) onshore and offshore power cable systems for two projects – LanWin7 and NordOstLink.The contracts are expected to be called off in 2026-27 and will have a combined value of approximately $1.03 billion, which includes cable
