NextGeo Scoops $27.8M for North Sea Offshore Wind Surveys
Marine geosciences and offshore construction support services firm Next Geosolutions has been hired by TenneT under a $27.8 million contract to conduct an unexploded ordnances (UXO) survey off the Dutch coast, in support of the development of offshore wind farms.This contract involves the execution of marine UXO survey, to identify and locate magnetic anomalies potentially associated with unexploded ordnance, which may represent obstacles to the installation of new offshore infrastructure, in the Doordewind offshore wind area.Additionally, the contract includes an UXO survey in the Nederwiek offshore
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
UK Approves Five Subsea Power Cable Projects
at Ofgem said in a statement.Ofgem also approved Britain's first offshore hybrid assets (OHAs), which can directly feed energy generated by offshore wind farms into both British and European grids, and are both planned by National Grid.The LionLink project, co-owned by Dutch grid operator Tennet, will connect Dutch offshore wind farms to both the Dutch and the British grids and provide up to 1.8 GW of low-carbon electricity to each country.In the same way, the Nautilus project, co-owned with Belgian grid operator Elia, will connect Belgian offshore wind and provide up to 1.4 GW of capacity
Installation of Hollandse Kust (west Beta) Export Cables in Full Swing
suction hopper dredger Gateway.Boskalis is in charge of the Hollandse Kust West Beta wind farm export cable installation in consortium with consortium with Orient Cables (NBO).Following the installation of the export cables, Boskalis will install a 9-kilometer-long 66kV interconnector cable between the TenneT projects Hollandse Kust (west Alpha) and Hollandse Kust (west Beta) offshore connector platforms, the company said earlier.The 700 MW Hollandse Kust West Beta offshore wind farm is expected to enter service in 2025.In May, Heerema Marine Contractors installed the jacket for the Hollandse Kust (west
Nexans Opens Newly Expanded Subsea Cable Facility in Norway
most advanced cable production technology to date and features a second 152.89-meter-tall extrusion tower which will allow the plant to insulate four cables simultaneously in addition to the two existing lines.The expansion project will support key projects including Nexans’ frame agreement with TenneT signed last year.The construction for the expansion of the plant began in November 2021 and incorporates some of the most advanced cable production technology which will be able to deliver subsea cables up to 525kV for High Voltage Direct Current (HVDC) and 420kV for High Voltage Alternating Current
First Cable Production for 2GW North Sea Offshore Wind Grid Link Kicks Off
of new cables with a voltage of 525 kV, intended for the BalWin4 and LanWin1 offshore wind grid connection projects, has started at LS Cable’s facilities in South Korea.The start of production at LS Cable in South Korea’s Donghae marks the beginning of a new technological chapter for TenneT's offshore grid connection systems.The new cables with a voltage of 525 kV raise the transmission capacity for offshore wind energy to a new voltage level.They make it possible to transmit 2 GW of direct current over long distances with low losses. Up to now, 320 kV cables have been used for
Hollandse Kust West Beta Export Cables to Come Ashore Next Week
The first export cable for the Hollandse Kust West Beta offshore wind farm will come ashore next week as the work progresses to connect the 700 MW project to the Dutch grid.According to an update from transmission system operator TenneT, several ships will appear off the coast of Velsen in the coming days to facilitate the installation of two electricity export cables.Following the onshore drilling operations, the conduits for the electricity cables are already in place. The first cable will be brought from the sea to the beach from the Giant 7 installation barge next week.A 200-ton winch on the work
