Fugro Concludes Site Investigations for TenneT’s Offshore Grid Links
and marine site investigations for transmission system operator (TSO) TenneT Germany, to support the development of the LanWin1 and LanWin2 offshore grid connection projects.These projects are part of TenneT Germany’s 2 GW program, a major initiative that aims to connect at least 14 offshore connection systems to the onshore electricity grid, delivering clean energy to up to 35 million European households.The LanWin2 cable route required a range of onshore and nearshore investigation activities to support project development. Fugro’s new GroundIQ service enabled low-impact geophysical surveys
Baker Hughes to Supply Up to 50 Subsea Trees for Petrobras' Brazil Fields
will also be deployed in more recent pre-salt developments, including the Mero and Buzios fields, to optimize production in new wells.Under the agreement, Baker Hughes will manufacture Petrobras’ pre-salt standard subsea trees, as well as subsea distribution units, in-line tees and vertical connection systems, to enable safe, reliable and efficient production on the seafloor.In addition, topside control cabinets will provide monitoring and control of subsea equipment from floating production storage and offloading vessels.The project will start procurement and manufacturing in the third quarter
TenneT Installs Giant HVDC Offshore Wind Converter Platform in North Sea
, part of German transmission system operator (TSO) TenneT’s grid expansion project, has been installed in the North Sea.The installation of DolWin epsilon HVDC platform at DolWin cluster the German North Sea follows the recent installation of BorWin epsilon platform, forming offshore grid connection systems, which are due to be commissioned in 2025.The DolWin epsilon was built by Seatrium, while Aibel and Hitachi Energy installed the final technical equipment, including the HVDC converter and transformers, prior to commissioning.The platform is designed with a lifespan of 30 years and can convert
Strohm, UNITECH Unite for Enhanced Subsea Pipeline Solutions
Thermoplastic composite pipe (TCP) manufacturer Strohm, and provider of subsea connection systems UNITECH Offshore have signed a memorandum of understanding (MoU) to develop and commercialize an integrated system for the transportation of fluids and gases.Under the MoU, the two companies are creating a subsea, end-to-end jumper connection solution without flange which reduces the risk of leaks and simplifies the installation process.UNITECH’s connector will be integrated with Strohm’s TCP end-fitting, creating a flange-less interface.“By joining forces with UNITECH Offshore, we
NKT Secures Two High-Voltage Cable Projects for TenneT’s 2GW Program
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 design, engineering, production as well as on- and offshore installation.The LanWin7 system is one of the offshore grid connection systems planned to connect to the multi-terminal hub in the area of Pöschendorf, Schleswig-Holstein.This so-called NordHub will integrate multiple direct current (DC) and AC connections, facilitating the efficient transport of wind power from the North Sea to the onshore grid.The NordOstLink (partial)
Apollo Wraps Up Trials of Quick Connector for Floating Offshore Renewables
or moorings for floating offshore renewable energy devices.The trials, which took place from the end of March to the end of May 2024 in Orkney, demonstrated the robust capabilities of the system in real-sea conditions, according to Apollo.Developed through the Wave Energy Scotland (WES) Quick Connection Systems program and with support from the Offshore Wind Growth Partnership, the PALM QCS is designed to simplify the efficient hook-up and disconnection of cables and/or moorings for floating offshore renewables.The system is said to be able to reduce operational costs by enabling quick connections
First Cable Production for 2GW North Sea Offshore Wind Grid Link Kicks Off
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 offshore grid connections, for example
DEME Scoops ‘Most Extensive’ Cabling Contract in Its History
fleet, including cable installation vessels, hopper dredgers and a fallpipe vessel. In addition, the project will cover the beach works and cofferdam structures at the cable landing locations.The works are scheduled to begin in stages from 2025.IJmuiden Ver Alpha and Nederwiek 1 are offshore grid connection systems operated by TenneT that will link two future offshore wind farms in the Dutch North Sea to the province of Zeeland in the southwestern part of the Netherlands.The first connection will be operational in 2029, and the second in 2030.“We are proud to be working with Prysmian on this landmark
Nexans Secures First Call-Off Under TenneT’s Offshore Wind Grid Deal
and installation of the ten cable systems amounts to approximately €5.5 billion.As part of the call-off with TenneT, Nexans will be responsible for the engineering, procurement, construction and installation (EPCI) of high-voltage direct current (HVDC) cables for the BalWin3 and LanWin4 grid connection systems.The grid connection systems, each with 2 GW capacity, will be able to transmit total of 4 GW of offshore wind energy from the North Sea to Wilhelmshaven in Germany, Lower Saxony.Nexans said it will use its new 525 kV HVDC XLPE cable technology and implementing an innovative ‘four bundle&rsquo
