Allseas and Heerema bag Tennet platforms installation deal   Offshore construction specialists Allseas and Heerema Marine Contractors (HMC) have secured multi-year framework agreements with transmission grid operator TenneT to transport and install at least 14 supersized offshore wind converter stations in the Dutch and German parts of the North Sea. 🔽 Find more info in comments below 🔽 #Allseas #HeeremaMarineContractors #TenneT #NorthSea #OilandGasNews ⤵️Click Follow on our page to keep up to date with energy news⤵️

“World’s first subsea floating-wind power system goes on trial” Ashwini Sakharkar - January 4, 2024 “Subsea Collector connects multiple wind turbines electrically in a star configuration. Credit: Aker Solutions” “Norwegian energy sector service provider Aker Solutions has signed a front-end engineering and design (FEED) contract with the Marine Energy Test Centre (METCentre) in Norway to pilot new #subseapowersystemtechnology, which has the potential to significantly reduce the costs and complexity of #offshorewindfarms.” “As part of the project, Aker Solutions will provide the #SubseaCollector for METCentre’s offshore wind test area, which currently has two #floatingoffshorewindturbines located 10 kilometers off the southwestern coast of Karmøy, Norway. The test area will be expanded to seven floating offshore wind turbines starting in 2026.” “Subsea Collector is a novel approach to connect multiple #windturbines electrically in a #starconfiguration instead of the traditional #daisychainpattern, enabling more #flexibility in #offshorewindfarmarchitecture and construction. The design also allows for #reducedcablelength per turbine and park and less vessel time and installation costs. Initial findings support total cost savings on a 1GW #floatingwindfarm of up to 10%.” “The Subsea Collector is composed of a 66kV wet mate connection system and #subseaswitchgear with supervisory control and data acquisition provided by Benestad and ABB, respectively. Windstaller Alliance, an alliance between Aker Solutions, DeepOcean, and Solstad Offshore, will carry out the installation. Aker Solutions will also provide the static export cable to shore.” https://lnkd.in/evYFxwsX Source- original post Read all my posts #MariusPreston

So much blue and yellow! This chart is beat up. Not enough vessels - still so many mob/demob and off-hire periods. Industry doing one-off mini-projects compared to what is needed to combat climate change. How much time is lost on mob/demob + off hire due to lack of industry standardisation?

In the coming weeks, the offshore high voltage station of Hollandse Kust (west Alpha) will be installed on the steel jacket some 50 kilometres off the coast of Egmond aan Zee. "This big power socket converts the energy produced by the wind turbines of Ecowende towards a higher voltage, so TenneT can transport it via two subsea cables to the land station in Wijk aan Zee and from there to the onshore grid in The Netherlands," explains Anne-Marie Taris, Interface Manager at TenneT TSO B.V. In this video Anne-Marie and Massimiliano Longhin, Electrical Package Manager at Ecowende, look back at building the offshore high voltage station together at the fabrication yard of Equans BeLux in Hoboken, Antwerp. Massimiliano: "The partnership with TenneT is great. From both parties, there is a great willingness to make the most out of this project." With an installed capacity of approximately 760 MW, the Ecowende wind farm can make about 3% of the current Dutch electricity demand greener. The plan is to commission the wind farm in 2026. #offshorewind #energytransition #teamwork #teamingupwithnature
