🏆 IMHO, the award for best booth at #CLEANPOWER goes to Danish Wind Export for setting up an espresso machine and serving made-to-order drinks to attendees. ☕️ Fun facts about Denmark I learned while standing in line for my lavender latte: 🇩🇰Denmark has the highest proportion of wind in the world 🇩🇰Over 50% of energy in Denmark is supplied by wind power 🇩🇰Denmark is a global leader in wind export export across all aspects of the wind global supply chain (think Vestas and Siemens Gamesa) 🇩🇰Denmark was a first mover in wind, and started investing in the industry following the 1973 oil crisis

Inspiring milestone by Vattenfall's Horns Rev 1, world's first large-scale offshore wind farm. 👏 👏 Also worth mentioning that, comparing to newer wind farms with larger turbines, the O&M schedule at older sites can be busier, and with leaner budget and profit margin. Miros' real-time sea-state monitoring services have been helping Horns Rev 1 making best O&M decisions daily since 2019. They even like the real-time sea-state data to be public so all their teams and contractors can view when operating on-site without needing to frequently updating the data access list! You can view it on https://miros.app/ on any browser 😉

Hooray, the world´s first large-scale offshore wind farm has now turned 20! When Horns Rev 1 was built by the west coast of Denmark in 2002-03, offshore wind was quite an experimental and small industry. Since then a lot has happened and today offshore wind is a strong force in enabling fossil freedom - not least since Horns Rev 1 paved the way as a showcase for offshore wind. We at Vattenfall are proud to operate Horns Rev 1 together with our partners Ørsted, Vestas and Energinet.

📖 𝗥𝗲𝗮𝗱𝗶𝗻𝗴 𝗧𝗶𝗽: #𝗜𝗪𝗘𝗦-𝗕𝗹𝗼𝗴 𝗥𝗲-𝗽𝗼𝘀𝘁: 𝗩𝗲𝗿𝘀𝗮𝘁𝗶𝗹𝗲 𝗮𝗻𝗱 𝗳𝗹𝗲𝘅𝗶𝗯𝗹𝘆 𝗲𝗺𝗽𝗹𝗼𝘆𝗮𝗯𝗹𝗲 𝘀𝗲𝗿𝘃𝗶𝗰𝗲: 𝗮𝘂𝘁𝗼𝗺𝗮𝘁𝗲𝗱 𝗼𝗽𝘁𝗶𝗺𝗶𝘇𝗮𝘁𝗶𝗼𝗻 𝗼𝗳 𝗳𝗹𝗼𝗮𝘁𝗲𝗿𝘀 Our colleague Dr. Mareike Leimeister, one of the authors of this blog article, was at the #Floating Wind Days in Norway last month. A good opportunity to revisit this important topic: Compared to conventional #offshore wind turbines, "floaters" open up enormous #windenergy potential because they allow the development of offshore sites in deep waters. Since 2017, Fraunhofer IWES has been developing a tool for the automated optimization of floating wind turbines, with the aim of increasing the performance of the system and making it more cost-effective and competitive by improving the use of materials. 🌬 At Floating Wind Days, it was great to see how far the floating wind technology has already proceeded. However, there are still several challenges prevailing that need to be overcome and that were discussed at the event: ◾ How can floating wind technology become cost competitive with bottom fixed solutions?  ◾ How to pick the most suitable design out of the huge number of different floater concepts for a specific wind farm site?  ◾ How will maintenance and repair work, or even a major component replacement be performed for floating wind turbine systems?  ◾ How could floaters become most compatible with the wind turbine to be supported? 💡 Approaches towards addressing these challenges include, for instance, modular floater designs, add-on cranes on the floating wind turbine system, or integrated design approaches for the combined floating wind turbine system. Anyway, for the consideration of these features and innovative approaches optimization at early and detailed design levels is essential.

Deeper Dive into VAWTs vs. HAWTs: Efficiency Efficiency is a crucial factor when choosing a wind turbine. While HAWTs generally boast higher efficiency, VAWTs offer advantages in certain situations. Here's a closer look: -HAWTs: Peak efficiency around 45% wind speed, steadily declining as wind speed decreases. -VAWTs: Efficiency remains relatively constant across a range of wind speeds, making them more suitable for low wind areas. While efficiency is important, consider other factors like wind resource, available space, and noise level when making your decision. #windpower #technology #cleanenergy

How to increase certainty in #OffshoreWind? My colleagues Lars Ivar Leivestad and Richard Yen-Ting Chen share their thoughts on this crucial topic in the latest issue of PES Wind. 🌊💡 #KnowYourWaves Stefann Perrigot #SeaStateAsAService #RenewableEnergy #SustainableSolutions #OceanInsights #HarnessThePower #FloatingWind #Offshore #PESWind

2. Power from Low Speed Winds: Wind Harvester: The new Wind Harvester is based on a reciprocating motion that uses horizontal aero foils similar to those used on aeroplanes. It is virtually noise-free and can generate electricity at a low speed, which may result in less opposition to new installations. It will also be operational at higher wind speeds than current wind turbines

A giant floating wind turbine breaks loose at sea and drifts towards shipping: what now? ◾ Foreign agents have sabotaged a floating wind turbine and the towering structure has now escaped its moorings and is careening towards a tanker in a busy shipping lane. How do you regain control of it and avoid catastrophe? A competition has launched looking for answers. ◾ Floating turbines are taking wind power to waters and depths that were previously impossible to reach, opening up huge new swathes of ocean as a potential home for green power generation. ◾ Floating platforms can tackle these depths because rather than resting on solid foundations down to the seabed they are connected by mooring lines and anchors that can reach far further down ◾ Developer Corio Generation and Norwegian power producer Å Energi have launched a competition inviting start-ups to resolve a lingering and troubling question regarding the structures that keep the colossal turbines – potentially hundreds of metres tall – in place. What if they break? ◾ “While it may be very unlikely to happen,” the problem of how to take back control of a floating wind turbine that has escaped its anchorage remains “one of the challenges to be solved” for the industry, said Jarle Dyrdal, head of offshore wind at A Energi. ◾ Corio and Å Energi, which are partners on a floating offshore wind project in the Norwegian North Sea, are he said therefore “seeking input on how to develop innovative and effective approaches to tackling such a scenario.” ◾ Floating wind turbines often operate in “high-risk areas, such as seismic zones and busy shipping lanes,” says a briefing for the competition. This raises the “significant challenge of managing emergencies, including partial or complete mooring system failures.” ◾ “This calls for innovative solutions that ensure the safety of personnel, protect assets, and preserve the environment, all without necessitating the physical transfer of offshore personnel to these compromised structures.” ◾ The winner of the competition will be announced at the Floating Wind Days conference in Haugesund, Norway, at the end of May, and then work with experts at the companies to further develop the winning concept.
