𝐖𝐨𝐫𝐥𝐝 𝐌𝐢𝐠𝐫𝐚𝐭𝐨𝐫𝐲 𝐁𝐢𝐫𝐝 𝐃𝐚𝐲: 𝐓𝐚𝐤𝐢𝐧𝐠 𝐬𝐞𝐚𝐛𝐢𝐫𝐝 𝐟𝐥𝐢𝐠𝐡𝐭 𝐫𝐞𝐠𝐢𝐬𝐭𝐫𝐚𝐭𝐢𝐨𝐧 𝐭𝐨 𝐧𝐞𝐰 𝐡𝐞𝐢𝐠𝐡𝐭𝐬 🕊 Tomorrow, we celebrate World Migratory Bird Day, honouring the incredible journeys of migratory birds and highlighting the importance of ensuring their protection. Offshore wind energy development could intersect with bird migration routes, presenting both challenges and opportunities for conservation efforts. Balancing renewable energy expansion with bird protection requires careful planning, and the importance of multi-sensor bird detection technology that monitors bird behaviour around offshore wind farms cannot be overstated. A DHI study for the European energy company Vattenfall finds that seabirds deliberately avoid rotor blades at offshore wind farms. These findings could pave the way for simpler permit processes for offshore wind power by improving our knowledge about seabird collision risk.

PNNL studies how seabirds and offshore wind turbines can coexist.

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.

📌 Webinar: Offshore wind development and underwater noise Hosted by: University College Cork, MaREI, Green Tech Skillnet and Wind Energy Ireland When: 11am - 1pm, Tuesday 8th October - - - - - - - - - - Ireland has ambitious offshore wind targets set out by the Climate Action Plan to reach 20 GW of offshore wind by 2040 and 37 GW by 2050. As the Phase 1 projects progress through the planning system, and as the next phase located within in the south coast DMAP moves closer towards an ORESS auction, work is underway to develop updated guidance for the management of underwater noise particularly with respect to the assessment, monitoring and mitigation of any potential risks to marine mammals. There are different approaches to the management of underwater noise across Europe and considerable variability in data availability, marine conditions and species distributions in different bodies of water. Finding the right approach for Ireland needs to take all of this into account to ensure that any new guidance will be fit for purpose, and ongoing cross sectoral collaboration and stakeholder engagement will continue to be an essential element for successful outcomes. This expert panel of speakers joining us from their offshore wind industry, environmental NGO, consultancy, research and academia roles have been brought together to share their perspectives and discuss where Ireland is today with the management of underwater noise, the challenges and opportunities ahead with different approaches, and what may be needed to bridge the gap to be able to implement new UWN guidance for Ireland to best support both the protection of marine life and the development of ORE to reach our climate targets.

Operating for the Directorate General for Energy and Climate (DGEC), Météo-France has selected Akrocean to collect offshore wind, wave, and current data for potential offshore wind farm sites in France. The framework contract won by Akrocean includes several measurement campaigns that will be conducted on all the French coastlines over four years, according to the needs and the de-risking schedule issued by the French government. They will be carried out using a fleet of floating LiDAR buoys, for a minimum period of twelve months. These campaigns can be extended for a further twelve months. “We’ve had the opportunity to develop our oceanographic offering with the additional local content provided by Energie de La Lune. We will continue in this way, to use local maritime resources, which are necessary for deployments at sea,” said Marine Colin, Project Manager. This is not the first time Météo-France awarded a contract to Akrocean. In 2020, the company secured a contract to supply floating LiDARs for future offshore wind projects in France. France has set a target of reaching 18 GW of offshore wind capacity by 2035 and 40 GW by 2050. The country’s first commercial-scale wind farm, the 480 MW Saint-Nazaire, was fully commissioned in November 2022. https://lnkd.in/enqKchNg

Yesterday was Global Wind Day, could not help writing something down.. below video recorded SANY 2000t crawler crane installed DEC 18MW 260 HH146 (126m blade weights about 50t, integrated drive train weights about 200t) on June 5th 2024, the pad is less than 1km away to SE 11MW 208 HH115 installed in less than 2yrs ago.. Thanks to Vestas' carbon fiber blade beam patent expired about 2yrs ago and the strongest supply chain of the world as well as the capital market of the lowest threshold , OFW grows fast in China and typical CAPEX of +15MW OFW including Tower is only about 500US$/kW, OPEX budget in 5yr warranty is only 7US$/kW/yr here vs in EU or US typical CAPEX of 15MW OFW including Tower is around 1300-1500US$/kW and OPEX budget for 30 or 35yr O&M warranty is nearly 70US$/kW/yr .. In two completely different ecosystem, the turbine fleet and its supply chain are also completely different: one is Design to CAPEX vs Design to LCoE..  No doubt Chinese product and its value chain will dominate in similar or lower QHSE standard market like Mideast, North Africa, BRICS, Mid Asia and Southeast Asia, etc.. Good or bad, China ‘s national system and more hardworking Chinese people are profoundly shaping the future and leaving irreversible footprint of the wind power industry with Chinese speed..

A new restriction blocks wind turbines in Dobrogea, considered dangerous obstacles for planes Developers of wind projects in Dobrogea have been facing a new problem for some time, namely the lack of approval from the aeronautical authority, which recently considers that the turbines are too high and refuses to issue positive approvals for new constructions, after the change in the minimum altitude level of flight (MOCA – minimum obstacle clearance altitude), claim market sources consulted by Energynomics . https://lnkd.in/dpMfbn4c

📖 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.
