Sustainable station-keeping systems for floating wind

要实现欧盟的净零目标，需要将海上风能布置率提高六倍，主要是在需要漂浮海上风能(FOW)的深海地区。要实现这一增长，FOW必须经济、可持续并得到广泛供应链的支持。顺风的重点是FOW的站位保持系统，包括系泊和锚定系统。该项目将释放已确定的降低成本、减少对环境的影响和材料使用以及供应链多样化的机会。顺风将整合新的实验证据、新技术和创新方法，跨越系泊绳索和锚，并将量化由此产生的整体浮动系统设计的好处。所有创新在设计上都将是可持续的，整合了环境、社会和经济效益。对于系泊绳索，新的合成绳技术将进行机械和化学测试，以证明它们适用于小面积的“紧”系泊，从而验证新的反应模型。在锚定方面，土工离心机测试和先进的土壤元素测试将支持两项进展：(I)针对FOW的长期载荷的新响应模型，以及(Ii)新型锚具类型的验证，包括从小船上“静默”安装并适合于共享系泊的集束式锚具。锚链和锚的新技术将允许更小、更轻的站位保持系统，由更广泛的供应链制造和安装。顺风将把模型提炼成系统优化工具，实现进一步的浮子优化和成本降低。最后，综合生命周期评估将量化顺风技术对经济、社会和环境的影响。顺风联合了一个由来自8个欧洲国家的12个组织组成的多元化联盟，这些组织分布在新兴的FOW发展地区，涵盖学术界、咨询业、建筑业和制造业。

To meet EU net zero targets requires a six times increase in offshore wind deployment rate, primarily in deep seas where floating offshore wind (FOW) is needed. To achieve this growth requires FOW to be economic, sustainable and supported by a wide supply chain. TAILWIND is focussed on station-keeping systems of FOW, which comprise mooring lines and anchoring systems. The project will unlock identified opportunities for cost reduction, reduced environmental impact and material use, and also supply chain diversification. TAILWIND will integrate new experimental evidence, novel technologies and innovative methodologies, across mooring lines and anchors, and will quantify the resulting benefits for the overall floating system design. All innovations will be sustainable-by-design, integrating environmental, societal and economic benefits. For mooring lines, new synthetic rope technologies will be mechanically and chemically tested to demonstrate their suitability for small-footprint ‘taut’ moorings, validating new response models. For anchoring, geotechnical centrifuge testing and advanced soil element testing will underpin two advances: (i) new response models for the long-term loading particular to FOW, and (ii) the validation of novel anchors types including cluster anchors that are “silently” installed from small vessels and are suited to shared moorings. The new technologies for mooring lines and anchors will allow smaller and lighter station keeping systems, manufactured and installed by a wider supply chain. TAILWIND will distill the models into system optimisation tools, unlocking further floater optimisation and cost reduction. Finally, an integrated life cycle assessment will quantify the economic, social and environmental impact of TAILWIND’s technologies. TAILWIND unites a diverse consortium of 12 organisations from 8 European countries, located across the emerging FOW development regions, and spanning academia, consulting, construction and manufacture.
