Sustainable station-keeping systems for floating wind

为了实现欧盟的净零目标，需要将海上风电部署率提高六倍，主要是在需要浮动海上风电（FOW）的深海。为了实现这一增长，FOW必须是经济的、可持续的，并得到广泛的供应链的支持。TAILWIND专注于FOW的位置保持系统，包括系泊线和锚定系统。该项目将为降低成本、减少环境影响和材料使用以及供应链多样化提供确定的机会。TAILWIND将整合新的实验证据，新技术和创新方法，跨系泊线和锚，并将量化整个浮动系统设计的收益。所有创新都将是可持续的设计，整合环境，社会和经济效益。对于系泊缆，将对新的合成绳索技术进行机械和化学测试，以证明其适用于小占地面积的“拉紧”系泊，验证新的响应模型。对于锚定，土工离心试验和先进的土壤元素测试将支持两个进步：（i）新的响应模型的长期负载特别是FOW，和（ii）新的锚类型的验证，包括集群锚是“安静”安装从小型船舶和适合共享系泊。系泊缆和锚的新技术将允许更小和更轻的位置保持系统，由更广泛的供应链制造和安装。TAILWIND将把这些模型提炼成系统优化工具，进一步优化浮式平台并降低成本。最后，综合生命周期评估将量化TAILWIND技术的经济、社会和环境影响。TAILWIND联合了来自8个欧洲国家的12个组织组成的多元化联盟，这些组织位于新兴的FOW发展地区，涵盖学术界，咨询，建筑和制造业。

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.
