Stinger Keel Floating Wind Turbine Foundation UK Concept Development

2009年，风力涡轮机提供了英国2%的电力需求[1]。到2019年，这一比例上升到20%[2]。英国政府致力于在未来十年内将海上风力发电能力翻两番，到2030年实现40 GW海上风力发电能力，其中1GW专用于浮动海上风力发电。浮式风力发电代表了海上风力发电的下一个前沿，涉及在锚定在更深水域的浮式结构上开发风力涡轮机。当前一代的海上涡轮机固定在浅沃茨的海床上，深达60米，这使得风力涡轮机能够在英格兰海岸周围扩展。在这个深度之外，有更大面积的海洋，有更强大和持续的风流。苏格兰、挪威、美国太平洋沿岸、日本、韩国和其他大陆架有限但国内和工业能源需求巨大的国家的市场可以从部署浮动风电场中受益，以实现向可再生能源的过渡。这为英国经济和劳动力提供了一个机会，因为它在北海深水石油和天然气开发以及沿海海上风电场方面拥有独特的经验。浮动能源系统有限公司在这两个领域都有经验，并正在与其英国合作伙伴合作，为发展中的全球浮动海上风电市场做准备。他们正在共同开发“毒刺龙骨基础概念”。它是一种基于为海上石油/天然气生产开发的浮动桁架柱概念的浮动结构，但包括配重龙骨和表面浮动单元之间的铰链连接的创新。这使得在码头区而不是在开放水域更有效地建造完整的基础涡轮机组件，并消除了对昂贵的重型起重浮式起重机的依赖。FESL及其工程合作伙伴应在运行涡轮机的情况下对托管架龙骨基础进行计算机和波浪水槽模拟，以全面评估动态运动，并评估新的制造技术，以提高施工的便利性，实现高批量生产率。最终交付成果包括全面详细和经过验证的施工计划，制造商可以从这些计划开始计划并计算向英国和全球市场交付多个基础结构单元的成本。[1] DECC历史电力数据（2013年）。[2] BEIS Digest of UK Energy Statistics 2020。[3] 2019年保守党宣言。

In 2009, wind turbines supplied 2% of the UK's electrical demand \[1\]. By 2019, this had risen to 20% \[2\]. The UK government is committed to quadruple offshore wind capacity over the next ten years to achieve a total of 40GW offshore wind generating capacity by 2030 with 1 GW dedicated to floating offshore wind \[3\]. Floating wind represents the next frontier of offshore wind power generation and involves development of wind turbines on floating structures anchored in deeper water.The current generation of offshore turbines are fixed to the seabed in shallow waters up to 60m deep which has enabled the expansion of wind turbines around England's coast. Beyond this depth lie much larger acreages of sea with more powerful and sustained wind flows. Markets in Scotland, Norway, the US Pacific Coast, Japan, Korea and other countries with limited continental shelf but large domestic and industrial energy demand can benefit from deployment of floating windfarms to achieve the transition to renewable energy. This presents an opportunity for the UK economy and workforce with its unique combination of experience in deep water North Sea oil and gas developments and coastal offshore windfarms.Floating Energy Systems Ltd has experience in both areas and is working with its UK partners to prepare for the developing global floating offshore wind market. Together, they are developing the Stinger Keel Foundation Concept. It is a floating structure based on the floating truss spar concept developed for offshore oil/gas production but includes the innovation of a hinged connection between the weighted ballast keel and surface floating unit. This enables more efficient construction of the complete foundation-turbine assembly at the quayside rather than in open water and removes dependency on costly heavy lift floating craneage.With Innovate UK funding, FESL and its engineering partners shall conduct computer and wave tank simulations of the Stinger Keel foundation with operating turbine to thoroughly assess dynamic motions as well as assess novel fabrication techniques to improve ease of construction and achieve high volume productivity. End deliverables include fully detailed and verified construction plans from which fabricators may start to plan and cost the delivery of multiple foundation structure units to UK and global markets.\[1\] DECC Historical Electricity data (2013).\[2\] BEIS Digest of UK Energy Statistics 2020\.\[3\] Conservative Party Manifesto 2019\.
