深水离岸站点是将大规模离岸风能引入沿海人口中心的尚未开发的机会。主要挑战是浮动海上风力系统的预计成本较高。这项工作对使用大型垂直轴风力涡轮机进行深水海上风电的新机遇进行了全面研究。由于该技术的固有特征，存在潜在的转型机会来解决使用垂直轴风力涡轮机的浮动风电的主要成本驱动因素。本报告的重点是评估这项新技术的技术潜力。评估这种潜力的方法是进行系统设计研究，重点是提高对技术性能参数的理解，同时寻找降低成本的机会。 VAWT 设计规范的开发是为了执行这些设计研究。为了更好地了解浮动 VAWT 系统的设计空间，对多种转子配置选项进行了全面的设计研究。然后针对每种候选转子配置对浮动平台和系泊装置进行尺寸调整和评估。初步 LCOE 估算和 LCOE 范围是根据每个主要涡轮机和系统组件的设计研究结果得出的。本研究的主要成果是对 VAWT 性能的综合技术评估和初步 LCOE 估算，表明在需要浮动系统的深水近海环境中，与传统 HAWT 相比，浮动 VAWT 可能具有有利的性能和成本，表明这项新技术值得进一步研究。
Deep-water offshore sites are an untapped opportunity to bring large-scale offshore wind energy to coastal population centers. The primary challenge has been the projected high costs for floating offshore wind systems. This work presents a comprehensive investigation of a new opportunity for deep-water offshore wind using large-scale vertical axis wind turbines. Owing to inherent features of this technology, there is a potential transformational opportunity to address the major cost drivers for floating wind using vertical axis wind turbines. The focus of this report is to evaluate the technical potential for this new technology. The approach to evaluating this potential was to perform system design studies focused on improving the understanding of technical performance parameters while looking for cost reduction opportunities. VAWT design codes were developed in order to perform these design studies. To gain a better understanding of the design space for floating VAWT systems, a comprehensive design study of multiple rotor configuration options was carried out. Floating platforms and moorings were then sized and evaluated for each of the candidate rotor configurations. Preliminary LCOE estimates and LCOE ranges were produced based on the design study results for each of the major turbine and system components. The major outcomes of this study are a comprehensive technology assessment of VAWT performance and preliminary LCOE estimates that demonstrate that floating VAWTs may have favorable performance and costs in comparison to conventional HAWTs in the deep-water offshore environment where floating systems are required, indicating that this new technology warrants further study.
