The broader impact of this Small Business Technology Transfer (STTR) Phase I project is to develop a technology that delivers low cost of energy from offshore wind and unlocks new markets inaccessible to current technology, e.g., small populations with smaller, locally-maintained turbines, deep water locations where conventional floaters are not economical, and regions lacking deep ports. If successful, the global impact may have the potential to suppress carbon emissions at the scale of gigaton carbon dioxide (CO2) equivalent/year. The proposed technology is a floating wind turbine that may reduce 80% of the weight of a conventional floating turbine and makes it possible to fabricate more components locally, with domestic businesses and jobs. The newly proposed architecture will be tested to ensure it survives and operates well in the ocean environment. The crucial first step is to adapt the National Renewable Energy Laboratory’s (NREL) world-class wind-wave software to simulate the unusual motions of the system and demonstrate its viability. The end goal is the commercialization of a disruptive offshore wind turbine, developed in the U.S. and deployed globally, that can outcompete all of today’s designs, in a market estimated to soon reach ~$100 billion/year.This project seeks provide the intellectual foundation that leads to a first-of-its-kind class of offshore wind turbines that have minimal weight, that rides on top of the waves, taht expands deployability into regions inaccessible with current technology, and that increases mobility for installation / maintenance. Such a floating structure has never before been designed and this project may provide deep insight into several questions about the loading and motions that arise from a complex superposition of turbulent wind, random waves, ocean current, rotor elasticity and angular momentum, and dynamic blade pitch and generator control. This STTR proposal seeks to address a critical technical risk: adaptation of NREL’s simulator OpenFAST to characterize the unique motions of the system operating in a complex environment of loading from wave, wind and current and the resulting impacts on loading and power production. The proposed system departs from long-standing industry conventions that have relied on the design principle of limiting system motions. The results of the simulator may be used to refine the system design and then demonstrate that it's dynamic behavior complies with the design load cases required for certification.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该小型企业技术转让 (STTR) 第一阶段项目的更广泛影响是开发一种技术，通过海上风电提供低成本能源，并开辟现有技术无法进入的新市场，例如，使用较小的本地维护涡轮机的小人口如果成功的话，全球影响可能会抑制每年十亿吨二氧化碳（CO2）当量的碳排放。漂浮式风力涡轮机这可以减轻传统浮动涡轮机 80% 的重量，并可以在本地制造更多组件，国内企业和就业机会将对新提出的架构进行测试，以确保其在海洋环境中生存并良好运行。的目标是采用国家可再生能源实验室 (NREL) 的世界级风波软件来模拟系统的异常运动并证明其可行性，最终目标是将在美国开发并部署的颠覆性海上风力涡轮机商业化。全球范围内，在估计很快将达到每年约 1000 亿美元的市场中，它可以超越当今所有的设计。该项目旨在提供知识基础，以实现同类首创的重量极轻的海上风力涡轮机，漂浮在波浪之上，将可部署性扩展到当前技术无法到达的区域，并增加了安装/维护的机动性，以前从未设计过这样的浮动结构，该项目可以深入了解有关负载和运动的几个问题。那该 STTR 提案旨在解决关键的技术风险：采用 NREL 的模拟器 OpenFAST 来表征独特的运动。系统在波浪、风和水流负载的复杂环境中运行以及由此对负载和电力生产产生的影响。所提出的系统背离了依赖于限制系统设计原则的长期行业惯例。模拟器的结果可用于完善系统设计，然后证明其动态行为符合认证所需的设计负载情况。该奖项反映了 NSF 的法定使命，并通过使用基金会的评估被认为值得支持。智力价值和更广泛的影响审查标准。
