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.

这种小型企业技术转移（STTR）I期项目的更广泛影响是开发一项技术，该技术可从海上风能提供低成本的能源，并解锁当前技术无法访问的新市场，例如，当地较小的，当地维护的涡轮机较小的小种群，深层的沃特河地区，常规洪水不经济，并且缺乏深层港口。如果成功的话，全球影响可能有可能在Gigaton二氧化碳（CO2）等效/年的规模下抑制碳排放。拟议的技术是一种浮动的风力涡轮机，可以减少传统浮动涡轮机的重量的80％，并可以通过国内企业和就业机会在本地制造更多组件。新提出的建筑将进行测试，以确保其在海洋环境中生存并良好。关键的第一步是调整国家可再生能源实验室（NREL）世界一流的风波软件，以模拟系统的异常动作并证明其可行性。 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 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, test expands deployment into regions与当前技术无法访问，这增加了安装 /维护的移动性。这种浮动结构从未被设计过，该项目可能会深入了解有关湍流风，随机波，海洋电流，转子弹性和角动量以及动态叶片螺距和发电机控制的复杂叠加引起的负载和运动的几个问题。该STTR提案旨在解决关键的技术风险：适应NREL的模拟器OpenFast，以表征系统在复杂的浪潮，风和电流加载环境中运行的系统的独特动作，以及对负载和功率产生的影响。拟议的系统偏离了依赖于限制系统动议的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，然后证明它的动态行为符合认证所需的设计负载案例。该奖项反映了NSF的法定任务，并被认为是通过基金会的智力优点和更广泛的影响来通过评估来获得的支持。
