GOALI/Collaborative Research: Efficient Multiline Mooring Systems for Floating Wind Turbines

该合作资助机会学术联络与工业（GOALI）项目旨在开发一种新颖的，集成的，网络化的多线系泊系统，用于浮动海上风力涡轮机，可以在材料和安装方面节省大量资金成本，从而有助于使海上风能成本与其他能源竞争。 降低海上风力发电的成本对于实现国家可再生能源目标和满足强劲增长的经济需求至关重要。行业合作伙伴Vryhof Anchor是海上结构锚系统的全球领导者，并越来越多地参与海上风电行业，包括为世界上第一台浮动海上风力涡轮机提供锚定系统。 Vryhof将通过其子公司Vryhof Americas与学术研究团队密切合作，以确保研究任务与工业需求密切相关，并确保学术研究得到最新工业进展的通知。 Vryhof还将担任学术团队和其他行业联系人之间的联络人。 为了成功地开发所提出的多缆系泊系统，研究必须解决浮动平台在不规则风浪状态下的动力学问题、系泊缆作用以及各种锚类型、土壤地层、本研究的主要目标是提供一条路径，以转换海上浮动风电场的设计，从一个涡轮机系泊系统被单独地设计和构造，其中用于整个风电场的系泊系统被设计为具有大大增加的材料和安装效率的网络系统。 具体的研究目标是：（1）生成理想化的土壤地层;（2）探索与多线概念兼容的风电场布局的几何设计空间;（3）开发海上风电场范围的空间相关风浪模型;（4）将系泊缆力建模为相关随机过程;（5）使用3D有限元分析分析锚行为;（6）评估候选多线锚设计的可行性和成本。 该项目通过Vryhof工业合作和与缅因大学示范项目的合作关系实现了广泛的影响。 教育协同作用通过马萨诸塞州风能IGERT计划和马萨诸塞州干多样性研究所和得克萨斯州A M AGEP计划的研究生教育活动发生。

This collaborative Grant Opportunities for Academic Liaison with Industry (GOALI) project seeks to develop a novel, integrated, and networked multiline mooring system for floating offshore wind turbines that can provide significant capital cost savings in terms of materials and installation, and thereby contribute to making offshore wind energy cost competitive with other sources. Reducing the cost of energy generated from offshore wind sources is critical to meeting national renewable energy goals and for meeting the needs of a robustly growing economy. The industry partner, Vryhof Anchors, is a world leader in anchor systems for offshore structures and has become increasingly involved in the offshore wind industry, including providing the anchoring system for the world's first floating offshore wind turbine. Vryhof, through its subsidiary Vryhof Americas, will work closely with the academic research team to ensure that research tasks are closely aligned with industrial needs, and that the academic research is informed by the latest industrial advances. Vryhof will also act as a liaison between the academic team and other industry contacts. To successfully develop the proposed multiline mooring system, the research must address issues of dynamics of floating platforms in irregular wind and wave states, mooring line actions, and the mechanics of anchor-soil interaction for a variety of anchor types, soil stratigraphies, and mooring geometry.The principal goal of this research is to provide a path to transformation of offshore floating wind farm design from one in which turbines mooring systems are designed and constructed individually to one in which the mooring system for the entire wind farm is designed as a networked system with greatly increased material and installation efficiency. Specific research objectives are to: (1) generate idealized soil stratigraphies; (2) explore the geometric design space for wind farm layout compatible with the multiline concept; (3) develop spatially correlated wind wave models for the extent of an offshore wind farm; (4) model mooring line forces as correlated random processes; (5) analyze anchor behavior using 3D finite element analysis; (6) evaluate candidate multiline anchor designs for feasibility and cost. The project achieves broad impact through the Vryhof industrial collaboration and partnership with demonstration projects based at UMaine. Educational synergy occurs through the graduate education activities of the UMass Wind Energy IGERT program and the UMass STEM Diversity Institute and Texas A&M AGEP programs.
