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.

这种与行业联络（Goali）项目的学术联络机构的合作赠款机会旨在开发一种新颖，集成和网络的多行系泊系统，用于漂浮在海上风力涡轮机上，这些系统可以在材料和安装方面节省大量资本成本，从而有助于与其他来源竞争离岸风能竞争。 降低海上风能源产生的能源成本对于满足国家可再生能源目标以及满足不断增长的经济需求至关重要。该行业合作伙伴Vryhof Anchors是近海结构的锚定系统领域的领导者，并且已经越来越参与离岸风能行业，包括为世界上第一个浮动海上风力涡轮机提供锚定系统。 通过其子公司Vryhof Americas，Vryhof将与学术研究团队紧密合作，以确保研究任务与工业需求紧密一致，并以最新的工业进步为学术研究提供了信息。 Vryhof还将在学术团队与其他行业联系之间充当联络。 为了成功地开发拟议的多行系系泊系统，该研究必须解决不规则的风和波状浮动平台的动态问题，系泊线的行动以及各种锚固类型，土壤地层的锚固机制，以及割模的几何形状以及这项研究的主要目标是为Off Off Offer of Floess构建的途径，这是一个构造的途径。整个风电场的系泊系统被设计为一个网络系统，其材料和安装效率大大提高。 特定的研究目标是：（1）产生理想的土壤地层； （2）探索与多行概念兼容的风电场布局的几何设计空间； （3）在海上风电场的范围内开发空间相关的风波模型； （4）模型系泊线力作为相关的随机过程； （5）使用3D有限元分析分析锚固行为； （6）评估候选多行锚设计的可行性和成本。 该项目通过Vryhof工业合作以及与Umaine的示威项目的合作伙伴关系实现了广泛的影响。 教育协同作用是通过UMass Wind Energy Igert计划的研究生教育活动以及UMass STEM多样性研究所和德克萨斯州A＆M Agep计划进行的。
