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.

该合作资助机会学术与工业联络（GOALI）项目旨在为浮动式海上风力涡轮机开发一种新颖的、集成的、网络化的多线系泊系统，该系统可以在材料和安装方面显着节省资本成本，从而有助于使海上风能的成本与其他来源相比具有竞争力。 降低海上风电发电成本对于实现国家可再生能源目标和满足经济强劲增长的需求至关重要。行业合作伙伴 Vryhof Anchors 是海上结构锚固系统的全球领导者，并越来越多地涉足海上风电行业，包括为世界上第一台浮动式海上风力涡轮机提供锚固系统。 Vryhof 将通过其子公司 Vryhof Americas 与学术研究团队密切合作，确保研究任务与工业需求紧密结合，并确保学术研究了解最新的工业进展。 Vryhof 还将充当学术团队和其他行业联系人之间的联络人。 为了成功开发所提出的多线系泊系统，研究必须解决不规则风浪状态下浮动平台的动力学问题、系泊线作用以及各种锚类型、土壤地层和系泊几何结构的锚-土相互作用力学问题。这项研究的主要目标是提供一种海上浮动风电场设计从单独设计和建造涡轮机系泊系统到单独设计和建造的转变路径。 整个风电场的系泊系统被设计为网络化系统，大大提高了材料和安装效率。 具体研究目标是：（1）生成理想化的土壤地层； (2)探索兼容多线理念的风电场布局几何设计空间； (3) 开发海上风电场范围内的空间相关风浪模型； (4) 将系泊线力建模为相关随机过程； (5) 使用3D有限元分析来分析锚的行为； (6)评估候选多线锚设计的可行性和成本。 该项目通过 Vryhof 工业合作以及与缅因州示范项目的伙伴关系取得了广泛的影响。 麻省大学风能 IGERT 项目、麻省大学 STEM 多样性研究所和德克萨斯 A&M AGEP 项目的研究生教育活动产生了教育协同作用。
