海上风电行业的趋势已经表明，由于更强、更一致的风资源和美学问题的缓解，漂浮式海上风力涡轮机（FOWT）技术和深水沃茨中的安装。然而，支助系统的高资本成本仍然是一个主要障碍。因此，本研究提出了一种新型的，集成的，网络化的多线环锚（MRA）系统FOWT，可以提供显着的资本成本节约。该锚的其它吸引人的特征包括关于其可被部署的土壤条件范围的多功能性、相对高的岩土工程效率、精确定位的能力以及在非预期的扭转载荷下提供稳健性能的深嵌入。MRA与软粘土中吸力沉箱锚的有限比较研究表明，MRA在水平荷载下明显更有效，但在垂直荷载下仅略好。在设计中使用键控襟翼有望消除后一个性能问题。
The trends in the offshore wind industry have shown floating offshore wind turbines (FOWTs) technology and installation in deep waters due to stronger, more consistent wind resources and mitigation of aesthetic issues. Nevertheless, the high capital cost of the support systems remains a primary obstacle. Thus, this study presents a novel, integrated, and networked multiline ring anchor (MRA) system for FOWTs that can provide significant capital cost savings. Other attractive features of the anchor include versatility in regard to the range of soil conditions in which it can be deployed, relatively high geotechnical efficiency, capability for precise positioning and a deep embedment which provides for robust performance under unintended torsional loading. A limited comparative study of the MRA to a suction caisson anchor in soft clay shows the MRA to be clearly more efficient under horizontal loading, but only a marginally better under vertical loading. Incorporating keying flaps in the design has promise for eliminating the latter performance issue.
