海洋可再生能源装置使用合成系泊绳是最近才出现的情况。尽管目前在海上工业中使用，但MRE系泊部件通常会受到高度动态载荷的影响，因此需要详细描述操作和长期部件性能，以进行生命周期分析和操作管理。为了解决该应用中与合成系泊部件相关的不确定性，在MERiFIC（远外围和岛屿社区海洋能源）财团的资助下，法国IFREMER和英国埃克塞特大学对尼龙6平行股绳样品进行了拉伸实验。测量报告从谐波加载测试与不同的初始bedding-in水平，用于调查的影响载荷历史上的即时动态性能的绳索。根据西南系泊试验设施（SWMTF）记录的系泊张力，还施加了两种不规则载荷状态。提供数据集以促进绳索建模工具的开发。对于研究的负载制度，它被发现的操作性能的绳索的瞬时负载-应变特性的强烈影响。这项研究提供了独特的洞察力的刚度和阻尼性能的合成绳的上下文中的负载制度相关的MRE设备。
The utilisation of synthetic mooring ropes for marine renewable energy (MRE) devices is a recent occurrence. Despite current use in the offshore industry, MRE mooring components are typically subjected to highly dynamic loads, necessitating the detailed characterisation of operational and long-term component performance for lifecycle analysis and operations management. To address the uncertainties associated with synthetic mooring components in this application, tension experiments have been conducted on nylon 6 parallel-stranded rope samples at IFREMER, France and the University of Exeter, UK under the consortium MERiFIC (Marine Energy in Far Peripheral and Island Communities). Measurements are reported from harmonic loading tests with different initial bedding-in levels used to investigate the influence of load history on the immediate dynamic properties of the rope. Two irregular load regimes were also applied based on mooring tensions recorded by the South West Mooring Test Facility (SWMTF). Datasets are provided to facilitate the development of rope modelling tools. For the load regimes studied it was found that the operational performance of the rope is strongly influenced by the instantaneous load-strain characteristic. This study provides unique insight into the stiffness and damping properties of synthetic rope in the context of loading regimes relevant to MRE devices.
