摘要
为配合我国南海重要岛礁陆域拓展及海洋资源开发,提出了一种基于新型单桩缓冲系泊与波浪能装置(WEC)集成的具有潮汐自适应特性的模块化浮体结构系统。基于三维势流理论,综合考虑浮体模块与单桩缓冲结构的相对运动及相关波浪能装置的机械耦合机理,重点研究了新型单模块浮式结构系统在典型海况下的动力响应特征,获得了单桩缓冲系泊系统的初步优化设计参数,并对极端海况进行安全校核,提出了优化自存策略。数值结果表明,此带有波浪能装置的新型单桩缓冲系泊系统,不仅可以有效地降低浮体模块的运动响应幅值并改善平台舒适度,还可以获得可观的发电量,而且在极端海况下,可以通过调整阻尼装置系统来稳定浮体模块的运动。
In order to support the expansion of important islands and reefs as well as the development of marine resources in South China Sea,a modular floating structure based on a novel monopile dolphin-fender mooring system has been proposed,which is self-adaptive for the tidal effect with the function of wave energy converter(WEC).Considering both relative motions between the floating module and the monopile dolphin structure and the mechanical coupling mechanism of the wave energy converter,this work is focused on the dynamic response characteristics of a new single module system in typical sea cases,and the preliminary optimal design parameters of the monopile dolphin-fender mooring system have been obtained,based on three-dimension potential theory.The security checking under the extreme sea condition has been done,and a survival optimization strategy is proposed.The results indicate that the new dolphin-fender mooring system with the wave energy converter can not only reduce motion responses of the floating module,but also can improve its sense of the comfort with considerable wave energy contribution.Under the extreme sea condition,the motion of floating module can be stabilized by adjusting the damping system.
