提出了一种基于传统拉紧系缆的新型混合系泊系统。在每根系泊线的下端附加一系列的团块重量，形成悬链线形状。一些浮标被连接到缆绳的上端，以减少每根系泊绳的顶部张力。为了验证这种新型混合系泊系统的优势，我们研究了采用该混合系泊系统的半潜式平台的运动响应。采用时域法计算了线的顶张力。对比张力系泊系统的结果可以发现，采用混合系泊系统可以减小缆绳上的张力，而对运动响应几乎没有影响。此外，在每条系泊线的下端形成悬链线形状，可以降低对锚杆抗上拉能力的要求。我们还进行了参数化研究，以探讨浮标的最佳位置和体积。重点讨论了水深的影响。
A new hybrid mooring system based on the traditional taut mooring lines was proposed in the present study. A series of clump weights were attached to the lower end of each mooring line to form a catenary shape. Some buoys were connected to the upper ends of the lines to reduce the top tension on each mooring line. In order to verify the advantages of this new hybrid system, we investigated the motion responses of a semi-submersible platform moored by the proposed hybrid mooring system. The top tension on the lines was also calculated by using the time domain method. Comparing the results from the taut mooring system, it can be found that the tension on the lines could be reduced by using the present hybrid mooring system, while the motion responses were hardly influenced. Furthermore, a catenary shape was formed at the lower end of each mooring line, which could reduce the requirement of the anti-uplift capacity of the anchors. We also carried out the parametric study to investigate the optimal position and volume of the buoys. The discussions were highlighted on the influence of the water depth.
