【摘要】：以一艘小型天然气液化船(FLNG)为例,采用数值方法模拟该FLNG进行尾输作业时的总体性能,对比分析了不同缆绳材料对于FLNG与LNG运输船(LNGC)之间相对运动的控制作用,分别根据尾输系统特定的限位要求和系泊设计规范,对两船相对运动及单点系泊系统动力响应结果进行校核。研究表明:两船相对运动与单点系泊动力响应结果满足外输作业要求。在系泊设计阶段,缆绳材料的选取对于保障外输方案的可行性具重要影响,系泊缆绳轴向刚度的选取必须能对两船体之间的水平方向位移的波浪频率响应起到控制作用。此外在外输过程中,尾输系泊缆绳将经历冲击张紧过程,导致张力幅值迅速上涨,设计时必须予以充分考虑。
[Abstract]:Taking a small natural gas liquefaction ship (FLNGG) as an example, the overall performance of the FLNG for tail transportation was simulated by numerical method. The control effects of different cable materials on the relative motion between FLNG and LNG carrier were compared and analyzed. According to the specific limit requirement and mooring design code of the trailing system, The results of the relative motion of two ships and the dynamic response of a single point mooring system are checked. The results show that the results of the relative motion and the dynamic response of a single point mooring meet the requirements of the outputting operation. The selection of cable material has an important influence on the feasibility of the transmission scheme. The selection of the axial stiffness of the mooring cable must control the wave frequency response of the horizontal displacement between the two ships. The tailing mooring cable will go through the process of impact tensioning, which leads to the rapid increase of tension amplitude, which must be fully considered in the design.
