【摘要】：FSRU在恶劣环境条件下的作业和安全停靠性能与系泊缆张力、靠垫挤压应力、船体6自由度运动等参数有关。针对FSRU码头处海洋环境条件,进行FSRU不同装载状况的模型实验,获得FSRU的6自由度运动及其系泊载荷的动力特性。基于三维辐射和绕射理论,使用Sesam软件进行频域计算,以此为基础在相应海洋环境条件下进行时域耦合分析,获得FSRU 6自由度运动、系泊载荷、靠垫应力等参数的响应时历。结果表明:30%装载、横浪条件下FSRU的运动响应最大,系泊缆张力未达到破断值,靠垫压力超过其压缩60%时的载荷;模型实验对FSRU运动响应和系泊缆张力的预测结果可信,靠垫受力情况需要数值仿真进行辅助研究。
[Abstract]:The operation and safe docking performance of FSRU under harsh conditions are related to the mooring cable tension, cushion extrusion stress, and the motion of the hull with 6 degrees of freedom. According to the marine environment conditions at FSRU wharf, the model experiments of different loading conditions of FSRU are carried out, and the dynamic characteristics of 6-DOF motion and mooring load of FSRU are obtained. Based on the theory of three-dimensional radiation and diffraction, the frequency domain calculation is carried out by using Sesam software. Based on the time-domain coupling analysis under the corresponding marine environment, the response time history of the parameters such as FSRU 6-DOF motion, mooring load and cushion stress is obtained. The results show that under the condition of 30% loading, the FSRU has the largest motion response, the mooring tension does not reach the breaking value, and the cushion pressure exceeds the load when it compresses 60%, and the prediction results of the FSRU motion response and mooring cable tension are credible. The bearing condition of cushion needs to be studied by numerical simulation.
