波流联合作用下双船吊装系统的建模与仿真

Modeling and Simulation of Twin Marine Lifter System under Combined Action of Waves and Currents

参考国内外相关文献,结合双船起吊具体施工过程和力学特性,建立双船吊装系统模型。利用大型水动力分析软件OrcaFlex对双船吊装系统的运动响应进行时域求解,分析波流方向、波高、吊放速度以及吊缆拉伸刚度等因素对吊缆张力和吊物运动的影响。分析结果可作为双船吊装系统吊装作业安全性评估的理论依据,对双船吊装系统在海洋工程中的应用具有一定的参考价值。

Referring to the domestic and foreign literatures, the twin marine lifter system model is set up based on the construction process and mechanical property of twin marine lifter. To analyze the influence of wave-current direction, wave height, hoisting speed and cable axial stiffness on the cable tension and motion of crane load, the time-domain computation of response of motion of the twin marine lifter is solved with numerical simulation software Orca Flex. The analyzing result can be used as the theoretical basis of the safety assessment for the twin marine lifter system, which has certain reference value for the application of the twin marine lifter system in offshore engineering.
