摘　　要：结合浮船坞和某大型集装箱船燃料舱环段的各项参数,对大型集装箱船燃料舱环段横向过驳至浮船坞的方案进行研究。采用NAPA软件对船舶燃料舱环段横向过驳的浮船坞进行压载水配载,得到合理的横向过驳配载方案;采用PATRAN软件对船舶燃料舱环段横向过驳过程中的3个典型工况(搁置、过驳和落墩)进行有限元分析,验证该横向过驳方案的可行性。结果表明,大型集装箱船燃料舱环段和浮船坞模型在结构强度方面满足衡准要求,且舱段变形在合理范围内,说明该燃料舱环段横向过驳浮船坞方案是可行的。Based on the parameters of the floating dock and the fuel tank ring section of a large container ship,a study is conducted on the scheme of lateral transfer of the ring section to the floating dock.The NAPA software is used to perform ballast water loading of the floating dock to be used for lateral transfer,to obtain a reasonable lateral transfer loading plan.At the same time,the PATRAN software is used to conduct finite element analysis on three typical working conditions(shelving,transporting,and pier landing)during the lateral transfer process of the fuel tank ring section,to verify the feasibility of the scheme.The results show that the fuel tank ring segment and floating dock model of large container ships meet the structural strength requirements,and the deformation of the tank segment is within a reasonable range,indicating that the lateral transfer of the fuel tank ring segment to the floating dock scheme is feasible.This study can serve as a reference for the design and construction of floating dock structures,such as the lateral connection of liquefied natural gas tank sections or other floating body launches in the future.
