随着我国海上石油天然气勘探不断向深水方向发展，圆筒形FPSO逐步在深水环境中得到推广。为掌握这种新型平台的水动力特性与响应特点，以作业于英国北海的壳牌企鹅FPSO为研究对象，确定其主要结构参数，利用Ansys/Workbench有限元软件建立圆筒形FPSO的水动力模型，对其结构进行了初步水动力分析和强度校核；并在不同的环境工况下进行时域运动响应比较，分析圆筒形FPSO的水动力性能；最后，通过改变圆筒形FPSO外型尺寸，进行时域运动响应分析和参数比较，研究其外型变化对水动力性能的影响。
As the offshore oil and gas exploration in our country continues to develop in the deep water direction, cylindrical FPSO has been gradually popularized in the deep water environment. In order to master the hydrodynamic characteristics and response characteristics of this new type of platform, the Shell Penguin FPSO operating in the North Sea of the United Kingdom is taken as the research object, and its main structural parameters are determined. The hydrodynamic model of cylindrical FPSO is established by using Ansys/Workbench finite element software, and the preliminary hydrodynamic analysis and strength check of its structure are carried out. The time domain motion response was compared under different environmental working conditions, and the hydrodynamic performance of cylindrical FPSO was analyzed. Finally, the time domain motion response analysis and parameter comparison were carried out by changing the cylindrical FPSO shape size, and the influence of its shape change on hydrodynamic performance was studied.
