【摘要】 FPSO是Floating Production Storage and Offloading的英文缩写，即浮式生产储油卸油装置，习惯上我们称为浮式生产储油船。它是集生产、储油、外输、生活、动力于一体的多功能采油设施，是海洋石油开发中非常重要、也是最有应用前景的装备之一。国外FPSO的设计建造始于二十世纪七十年代，经过多年的发展，国外公司对于FPSO关键技术的研究日趋成熟；虽然国内相关单位也对FPSO设计建造的部分技术进行了多年研究并取得了一定成果，但是对FPSO的总体设计尚缺乏系统分析，对于FPSO中关键技术之一“系泊系统的设计”尚缺乏理论研究。本论文对影响浮式生产储油设施FPSO设计建造的因素进行了综合分析，并对系泊系统的设计进行了重点研究。基于对FPSO相关规范的研究，结合我国自行设计建造的15万吨级PFSO的实际经验，采用了层式分析法和模糊评判法，在该船型的方案论证、总布置、可靠性评估等方面做了详细分析，总结得出FPSO的总体设计框架与原则，设计单位可以根据该原则对承接的FPSO进行初步设计。通过将浮式生产储油设施FPSO和普通油船进行对比分析，首次给出一系列反映两者区别的直观表格，并在此基础上归纳了设计建造FPSO所必须考虑的影响因素，可供船厂建造FPSO过程中结合已有的油船建造经验进行参考分析。应用流体力学理论和数学工具开发了FPSO环境载荷的计算方法，对系泊系统的设计和模型实验进行了研究。如何确定外部环境载荷，是本部分研究的重点。采用线性化Weibull概率密度函数分析得到设计波参数，并根据三维源汇分布方法建立浮体运动与波浪荷载计算方法，完成了一浮式生产储油船(FPSO)在波浪中的运动响应和船体表面水动力压力分布以及总体荷载的概率特性的计算，并以此为基础对FPSO的系泊系统的设计和模型实验开展研究。更多还原

【Abstract】 FPSO is the abbreviation for Floating Production, Storage and Offloading unit. It is a multifunctional vessel designed for offshore production and storage and offloading of oil or gas. Now FPSO is one of the most important equipments in the offshore oil and gas industry and has good future prospects. The design and manufacture of FPSO started from 1970s. After thirty years development, the studies on the key technologies of the design and fabrication of the FPSO is more and more mature in the world. In China, researches about FPSO have started for a long time and there are many important results. But the overall design of FPSO has not been analyzed systematicly. And there is still short of research on the design of the mooring system.This paper give a synthetical analysis on the important influential factors that have been experienced during the design and fabrication of a FPSO, and the research is mainly focused on the design of the mooring system.Based on the study on Classification Society Rules about FPSO, and combined with the experience of design and manufacturing of a 150,000t FPSO, detailed analysis has been made about the overall design, general arrangement and reliability evaluation and other aspects using the analytic hierarchy process and fuzzy evaluation method. The principles in the overall design of the FPSO have been summarized. It is useful in the preliminary design of new FPSO.In order to let the shipyards can use the experiences of the building of general oil ship into the process of FPSO’s manufacture, the differences between the FPSO and common oil ship are compared and listed in a table for the first time. The influential factors that ought to be considered in the design and fabrication of the FPSO are concluded based on the research.Using the hydrodynamic theory and numerical simulation method, a computer program about the computation of environment loads on FPSO has been developed. The design and model experiment of the mooring system has been studied. The research is mainly focused on the determining of environment loads. The linear Weibull function is used to calculate the parameter of design wave. Using the 3d panel method, the computation method of the wave load and motion of floating body has been developed. The computation about a FPSO’s motion and hydrodynamic pressure on the hull surface has been carried out, and the long-term distribution of the loads is analyzed. The result is used in the design and model experiment of a FPSO.更多还原
