摘     要:FPSO是综合性的大型海上石油生产基地,在石油被开采出来之后，它可以将油和气分离，然后储存原油产品。与张力腿等海洋平台相比较，FPSO在抗风浪能力方面稍胜一筹，而且FPSO可以适应不同的水深，可以进行移动来重复利用。因此，大多数深海或浅海海域的油田，都可以使用FPSO进行开发。一般情况下，在特定的海域作业的FPSO都是采用永久性的系泊方式,所以FPSO不能够像穿梭油轮等运输型船舶在遭遇恶劣海况时进行避航。由此体现出对FPSO与运输船舶两者组成的系统的水动力分析的必要性。

本文进行的主要工作有：

一、 针对FPSO和穿梭油轮的系泊和连接要求等进行调研分析，确定两船主尺度、主要参数，以此来初步设计FPSO和穿梭油轮的独立模型。

二、 确定系泊方式和连接方式，以及系泊缆绳、连接缆绳和护舷的主要参数。

三、 利用AQWA软件建立耦合模型。

四、 对FPSO和穿梭油轮的流体性能进行频域分析，包括RAO、附加质量、辐射阻尼和一阶波浪激励力。

五、 给定风、浪、流载荷参数，开展FPSO和穿梭油轮时域分析，分析系泊系统、连接系统和护舷的受力以及两船之间的相对位移。

Abstract:FPSO is a comprehensive large-scale offshore oil production base where the oil can be separated from oil and gas after it is mined, it can store the crude oil products. Compared with offshore platforms such as tension legs, FPSO is slightly better in terms of resistance to wind and waves, and FPSO can adapt to different water depths and can be moved for reuse. As a result, most of the deep-sea or shallow-sea oil fields that are far from the coast can be developed by FPSO. In general, FPSO operating in a particular area of the sea are permanently mooring, so FPSO can’t escape as a result of transport ships such as shuttle tankers in the event of severe sea conditions. It is necessary that research hydrodynamic of the system consisting of both FPSO and transport ships.

Firstly, for the FPSO and shuttle tanker mooring and connection requirements and other research and analysis to determine the two ship master scale, the main parameters, in order to initially design FPSO and shuttle tanker independent model.

Secondly, determine the mooring methods and connection methods, as well as mooring cables, connecting cables and fenders of the main parameters.

Thirdly, use the AQWA software to establish a coupling model.

Fourthly, do the FPSO and shuttle tanker fluid performance frequency domain analysis, including RAO, additional quality, radiation damping and first-order wave excitation force.

Fifthly, choose the wind, wave, flow load parameters to carry out FPSO and shuttle tanker time domain analysis, analysis of mooring system, connecting system and fender force and the relative displacement between the two ships.

Key words:   FPSO and shuttle tanker；performance analysis；frequency domain and time domain analysis
