The invention discloses an extension method for an FPSO upper module. The extension method for the FPSO upper module comprises the following steps that S1, the distance between supporting legs of the upper module is determined according to the positions of FPSO ship body transverse ribs and ship body longitudinal ribs; s2, carrying out computational analysis; s3, according to the budget load and arrangement, the sizes of decks, layers and floor heights of the basic module structures are determined; s4, basic module supporting legs, stand columns, cross beams and inclined struts are planned to form a space frame, and expansion module interfaces are reserved; s5, carrying out computational analysis; s6, determining a module expansion direction according to the function requirements of the expansion module, and planning the structure of the expansion module; s7, expansion module supporting legs are installed in the expansion direction, and the expansion modules are hoisted and integrated; and S8, connecting a connection structure between the basic module and the extension module to complete the extension operation of the upper module. According to the extension method of the FPSO upper module, decomposition and integration operation of the large module are achieved, the project development and construction cost is reduced, and meanwhile the construction period is shortened.

    本发明公开了一种FPSO上部模块的扩展方法,该FPSO上部模块的扩展方法包括如下步骤:S1、根据FPSO船体横肋和船体纵肋位置确定上部模块的支腿间距;S2、开展计算分析;S3、根据预算荷载及布置,确定基本模块结构甲板、分层和层高的尺寸;S4、规划基本模块支腿、立柱、横梁和斜撑形成空间框架,并预留扩展模块接口;S5、开展计算分析;S6、根据扩展模块的功能需求,确定模块扩展方向,规划扩展模块结构;S7、在扩展方向上安装扩展模块支腿,吊装、集成拓展模块;S8、连接基本模块及扩展模块之间的连接结构,完成上部模块扩展作业。本发明提供的FPSO上部模块的扩展方法,实现对大型模块的分解和集成作业,降低项目开发建造成本,同时缩短了建造周期。
