摘　　要：为了解决现有传统船型、圆柱筒型和棱柱型浮式生产储油系统(FPSO)的性能局限,提出了一种具有沙漏外形,并配有各种生产和生活功能模块的新型沙漏式FPSO.利用基于频域势流理论的边界元数值模拟和谱分析方法分析浮体在波浪中垂荡和纵摇运动性能,结合概率统计理论分析甲板上浪概率,采用变排水量法计算浮体的静稳性曲线.最后,与挪威Sevan Marine公司设计的圆筒形FPSO浮体模型和中海油公司设计的八角型FPSO浮体模型进行对比.结果表明,新型沙漏式浮体外形设计能够显著地提高FPSO的稳性和各项水动力性能,可以为深水油气开发提供一种有效的新型工程装备和解决方案.In order to overcome the performance limitations of the traditional ship-type, cylindrical and prismatic FPSO, this paper presents a new concept of sandglass-type FPSO with new sandglass-type float ing body and various function modules. For the sandglass-type model, the heave and pitch motion perform- ance in wave were studied by potential flow boundary element and spectrum analysis methods in frequency domain, and the theories of probability and statistics were applied in the analysis of green water phenome- non. Furthermore, the variable displacement method was used to calculate the statical stability curve. Fi nally, by comparing with the cylindrical floating body model of Sevan Marine Company in Norway and oc- tagon floating body model of CNOOC in China, it was found that the design of sandglass shape could obvi ously improve the stability and hydrodynamic characteristic of FPSO. Thus this paper provides an innova tive engineering platform for the development of deepwater oil and gas.
