摘　　要：以中横剖面的面积最小为目标函数,应用自适应步长随机搜索法,对34万吨级FPSO中横剖面进行了优化设计,并将规范设计结果和优化设计结果进行了比较,优化效果较好。　 With the discovery and exploitation of large oil fields at sea, FPSO has become the focus of the shipbuilders′ research. Optimum design is implemented to the 340,000 DWT FPSO in order to minimize the area of the transverse section of the midship. The self-adaptive step random search method is applied in this paper. The comparison between the results of rule-design and optimum design is also given. It shows that the transverse section of the midship is well optimized.

关 键 词：FPSO 结构优化 自适应步长随机搜索法
