摘　　要：3000 DWT LNG燃料动力散货船的燃料储罐基座及其支承结构强度,是保证LNG燃料储罐装置安全的基础。本文采用板梁组合模型对其结构建立有限元模型,根据规范的载荷要求对其进行数值计算分析。计算结果表明,其最大的von Mises应力在许用应力范围内,满足规范要求。The strength of LNG fuel storage tank foundation and its reinforcement structure of 3000 DWT LNG single fuel bulk carrier is the basis to ensure the safety of LNG fuel storage tank device,and the local strength analysis of relevant structures needs to be carried out according to CCS rules.By creating the finite element model of its related structures by plate beam composite model,the numerical computation and analysis are carried out according to the load requirements of the rule.And the calculation results show that its maximum von Mises stress is within the allowable stress range,that is,the strength of LNG fuel tank base and hull support structure fulfils the requirements of the codes.
