基于DNV-GL规范要求，对某大型双燃料集装箱船B型LNG燃料舱结构进行疲劳强度研究。根据规范给出燃料舱及其支撑结构的疲劳分析流程以及疲劳热点筛选方法，分析不同关键节点的疲劳强度，并提供改善疲劳问题的优化设计方案。为配置B型LNG燃料舱的相关船型的设计开发提供参考。
Research on the fatigue strength of type B LNG fuel tank for large duel fuel container ship is carried out based on DNV-GL Rules. Fatigue analysis process and hot spots screening method for fuel tank and its supports are given. The fatigue strength of various critical locations are analysed and corresponding optimized design solutions are provided. The research results can be refered for design and development of related ships equipped with type B LNG fuel tank.
