超大型液化气船结构设计要点

Key Points of Structural Designof Very Large LPG Carrier

为合理设计超大型液化气船,依据相关规范、规则对目标船型的低温材料性能与主船体货舱区结构、A型独立舱结构布置进行对比分析,选取合理的低温材料运用范围,确定货舱区主船体与A型独立舱钢材材料,考虑力的传递、施工便利与客户使用等因素,设计合理的结构形式,布置最优检修通道。

For the reasonable design of very large LPG carrier,the low-temperature performance of the target ship,structure in main hull cargo area and structure arrangement of type A independent tank to be carried out were analyzed according to the relevant rules and specification,so as to select reasonable use range of low temperature steel to determine steel material in main hull cargo area and type A independent tank. Consideringthe transmission of force,construction convenient customer useand other factors,the reasonable structure formand the optimal passage way were designed.
