6500m~3液化气运输船鞍座结构强度分析

论述中小型液化气船C型独立液货舱液罐鞍座结构及其作用,根据《散装运输液化气体船舶构造与设备规范》,采用有限元分析方法对一艘6 500 m3液化气船的鞍座及其附近船体结构在不同工况下进行了结构强度评估。通过计算分析,提出具有一定工程参考价值的修改建议,为确保6 500 m3液化气船在不同工况下的安全性提供技术保证。

Strength analysis of saddle for 6 500 m3 liqueifed gas carrier

The paper discusses the structure and the functions of the saddle on independent type-C liquid cargo tank for the small and medium liqueifed gas carriers. The structural strength of the saddle on a 6 500 m3 liqueifed gas carrier and the hull structure around it is assessed by the ifnite element method according to the“Rules for the Construction and Equipment of Ships Carrying Liqueifed Gas in Bulk”. Several practical suggestions are proposed through calculation and analysis, which could provide technical supports for the safety of the 6 500 m3 liqueifed gas carrier under different operation conditions.
