9500 m^(3)多用途液化气船破舱稳性影响因素敏感性分析

Sensitivity Analysis of Damaged Stability Influencing factors of the 9 500 m^(3) Liquefied Gas Carrier

以一型最新交付的9 500 m^(3)多用途液化气船为研究对象,研究不同影响因素小幅度变化对船舶破舱稳性的影响,并以满足破舱稳性要求的空船极限重心高度为评估标准,得到该型船破舱稳性不同影响因素的敏感性。研究结论可用于尺度相近的同类型船的破舱稳性优化,依据破舱稳性影响因素的敏感性,结合破舱优化需求,选择最优的方案。

The influencing factors of damaged stability were studied including the main dimensions of the ship,the initial conditions of damage,the number of subdivisions on the ship side and so on.The recently delivered 9 500 m^(3) liquefied gas carrier was taken as the research object,and the effects of small changes in different influencing factors on ship damaged stability were analyzed.The limit height of the ship's lightweight center of gravity was taken as the evaluation criteria,and the sensitivity of different influencing factors of the vessel was obtained.The study could be used to optimize the damaged stability of the vessels with similar dimensions to choose the optimal scheme according to the sensitivity of the influencing factors of damaged stability and optimization requirements of damage.
