破损部位装载方式对破舱稳性的影响

Influence of the Damage Position and Loading Conditions on Damage Stability

船舶破损后,大部分不会马上倾覆,但其稳性却会恶化.为了得到破损部位及装载方式对破舱稳性的影响,按照自由纵倾方式,采用增加重量法,应用NAPA软件计算完整船舶和不同破损位置的破损船舶在不同载况和装载方式下的浮态、稳性及破舱稳性,对典型破损船舶进行调平处理,计算调平后的浮态和破舱稳性.结果表明,可以通过避开不利的破损部位或者选取合理的调平方式来改善破舱稳性.

Most of the ships do not capsize at once after damage,but their stability will deteriorate.In order to get the influence of the damage positions and loading conditions on damage stability,according to the free trim and the added weight method,applying NAPA,the floating state,stability and damage stability of the intact ships and damage ships with different damage positions in different loading conditions have been calculated.After that,some typical damage ships have been leveled,and the floating state and damage stability of the leveled ships have been calculated.The results indicate that avoiding the disadvantage damage positions or selecting reasonable leveling is able to improve the damage stability.
