摘　　要：中船重工702所研发了二代稳性验证评估软件平台,为二代稳性数值评估提供了方便实用的服务平台。结合两层横准和702所开发的稳性评估软件平台,进行了十余条船舶样船参数横摇分析,发现C11集装箱船没有通过第一层和第二层横准。在样船分析基础上对C11船舶参数横摇发生敏感因素进行了分析,包括舭龙骨面积和重心高。针对该船,进行了船艏和船艉船体型线的改进,达到了改善参数横摇的目的。Based on the IMO vulnerability criteria of level 1 and level 2, assessment sottware of second generation intact stability has been developed by CSSRC, which provides with a fast and convenient calculation service platform on numerical evaluation of the second generation stability. In this paper the parametric rolling stability assessment of more than ten ships is performed, and it is found that the containership C 11 fail to pass the vulnerability criteria of level I and level 2. Sensitive factors of parametric rolling for the containership C11 including bilge keel area and the height of gravity center are analyzed. Finally, the hull forms at bow and stern of the containership are modified and reduction of parametric rolling is achieved.
