Abstract: It has become obvious that modern ships suffer from problems related to their seakeeping-behavior, which is mainly related to large amplitude roll motion in head and following seas. As these effects are not covered by the existing intact stability criteria, an additional concept was developed. This new concept allows us to quantify the risk of the occurrence of large roll angles by calculating a capsiz-ing index. The question left open so far was, how much stability would be required for a certain ship to meet a distinct safety level against capsizing. This paper presents an approach addressing this ques-tion based on the analysis of some real capsizing acci-dents analyzed by applying various criteria proposed in the past, in comparison to the new intact stability index. For this purpose our simulation code, ROLLS, was applied, taking into account relevant effects such as cargo shift, additional heeling moments and water in-gress.
