Abstract: The calculation method of the damage stability of ro-ro passenger ships is discussed in view of the calculation requirements according to relevant regulations. This paper introduces in detail the calculation preparation, initial calculation conditions, calculation process and results, as well as the requirements of special water areas for the damage stability of the ro-ro passenger ship. The calculation process of the damage stability is analyzed and presented for a 2800-passenger luxury ro-ro passenger ship. The results show that the margin of the subdivision index of mature ro-ro passenger ship design is relatively small, and the subdivision index at the deepest subdivision draught is the smallest. In the case of hull side damage, the initial metacentric height is generally required to be the largest at the deepest subdivision draught. However, the initial metacentric height required for the deep draught is relatively large in the calculation of the accumulation of water on the deck.
