Ten damage stability items that should be calculated differently 

Based on a single formula – “Attained Subdivision Index ≥ Required Subdivision Index” – the principle of probabilistic damage stability is apparently simple. However, in practice,  probabilistic damage stability calculations have made overall damage stability calculations  more complicated. This is especially true for cruise ships, which have complex geometry,  with numerous tanks, connections, compartments and spaces of different categories below  and on the bulkhead deck.

Despite probabilistic rules having been in force since SOLAS 2009, there remains no  uniform way to calculate damage stability: calculation principles depend, in large part, on  the interpretations of the individual performing the calculations.

This paper describes ten typical example scenarios often seen in damage stability  calculations, which – according to Foreship’s opinion – should be calculated differently.
