An outline of the whole probabilistic concept of ship subdivision
is given, comprising the latest advances in determination of pi
and s1 factors - the two probabilistic factors that form the basis
of the new regulations.The method for calculating the pi factor
for dry cargo ships is thoroughly presented and compared with the
original method, developed by IMO inthe late 60's for passenger
ships. After that, a review is presented of the past efforts to
develop an estimate for the factor si - the most difficultand
controversial part of the new subdivision regulations based on the
probabilistic concept. This may facilitate our present efforts in
developing a sound assessment, consistent with the results of
damage stability model tests. A new method is provided regarding
the capsizal probability, based on the theory underlying numerical
simulations of damaged ship behaviour in natural sea conditions,
assuring a high accuracy of prediction for the si factor.
