The recent IMO Resolution MSC 19(58) points towards a more
rational way of obtaining subdivisions in ships to ensure a
sufficient stability in damaged conditions.In the preliminary
phase of ship design it is important to know how the attained
subdivision index and the possible oil outflow in a collision are
influenced by the actual positions of the watertight bulkheads.
This information should be given in form of sensitivity factors
yielding the change in attained index, subdivision and oil outflow
for specified changes in the position of user-defined bulkheads.In
the paper such a procedure will be described. The formulation is
quite general implying that future improvements in the damage
stability regulations can be easily implemented.Furthermore,
information of oil outflow from damaged cargo tanks is included.
By that, both the probability of zero outflow, average
hypothetical oil outflow as well as mean local outflow are
presented. The procedure can thus be used to compare the
environmental damage to be expected from different type of oil
tankers in a given collision scenario.
