Sea states database:
H,T,, probability of occurrence
Discretization of the
database, selection of the
representative sea states,
computation of responses
for that subset
Order of magnitude:
102 to 103
Summation of damages with
the probabilities of occurrence
Systems database:
H,T,, probability of occurrence
Sea states database:
H1,T1,1, H2,T2,2, H3,T3,3, joint probability of occurrence
Discretization of the sea states
database results from that of
the systems, selection of the
representative sea states,
computation of responses for
that subset
Order of magnitude:
106 to 109
Summation of damages with the
joint probabilities of occurrence
Systems database:
H,T,, probability of occurrence
Discretization of the systems,
selection of the representative
systems, computation of
responses to single systems
ICA
Combination of damages
and summation with the joint
probabilities of occurrence
Order of magnitude:
102 to 103
Joint probabilities of
occurrence
Order of magnitude:
106 to 109
