Abstract
The statistical distribution of parametric induced roll angles is estimated using the first order reliability method (FORM), well-known from structural reliability problems. To illustrate the proposed procedure the roll motion is modeled by a simplified non-linear procedure taking into account the time-varying restoring moment and the heave acceleration. The result is the mean outcrossing rate of the roll angle together with corresponding most probable wave scenarios (critical wave episodes), leading to specific maximum roll angles. The procedure is computationally very effective and can thus be applied for determination of ship specific combinations of heading, speed and sea states to be avoided.
