...Madjid Karimirad; Torgeir Moan Proper performance of structures requires among other things that their failure probability is sufficiently small. This would imply design for survival in extreme conditions. The failure of a system can occur when the ultimate strength is exceeded (ultimate limit...

The ship intact condition is the probable condition of the ship at the time of the collision in terms of draft, trim, heel, intact stability, and the permeability of the flooded spaces. The understanding of this condition assists...

... variability of wave-kinematics need to be considered during the deck-wetting process. In the present study, we have used a multidimensional Gaussian formulation of incident wave-kinematics to derive a joint probability density function of deck-wetting (or exceedance) duration and its spatial extent. We have...
