Cumulative Lifetime Loadings for Naval Ships
Abstract
The seaway loadings upon ships are inherently random in nature and can best be described by probabilistic methods. The primary loadings are those that cause a response of the overall hull girder and consist of vertical bending moments, lateral bending moments, and torsional moments. Since it is highly probable that these loads can be severe, it is important to predict the maximum lifetime or extreme values. Of equal concern is the cumulative effect of all of the waves upon the fatigue life of the ship. This paper presents a probabilistic method for predicting both the extreme and fatigue loadings in a unified and consistent manner.
