Abstract: Fatigue is often considered to be a problem of secondary importance in naval architecture. The correctness of this opinion will be investigated in this article. For this purpose the loading of the longitudinal structure of a modern dry cargo ship is analyzed. Attention is given to slamming, temperature stresses and local stresses due to waterpressure. In this article any overestimation of the fatigue loading has been avoided. As a consequence several procedures and calculations could be kept simple. The resulting “minimum” fatigue loading of the ship proves to be rather severe. Some general conclusions about structural design are presented.
