This work deals with a fatigue damage assessment of a double hull oil tanker structural detail based on a local structural finite element model. The wave-induced vertical and horizontal bending moments, as well as local pressure loads have been considered in the fatigue damage calculations. Stress analyses are performed based on hot spot and notch stress approaches. The stress distributions at the notch surface of weld toe are studied. Two hot spots are analyzed at the weld toe located between the flat bar stiffener of a transverse web frame and the flange of a longitudinal stiffener at the side shell of a tanker ship hull.
