The connections between the longitudinals and the transverse webs in ship structure have been weak points in the fatigue strength and neck points in the construction. The authors have developed a new slot structure Kawasaki Apple Slot that can ensure the structural safety and the constructional easiness. The new slot structure has no connections between the longitudinals and the stiffeners on the transverse web which are hard spots in the conventional slot structure, having special-shaped slots (apple shape) suitable for stress relaxation to compensate the elimination of the stiffeners on the transverse web. This paper discusses a wide range of strength analyses and various experiments using structural models that the authors conducted before applying this new slot structure to a 280,000 DWT double-hull VLCC.
