Novel Research on the hatch corner's fatigue life of a V-shape non-ballast water ship

A novel method to calculate the hatch corner's fatigue life of the V-shape non-ballast ship is proposed in this paper.The proposed method comprehensively studies the wave data provided by integrated marine decision support system, from which both the scatter diagram and operational profile are obtained through programming.The load for the operational profile is calculated with SESAM and the hot spot stress is acquired through ABAQUS modeling.Finally, the structural fatigue life is calculated.It is concluded that the hatch corner's fatigue life of the V-shape non-ballast ship is extended after hatch optimization.
