The finite strip method has been shown to be time-saving in computer analysis and efficient in analysis of axi-symmetrical structures and plate structures whose sections are uniform. K. Yoshida et al. did numerical analysis by means of the combination of the finite strip method and finite element method, using the deflection function of Y. K. Cheung along the short side of a strip element, and showed the effectiveness of the finite strip method for bulkcarrier analysis. In this paper, we developed the bulkcarrier analysis program of finite strip method, using the finite difference approximation for deflection along the short side of a strip element, as a simplified method for the purpose of initial design of a bulkcarrier. With this program, we got a good correlation between experimental results and analyzed ones of both actual and model ships of bulkcarriers.
