This time again, the authors studied on practical application for the analysis, applying the new longitudinal strength of the thin-walled variable cross-section beam taking into consideration of "warping in bending". We applied automatic calculation system of first report to box type, double hul B/C, container, double hull tanker of medium size (med. DHT) with multi-cell in the cross-secion. And total warking hours of the system was very short in comparison with those of the conventional system. In this paper, at first, we deveroped the new system to add some new ideas to conception of the first report and it was possible to apply to double hull girder with some longitudinal bulkheads. Next, we applied the new system to some kinds of double hull ship, B/C, container, med. DHT, VLCC and ULCC type with some longitudinal bulkheads and confirmed that the system was operated properly. Total working hours of applying the present method was about one-fifteenth as long as those of applying the conventional method, and it was possible to automatic calculation. And then, taking account of the effects of warping in bending, the new longitudinal strength theory of a hull girder is considered to have reached the stage for practical application.
