The paper is a part of the study program, which is built the analytical method and its practical application of the new longitudinal total strength of a hull girder taking in the effects of warping in vertical and horizontal bending and in torsion on wave. Until now, one of the authors studied on the analytical method (ref.1, 2) and its practical application (ref.3, 4, 5 ie VB-warps) of the new longitudinal strength of the thin-walled variable cross-section beam taking into consideration of warping in vertical bending. In this paper, at first, we studied on practical application system (HB-warps) for the analysis, applying to the new longitudinal strength of a hull girder considering the effects of warping in horizontal bending. Then we developed the new system to add some new ideas to conception of VB-warps. The new ideas are that a integration path of starboard side is the position of reflected image with respect to the one of port side, and the new concept of covered cell is applied to a cross-section of PCC type. it was possible to apply to B/C type, closed deck type and PCC type. Next, we confirmed that the system was operated properly and obtained the practical acuracy of calculation.
