The authors present the results of theoretical evaluations of the heaving and pithing motions, shearing forces and bending moments acting on ship hull of a supertanker in regular head waves. The theoretical calculations were made for the full load condition and the ballast condition, and the followings were found: (1) The ship motions are severe in the case of full load condition, and the heaving motions are more severe than the pitching motions. (2) The midship bending moments are larger in the case of ballast condition than in that of full load. (3) The maximum shearing forces along the ship length are larger in the case of ballast condition than in that of full load. (4) The maximum bending moment occurs at the position near the midship, and the maximum shearing forces occur at the positions nearly (L/4) apart from the midship. These positions sfift foward at high speed, and those tendencies are remarkable in the case of full load condition and not so in that of ballast condition.
