Abstract

A high-speed ship mostly experiences the excessive motions in seaway that influence wave loads act to ship’s hull extremely. For this reason, the structure of a high-speed ship must be designed more strength than a low-speed vessel. In this paper, the construction design of the high-speed ship with material of CFRP are evaluated consider to the vertical bending moment under various wave excitation conditions. The eight design variations of the midship section are proposed to be evaluated against the uncertainty load stress due to the vertical motions of ship in random wave. The diffraction theory is adopted to solve the random wave loads due to various wave condition of heading angles, heights, and periods in which the maximum vertical bending moments of the rigid ship are obtained. Structural reliability analysis is applied for assessing structural safety and reliability of the ship’s structure. The structural strength of the construction design which are required for the reliability analysis have been developed based on permissible stress of BKI regulations. Safety levels associated with each mode of failure of all construction designs are determined and compared. Finally, the construction design is selected with the safety index 1.07.
