A STUDY ON THE DETERMINATION OF DESIGN WAVE CONDITION

A method to estimate severest sea conditions for a particular response of a ship or offshore structure is proposed based on Fukuda's long-term prediction method. Various wave statistics data are compared and examined from the view point of the estimation of maximum response level in the long term, and Hogben's new data is considered to give a reasonable basis for this kind of study. Comparative calculations are made for vertical bending moment and lateral acceleration of a container ship and scaled ships. From the results it is considered that the rational setting of severest sea conditions is possible by the proposed method, and that a new methodology can be developed to set design values of wave-induced responses by the analysis of short-term responses in the determined sea conditions. The author hopes, through the application of the proposed method, that design values of responses with significant non-linearity can be dealt with more easily, and a better relationship between ship design and ship operation can be established.
