The objectives of present paper are to derive the approximate solution for comparatively easily computing the sea shock forces on developing numerical simulation method of sea shock force and to clear the effect of sea shock forces on very large floating offshore structures by the present approximation. Therefore the approximation solution and the boundary integral equation method on frequency domain are derived to understand fundamental characteristics of sea shock force. Further the accuracy and the usefulness of the present approximation is confirmed by comparing the results by the present approximation with the numerical results by the boundary integral equation method. Sea shock forces on very large floating structure are concretely understood by transforming numerical results in frequency domain into numerical results in time domain and basic data of earthquake-resistant design which is very important for implementation design is obtained.
