Analytical method of ship vibration response which are utilizing at design stage were reviewed for various external forces. Database method proposed by authors were compared with ordinary empirical formula. Database method to estimate Accelerance of ship hull vibration which means Acceleration per unit exciting force at ship end were described. For 6 kinds of combination of vibration variables, effect of factors upon vibration response were investigated by histogram and regression analysis. Results of analysis were largely scattered due to complicity of phenomenon and few number of data. It is found that correlation of Accelerance and displacement of ship is stronger than that of Accelerance and ship logarithmic decrement.
