This paper introduces the total factor error (TFE), an index of correlation of predicted and measured transfer functions for ship motions and wave loads. TFE is defined as the ratio, expressed as percent, of the sum of weighted squares of the difference between the magnitudes (gain factors) of predicted and measured transfer functions to the sum of the weighted squares of the measured value. The wave spectrum of a given sea state is used as the weighting factor. Thus the error of predicted transfer function at a particular wave frequency is weighted by a measure of its importance. Eliminating the visual judgement and the use of words from experimental validation of computer-predicted transfer functions, TFE is an efficient, as well as objective, means of ensuring the reliability of the computer-predicted transfer functions for ship responses.
