A direct spectral analysis method is used for the fatigue analysis of an offshore jacket structure subjected to random wave excitation. Hence the stress range power spectral density function matrix is evaluated in a form that can be calculated directly and conveniently, without the evaluation of the input force spectral matrix required by a full spectral analysis. The results should be identical to those of the full spectral method, if both methods retain the same number of modes, and differ from the approximate ones of the reduced spectral method.
