On the time domain simulation of second order wave forces and induced responses
This paper is concerned with the time domain simulation of the second order motions of a moored vessel when the random seastate is represented as a sum of harmonic components. It is known that in these circumstances successive runs of a simulation program produce different results for the statistical moments of the response. Here, the variation of the first four statistical moments of the response over an ensemble of program runs is investigated, leading to an assessment of the likely accuracy of these quantities as predicted by a limited number of program runs. Also, it is shown that an approximate simulation method which uses deterministic wave amplitudes and random phase angles does not correctly predict the fourth moment of the response.
