摘要：Significant drift phenomenon of platform with mooring system is often observed in deep sea. It would be incorrect if the traditional perturbation expansion method was adopted to investigate the wave-body interaction directly. In order to solve the problem, a twice expansion method in time-domain is proposed here. The analysis method is applied for forced motion of truncated cylinder and couple motion of a Spar platform in bichromatic waves. The numerical results show the correctness of the theory and the necessity of the present method. Copyright ? 2015 by the International Society of Offshore and Polar Engineers (ISOPE).
