Abstract : Response Amplitude Operators (RAOs) are predicted by two ship motion computer models for four container vessels, two discharge lighters, and two barges. The response of each vessel in surge, heave, sway, pitch, roll, and yaw is computed as a function of wave exciting frequency for head, quartering, and beam seas. Computations were carried out for both heavy and light loading conditions of the containerships while the discharge lighters and barges were lightly loaded. Differences in the mathematical models for the ship motion programs are discussed and compared. The primary objective of the report was to make RAO data available for the vessels considered in this study (Author).
