Ship Motion Trade-Off Analysis for the Container Offloading and Transfer System (COTS)

Abstract

Ship motion Response Amplitude Operators (RAOs) were predicted for three containerships and three lighter vessels. Ship motions (surge, heave, sway, pitch, roll, and yaw) were also computed for three sea spectra: a Pierson- Moskowitz, a Bretschneider, and a Bretschneider plus swell. Ship and crane motion data for head, quartering, and beam wave incidence angles are presented in tabular form with plots comparing barge motion RAOs given as a function of wave incidence angles. Significant displacements, velocities, and accelerations were calculated in each of the three coordinate directions for various rigid boom crane configurations. A sample procedure is presented for using the large volume of motion data available for the Container Offloading and Transfer System (COTS) system design.
