Abstract:

As part of the Navys program to develop mobile port facilities, an analytical model has been developed to compute the relative motion between vessels in regular and random seas. The model, which considers all six degrees of vessel motion, is based on strip theory and is suitable for analyzing all single hull, linearly moored vessels. Ship motion and wave data obtained during recent Offshore Discharge of Containership 2 OSDOC II field tests were used to validate the model. The results presented herein suggest that the model closely predicts the absolute motion of ocean going vessels 2,000 tons and larger, but that its predictions of lighter motions when the lighters are in close proximity to larger craft are less accurate. The probable cause of this disparity is hydrodynamic interaction, an effect which is not presently considered in the model.
