Motion Analysis of a Trolley Interface for Ship-to-Ship Cargo Transfer

The goal of this thesis is to investigate the effectiveness of a trolley interface for ship-to-ship cargo transfer. The new interface alleviates some of the torsional problems associated with existing ramp designs and can be effectively utilized for both skin-to-skin and Roll-On Roll-Off operations. A mathematical model is developed in order to predict cargo transfer rates in a seaway. Three dimensional hydrodynamic analysis data are used to calculate expected transfer rates in a seaway between a ship and a discharge facility. Results are presented in standard fully developed Pierson-Moskowitz sea spectra. It is shown that the new design is a viable alternative to existing methods.
