Effects of short crested seas on the motions of a trolley interface for ship-to-ship cargo transfer

摘要

This thesis sets out to explore the effects on the dynamic response of a hybrid trolley system employed in ship to shore cargo transfer operating in a realistic short crested irregular seaway. Compared to the uni-directional long crested waves, the multi-directional nature of short crested waves enhances the realism of the modeling. A standard cosine-squared spreading law was added to the two-parameter Bretschneider spectrum. The results provide added data on the coupled system response in all directions and moderate any overestimation that may be derived from simply using long crested waves.
