WebbThis paper presents an experimental investigation on the slow-drift oscillation of a semi-submersible. The soft-moored model was subjected to two sea states for studying the slow-drift response in irregular waves. The effect of wave direction was considered by setting the vessel in head, quartering and beam sea. WebbA ship at sea is subjected to a number of forces causing the structure to distort. Initially, these may be divided into two categories, as follows: Static forces – Ship floating at rest in still water. Two major forces acting: the weight of the ship acting vertically down buoyancy acting up Dynamic forces – due to the […]
