Theoretical Methods in Ship Maneuvering,

Abstract

The classical theory of ship maneuvering is based on the differential equations of motion which apply to the irrotational flow past a rigid body in an ideal fluid. To these are added semi-empirical corrections to account for viscous, free-surface and lifting-surface effects. Most theoretical models neglect viscous and free-surface effects, and treat lifting phenomena under the assumptions that the ship hull is slender, and that the lateral motions are small by comparison to the forward velocity. Theoretical methods are especially useful in shallow or restricted water, and in the related situation where two vessels are in close proximity. Recent results based on the slender-body approach are reviewed, and compared with experiments. Suggestions for future research are outlined. (Author)
